`
`What is also needed is a system and method for automatically answering and
`recording video calls in Which a television program or other broadcast
`entertainment program is automatically buffered to allow a user to
`subsequently view the program in its entirety.
`
`Allen J] e H(((0I&
`
`In certain embodiments, if the user accepts the request (or later interrupts the
`recording of a video message to communicate with the caller), the ITV system
`begins to buffer a television signal being currently displayed. When the video
`communication is terminated, the ITV system plays back the television program
`being buffered from the point in time at which the communication commenced.
`
`Allen J] e H((*/I&
`
`Later, when the communication is terminated, the television signal 404 being
`buffered may be played back from the point in time at which the communication
`commenced. Buffering may continue during playback, effectively time-shifting
`the television signal 404 for the period of the communication. As a result, the

`
`In regards to reception, an incoming (i.e., downstream) video conferencing
`signal is received by a receiver 750, decoded by a channel decoder 755,
`decrypted by a decryptor 760, and demutliplexed with proper relative timing
`among video, audio and other data components by a demultiplexer
`synchronizer 765. Video signals are decompressed by a video source decoder
`770 and output for display on a display device 602, which is typically the
`television 222. Audio signals are decompressed by an audio source decoder 775
`and output for playing on the speaker/microphone 2002, the speaker portion of
`which may be the speaker(s) of the television 222 Data files, such as electronic
`books, are stored in one or more files 777. Again, the order of processing can
`be different from that illustrated.
