Product Details

The DTS 5.1 Decoder delivery from ADI has been highly optimized to run on the Analog Devices’ SHARC processor family. The DTS 5.1 Decoder is capable of decoding standard 5.1 DTS bit streams from a DVD-Video disc and the core DTS audio from a BluRay disc. Bitrates up to 1.5mb/s are supported. In addition to outputting the full 5.1 decoded surround sound, the decoder is capable of down-mixing to 2.1/3.1 and 4.1 configurations.


The ADI DTS 5.1 Decoder contains a standard C-callable ‘push’ API. The module has no dependencies on processor peripherals or registers, adding greater system flexibility and ease of use.
