At http://www.etsi.org/ some specs for DTS streams can be freely downloaded. In the latest version (2002-12) there are even code samples and tables specified.
Not in the spec is how to code the raw samples into the DTS samples. However they tell exactly which algorithms are used:
Adaptive prediction
Lineair scalar quantization
Vector quantization (VQ)
Huffman code
Quadrature mirror filter (QMF)
With Google all these algorithms can be found on the web, including sample code. Hence, would it be possible to use these public and freely available algorithms and code snippets to create/decode a DTS stream? Thereby using the frame-structure as found in the ETSI spec?
Before I spend a lot of time on this I would like to hear some opinions. Please, feel free to give your opinion. I am specially interrested if someone has experience with the algorithms mentioned above.
