Hi all, I need some help about video decompression. I am not sure to hav understood well the various steps. For example, I have a video (type MPEG4) in RAM on a board TMS320C6416 an I wish to display it on a TV. What are the various things to be made Decompression, DAC, sending towards the TV, ... If somebody knows where I can found more information about the steps, an about the formats between the steps (MPEG4, YCbCr, 4:2:0, ITU-656, ...) Thank you in advance Damien

Since you mention TI - there are quite a few app notes and tutorials on TI's website.
Generally speaking it would look like this:
- decode MPEG into a frame of YUV
- send YUV frame to a video DAC
If you're using TI's DSP BIOS a lot of the ugly parts are handled for you.

^^^^^ Hopefully you mean 4:2:2 ?

Thank you for these elements of answer. In fact, I have already found the app notes on TI's website, but I did no find examples of codes. I do not understand wher I must begin...
