So you think that Freescale conceals what the DCE really can do at this point in time when you can already purchase the hardware?

I don't understand. What you mean "conventional encoding and decoding applications"? Encoding/decoding means using a specific (set of) algorithm(s) to transform a bitstream into another bitstream under certain rules. In case of the DCE, algorithms mentioned specifically by Freescale have been implemented in hardware to accelerate the transformation. What's "conventional" about specific algorithms?

Huh? You mean that somebody should invent A/V codecs that use algorithms that the DCE implements, establish those new codecs as a standard and make the world use those codecs, so that subsequently the DCE could be used for decoding/encoding A/V data? Sounds like a plan ...not ;-) Thing is that the algorithms implemented by the DCE may not be suited for encoding of A/V data. Refer to:
As you can see, the first 3 are essentially just applications of LZ77
. All of them, i.e. LZ77, Huffman and Base64, are *lossless* encoding algorithms. Thus, I can only repeat that I can't see where A/V encoding or decoding could fit here.
