1. Field
The present invention is related to wireless communication systems, and in particular to systems and methods of managing and monitoring wireless communication systems.
2. Background
Wireless communication systems are widely deployed to provide various types of voice communication and data services. A typical wireless communication system can provide multiple users access to one or more shared resources, such as network bandwidth.
Wireless communication systems oftentimes employ one or more base stations that provide a coverage area by providing broadcast bandwidth within the coverage area. A typical base station can transmit and receive data streams and voice signals to and from one or more client devices, such as mobile phones.
However, typically such base stations use valuable broadcast bandwidth to communicate content to client devices. Further, the use of services provided via such base stations is not adequately tracked and analyzed.
The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.
Described herein are systems and methods for tracking and analyzing access point usage. By way of example, an access point can include a router function as well as broadcast interfaces/connectivity and/or local wireless network interfaces/connectivity such as PAN (personal area network)/LAN (Local Area Network) interfaces/connectivity. Such an access point is sometimes referred to herein as a broadcast access point (BAP).
In addition, described herein are systems and methods that enable various entities or end-users to become on-site broadcasters of content using BAP. Certain embodiments optionally statically and/or dynamically generate customized content and media guides for groups of BAPs, specific BAPs, groups of users, and/or individual users. The customized content is optionally selected using the tracking and usage information and/or BAP location information.
An embodiment of a localized broadcasting system comprises a first broadcast access point, the first broadcast access point including a processor, a wide area broadcast network interface coupled to the processor, a wireless local area network interface and/or wireless personal area network interface coupled to the processor, and a usage logging module.

The disclosed aspects will hereinafter be described in conjunction with the appended drawings, provided to illustrate and not to limit the disclosed aspects, wherein like designations denote the elements.
Described herein are example systems and methods that enable various entities or end-users to become on-site broadcasters of content, including but not limited to customized broadcasting, using broadcast access points. Also described herein are example systems and methods for tracking and analyzing access point usage. As will be described below, certain embodiments utilize the access point usage information to select customized channels of content, which are optionally transmitted to client devices over a PAN/LAN network using one or more broadcast access points.
The present devices, apparatus, methods, computer-readable media and processors now will be described more fully hereinafter with reference to the accompanying drawings, in which aspects of various embodiments are shown. The devices, apparatus, methods, computer-readable media and processors, however, may be embodied in many different forms and should not be construed as limited to the aspects set forth herein.
Various embodiments are described herein in connection with a mobile device. A mobile device can also be called a system, subscriber unit, subscriber station, mobile station, mobile, remote station, remote terminal, access terminal, user terminal, terminal, wireless communication device, user agent, user device, or user equipment (UE). A mobile device can be a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device having wireless connection capability, a computing device, an entertainment device (e.g., a television) or other audio/visual (AV) device having wireless connection capability, or other processing device connected to a wireless modem. Moreover, various embodiments are described herein in connection with an access point. An access point can be utilized for communicating with and transferring data to and from mobile device(s).
Various modes of usage tracking will now be discussed with respect to access points, such as access points that act as routers. Optionally, an access point may be in the form of a broadcast access point (BAP) including one or more broadcast ports providing wide area broadcast connectivity and also including one or more PAN/LAN ports providing PAN/LAN connectivity. Optionally, the PAN/LAN port transmits content using a non-addressed transmission where client devices can “tune in to” an ongoing transmission of content.
By way of illustration, the wide area broadcast connectivity can be compatible with cellular phone standards (e.g., UMTS, CDMA2000, TD-CDMA/TD-SCDMA, EDGE, UWC, DECT, Mobile WiMAX, LTE, UMB, other 3G networks, 4G networks, etc.) and/or other broadcast standards, such as MediaFlo, other multicasting forward link only technologies (where the data transmission path is one-way, such as from a network to the receiving device), T-DMB (Digital Media Broadcasting), ISDB-T (Integrated Services Digital Broadcasting—Terrestrial), 1seg, DVB-H ((Digital Video Broadcasting-Handheld)), tdTV, CMMB, OMA BCAST, WiMax, 3GPP Multimedia Broadcast Multicast Service (3GPP MBMS), etc.), and/or non-standard protocols and technologies.
By way of further example, the personal/local area network connectivity can be compatible with a variety of personal/local area network protocols, such as one or more IEEE 802.11 variants, Bluetooth, UWB (UltraWide Band), NFC, ZigBee, HiperLAN/2, etc. It is to be appreciated that the aforementioned listings of technologies and standards are provided as examples, and other past, current, or future, technologies (whether part of a standard or not), and standards can be used as well. The BAP may have an external antenna, to thereby provide an enhanced quality of service with respect to one or more parameters, such as coverage, error rate, latency, etc.
An example BAP can receive and transmit multimedia content. Multimedia content can include some or all of the following: real-time data (e.g., video, audio, tele-text, etc.), non-real-time data (e.g., pre-recorded clip casts which are downloaded for later viewing, pre-recorded audio clips, downloaded for later listening), and/or IP datacasts.
In a particular example embodiment, a wireless BAP is configured to distribute multimedia broadcasting content, such as television and/or radio audio channels (e.g., via MediaFlo, DMB, etc.), received from a broadcast transmitter, content from a local or remote mass storage device, or other source, by transmitting the content to multiple devices via PAN/LAN connectivity. Thus, even when devices, such as mobile phones or other client devices, do not have WAN (broadcasting) connectivity (e.g., as a result of poor reception or other absence of a WAN broadcast interface), nonetheless multiple devices can substantially simultaneously receive different (or the same) multimedia broadcast content via the same access point (e.g., a BAP).
Further, when a client device is connected to the BAP (e.g., to receive television channel or other content) using a short range radio link rather than via the broadcast link, the device power consumption will typically be reduced. The reduction of device power consumption is particularly beneficial for mobile devices having limited battery life.
Examples of devices with which an example access point communicates can include, but are not limited to cell phones, personal digital assistants, other handheld and/or mobile devices, automobile-installed devices (e.g., navigation systems, televisions, radios, etc.), entertainment devices (e.g., televisions), gaming consoles, etc. As noted above, the client devices may optionally include both broadcast WAN connectivity and PAN/LAN connectivity.
An example embodiment of a BAP includes a single tuner (e.g., a mobile television tuner) to support multiple channel acquisition. Optionally, the BAP may have multiple tuners (e.g., mobile television tuners) to support a higher number of channel acquisition. Optionally, rather than (or in addition to) using multiple tuners to access multiple channels, multiple multimedia broadcast services (e.g., multiple television channels) can be accessed via logical channels, such as multicast logical channels (MLCs), which are decoded by the BAP receiver.
The BAP may receive a media presentation guide (MPG) from a remote system via a broadcast port. The MPG may include a listing of available content channels (e.g., television channels, or other channels of available of content, such as movie channels, sports channels, music video channels, real time videos, other entertainment/news/educational channels, etc., where the content may be available on an on-demand basis, on a scheduled basis, and/or a hybrid of on-demand and scheduled content as discussed below) and optionally a broadcast schedule of shows including content program timing. Optionally, a single MPG can list content aggregated from multiple sources (e.g., broadcast television, Internet sites, local storage, remote servers, etc.). The BAP may transmit the media presentation guide a user client device. In addition, the BAP may transmit subscription information to the user device via a PAN/LAN port, providing some or all of the following: a listing of the services (e.g., channels or channel packages, such as a sports package, a movie package, a game package, a financial news service package, etc.) the user is currently subscribed to, the cost of the services (e.g., a monthly subscription fee), and additional services the user may subscribe to. Optionally, the BAP is configured to receive subscription requests from user devices, and process or forward for processing such subscription requests (e.g., to a broadcast service provider system, a BAP service provider system, or other system). Once a subscription request is processed and approved, the BAP may be used to provide the subscription service via a PAN/LAN port.
A BAP may be owned by (e.g., via outright ownership or via a license/lease from an outright owner), provided by, operated and/or maintained by a BAP service provider (BSP). The BSP may be a different entity then the broadcast provider providing cellular broadcast service.
As noted above, certain embodiments provide usage tracking with respect to broadcast services. The tracking may be with respect to the use of an access point to provide services to client devices and/or the tracking may be with respect to client devices, such as an “end-user” mobile device's service usage. The tracking may be performed using a client application resident and executing on a client device and/or using a logging application resident and executing on a BAP. For example, if MediaFlo is being utilized, a MediaFlo client may perform event logging.
In an example embodiment, one or more selected devices log user interactions with associated mobile television applications. Examples of such logged interactions may include some or all of the following events and/or other events:
The collected usage data is communicated to and stored in memory accessible by a networked computer system, such as that associated with a broadcast service provider, a BAP service provider, and/or other entity. For example, the networked computer system optionally may be an operations system that provides some or all of the following: billing functions, content management services, receipt and storage of content from content providers, distribution of content and program media guide presentation information to user devices (optionally via an access point), user-service subscription management, delivery of access and encryption keys, etc. The collected usage data is accessed and used (e.g., by a computer program and/or a human) to perform some or all of the following and/or other tasks:
etc.
The logging notification may be transmitted to the client device(s) via a broadcast network and/or via a PAN/LAN. The client devices may include different types of devices (e.g., some may be dedicated wireless televisions and some may be phones including a television function) or may be of the same type.
This logging notification can provide some or all of the following information/instructions:
The foregoing identifications may in the form of a code, encrypted or otherwise.
Optionally, some or all of the usage tracking logging instructions may be preprogrammed into the client device. Optionally, a logging notification message may be used to update or override such preprogrammed logging instructions.
At state 2, the selected client device(s) begin logging usage tracking events/data as instructed and stores the logged data in client device memory.
At state 3, the client device uploads the usage tracking data to the broadcast service provider system in response to a request from the broadcast service provider system or in response to a reporting trigger.
Depending on which business entity (either broadcast service provider or BAP service provider) manages and maintains the usage tracking data, usage tracking service modes can be classified into the following categories: (1) broadcast service provider managed usage tracking service and (2) BAP service provider managed usage tracking service for BAPs. Other categories can be used as well. Further, a broadcast service provider may also be a BAP service provider.
With respect to a broadcast service provider managed usage tracking service, the broadcast service provider manages and/or owns the usage tracking service data for BAPs and client devices. This category has includes some or all of the following sub-modes: (1) usage tracking service for devices, (2) usage tracking service for BAPs, and (3) usage tracking service for both devices and BAPs.
The BAP 306 further includes a broadcast interface 310 to communicate via a broadcast network. In addition, the BAP 306 includes a PAN and/or LAN interface 312, which can be used to communicate with client devices 322. Optionally, the BAP 306 can communicate with client devices 322 via the broadcast network in addition to or instead of the broadcast network. Optionally, the BAP 306 can communicate directly with client devices 322 without ever using the broadcast network to thereby reduce the burden on the broadcast network and broadcast network bandwidth. Optionally, the BAP 306 includes a wired (e.g., Ethernet) or wireless network interface 314 to a remote content storage system 318. Optionally, the BAP 306 can communicate with the storage system 318 using the broadcast network and/or the PAN/LAN. Other BAPs described herein optionally have the same or similar configuration as BAP 306, or optionally have different configurations.
At state 301, the broadcast service provider system 304 transmits a usage tracking notification to one or more BAPs 306, requesting the BAPs 306 to log various usage tracking data, including tracking data related to access of the BAP by client devices 322. The tracking notification can specify the data to be logged or can specify a logging profile to be used, where the logging profile has previously been stored on the BAP 306. The usage tracking data may include some or all of the following events and/or other events:
At state 300, the BAP 306 collects usage tracking information with respect to client devices 322 that are accessing or have accessed the BAP. The data collection can be performed with a specified start and end date or can be continuously performed until collection is manually halted. The data collection state 300 optionally can continue in parallel while other process states are taking place or can instead be paused or halted. The data collected can include some or all of the data discussed above and/or other data.
At state 302, the BAP 306 transmits the client device usage tracking logging data to the broadcast service provider system 304. For example, the usage tracking logging data can be transmitted via a broadcast network, a wired network, or other network to the broadcast service provider system 304.
Should there be privacy concerns with respect to usage tracking for client devices 322, optionally the BAP 306 is configured so that the BAP 306 will collect and/or retain only statistical information and will not forward any client specific usage tracking data. Optionally, a user interface is transmitted by the BAP, BSP system or otherwise to a user client device via which the user can opt out or into having the user's usage tracked. Optionally, to avoid disclosure of client specific usage tracking data, the BAP will delete any client specific usage tracking data from its internal memory once the statistical analysis on the data is performed so that it cannot later be accessed.
Optionally, in certain embodiments, the BAP 306 is configured to provide selected types of usage tracking data for a specific client device, but not in association with a client device or user identifier. Optionally, the BAP 306 is configured to provide selected types of usage tracking data for a specific client device in association with a client device or user identifier (e.g., for usage tracking information that does not raise significant privacy concerns).
In certain instances, a BAP 306 may be equipped with client functionality. For example, the BAP 306 may include both access point/router functionality that can be utilized by other client devices to access broadcast services, such as television channels, and end-user client device functionality, such as a user interface, a display, and a speaker to enable a user to select content channels, and view and hear content. For use cases where a BAP is equipped with client functionality, the broadcast service provider can request (1) usage tracking data only for the routing functionality, (2) usage tracking data for only client functionality or (3) usage tracking data for both routing and client functions.
At state 401, a broadcast service provider system 414 transmits a usage tracking notification to one or more BAPs 416. At state 402, the BAP 416 forwards the usage tracking notification from the broadcast service provider 414 to a client device 418 hosting the logging application. At state 403, the client device 418 transmits the logged usage tracking data to the BAP 416 in response to a request from the broadcast service provider system/BAP or in response to a reporting trigger. At state 404, the BAP 416 transmits the usage tracking data to the broadcast service provider system 414. Optionally, the BAP 416 preprocesses the usage tracking data prior to transmitting the data to the broadcast service provider system 414. For example, the BAP 416 may tabulate, aggregate, and/or statistically analyze usage data from a plurality of client devices prior to transmitting the tracking usage data to the broadcast service provider system 414.
At state 406, the broadcast service provider system 414 transmits a usage tracking notification to one or more BAPs 416, requesting the BAPs 416 to log various usage tracking. At state 408, the BAP 416 transmits the BAP usage tracking logging data to the broadcast service provider system 414. As discussed above, the logging data may be preprocessed by the BAP 416 and the privacy of the client devices can be maintained with respect to the usage tracking data.
A BAP service provider (BSP) may install one or more BAPs over a small, medium, or large geographic area. A BSP may have its own wired, broadcast, and/or PAN networks or infrastructure to support richer services to the client devices. The BSP can manage and own the usage tracking service data for its BAPs and for client devices provided by the BSP and/or for which the BSP provides services.
As with broadcast service provider managed usage tracking service, in the case of the BSP managed usage tracking service there may be several sub-modes, such as the following: (1) usage tracking service for devices, (2) usage tracking service for BAPs, and (3) usage tracking service for both devices and BAPs.
At state 602, the BAP transmits the client device usage tracking logging data to the BAP service provider system 604.
As similarly discussed above, should there be privacy concerns with respect to usage tracking for client devices optionally the BAP is configured so that the BAP will collect only statistical information and will not forward any client specific usage tracking data. Optionally, in certain embodiments, the BAP is configured to provide selected types of usage tracking data for a specific client device, but not in association with a client device or user identifier. Optionally, the BAP is configured to provide selected types of usage tracking data for a specific client device in association with a client device or user identifier (e.g., for usage tracking information that does not raise significant privacy concerns).
In certain instances, a BAP may be equipped with client functionality. For example, the BAP may include both access point/router functionality that can be utilized by other client devices to access broadcast services, such as television channels, and end-user client device functionality, such as a user interface, a display, and a speaker to enable a user to select content channels, and view and hear content. For use cases where a BAP is equipped with client functionality the BAP service provider can request (1) usage tracking data only for the routing functionality, (2) usage tracking data for only client functionality or (3) usage tracking data for both routing and client functions.
At state 701 a BAP service provider system 714 transmits a usage tracking notification to one or more BAPs 716. At state 702, the BAP 716 forwards the usage tracking notification from the BAP service provider 714 to a client device 718 hosting the logging application. At state 703, the client device 718 transmits the logged usage tracking data to the BAP 716 in response to a request from the BAP service provider system/BAP or in response to a reporting trigger. At state 704, the BAP 716 transmits the usage tracking data to the BAP service provider system 714. Optionally, the BAP 716 preprocesses the usage tracking data prior to transmitting the data to the BAP service provider system 714. For example, the BAP 716 may tabulate, aggregate, and/or statistically analyze usage data from a plurality of client devices prior to transmitting the tracking usage data to the BAP service provider system 714.
At state 706, the BAP service provider system 714 transmits a usage tracking notification to one or more BAPs 416, requesting the BAPs 416 to log various usage tracking data. At state 708, the BAP transmits the client device usage tracking logging data to the BAP service provider system 714. As discussed above, the logging data may be preprocessed by the BAP 718, and privacy of the client devices can be maintained with respect to the usage tracking data.
Of course, optionally for each of the above examples, usage tracking can be disabled.
Usage tracking service data collected by BAP and broadcast service providers can be shared, forwarded (optionally after performing preprocessing) and exchanged between the BSP(s) and broadcast service providers. For example, after the BAP service provider system collects usage tracking service data, filters or extracts data, the BSP service provider system optionally transmits such data to the broadcast service provider. Similarly, after the broadcast service provider system collects usage tracking service data, the broadcast service provider system filters or extracts data, and optionally transmits the data to the BAP service provider.
By way of example, the broadcast service provider may receive certain logged data from client devices related to movie channel viewing. The broadcast service provider can forward the log data to the BAP service provider. Optionally, the broadcast service provider system automatically filters out certain logged data prior to transmitting the logged data to the BAP service provider.
Referring to
In addition, another BAP service provider 808 similarly sends notification notices to all of the same BAPs 810 as does the BAP service provider 806. At state 803, the broadcast service provider system 806 transmits a usage tracking notification to one or more of the BAPs 810, requesting the BAPs 810 to log various usage tracking data, including tracking data related to access of the BAP by client devices 812. The tracking notification can specify the data to be logged or can specify a logging profile to be used, where the logging profile has previously been stored on the BAP 810. At state 804, the BAPs 810 transmit the client device usage tracking logging data to the broadcast service provider system 808. Thus, two different BAP service providers can provide their own logging instructions to, and can collect usage data from the same (or some of the same) BAPs.
Certain embodiments enable various entities or end-users to become on-site broadcasters of content (including customized channels and/or content) using one or more BAPs.
The owner of the BAP in this example (owner in this context can mean the actual owner, the BAP operator, and/or other entity having permissions to specify content sources which the BAP is to access and clients/terminals to which the BAP is authorized to broadcast content), sets up the BAP to subscribe to a package “A” 920 (as illustrated in
In certain optional embodiments, the BAP device owner can create and/or specify packages/channels of customized content which optionally includes content from one or more sources in addition to or instead of content from mobile TV services. Thus, a given channel or channels can include content aggregated from multiple diverse sources. Optionally, the BAP may access and/or transmit some or all of the customized content over PAN/LAN networks, thereby reducing or eliminating the need for mobile TV system bandwidth for such customized content. For example, referring to
To illustrate an example embodiment, a use scenario where a user creates a music channel will be described. A user interface is provided (e.g., via a Web page or otherwise) that can be accessed via a terminal (e.g., a general purpose computer, a phone, or otherwise) which enables the BAP owner or other authorized user to create a new channel/content package. The user interface optionally includes one or more of the following fields:
For example, optionally the user may specify a channel name/identifier. The user can further specify one or more content sources for the channel. For example, the user and/or BAP owner can specify that the content is to be accessed from one or more of the following sources and/or other sources:
Once the BAP is configured to receive content and broadcast one or more channels/programs, the BAP publishes its system information (e.g., its channel/program lineup) to client devices. Optionally, the client device is unaware of the original source of the content of each channel, that is, the client device is unaware from which source the BAP obtained the content (e.g., the client device does not know whether the content comes from a mobile TV broadcaster or elsewhere).
When a user, via a wireless client device, selects the channel from a mobile TV source, the BAP accesses/acquires the mobile TV channel and forwards the content by wirelessly transmitting the content to the client device (e.g., via a PAN/LAN).
If a user of the client device selects a customized channel, the BAP fetches the content from the source associated with the selected customized sources or tunes to the channel from the binding source. The BAP then forwards the content wirelessly to the client device.
Referring to
The content can then be accessed via one or more client devices 918 over a network 916 (e.g., a PAN or LAN network). The networks illustrated in
The BAP owner may create channels for various content, such as that included in Package B 922. The channels can be set up to carry a certain type of content (e.g., music, prerecorded movies, prerecorded still images, live still images, live movies, broadcast RF radio station, broadcast RF radio station, Internet radio, Internet television, etc.) and/or the content may be selected based in whole or in part on the geographic location or the intended use of the BAP. By way of illustration, the BAP may be intended to route content for the owner's personal use or the BAP may be intended to route content for business or civic purposes (e.g., to customers or potential customers of a business or public venue).
For example, where the BAP is being used for the BAP owner's personal use, the BAP owner can set up one or more of the following channels:
By way of example, when the BAP is utilized for a user's personal use, the BAP may be situated at a user's home, the user's car or other vehicle, or the user's office/place of business.
In addition to personal use in an owner's home/office/vehicle, the BAP may be utilized for commercial/civic purposes and/or may be located at various locales such as some or all of the following:
Optionally, a BAP installed at a particular venue/location is configured to provide one or more channels of content that are relevant/related to the business and/or venue/location.
In this example, broadcast zone I 1008 provides coverage for the reptile exhibit and broadcast zone II 1012 provides coverage for the African animal exhibit. Broadcast zone I 1008 offers customized content related to reptiles (e.g., documentaries on reptiles, including documentaries on reptiles being exhibited, sound tracks of reptiles, photographs of the reptiles on exhibit, streaming video of the reptiles on exhibit, encyclopedia entries on reptiles, etc.). Broadcast zone II 1012 offers content related to African animals. (e.g., documentaries on African animals, including on African animals being exhibited, sound tracks of African animals, photographs of the African animals on exhibit, encyclopedia entries on African animals, streaming video of the African animals on exhibit, etc.).
Multiple sources can be associated with a given customized or site specific channel (e.g., a remote networked content server and local mass storage). When multiple sources are associated with a given channel, an operator can set a priority configuration indicating which content has priority over others. The priority may be set via a user interface provided for display on an operator terminal. The priority may be set in terms of bandwidth, with respect to a type of client request received via the BAP, with respect to which client is making the request, or otherwise. For example, a first type of content (e.g., audio) that is more sensitive to interruptions may be allocated all the bandwidth that is needed, and the remaining bandwidth is divided (equally or otherwise) among other content. By way of further example, client requests for show times may be given priority over requests for an encyclopedia entry. By way of still further example, requests for content from users with a yearly pass may be given priority over requests from users who have purchased a one day pass.
Optionally, the system (e.g., via the BAP being accessed or via a remote computer system) will generate and/or dynamically modify/customize a media presentation guide, including channel and program listings, which will be downloaded to the appropriate client devices.
Content from external sources can be transmitted to a client upon a client request, or the content may be pushed to the client (e.g., streamed or otherwise transmitted to the client based on a predetermined schedule or in response to a given event) even in the absence of the client device request.
As discussed above, a BAP service provider can support not only diverse business entities (e.g., zoos, museums, stadiums, retail establishments, transportation companies) but also an individual end-user. For example, the BAP service provider may provide for display on a user terminal a user interface via which a user may configure one or more channels, specify the type of content to be provided via a given channel, specify schedules on which specific content is to be transmitted, specify areas/subjects of interest (e.g., interested in sports, a specific entertainer, local news, national news, movies, etc.) and/or specify a source of some or all of the content. The content may then be broadcast to the individual end user's terminal (e.g., phone or other device) via geographically distributed BAPs in accordance with the user specified configuration.
As previously discussed, content accessible via a BAP can be customized based on the locality of the BAP. Instead or in addition, channels can be customized and/or and channel content scheduled, based in whole or in part on the characteristics of a given BAP and/or based on user preferences/characteristics. For example, a BAP service provider (BSP) can create a customized channel and/or schedule content for the channel for a BAP and/or user clients based on their corresponding profiles and feedback.
Various techniques are optionally used to gather BAP/user profiles and/or feedback. An example technique utilizes the usage tracking process performed at the client devices and/or BAPs, as discussed above. In addition or instead, users may send explicit feedback information to the BSP.
For example, the usage tracking service described above may be utilized to obtain an aggregated preference of users of a given BAP. By way of illustration, the BAP can track and report to the BSP system how many devices have been accessing a given type of content (e.g., movies on movie channels) from a given source or source type (e.g., a mobile television service), over a period of time (e.g., the previous week). Optionally, the tracking service may also report to the BSP system the specific content (e.g., the name of the movies) that has been accessed and/or the movie genre (comedy, drama, action, horror, mystery, romance, etc.). If it appears from the tracking information that movies are being accessed with great frequency (e.g., where the number of movies/time period is greater than a specified threshold, the BSP (manually or automatically via the BSP system) may elect to create a customized movie channel for the BAP.
Optionally, the movies selected for the customized channels may be selected based on the types of movies that have previously been accessed via the BAP. The BSP may configure the customized channel via a user interface, wherein the authorized client devices can then access the new customized movie channel.
By way of further example, the BSP can create and define various channels for different purposes and targets, such as the following channel-types:
At state 1108, via an automated system and/or manually, some or all of the data is used to define one or more customized content channels. Optionally, the channels are dynamically customized in substantially real-time. Optionally, the system correspondingly dynamically generates a media presentation guide in substantially real time. At state 1110, the system receives via an interface location information (e.g., URL, pathnames, etc) identifying where content for the customized channel is to be accessed from, and/or the system determines such location information.
At state 1112, the system or another system or operator sets up one or more BAPs to receive and transmit such customized channels and content (e.g., by providing content location information, timing, criteria for determining which client devices can access which channels, and/or other settings). Optionally, a remote server, such as that associated with the BAP service provider, stores the content location information, timing, criteria for determining which client devices can access which channels, and the BAP routes requests from client devices received via the BAP's PAN/LAN interface, to the server. The server then accesses and transmits the requested content to the BAP, which can in turn relay the content to the client device. In such an embodiment, optionally the BAP does not store location information for each piece of content or content scheduling information. Further, in such an embodiment, the remote server may generate the media presentation guide, transmit the media presentation guide to the BAP, which then relays the guide to the client device.
At state 1206, the BAP transmits an appropriate, optionally customized media guide to the client device. The media guide may be generated by the BAP or the media guide may be accessed by the BAP from another system (e.g., a remote BAP service provider server). For example, the media guide may be in the form of the media presentation guide (MPG) described above, which provides a listing of available channels, including customized channels and optionally a broadcast schedule of shows including show timing. The media guide may be transmitted to the client device in response to a request from the client device, or the media guide may be pushed to the client device.
At state 1208, the BAP receives a request for content, which may be in the form of a channel request (e.g., a customized channel) or a request for specific content (e.g., a customized program) from the client device. At state 1210, the requested content is transmitted to the client device (e.g., as a file or streamed to the client device by the BAP). Optionally instead, the client device may tune into the customized content that is already being broadcast, rather then transmitting a request for content.
In an example embodiment, a BAP does not broadcast content until a request is received from a client device. When a first client device connects to the BAP, the BAP transmits a media guide to the first client device. The first client device user can then select a first content from the media guide. The first client device transmits a request for the first content to the BAP, which then accesses the requested first content (e.g., from local memory, a remote server, a broadcast, a video camera, etc.), and transmits a port to the first client device for the first content and transmits the first content via a PAN/LAN. The requesting first client device can then access the first content.
If a second client device then connects to the BAP while the selected first content is being transmitted to the first client device, the BAP optionally transmits a media guide to the second client device, wherein the media guide is configured to indicate that the first content is currently being transmitted and available to the second client device. If the second client device user selects the first content, the same port as was transmitted to the first client device is transmitted to the second client device. Then the second client device will access the first content at the same time as the first client device using the same port, without the BAP having to initiate a separate transmission of the first content to the second client device. Thus, optionally, content can be transmitted using a hybrid of on-demand and “scheduled” techniques, where the first content is initially provided to the first user in response to the first user request, but then other users can tune in to the ongoing transmission of the first content.
Optionally, instead, the BAP will initiate a new transmission of the first content to the second client device in response to the second client device user selection, where the first content will be played from the beginning.
Optionally, if transmission of the first content to the first client device has begun and is continuing, and a request for the same content is received from the second client device, the BAP automatically determines bandwidth and/or PAN/LAN transceiver availability. If there is sufficient bandwidth and/or PAN/LAN transceiver availability (e.g., equal to or greater than a specified threshold stored in memory or calculated by the BAP), the BAP will initiate a new transmission of the first content to the second client device, from the start of the first content. This enables the user of the second client device to watch the first content from the beginning. However, if the BAP determines that there is insufficient bandwidth and/or PAN/LAN transceiver availability (e.g., below a specified threshold stored in memory or calculated by the BAP), the BAP will not initiate a new transmission of the first content to the second client device. Instead, the second client device will access the first content already being transmitted at the same point as the first client device is currently accessing the first content.
In order to reduce unneeded transmission of content (e.g., to reduce power consumption and bandwidth utilization), the BAP may periodically ping client devices after transmission of content to the client devices has begun. If no response is received from any client device that had requested the content (e.g., indicating that the client devices are no longer within range of the BAP PAN/LAN or that the client devices have been turned off), then the BAP optionally will cease transmission of such content.
Thus, as described above, certain embodiments wirelessly provide common and/or customized content to user terminals in a cost effective manner without requiring an expensive transmitted deployment and without consuming wireless, cellular phone broadcast capacity and bandwidth. Further, certain embodiments include BAPs that provide a local broadcast area via PAN/LAN technologies, where the local broadcast area is much smaller in geographical size than that provided by many conventional approaches. Certain embodiments are scalable in size and support diverse use cases ranging from individual end-users, to very large venues.
