Abstract

An optical disc recording and reproducing system having a single chip used for a video encoder and an A / V CODEC. The optical disc recording and reproducing system includes a recording medium recording in stream data digital audio data and video data encoded in certain compression formats; an A / V output part outputting audio and video signals corresponding to the stream data read out from the recording medium; an A / V CODEC converting the video data into a video signal of a certain format that the A / V output part can process; and an audio DAC converting the audio data into an audio signal that the A / V output part can process.

Description

technical field [0001] The present invention generally relates to an audio / video recording and reproduction system. More particularly, the present invention relates to an audio / video recording and reproducing system having a single chip serving as a video encoder and an audio / video (A / V) encoder-decoder (CODEC). Background technique [0002] A conventional optical disc recording and reproducing system separates a reproduced signal read from a recording medium into an audio signal and a video signal, and decodes the separated audio and video signals, respectively, according to a corresponding compression format. The recording medium may be a hard disk drive, a memory, a peripheral device, or an optical disc such as CD-R, CD-ROM, DVD, Blu-ray Disc (Blu-ray), Advanced Disc (AOD), or the like. [0003] In order to display the decoded reproduced signal on a display device (not shown) such as a television, a conventional optical disc recording and reprodu...
