The H264-ULL-RS343 is an ultra low latency, dual channel, H.264 encoder for CompactPCI Serial systems. The H264-ULL-RS343 provides a powerful and flexible solution for capturing and compressing 2 Analog RGB RS-343 sources at up to 1080p HD resolution to the H.264/ MPEG-4 AVC (Part 10) standard.

The H264-ULL-RS343 is ideal for time-critical applications as it offers Ultra Low Latency encoding of below 40ms across the entire capture resolution range. The H264-ULL-RS343 supports dual H.264 encodes at resolutions up to 1080p30 or a single channel encode at 1080p60. The H.264 encoding can be flexibly configured to suit a range of bandwidth and storage requirements.

The ultra low latency feature of the H264-ULL-RS343 makes it ideal for real-time video I/P streaming and distribution of RS-343, VGA or other Analog RGB video.

The H264-ULL-RS343 is a standard 3U CompactPCI -Serial form factor module available with a comprehensive video recording SDK for Linux and Windows. An extended RTSP video streaming SDK is also available for applications requiring transmission of the captured data over IP links.
