Hi
At my design the Analog video is converted to BT656 by TW9900. (Output: ITU-R 601 or ITU-R 656 compatible YCbCr(4:2:2))
The connection between TW9900 to DSP (TMS320DM8148CCYEA0) is comprised of CLK, D0-D7. (HS, VS also connected, DE, Field not)
The image we got is displayed only at top half frame, the lower side of the frame is grey, pls. see attached.
It seem the DSP display the 2 fields on top part of the display.
- I assume the DSP can work only with SAV, EAV. Does it require the timing signals? Which it require?
- What we need configure at the SW for proper display?
Pls. advise.
