Patent ID: 8055116

Claim:
A method for providing an audio-only recording of a digital audio and video (A/V) stream, the method comprising: receiving the digital A/V stream, the received digital A/V stream including a multiplexed and compressed digital A/V stream; demultiplexing the received digital A/V stream into a demultiplexed video stream and a demultiplexed audio stream separate from one another; receiving an encoding format selection from a user; and in response to receiving an audio-only record command from the user while the digital A/V stream is being received, if the demultiplexed audio stream is of a same format as the encoding format selection from the user, storing the demultiplexed audio stream in a memory without further decoding and re-encoding of the demultiplexed audio stream, otherwise, (i) decoding the demultiplexed audio stream to produce a decoded audio stream, (ii) re-encoding the decoded audio stream based on the encoding format selection to produce a re-encoded audio stream, and (iii) storing the re-encoded audio stream in the memory, wherein the audio-only record command is received through an on-screen display (OSD) presented via a device on which a video portion of the digital A/V stream is being displayed.
