video geekery question
Mar. 16th, 2004 12:38 amI have a EPIA-V motherboard. It has a Video-In connector which I have a pinout for, a vague reference to a spec, and no other info. The spec is CCIR601, which any other reference I've looked at refers simply to pixel size or occasionally resolution, with no mention of such useful things as what the actual pins do, etc. The pinout for the connector, a simple 15+1-pin keyed header, is as follows (starting at pin 1, working up): GND, CVD0, CVD7, CVD4, CVD6, CVD5, CVHS, CVD2, CVD1, CVD3, CVVS, CVCLK, A_D30, [KEY], -GNT2, -REQ2. Now, I can guess at horizontal sync, vertical sync, clock, and ground. What the rest are I have no idea, but I'd really like to make use of this port if I can since it allows me to pump a digital video feed directly into the board. Anybody got clues, pointers, or that sort of thing?
