| 1997 | Invention patented by Jae-Hoon Heo on August 26th, 1997. Abstract: A disc for recording audio data of multi-channels while being reciprocally used with a device for reproducing a DVD-video disc. The device for reproducing a DVD audio disc includes a video attribute of a video title set including an extended audio data mode; a sub-picture attribute thereof including the extended audio data mode; video/sub-picture packs including an extended audio stream, the extended audio stream being having an extended audio stream header and frames, the extended audio stream header having a usage area for storing an audio coding mode, sampling frequency, quantization bit number, and usage data of extended audio data, and the usage area of the extended audio data indicating bit extension, bandwidth extension, and channel extension of the extended audio data, whereby the video/sub-picture packs are made as an audio pack for selectively recording the extended audio data when recording and the audio data can be reproduced by combining reproducing data of a basic audio pack with the extended audio pack when reproducing the data from the disc. |
