Set-top box 130 is coupled to output device 132 via communication link 142. Communication link 142 may include a video channel for communicating video information from set-top box 130 to output device 132 and an audio channel for communicating audio information from set-top box 130 to output device 132.
Fig. 3 is a simplified block diagram of an exemplary set-top box 130 according to an embodiment of the present invention. Set-top box 130 typically includes at least one processor 162 which communicates with a number of peripheral devices via a bus subsystem 160. These peripheral devices may include a storage subsystem 164, comprising a memory subsystem 166 and a file storage subsystem 172, a video subsystem 178, an audio subsystem 176, a distribution center interface subsystem 174, and a control device interface subsystem 180.
Distribution interface subsystem 174 provides an interface for receiving multimedia content information from distribution center 106. The multimedia content is then processed and forwarded to display device 136 and/or to audio output device 134 for output to the user. Control device interface subsystem 180 detects signals received from control device 138 and provides instructions/information encapsulated in the signals to processor 162 for further processing.
Audio subsystem 176 is responsible for processing audio content received from distribution center 106, and transmitting the processed audio signals to audio output device 134 for output to the user. Likewise, video subsystem 178 is responsible for processing video content received from distribution center 106, and transmitting the processed video signals to display device 136 for output to the user.
Storage subsystem 164 stores the basic programming modules and data constructs that provide the functionality of the various systems embodying the present invention. For example, databases and modules implementing the functionality of the audio source button may be stored in storage subsystem 164. These software modules are generally executed by processor 162. Storage subsystem 164 may comprise memory subsystem 166 and file storage subsystem 172.
Memory subsystem 166 typically includes a number of memories including a main random access memory (RAM) 170 for storage of instructions and data during program execution and a read only memory (ROM) 168 in which fixed instructions are stored. File storage subsystem 172 provides persistent (non- volatile) storage for program and data files, and may include a hard disk drive, a floppy disk drive along with associated removable media, a Compact Digital Read Only Memory (CD- ROM) drive, an optical drive, or removable media cartridges. The databases and modules implementing the functionality of the present invention may also be stored by file storage subsystem 172.
Bus subsystem 160 provides a mechanism for letting the various components and subsystems of set-top box 130 communicate with each other as intended. Although bus subsystem 160 is shown schematically as a single bus, alternate embodiments of the bus subsystem may utilize multiple buses. Further, in alternate embodiments of the present invention, the various components of set-top box 130 may be directly coupled to processor 162.
Due to the ever-changing nature of processing units 130, the description of set-top box 130 depicted in Fig. 3 is intended only as a specific example for purposes of illustrating the preferred embodiment of the present invention. Many other configurations of processing unit 130 are possible having more or less components than the processing unit 130 depicted in Fig. 3.
Fig. 5 depicts a simplified flowchart 190 depicting processing performed according to an embodiment of the present invention. According to the present invention, a control, for example, button 152 depicted in Fig. 4, is provided on control device 138 for changing the source of audio signals played by audio output device 134. For example, by clicking on audio source button 152 situated on control device 138 depicted in Fig. 4, the user can change the source of the audio signals communicated to audio output device 134. As previously stated, several audio sources may be embedded in the Web content and television content received by set-top box 130 from distribution center 106. For example, audio sources embedded in the Web content may include Uniform Resource Locators (URLs) linking to audio clips. Audio clips may also be associated with web pages received from distribution center 106. Further, applications such as "chat" may also provide sources of audio information. Further, television content may have its own audio source. In general, an audio source may be any object, element, or content embedded in the Web content or television content received from distribution center 106 which has audio information associated with it. Processing depicted in Fig. 5 is initiated when set-top box 130 receives a signal from control device 138 indicating that the user has selected (or clicked) the control, for example, audio source button 152, on control device 138 which controls the source of audio signals played by audio output device 134 (step 192). For purposes of this application, the control will be referred to as the audio source button. As discussed above, signals from control device 138 are received by control device interface 180 via communication link 140. The instructions/information contained in the signal is then made available to processor 162 for further processing. Software modules executed by processor 162 then determine an audio source, from the Web content and television content, whose signals are to be communicated to audio output device 134 for output to the user (step 194). The audio signals from the audio source determined in step 194 are then transmitted to audio output device 134 for output to the user (step 196).
Several different techniques may be used by the present invention to determine the audio source in step 194. According to one technique, the present invention may cycle through the available audio sources when the user clicks on audio source button 152. Fig. 6 depicts a simplified flowchart 200 showing processing performed by set-top box 130 for cycling through a list of available audio sources according to an embodiment of the present invention. As shown in Fig. 6, upon receiving a signal (hereinafter referred to as the "audio source button signal") from control device 138 indicating that the user has selected audio source button 152, set-top box 130 determines all the audio sources embedded in the Web content and/or the television content received from distribution center 106 (step 202). The audio sources may be organized in an ordered list, to allow set-top box 130 to more easily select the next audio source to be output to the user. Set-top box 130 then determines the audio source whose signals are presently being played by audio output device 134, or alternatively, if no audio signal is currently being played, set-top box 130 determines the audio source which was last played (step 204). Set-top box 130 then determines the "next" audio source, from the ordered list of audio sources determined in step 201, whose audio signals are to be communicated to audio output device 134 to be output to the user (step 206). Audio signals associated with the "next" audio source are then transmitted to audio output device 134 for output to the user (step 208). According to the embodiment of the present invention depicted in Fig. 6, every time a user clicks or selects audio source button 152, audio signals associated with a "next" audio source are communicated to audio output device 134 to be output to the user. In this manner, the present invention allows the user to cycle through all the available audio sources by repeatedly clicking on audio source button 152.
According to a more elaborate technique, the present invention may allow the user to specifically select an audio source whose audio signals are to be output to the user via audio output device 134. Fig. 7 depicts a simplified flowchart 220 showing processing performed by set-top box 130 according to this embodiment of the present invention. As shown in Fig. 7, upon receiving the audio source button signal, set-top box 130 determines all the audio sources embedded in the Web content and/or the television content received from distribution center 106 (step 220). Set-top box 130 then generates a user interface which displays the available audio sources to the user (step 222). The user interface is generally presented to the user via display device 136. Various types of user interfaces may be provided allowing the user to select a particular audio source. The user may then use the various buttons located on remote control device 138 to select a particular audio source whose signals are to be output via audio output device 134 (step 224). Upon receiving the user's selection, set-top box 130 then transmits audio signals associated with the user-selected audio source to audio output device 134 for output to the user (step 226). In this manner, according to the embodiment of the present invention depicted in Fig. 7, the user may specifically indicate an audio source whose signals are to be output.
As described above, the present invention allows the user to control the audio signals which are output to the user via audio output device 134. It should be apparent that various other techniques, in addition to those described in Figs. 6 and 7, may be used by the present invention to determine an audio source to be played back to the user.
Although specific embodiments of the invention have been described, various modifications, alterations, alternative constructions, and equivalents are also encompassed within the scope of the invention. The described invention is not restricted to operation within certain specific data processing environments, but is free to operate within a plurality of data processing environments. Additionally, although the present invention has been described using a particular series of transactions and steps, it should be apparent to those skilled in the art that the scope of the present invention is not limited to the described series of transactions and steps. Further, while the present invention has been described using a particular combination of hardware and software, it should be recognized that other combinations of hardware and software are also within the scope of the present invention. The present invention may be implemented only in hardware or only in software or using combinations thereof.
The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense. It will, however, be evident that additions, subtractions, deletions, and other modifications and changes may be made thereunto without departing from the broader spirit and scope of the invention as set forth in the claims.
