Is there a complete or concise Primer somewhere (link) on video formats, especially including the DM6467T. I found a table one time on the wiki, but I can't find it again.
In particular, I have shell codec code derived from canny edge detection, that is receiving YUV420SP format. I want to efficiently convert it to RGB, but find that VLIB does not support any 420SP at all, much less converting it to RGB. So I'm trying to figure out if the DM6467T can be configured or otherwise efficiently coaxed into producing a format that VLIB can indeed turn into RGB.
Otherwise, I need to write my own [efficient?!] conversion from 420SP to RGB. To do this, I'd love a sample copy of a VLIB or other routine that does this, taking advantage of the very wide processing capability of the DSP.
In case it matters, my source video right now is 720P. In the future, it could be 1080P or simple SD NTSC (dunno notation for this, 480i ?). Also, note that in http://focus.ti.com/lit/ug/spruer9d/spruer9d.pdf there's not a single reference to the text "420" or "422", even though there's a figure 5 that looks semiplanar, but would be 422SP if anything, due to the memory sizes. In other words, this pdf is no help.
Thanks very much,
Helmut
