I'm currently working on a networked security camera system, and am adapting it to work with PCs with DC10+ cards in them (previously we used NetWinders, but they have stopped selling rack mount NetWinders with video capture inputs). Currently we capture in uncompressed mode, draw a caption (name of camera and time/date) on the image, then compress it in software using libjpeg. I'd like to be able to use the ZR36060 to do the JPEG compression, but the captions are an essential feature for us. I was wondering if anyone has any idea how we could both draw the captions on the image and use the hardware JPEG compression. One possibility I was wondering about was whether it might be possible to loop the internal video output back to the internal video input, send the captions to the video output, and use the overlay features of the 7110A to superimpose the captions on the captured image? Also, I don't know a great deal about the JPEG format, but it seems like it might be possible to hack a JPEG file by changing the height field and adding some more lines (containing the captions) to the bottom of the image (or alternatively the top of the image). Does this sound feasible? -- --------------- Linux- the choice of a GNU generation. -------------- : Alex Holden (M1CJD)- Caver, Programmer, Land Rover nut, Radio Ham : -------------------- http://www.linuxhacker.org/ --------------------
