The Matrox 2-Channel Multi-I/O Card is a simultaneous, independent 2-channel input and output 3G/HD/SD card that can be installed in Mac Pro and Apple Xserve systems. This card brings a new level of channel density to Mac-based systems.
It is designed for good performance, flexibility, and scalability. It shares a memory-centric, asynchronous architecture that provides high-speed transfers of video, audio, and graphics data between I/O peripherals, co-processors, the CPU, and host memory. On-board DMA engines allow data transfers to occur without any intervention from the CPU. Dedicated on-board 10-bit hardware scalers off-load CPU or GPU processes.
The full range of broadcast-quality video / audio inputs and outputs are supported in NTSC and PAL as well as 480p, 720p, 1080p, and 1080i HD resolutions at all frame rates. It supports 4:3 and 16:9 aspect ratios.
