CD INCLUDING BOTH DATA IN REDBOOK FORMAT AND CODE IN YELLOWBOOK FORMAT TO AUTOMATICALLY CONVERT DATA

摘要

A method and apparatus (201) for recording and playing a CD (104) that includes data carried in Redbook format and executable code carried in Yellowbook format to convert that data is described. In one embodiment of the invention, a CD (104) includes a first part storing computer-executable code carried in Yellowbook-encoded format and a second part including data carried in Redbook-encoded format. The data carried in Redbook-encoded format was Redbook-encoded from currently unplayable data representing converted content, carried in Redbook-unencoded format. The converted content was converted from input content. The computer-executable code, when executed by a computer, causes the computer to optically read the data carried in Redbook-encoded format, Redbook-decode the data carried in Redbook-encoded format into the currently unplayable data, and convert the currently unplayable data into currently playable reconstructed data approximately representing the input content. The conversion is accomplished through at least a decompression routine (107) expressed in the computer-executable code. The input content may be input video content, input audio content sampled at a higher sampling frequency than a sampling frequency allowed by Redbook-encoded format, input audio content sampled with a larger word length than a word length allowed by Redbook-encoded format, etc.
