The Jazz Jakarta with the video input card is pretty similar to the Matrox Comet/Marvel II. They all use a Phillips SAA7110 NTSC/PAL/SECAM video decoder and Tseng Labs ET4000v33 video scaler/processor, and ET4000w32p video output. The main differences are that: o Jazz uses two cards one PCI card with everything except the video input and an additional card with the SAA7110 video input. There is some special ribbon cable bus between the two cards. (The Matrox has all of this on one card, the ET4000v33 is located on a bus from the ET4000w32p and the I2C bus is driven from two pins on the ET4000v33) o The Matrox cards have a RGB video input card for high-end cameras. Matrox proved to be less than cooperative for support and also both abovementioned cards have only 2MB RAM to share between video images and general X usage. XInside does support the Matrox cards quite well in there last beta release. Both the SAA7110 and RGB input works quite well and the image quality is better than that of an old Data Translation DT2853 frame grabber. For better programming support and dedicated video input there are new PCI cards from BitFlow and Imaging Technology. I'm testing a BitFlow card right now. It was up and running in a few days thanks to good support (and it is much easier to program than the Comet). This is currently used for testing with input from a 1024x1024 resolution greyscale camera. (The Raptor card costs $3500 and a Pulnix PN1001 camera ~$10000). Jonas
