Vehicle hands-free phone kits are becoming increasingly popular to vehicle drivers and mandatory in multiple continents, such as Europe and some states in the United States, for vehicular safety reasons. These phone kits allow a vehicle driver to make and receive phone calls with a cellular phone “hands-free,” i.e., without physically handling the phone in order to access its functionality and associated functional controls. A simple hands-free phone kit typically includes a headset with an attached microphone that may be wire-connected to a cellular phone. This type of hands-free phone kits is inconvenient to the driver because of the dangling wire connection that may interfere with the driver's operation of the vehicle. Another type of conventional hands-free phone kits includes a separate speaker that may be wired or wirelessly connected to a cellular phone. However, the separate speaker often provides poor audio quality. There also exist wireless hands-free phone kits that includes a universal transmitter that may be clipped onto a cellular phone's earpiece and wirelessly transmits, via FM modulation, audio received by the phone during a phone call to a vehicle audio system. Thus, the driver is able to listen to phone calls made from or received by the cellular phone through existing speakers in the car audio system. This type of hands-free phone kits also suffers from poor audio quality because of the often poor quality of the microphone that accompanies the universal transmitter and the precarious nature in which the universal transmitter is attached to the earpiece of the cellular phone for audio reception. Alternatively, there exist higher quality hands-free phone kits that are typically more expensive and complex because they require special installation to leverage each particular vehicle audio system.
The advent of Bluetooth wireless technology and Bluetooth-enabled cellular phones provides vehicle makers, such as automobile manufacturers, with the necessary tools to integrate hands-free wireless communication capability with their car audio systems. For example, some automobile manufacturers offer special car audio systems with built-in Bluetooth wireless technology and microphone in newer car models to provide drivers with access to the phone functionality of their Bluetooth-enabled cellular phones through the car audio systems. However, automobile manufacturers typically charge a premium for such integrated hands-free phone functionality with dedicated functional controls in specialized factory-installed car audio systems, which are only available for selected new car models and cannot be leveraged for existing car audio systems in older-model cars or car models from other automobile manufacturers.
Portable content players and other devices capable of playing content, such as media like music or videos, are also becoming increasingly popular and are typically designed to play the personal content of users. Users tend to use multiple media devices, such as an MP3 digital music player, wireless or cellular telephone, personal digital assistant (PDA), personal computer, and a car audio system, and many of these devices are capable as content players for playing the personal content of the users. However, there is currently no fast and convenient way to transfer content between a user's multiple devices. Furthermore, the devices tend to have different user interfaces, so it is inconvenient for a user to learn and operate each device to play music or other content. For instance, some automobile manufacturers offer connector kits for connecting portable music players, such as MP3 players, to the car audio systems in their vehicles. However, these existing connector kits require users to wire connect the portable music players to docks, which further are wire connected to the car audio systems in the vehicles. When a portable music player is docked, its own user interface (display and control buttons) is typically disabled, and the user must use the control buttons belonging to the vehicle's car audio system for limited control of the docked portable music player. Furthermore, the user is typically provided with a limited display of a numeric number to indicate the playing track on the vehicle's dashboard display. Other existing vehicle connector kits are capable of adopting the title navigation of a portable music player for display on a vehicle's dashboard to provide more detailed content information to users. However, such connector kits also require the docking of the portable music player and disabling of the player's user interface (displays and control buttons) when the player is docked.
Accordingly, described herein are embodiments that facilitate: hands-free wireless communication capability for new and existing vehicles, wireless transfer of content from a content source to a content player, or both to provide users with safer, more user-friendly and convenient manners to remotely access a wireless communication device and/or content source.
Accordingly, in one embodiment, there is provided a method for providing hands-free access to a wireless communication functionality of a wireless communication device comprising the steps of establishing a wired communication link from a wireless adaptor to a content player, the wireless adaptor is separate from the content player and removable from the wired communication link with the content player, establishing a wireless communication link through a wireless proximity network from the wireless adaptor to a wireless communication device, receiving, through the wired communication link, a request from the content player for access to at least one functional control of the wireless communication device, responsive to the request, providing the content player with the access to the at least one functional control of the wireless communication device, receiving at the wireless adaptor a signal for a remote access of a wireless communication functionality of the wireless communication device, and the wireless adaptor facilitating, through the wireless communication link, the remote access of the wireless communication functionality of the wireless communication device.
In another embodiment, there is provided a computer readable medium on which is encoded program code for facilitating hands-free wireless communication functionality and wireless transfer of content, which comprises program codes for establishing a wired communication link with a content player, detecting a presence of a wireless communication device in proximity of the content player, establishing a wireless communication link with the wireless communication device based on the detection of the presence of the wireless communication device, receiving content stored in the wireless communication device via the wireless communication link, routing the content, through the wired connection, to the content player to facilitate playback of the content at the content player, and providing remote access to a wireless communication functionality of the wireless communication device via at least the wireless communication link.
In still another embodiment, there is provided a wireless adaptor for providing hands-free access to a wireless communication functionality of a wireless communication device, the wireless adaptor comprising a wireless interface operable to form a wireless proximity network with a wireless communication device to remotely access a wireless communication functionality of the wireless communication device, and a wired interface that facilitates a wired connection with a content player to facilitate a remote access of the wireless communication functionality of the wireless communication device at the content player, wherein the wireless adaptor is separate from the content player and removable from the wired connection for another wired connection to another content player.
Embodiments are illustrated by way of example and not limited in the following figure(s), in which like numerals indicate like elements, in which:
For simplicity and illustrative purposes, the principles of the embodiments are described by referring mainly to examples thereof. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It will be apparent however, to one of ordinary skill in the art, that the embodiments may be practiced without limitation to these specific details. In other instances, well known methods and structures have not been described in detail so as not to unnecessarily obscure the embodiments.
1. System Overview
Generally speaking, the content providers 110 provide content to the content service 120, such that the content service 120 may provide several functions. One of the functions includes receiving new content from the content providers 110 on a substantially regular basis. Another of the functions includes making the content received from the content providers 110 available to users. In addition, the content service 120 may receive content from multiple content providers 110 to provide users with a relatively large content selection. Users may obtain the content made available by the content service 120 through, for instance, one or both of subscription services and on-demand services.
The content service 120 may also automatically organize content for users and continually provide new content to users. In addition, the content service 120 may perform other functions, such as billing, user information tracking, historical data tracking, etc. The content service 120 may include a server 121 and a database 122 for storing user information and content. The server 121 may facilitate the downloading of content to the target devices 140 used by the users. It will be apparent to one of ordinary skill in the art that the server 121 may include multiple servers and the database 122 may include multiple databases depending on the size and complexity of the content service 120. For example, to support a relatively large number of users, several servers 121 and databases 122 may be needed to harvest content from the content providers 110 and provide content to users with minimal delay.
The network 130 may represent one or more networks. The network 130 may include one or more of private networks, public networks, such as the Internet, wireless networks, such as satellite and cellular networks, and local area wireless networks, such as Wi-Fi (IEEE 802.11 specifications) or Bluetooth (IEEE 802.15 specifications) networks, wired networks, local area networks, wide area networks, and any other type of communication network.
The content service 120 may provide content to the target devices 140 via the network 130. The target devices 140 may download the content from the content service 120, may receive content from one or more other target devices, or may be operable to both download content from the content service 120 and receive content from another target device. For example, as shown in
2. Overview of Functionality and Advantages of Content Service
The system 100 provides a media experience for users without requiring a user to change conventional behavior to utilize the content service 120 providing the media experience. For example, the system 100 allows a user to play his or her selected audio content, such as music stations, talk radio, personal content, etc., on one of several target devices 140 that the user may be using at any particular time, such as a car radio in the car, a cellular telephone when the user is on the go, a personal computer or home stereo at home. A target device may carry content selected by the user in a set of channels which are seamlessly available throughout the day on any one of many target devices. The system 100 manages the content and ensures the content is automatically replenished as it is consumed. Furthermore, an interface that is the same as or similar to a conventional device interface may be provided on the target devices 140, so the user may play desired content on any target device in a relatively quick and easy manner.
According to an embodiment, the content service 120 allows a user to configure one or more sets of channels for one or more of the target devices 140. Each channel is populated with content from a content provider or content provided by the user, referred to as the user's personal content. A channel is a data set of content, which may be of a particular type of content. For example, the content service 120 may make available hundreds of stations of content or individual pieces of content. Webcast radio and webcast television are some examples of stations of content. The content service 120 may provide one or more of the stations of content to users as a subscription service, where one or more stations are subscribed to by a user and the content for the stations is sent to one or more target devices for the user. In one example, one or more stations provide large or continuous blocks of Digital Millennium Copyright Act (DMCA) compliant streaming content. Some examples of individual pieces of content include single songs or albums, movies, video clips, etc. The content service 120 may provide an on-demand service where a user may purchase and download individual pieces of content.
Furthermore, channels may include content of a particular type, such as a sports talk channel, a popular music channel, etc. A user may configure a set of channels, hereinafter referred to as a channel set, for example, by selecting content provided by the content service 120 and of interest to the user. The channels may include high-quality, digital content, which may be commercial-free in some instances. A channel in a channel set may also include content from a user's personal collection, such as audio files stored on the user's personal computer. This channel may be programmed by play list, genre, or artist, or any other desired category or set of content.
A user may configure several channel sets, such that the user may use different channel sets at different times. For example, a user may create a first channel set for everyday use, such as for commuting to work. This channel set may include a traffic and news channel, a sports talk radio channel, as well as other channels. The user may create a second channel set for long trips, which may include, for instance, a classic rock channel and a comedy channel.
Content for the channels may be downloaded to one or more of the target devices 140 from the content service 120. The content service 120 may also refresh a target device with new content on a substantially continuous or periodic basis. For example, after content in a channel in a target device is consumed by a user, such as after the content is played, or after content becomes stale, such as after a predetermined period of time has lapsed, the content in the channel may be replenished or replaced with new content received from the content service 120 or new content that was cached in another one of the target devices 140. This update of content on a target device may be performed automatically, and may be beneficial for target devices 140 that have limited storage for storing content, such as a PDA, phone, or other device having a relatively small amount of storage space.
In addition, the target devices 140 may each include an interface that is similar or the same as a conventional user interface widely used in at least one type of today's end user devices. Thus, a user may not be required to learn how to use the interface of a target device. Furthermore, a common interface may be provided on several target devices 140 that may be used by a single user to play content. For example, the common interface may be provided on a user's phone, personal computer, car radio, etc. Thus, the user may not need to learn how to use different interfaces for different target devices 140.
The user interfaces of the target devices 140 may emulate or include the user interfaces of conventional radio or music players with channel presets. The interfaces on the target devices 140 may provide for “one-click” channel selection, similar to clicking a channel preset button on a radio. In one example, each channel may include content populated with a type or genre of music pre-selected by the user, which allows a user to switch with one click between channels similar to switching between different radio stations on a radio. The interface may also allow a user to fast forward, rewind, or pause content.
A software application installed on a user's personal computer allows the user to manage and configure channel sets and update content on multiple target devices. Also, the content that is stored on one target device, may also be available on at least one other target device. Furthermore, the same software application or another software application may be provided on a target device that allows a user to flag songs or other content and add them to a personal wish list for purchase. U.S. Patent Application entitled, “Granting Greater Rights to Stored Content” (Attorney Docket Number BCS3804) incorporated by reference above describes this feature.
3. Content Service
The management module 123 may coordinate information between multiple users. For example, the management module 123 may receive channel configuration information from multiple users, which may include user selections of content for channels in one or more sets of channels for the multiple users. The user selections and channel sets configured by the users may be stored in the database 122 along with additional channel configuration information added by the content service 120, such as permissions and special attributes or rules for content consumption, that is related to the user selections and configurations. The database 122 is queried subsequently to determine the content to provide to the users. In one embodiment, the management module 123 generates a web based user interface which allows a user to log into the content service 120, register with the content service 120 and set preferences, and configure channel sets.
For example, a user connects to the content service 120 via the network 130 shown in
Alternatively, the management module 123 may prompt the user for user information, and channels may be selected for the user based on the user information. For example, the user may provide demographic information or a selection of favorite artists. Several channels may be selected for a channel set for the user based on this information. The user may select some of the channels for a channel set. Default channels may also be provided. Also, several channel sets may be configured for each user.
The content distribution module 124 sends content for channel sets to one or more target devices 140. The content distribution module 124 may determine the content to send to the target devices based on the related channel configuration information. For example, the content distribution module 124 retrieves channel configuration information for a selected set of channels from the database 122. In addition, the content distribution module 124 may send content for the respective channels to one or more target devices 140.
The aggregation module 125 receives, for example, content and play lists from the content providers 110 and stores the information in the database 122, such that the content may be distributed to users as needed.
4. Personal Computer User Gateway for Content Service
Several target devices 140 are shown in
Some of the target devices 140 shown in
The personal computer 141 may include an application 170 having a management module 171, an update agent 161, and a user interface 151. The management module 171 generally allows the user to determine and send channel configuration information for configuring selected channel sets to the content service 120. The channel configuration information may include the selection of content to place in the selected channel sets.
Examples of content that may be selected for a channel set may include genre-oriented music stations, talk content, the user's personal content, etc. Genre-oriented music content may be selected from a catalog listing a relatively large number of stations or individual content provided by the content providers 110. In addition, a single music channel may deliver a continuous set of music tracks on a target device. Talk content may also be selected from a catalog of talk content channels, which may be updated periodically, such as hourly, daily or weekly. In addition, content from more than one content provider may be placed in a single channel set. The user's personal content may be stored on the personal computer 141, which the management module 171 may discover. As such, a user may sort through various content in various manners and may move individual tracks of content or large blocks of content to a channel in a channel set.
The update agent 161 generally receives content from the content service 120 and may refresh content 180 stored on the personal computer 141 on a periodic basis. For instance, the update agent 161 caches the content 180 at the personal computer 141. The content 180 may include content received from the content distribution module 124 of the content service 120.
The update agent 161 also controls the transfer of content 180 to other target devices 140. For example, when the cellular phone 142 is connected to or otherwise interfaces with the personal computer 141, content for one or more selected channel sets may be transferred to the cellular phone 142. In one example, the transfer of content 180 may be performed as a substantially automatic feature when the cellular phone 142 is connected to the personal computer 141, whereby the user does not need to issue a transfer command. The update agent 161 may control the transfer of content 180 to the cellular phone 142, such that new content may be experienced from one or more play lists.
In addition, the update agent 161 may control the transfer of content 180 to generally enable the new content to be stored on the cellular phone 142 while staying within the limitations of the cellular telephone's 142 storage capabilities. Thus, at least a portion of the content 180 maybe stored on the cellular phone 142, which is indicated as content 181. Similarly, home devices 144, such as a home stereo or set-top box, may also receive content 180 from the personal computer 141. Instead of a personal computer 141, a server, such as a home media server, or another device may be used to receive and cache content 180 from the content service 120, without departing from a scope of the system 200.
The personal computer 141 may also include a user interface 151 that provides for “one-click” selection of channels and emulates a conventional interface. In one embodiment, the user interface 151 includes a GUI interface that a user may click to control playback and to select a channel. In addition, or alternatively, the user interface 151 may include hardware, such as buttons, wheels, keys, etc.
5. Portable Content Device
A portable content device, such as the cellular phone 142, PDA, MP3 player, and the like, may include an application 174 having a management module 172, an update agent 162, and a user interface 152. The management module 172 generally allows the user to determine and send channel configuration information for configuring selected channel sets to the content service 120, in manners similar to those described above with respect to the management module 171 of the personal computer 141. In certain instances, the management module 172 may be considered optional for the application 174, since management of the application 174 may be performed by the personal computer 141.
The update agent 162 of the cellular phone 142 generally controls updating of the content 181, which may include new content received from the content service 120 via the cellular network 132, the Internet 131, a wireless proximity network such as Bluetooth (IEEE 802.15) or Wi-Fi (IEEE 802.11) as further discussed later, or any combination thereof, as routed from the content service 120 or through the personal computer 141. For example, the content 181 may comprise new cached content received from the content service 120 as routed through the internet 131 and cellular network 132, as shown in
The update agent 162 of the cellular phone 142 may also manage the receipt of content from one or both of the content service 120 and the personal computer 141. More particularly, for instance, the update agent 162 may control the receipt of one type of content from the content service 120 and another type of content from the personal computer 141. For example, the update agent 162 may control the receipt of content, such that, content required to be updated relatively frequently (hot content), such as traffic information, is received from the cellular network 132. In another example, the update agent 162 may control the receipt of content such that hot content is received from the personal computer 141 before such content expires (without going through the cellular network 132 or any other wireless telecommunication network). In addition, the update agent 162 may control the receipt of cold content, which are content that may be updated less frequently, to be received from the personal computer 141. In this example, the personal computer 141 may download the cold content from the content service 120. Furthermore, when the cellular phone 142 is connected to or otherwise interfaces with the personal computer 141, the cold content may be updated on the cellular phone 142. It will be apparent to one of ordinary skill in the art that cold content, such as music, may also be downloaded to the cellular phone 142 via the cellular network 132.
As shown in
Playback of the content 181 may be controlled via the user interface 152 of the cellular phone 142. For example, the user interface 152 may include controls to enable the selection of a preset channel, to rewind, fast forward, pause, play, etc.
Although not shown, the cellular phone 142 may comprise a device configured to provide the functionalities of multiple devices. For example, the cellular phone 142 may include an MP3 player, PDA, camera, video player, etc.
6. Wireless Communication Device
A wireless communication device, such as the cellular phone 142, is operable to provide a user with wireless communication functionality. As referred herein, wireless communication functionality includes functions relating to wireless communication facilitated by a wireless communication device, such as the cellular phone 142, and operation thereof. Examples of wireless communication functionality include but are not limited to initiating an outgoing phone call, receiving an incoming phone call, accepting an incoming phone call, rejecting an incoming phone call, accessing history of phone calls, redialing a phone number, and searching for a name or phone number in stored phone list. In one embodiment, the wireless communication device, such as the cellular phone 142, is also capable of establishing a communication link via a wireless proximity network. As referred herein, a wireless proximity network includes any wireless network that is capable of providing short-range wireless communication links among networked devices. Examples of a wireless proximity network includes but are not limited to personal area networks (PANs) such as Bluetooth (IEEE 802.15 specification) and Wi-Fi (IEEE 802.11 specification). Thus, a wireless proximity network should be differentiated from long-range wireless networks, such as cellular networks for cellular or mobile phones and satellite communication networks.
7. Content Player and Wireless Adaptor
A portable content device such as the cellular phone 142 may send content to a content player such as the car audio system 143 via the wireless interface 150 of the cellular phone 142. As a wireless communication device, the cellular telephone 142 may send and receive wireless communication signals, such as phone calls, to the car audio system 143 via its wireless interface 150 as well. In addition, a wireless adaptor 173 may be used to enable communications between the cellular phone 142 and the car audio system 143 for wirelessly: transferring communication signals to and from the cellular phone 142, receiving content, and controlling playback of the content. Thus, the wireless adaptor 173 presents a cost effective solution for integrating hands-free wireless communication functionality (e.g., phone calls) of a wireless communication device (e.g., the cellular phone 142), into a new or legacy vehicle audio system (e.g., the car audio system 143), wherein wireless communication sessions made through and received at the cellular phone 142 may be routed and controlled (e.g., initiating, accepting, or rejecting calls, volume up/down) through the car audio system 143 and its functional controls, or controlled by a user interface on the wireless adaptor 173. Additionally, the wireless adaptor 173 may add the convenience of displaying call metadata or information (e.g., Caller ID, last dialed number, phone list, and other call history information), which is otherwise available on the cellular phone 142, on a display of the car audio system 143 through use of the functional controls on the car audio system 143 or the available user interface on the wireless adaptor 173. Also, the wireless adaptor 173 may provide seamless integration of the hands-free wireless communication functionality with the playback of an external content, such as audio stream, at the car audio system 143, such as resumption of content playback after a call is completed, interruption of content playback through automatic pausing or muting the content playback when receiving or during a call.
Furthermore, the wireless adaptor 173 may arbitrate access to the car audio system 143 for facilitating the wireless communication functionality or content playback. For example, if both the wireless communication functionality and content playback are facilitated through the same component, such as a CD changer, in the car audio system 143, content playback may be interrupted, as noted above, for the facilitation of the wireless communication functionality, such as a phone call. If the wireless communication functionality and content playback are facilitated through different components of the car audio system 143, such as a satellite radio and a CD changer, respectively, content playback may be interrupted with the wireless adaptor 173 automatically switching the car audio system 143 to CD changer mode to facilitate the wireless communication functionality. Likewise, even when there is no content playback and the car audio system 143 is initially set at a mode other than the CD changer, an initiated wireless communication functionality will trigger an automatic resetting of the car audio system 143 to the CD changer mode to handle the wireless communication functionality.
The wireless adaptor 173 may be a part of or separate from the car audio system 143. In addition, or alternatively, a wired interface other than the wireless adaptor 173 may be used to enable the communications between the cellular phone 142 and the car audio system 143.
In one embodiment, the wireless adaptor 173 uses a wireless proximity network to establish a wireless communication link 310 with the cellular phone 142. Additionally, the wireless adaptor 173 is operable to be wire-connected at 320 to an available I/O interface on the car audio system 143. Examples of such an input connection include but are not limited to an I/O interface for an additional CD changer, a satellite radio, or any other auxiliary (AUX) I/O interface for any other audio component. Because the wireless adaptor 173 may be separate and distinct from the car audio system 143, as noted earlier, it is removable from its connection with the car audio system 143 for connection to another car audio system or any other content player so long as there is compatibility between their I/O interfaces.
In one embodiment, the cellular phone 142 is suitably-enabled to wirelessly transmit communication signals, content, and command/control signals, encoded or unencoded, via the aforementioned wireless proximity network to the wireless adaptor 173. In turn, the wireless adaptor 173 provides any needed signal conversion or decoding of such content and command/controls for forwarding to the car audio system 143. Thus, the wireless adaptor 173 provides an interface that allows the cellular phone 142 to: a) integrate its wireless communication functionality with the car audio system 143; b) transmit stored content to the car audio system 143 for content playback by the car audio system 143; or c) do both.
Once the content and any associated metadata are decoded, they are forwarded to the car audio system 143 via an input/output (I/O) interface 450, which may be a part of the wireless adaptor 173 as shown in
The commands translation module 490 includes program code, encoded on a CRM, suited for translating command/control signals between the cellular phone 142 and the car audio system 143, as facilitated by the wireless proximity network and the I/O interface 450. In one embodiment, it is possible to include in the program code any standard or generic audio or video profile so that the wireless adaptor 173 is operable with different car audio systems from different manufacturers that use such standard or generic audio or video profile. For instance, different manufacturers may use the same standard audio or video profile for controlling one or more components in their car audio systems, such as the preset station buttons and the station seek up/down buttons of a car radio component. Thus, it is possible to leverage such standard audio or video profile to translate command/control signals from the car audio system 143 for both content playback and hands-free wireless communication functionality back to the cellular phone 142 for different types of car audio system. Likewise, the I/O interface 450 may be a standard or generic I/O interface so that the wireless adaptor 173 is operable to be connected to the I/O interface of different car audio systems from different manufacturers that have such standard or generic I/O interface. For instance, different manufacturers may include the same standard I/O interface for input and output of control signals relating to one or more components in their car audio systems, such as the control signals for the car audio component, the CD player component, or both.
In another embodiment, the wireless adaptor 173 is specific for the car audio system 143 of each manufacturer, wherein the commands translation module 490 includes program code that is specific for the audio or video profile that is proprietary to the particular manufacturer. In such instance, the proprietary audio or video profile may be obtained from the particular manufacturer. Alternative embodiments are contemplated, wherein updated software code may be wirelessly downloaded from the cellular phone 142, or any other suitable device by wired or wirelessly, to the wireless adaptor 173 in the same manner as content is transmitted from the cellular phone 142. Thus, the commands translation module 490 in the wireless adaptor 173 may be provided with software updates for the component in the car audio system 143 for which it is initially intended or another component in the same car audio system 143 or a different car audio system for which it is to be intended. For instance, a user who wishes to use the wireless adaptor 173 in different cars with different car audio systems may download suitable program code for command/control that is specific for use in each car.
Likewise, when the car audio system 143 is provided with a particular I/O interface by its manufacturer, the wireless adaptor 173 is to include an I/O interface 450 unique to the car audio system 143 to facilitate a successful connectivity between the two I/O interfaces.
To manage the communication links 310 and 320 for hands-free wireless communication functionality between the cellular phone 142 and the car radio system 143 or wireless transfer of content from the cellular phone 142 to the car audio system 143, the wireless adaptor 173 further includes a proximity wireless network manager 430 that runs the application profiles stack 420 to set up and control the wireless communication link 310, interacts with the decoder 440 to decode content and any content metadata, interacts with the speech commands module 460 to receive audio input by the user at the microphone 407, and interacts with the commands translation module 490 and the I/O manager 495 to set up and control the wired communication link 320 for forwarding the decoded content and content metadata to the car radio system 143. In one embodiment, the network manager 430 includes program code, encoded on a CRM, for performing the aforementioned functions.
When the wireless adaptor 173 is in operation, the A2DP therein enables the wireless adaptor 173 to: a) provide hands-free access to the wireless communication functionality of the cellular phone 142 through the car audio system 143; b) wirelessly transfer the content stored in the cellular phone 142 to the car audio system 143 as streaming audio for audio playback through the later; or c) do both. As described earlier, the stored content is located in respective channels in the cellular phone 142. The network manager 430 further controls the content decoder 446 to decode the streaming audio into a format understood by the car audio system 143 for output to the I/O interface 450, to which the car audio system 143 is connected through its own I/O interface. The SPP provides each of the cellular phone 142 and car audio system 143 with a virtual serial port for wireless connection, through emulation of RS-232 control signal communication, between the devices (rather than with an actual serial cable) to form the wireless proximity network. Thus, the SPP may be used in place of the A2DP to transfer content from the cellular phone 142 to the car audio system 143, provide remote control use of the cellular phone 142 by the car audio system 143, and provide remote control use of the wireless adaptor 173 by the cellular phone 142. It should be understood that the SPP defines the serial port emulation for wireless connection via RF communication (RFCOMM). Thus, alternative embodiments are contemplated wherein SPP can be bypassed, and the underlying RFCOMM protocol can be used directly to provide emulation of a serial port for wireless connection. The AVRCP also may be used in place of the SPP for wireless connection to ensure interoperability of functional controls between the cellular phone 142 and the car audio system 143, and any available user interface on the wireless adaptor 173 for content access and playback.
As referred herein, a functional control of a device is a control that is capable of controlling a function of such device. Thus, both the SPP and AVRCP enable the cellular phone 142 to be remotely controlled by a remote control 405, voice commands through the microphone 407 (through the wireless adaptor 173), a user interface (e.g., keypad, buttons, etc.) located on the wireless adaptor 173, or the car audio system 143, via the wireless proximity network. For instance, the SPP or AVRCP enables the car audio system 143 to act as a controller that sends audio command/control signals to the cellular phone 142 for playback of the audio stream or phone command/control signals to the cellular phone 142 for wireless communication. In another instance, the SPP or AVRCP enables the user to send audio command/control signals, via the remote control 405 or voice commands at the microphone 47 or a user interface available on the wireless adaptor 173, to the cellular phone 142 for content playback or communication command/control signals for the wireless communication functionality. Examples of command/control signals for content playback include playback, stop, channel selection, and display mode, depending on the nature of the devices involves, namely the cellular phone 142 and the wireless adaptor 173 in this instance, and the desired scenario for accessing the audio stream through the car audio system 143. Examples of command/control signals for wireless communication includes accepting incoming call, rejecting incoming call, hanging up a call, initiate an outgoing call, and any other phone functions that is available through the user interface of the cellular phone 142.
In one embodiment, the wireless adaptor 173 includes a switch to provide the user with an option to either maintain or disable the user interface on the cellular phone 142 for control upon connection of the wireless adaptor 173 to the car audio system 143 and establishment of the wireless proximity network. As a result, the cellular phone 142 is controllable by the functional controls on its own user interface, the functional controls on the user interface of the car audio system 143, the functional controls on the remote control 405, the functional controls on the user interface of the wireless adaptor 173, or the functional controls on any combination of these four devices at any time.
The HFP is included to allow the car audio system 143 to handle incoming phone calls to the cellular phone 142. Thus, the HFP may be used to enable two-way audio and call status between the wireless adaptor 173 and the cellular phone 142 to integrate hands-free wireless communication functionality with the car audio system 173, with associated controls accessible through an available user interface on the wireless adaptor 143 or an existing user interface on the car audio system 173. In one embodiment, when a wireless communication session is externally initiated, e.g., a phone call coming in through the cellular phone 142, the user is notified by an alert tone transmitted from the wireless adaptor 173 to the car audio system 143 via the I/O interface 450, as directed by the wireless proximity network manager 430 and translated by the commands translation module 490. Thus, the alert tone may originate from the cellular phone 142, which is then fed through the wireless adaptor 173 to the car audio system 173. Alternatively, the alert tone may be generated within the wireless adaptor 173 in response to the incoming call. In another embodiment, alternative or in addition to the alert tone, the wireless transmitter 173 transmits an alert text via the I/O interface 450, as directed by the I/O manager based on information from the wireless proximity network manager 430 that is translated by the commands translation module 490, for display at the car audio system 143. The alert text may include text indicating that there is an incoming call, metadata of the incoming phone call, such as a caller ID identifying the caller's number or name, as pre-programmed in the cellular phone 142 or provided by the wireless communication provider. As with the alert tone, the alert text may originate from the cellular phone 142 and fed through the wireless adaptor 173 or be generated by the wireless adaptor 173 in response to the incoming call.
The PAN profile allows the Bluetooth devices involved to participate in a personal area network that is used for communication among devices in proximity to each other. In this case, the involved Bluetooth devices are the car audio system 143 that is Bluetooth-enabled by the wireless adaptor 173 and the cellular phone 142 that is Bluetooth-enabled and in proximity to the wireless adaptor 173 (for example, in the same car where the car audio system 143 is installed). Thus, the PAN profile allows the car audio system 143 to send its status and identification information to the cellular phone 142, via the I/O interface 450 as managed by the I/O manager 395 and translated by the command translation module 490, so as to establish a communication link with the cellular phone 142. The PAN profile also may be used to transfer content from the cellular phone 142 to the car audio system 143 via the wireless adaptor 173.
The ESDP employs a detection protocol that allows a Bluetooth device to discover any other Bluetooth device that is in proximity to the wireless adaptor 173, and hence the car audio system 143, and to establish a communication link with the nearby Bluetooth device over a network (such as a personal area network) with a network profile (such as the PAN profile). Thus, the wireless adaptor 173 supports a detection protocol that enables a target device, such as the car audio system 143, to dynamically detect a portable content device, such as the cellular phone 142, and to automatically interface with the cellular phone 142 for facilitating hands-free wireless communication functionality and content streaming therefrom without requiring any user's interaction. For example, a user having a powered-up cellular phone 142 in a pocket, a brief case, a pulse, or a glove compartment in a car equipped with the car audio system 143 and a connected wireless adaptor 173 does not need to retrieve the cellular phone 142 and activate a communication link with the wireless adaptor 173. Instead, the car wireless adaptor 173 automatically detects the presence of the cellular phone 142, establishes a communication link with the cellular phone 142 via the wireless proximity network, facilitates hands-free phone functionality through the car audio system 143, and initiates the audio streaming from the cellular phone 142 to the car audio system 143, if the car audio system 143 is already on or powered up or upon such powered up. Thus, from the perspectives of the cellular phone 142 and the user, it matters not what target device is connected to the wireless adaptor 173 because of the seamless integration and standardization of functions provided by the wireless adaptor 173.
Accordingly, the wireless adaptor 173 enables the wireless communication functionality of the cellular phone 142 to be used hands-free through existing target devices, such as the car audio system 143, and its stored content to be played and controlled in a natural and intuitive manner with familiar user interfaces already found in existing target devices and with minimal user interaction. Examples of the hands-free wireless communication functionality are now described. In one example, the preset radio-station buttons for a car radio component of the car audio system 143 are operable to accept, reject, and hang up calls. Likewise, in another example, the play, forward and backward functions available for a CD player component of the car audio system 143 are operable to accept, reject, and hang up calls, respectively. In still another example, audio controls at the steering wheel may be used to enable hands-free access to the wireless communication functionality of the cellular phone 42. Examples of controls for content playback are now described. In one example, the preset radio-station buttons for a car radio component of the car audio system 143 are operable to access the various different content channels available in the cellular phone 142, and the seek buttons for the same car radio component are operable to skip forward or backward the content in a particular content channel, if the content includes the user's content or individual pieces of content that is controllable in such a manner. In another example, the play, forward, and backward functions available for a CD player in the audio system are operable to control the play, forward, and backward functions for accessing content in the portable content device, if the content includes the user's content or individual pieces of content that is controllable in such a manner. In still another example, for a CD changer in the audio system, the next disc, last disc, and disc selection functions are operable to control the next channel, last channel, and channel selection functions for accessing the content in the portable content device. In other examples, the aforementioned controls for content playback may be included in a user interface available on the wireless adaptor 173 as well, in the remote control 405, or activated by voice commands received through the microphone 407.
In one embodiment, the wireless adaptor 173 optionally includes an infra-red (IR), radio-frequency (RF), or IR and RF command module 460 to enable remote control of the wireless adaptor 173, the car audio system 143, and/or the cellular phone 142 via the remote control 405, and a speech command module 470 to enable control of the wireless adaptor 173, the car audio system 143, and/or the cellular phone 142 via voice command through a connected microphone 407, which may be integrated within the wireless adaptor 173 (not illustrated) or externally connected to the wireless adaptor 173 (as illustrated in
The IR/RF command module 460 and the speech command module 470 are operable in place of or in conjunction with one another. Furthermore, each is operable in place of or in conjunction with the application profile stack 173 and the network manager 430. When the user employs the remote control 405 to access the wireless communication functionality or control the content playback of the audio stream from the cellular phone 142 through the car audio system 143, the IR/RF control signals from the remote control 405 are received by the IR/RF command module 460 via an IR/RF receiver (not shown). The IR/RF command module provides conversion of the IR/RF control signals into corresponding electrical signals for forwarding to the command translation module 490, which then provides translation of such electrical signals to control the cellular phone 142, the car audio system 143, or both, or for sending out the signals as communication signals in a phone call.
In one embodiment, the wireless adaptor 173 further includes an echo cancellation module 465, which may be hardware and/or software implemented as understood in the art, to eliminate or attenuate sound echoes typically present in audio reception by the microphone 407 before they reach the speech commands module 470.
The speech command module 470 enables a user to give voice commands through the connected microphone 407 to control the wireless communication functionality of the cellular phone 142 or content playback of the audio stream from the cellular phone 142 through the car audio system 143. For example, the user may use voice commands for voice dialing of phone numbers through predefined voice tags, such as “dial 1” for one pre-programmed phone number associated with the predefined voice tag “1” and “dial 2” for another pre-programmed phone number associated with the predefined voice tag “2”. Such voice commands are converted into electrical signals by the speech command module 470 for forwarding to the command translation module 490, which then provides translation of such electrical signals to control the cellular phone 142, the car audio system 143, or both. As mentioned earlier, the speech command module 470 (in conjunction with the microphone 407) also allows a user to communicate during a phone call facilitated by the cellular phone 142. In an alternative embodiment, separate speech modules may be used to handle phone calls and voice commands. The use of the wireless adaptor 173 with the microphone 407 for making hands-free phone calls is less distracting and enhances the driver's safety in operation the vehicle as well.
The USB hub and host 510 enables a connection of a transceiver for a proximity wireless network. The transceiver includes the functionality of the application profiles stack 420 described earlier for the wireless adaptor 173 in
The USB storage manager 520 manages the retrieval and transfer of any content and content metadata stored on any USB storage key that is connected to the wireless adaptor 573 via the USB hub and host 510, to the car audio system 143 as streaming audio for stereo audio playback and metadata display through the later. Thus, the USB hub and host 510 acts a wired interface that allows a content storage device to be connected to the wireless adaptor 573 for content transfer. As with the transfer of content from the cellular phone 142, the content and content metadata from the USB storage key are decoded by the decoder 440 for playback and displayed, respectively, by the car audio system 143. In this embodiment, the wireless adaptor 573 may include a user interface located thereon, as noted earlier, that allows a user to control the playback (e.g., play, pause, skip, rewind, forward) of the content received by the USB hub and host 510.

At 640, the wireless adaptor 173 (or 573) receives content, such as audio content, from the content source via the wireless communication link as established wireless proximity network. At 650, the wireless adaptor 173 (or 573) also receives a request from the content player for a functional control of the content source, such as a selection of a content channel available in the content source. At 660, the wireless adaptor 173 (or 573) provides the content player with access to a functional control of the content source, as facilitated by the applications profiles stack 420. At 670, the wireless adaptor 173 (or 573) provides the content from the content source to the content player for content playback and control by the content player. The content playback also may include a display of content information at the content player.
Referring to the method illustrated in
At 740, the wireless adaptor 173 (or 573) receives a request from the content player, such as the car audio system 143, for one or more functional controls of the wireless communication device, such as the cellular phone 142. At 750, the wireless adaptor 173 (or 573) provides the content player with access to the one or more functional controls of the wireless communication device, as facilitated by the applications profiles stack 420.
At 760, the wireless adaptor 173 (or 573) also receives a command/control signal for a remote access of a wireless communication functionality of the cellular phone 142. The accessing signal may be initiated by the cellular phone 142 itself, a user's input from the remote control 405, the microphone 407, a user interface available on the wireless adaptor 173, or a user's input from the car audio system 143. For example, as mentioned earlier, the accessing signal may be initiated by the cellular phone 142 because of an incoming call, whereby the user is requested to accept or reject the call. As mentioned earlier, the user may be notified of the incoming call by an audible alert, such as an alert tone, and/or visual alert (such as an alert text) transmitted from the wireless adaptor 173 to the car audio system 143 via the I/O interface 450, as directed by the I/O manager based on information from the wireless proximity network manager 430 that is translated by the commands translation module 490. Furthermore, the visual alert may include metadata of the incoming call, such as caller ID. In another example, the accessing signal may be initiated by the user for an outgoing call via voice commands through the microphone 407, the remote control 405, an available user interface on the wireless adaptor 173, and/or the functional controls of the car audio system 143. In still another example, the accessing signal may be initiated by the user for accessing the phone list, last dialed number(s), and/or other call history information maintained in the cellular phone 142, for display at the car audio system 143. Again, the user may use voice commands through the microphone 407, the remote control 405, an available user interface on the wireless adaptor 173, and/or the functional controls of the car audio system 143 to access the pertinent phone information maintained in the cellular phone 142.
Referring back to
At 840, the wireless adaptor 173 (or 573) receives content, such as audio content, from the wireless communication device 173 (or 573) via the wireless communication link as established by the wireless communication network. At 850, the wireless adaptor 173 (or 573) also receives a request from the content player, such as the car audio system 143, for one or more functional controls of the wireless communication device, such as the cellular phone 142. At 860, the wireless adaptor 173 (or 573) provides the content player with access to the one or more functional controls of the wireless communication device, as facilitated by the applications profiles stack 420. At 870, the wireless adaptor 173 (or 573) routes the content from the wireless communication device to the content player, such as the car audio system 143, for content playback and control by the content player. The content playback also includes a display of content information at the content player.
At 880, the wireless adaptor 173 (or 573) further receives a command/control signal for a remote access of a wireless communication functionality of the cellular phone 142. As discussed earlier, the accessing signal may be initiated by the cellular phone 142 itself, a user's input from the remote control 405, the microphone 407, a user interface available on the wireless adaptor 173, or a user's input from the car audio system 143.
At 890, the wireless adaptor 173 (or 573) facilitates a remote access to the wireless communication functionality of the cellular phone 142, in response to the accessing signal received at 870 and in accordance with the one or more functional controls of the wireless communication device accessible by the content player at 860. For example, when there is an incoming call to the cellular phone 142, with an audible or visual alert sent to the car audio system 143, the wireless adaptor 173 (or 573) enables a user to accept or reject the call using the user interface on the car audio system 143, an available user interface on the wireless adaptor 173, the remote control 405, or voice commands through the microphone 407. In one embodiment, when an incoming call to the cellular phone 142 is received during content playback from the cellular phone 142 to the car audio system 143 (as facilitated at 870), the alert tone is transmitted to the car audio system 143 for output at a sufficiently high volume to interrupt the content playback (e.g., through attenuation or muting of the content playback volume relative to the alert tone) and ensure that it is heard over the car audio system 143 to warn the user of an incoming call. Likewise, sound received by the cellular phone 142 during a phone call is transmitted by the wireless adaptor 173 for output at a sufficiently high volume to interrupt the content playback and ensure that the phone call is heard over the car audio system 143. Alternatively, as directed by the wireless adaptor 173, the content playback may be paused during a phone call and continued again after the phone call. At this juncture, as discussed earlier, the wireless adaptor 173 is also operable to arbitrate access to the car audio system 143 for facilitating the wireless communication functionality or content playback. For example, if both the wireless communication functionality and content playback are facilitated through the same component, such as a CD changer, in the car audio system 143, content playback may be interrupted, as noted above, for the facilitation of the wireless communication functionality, such as a phone call. If the wireless communication functionality and content playback are facilitated through different components of the car audio system 143, such as a satellite radio and a CD changer, respectively, content playback may be interrupted with the wireless adaptor 173 automatically switching the car audio system 143 to CD changer mode to facilitate the wireless communication functionality. Likewise, even when there is no content playback and the car audio system 143 is initially set at a mode other than the CD changer, an initiated wireless communication functionality will trigger an automatic resetting of the car audio system 143 to the CD changer mode to handle the wireless communication functionality.
Alternative or in addition to the alert tone, the wireless adaptor 173 may generate an alert text for display at the car audio system 143, wherein the alert text display may replace or be in addition to any current display of the content information. In another example, when the user initiates an outgoing call through the car audio system 143, user interface on the wireless adaptor 173, the remote control 405, or the microphone 407, the wireless adaptor 173 directs the cellular phone 142 to make the call.
According to one embodiment, the wireless adaptors 173 and 573 in
According to the aforementioned embodiments and variations thereof that are within the scope of the present disclosure, the wireless adaptor 173 facilitates hands-free wireless communication functionality to users for convenience and safety. With the wireless adaptor 173, a user no longer needs to physically access a wireless communication device, such as a cellular phone, in order to access the phone functionality for communication purposes or content playback. The elimination of a requirement for physical access of the wireless communication device simplifies the tasks that the user must perform to use the device, enhances the user's experience with the device, and provides safety to the user during operation of a vehicle.
