The VCODEC-H264-D4CX is a 4-channel H.264 (MPEG-4 Part 10 AVC) codec on a single PC/104-Plus form factor module. The VCODEC-H264-D4X provides a powerful and flexible solution for capturing and compressing up to 4 analog video inputs at full size and frame rate to the H.264 digital video standard.

The VCODEC-H264-D4X not only provides H.264 compression but can also simultaneously decompress and replay recordings from storage to display.

The VCODEC-H264-D4X allows high quality real-time video and audio capture and compression from NTSC/PAL video sources to disk and simultaneously provides an additional path for uncompressed video for on-screen preview or optional downstream video analytics. The high performance H.264 video data compression and efficient bus utilization allow up to four VCODEC-H264-D4 cards to be fitted in a PC/104-Plus system with spare band-width for other collaborating peripherals.
