Hi all, I've got to sync some byte wise data to a video frame, and I was thinking of using one of those sync seperator chips and at the right time, blank the analog video info and bit bang a byte of data using just black and white levels. At the other end, the video info is fed to a video card in a PC which will be analyzing each frame to detect movement etc. I imagine it can also extract the digital data as well. Does this sound feasable? -- Best regards Tony mICros http://www.bubblesoftonline.com mailto:sales@bubblesoftonline.com -- http://www.piclist.com#nomail Going offline?
