Patent ID: 7457531

Claim:
A method of formatting audio and video information on a compact disc and reproducing the audio and video information using a portable device having an information processor coupled to an audio interface, a video interface, and a light emitting diode data acquisition sub-assembly for reading information from the compact disc, the video information having a video frame rate and the audio information having a sampled audio throughput for a single frame of video, the method comprising: combining a number of video pixels per sample, thereby generating a reduced sample-per-frame number; allocating a portion of available samples, determined from a comparison between the sampled audio throughput and the reduced sample-per-frame number, as a frame start portion and a frame end portion; formatting the frame staff portion and the frame end portion; recording the video information as non-compressed video on a first channel and the audio information on a second channel, the video and audio information being recorded as a modulated signal; acquiring the video and audio information by the light emitting diode data acquisition sub-assembly; processing the video and audio information in the information processor such that video information is provided to the video interface and audio information is provided to the audio interface; and reproducing the video and audio information; wherein the first and second channels are respective left and right audio channels associated with the compact disc, and the video and audio information are time-synchronized.
