Backward Compatible Enhancement of DTS Multi-Channel Audio Coding That Delivers 96-kHz/24-Bit Audio Quality
The DTS core-plus extension multichannel audio coding methodology permits established audio coding systems to operate at higher bit rates and/or higher sampling frequencies while remaining compatible with first-generation decoders (legacy decoders). While popular algorithms such as DTS Coherent Acoustics, Dolby AC-3 and MPEG II can all benefit from our process, the paper describes in detail its specific application to the DTS subband ADPCM coding algorithm. A compatible bitstream is made up of -core- data, representing 48-kHz encoded audio signals; and -extension- data, representing differential audio data and/or higher frequency components. Existing core-only decoders make use of the core data to reproduce 48-kHz sampled audio. New 96-kHz decoders make use of both core and extension data to reproduce 96-kHz audio. The paper also describes the efficient real-time implementations of the 5.1-channel, core+extension decoder on a single SHARC 21065L 32-bit floating-point processor and the encoder on a Pentium III processor.:
