Hi, Does anyone know if S7 is backward compatible with the S-Video standard? (S7 is S-Video with 7 pins, while S-Video has 4 pins.) Can I plug an S-Video (4-pin) cable into the S7 Video output port? I want to feed the video signal from an S7 ouput port to a TV, using the normal S-Video-to-RCA-cable? I have noticed that S7 contains 4 outer pins and three inner pins. The four outer pin...

Hi, As I said it in another post we currently work on a card which includes a DSP TI TMS320DM642, a video decoder (SAA7118), SDRAM, etc.... Our aim is to capture a NTSC YUV video, save it and later compress it. Until now we've succeeded in configuring the registers of the video decoder; the output video data are as expected so this part has been validated. To capture these video data w...
