The H264ULL-ENCODER is an ultra low latency, quad channel, H.264 encoder on a single PCI/104 form factor board. The H264ULL-ENCODER provides a powerful and flexible solution for capturing and compressing up to 4 analog video inputs at full size and at full frame rate to the H.264/MPEG-4 AVC (Part 10) standard.

The ultra low latency full frame rate encoding of four NTSC/ PAL analog video sources offered by the H264ULL-ENCODER can be combined with Advanced Micro Peripherals H264ULL- DECODER to produce an end-to-end ruggedized low latency video streaming solution.

The high performance H.264 video compression and efficient bus utilization allows the H264ULL-ENCODER to be hosted on a low power, fanless CPU, PCI/104 system.
