Embodiments of the invention relate to wireless communications. More particularly, embodiments of the invention relate to mixing of audio signals transmitted by a wireless communication device, for example, a cellular telephone.
Using current wireless communications devices (e.g., cellular telephones and other cellular-enabled devices) and protocols users can communicate using traditional voice communication protocols and techniques. Current wireless communications devices and protocols also provide the ability to transmit and receive data files. However, in some situations, wireless users may desire additional functionality, for example, the ability to mix media content to transmit via the wireless communications device. Current wireless communications devices and protocols do not support this functionality.
Embodiments of the invention are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings in which like reference numerals refer to similar elements.
In the following description, numerous specific details are set forth. However, embodiments of the invention may be practiced without these specific details. In other instances, well-known circuits, structures and techniques have not been shown in detail in order not to obscure the understanding of this description.
Wireless communications device 110 may be any type of wireless communications device known in the art. For example, wireless communications device 110 may be a cellular telephone. Wireless communications device 110 can communicate using any wireless protocol known in the art. Wireless communications device 110 may be configured to communicate with wireless communications tower 120 that may also communicate with other wireless communications devices (not shown in
Examples of wireless communications protocols that can be used with wireless communications device 110 may include, for example, a Time Division, Multiple Access (TDMA) protocols, a Global System for Mobile Communications (GSM) protocols, a Code Division, Multiple Access (CDMA) protocols, or any other type of wireless communications protocol. Wireless communications device 110 can be any type of wireless device that allows a user to communicate with a remote device, which may include, for example, a cellular telephone, a cellular-enabled personal digital assistant (PDA), a cellular-enabled vehicle, other cellular-enabled devices or other radio frequency, microwave, or infrared communications devices, etc.
In one embodiment, wireless communications tower 120 may be coupled with network 130 over a wired and/or a wireless communications link. Communication between wireless communications tower 120 and remote device 140 over network 130 may be accomplished in any manner known in the art. Wireless communications tower 120 is intended to represent any type of base station or repeater known in the art and is not required to be a tower.
In one embodiment, a user engaged in voice communications using wireless communications device 110 (e.g., a cellular telephone, or other cellular-enabled device) may, for example, wish to share an audio file (e.g., music, previously recorded spoken words, recordings of events) or other type of file with remote device 140. Using previous technology and protocols, the sharing of the audio file would be independent of the channel used to carry the voice communications. That is, the audio file could not be mixed with the voice communications signal in a manner that would provide good sound quality. In one embodiment, wireless communications device 110 may receive the audio file from electronic device 100. In an alternate embodiment, wireless communications device 110 may store the audio file that has been received from electronic device 100.
As an example use of the audio mixing, a user of a cellular telephone (an example of wireless communications device 110) may be engaged in a conversation with a party using a remote telephone (an example of remote device 140) using network 130 using a cellular telephone protocol (e.g., GSM). During the conversation, the user of the cellular telephone may wish to share an audio file with the remote party. The user of the cellular telephone may cause a laptop computer system (an example of electronic device 100) to transmit the audio file to the cellular telephone using, for example, Bluetooth communications protocols.
The cellular telephone can mix the received audio file (or a portion thereof) with the voice of the user as detected by the microphone of the cellular telephone, which allows the user to provide narration of the audio file as the audio file is being transmitted to the remote party. Other wireless communications devices, electronic devices and/or communications protocols can also be supported. Bluetooth protocols are described in “Specification of the Bluetooth System: Core, Version 1.1,” published Feb. 22, 2001 by the Bluetooth Special Interest Group, Inc. Associated as well as previous or subsequent versions of the Bluetooth standard may also be supported.
In one embodiment, a user of a wireless communications device (e.g., a cellular telephone) may initiate a communications session using a first wireless protocol, 210. This may be accomplished, for example, by a user of a cellular telephone placing a call to a receiving party using any type of cellular communications protocol known in the art, for example, GSM or TDMA. Other wireless communications devices and/or communications protocols can also be used.
The wireless communication device may receive data from an external source using, for example, a second wireless protocol, 220. Alternatively, the data may be received via a wired connection, for example, via a “dongle.” The data received from the external source may be, for example, an audio file, a video file or a text file, or any combination thereof. In one embodiment, the second wireless protocol may be a protocol that is not used for cellular communications. For example, the second wireless protocol may be a wireless local area network protocol (e.g., IEEE 802.11b or 802.11g) or the second wireless protocol may be a wireless personal area network protocol (e.g., Bluetooth). Any wireless protocol can be used. Also, any transmission technique including, for example, radio frequency, infrared, satellite, may be used.
IEEE 802.11b corresponds to IEEE Std. 802.11b-1999 entitled “Local and Metropolitan Area Networks, Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications: Higher-Speed Physical Layer Extension in the 2.4 GHz Band,” approved Sep. 16, 1999 as well as related documents. IEEE 802.11g corresponds to IEEE Std. 802.11g-2003 entitled “Local and Metropolitan Area Networks, Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications, Amendment 4: Further Higher Rate Extension in the 2.4 GHz Band,” approved Jun. 27, 2003 as well as related documents.
The wireless communication device may receive the data in any manner from the external source. In one embodiment, the wireless communication device may receive a complete file from the external source before further action is taken with the data. In another embodiment, the wireless communication device may receive only a portion of a complete file prior to taking further action. For example, the wireless communication device may begin receiving a streamed audio file and may take action on the received data prior to receipt of the complete file.
In one embodiment, audio signals detected by a microphone of the wireless communication device may be mixed with the data received from the external source, 230. For example, words spoken by the user of the wireless communication device may be detected by a microphone in any manner known in the art and audio, video and/or text from the received data may be mixed prior to transmission. This allows, for example, the user of a cellular telephone to transmit an audio or video file while providing commentary.
In one embodiment, the mixing may be performed in approximately real-time with respect to receipt or playback of the received file to allow the user of the wireless communications device to provide narration and/or continue a conversation. In an alternate embodiment, the mixed data may be stored by the wireless communications device for later transmission. The wireless communication device may then transmit the mixed signals using the first communication protocol, 240.
