A High-Rate Buried-Data Channel for Audio CD

Subtractive buried data is a new proposal for conveying a high-data-rate data channel (with up to 350 kbit/s or more) compatibility within the data stream of an audio CD without significant impairment of existing CD performance. This proposal uses pseudorandomized data as noise-shaped dither for the conventional audio. The new data channel may be used for high-quality data-reduced related audio channels, or even for data-compressed video or computer data, while retaining compatibility with existing audio CD players.
