8 Channel H.264 Video Codec for CompactPCI

The H264-cPCI8 is an eight channel H.264 codec for CompactPCI systems. The H.264-cPCI8 provides a powerful and flexible solution for capturing and compressing up to 8 analog video inputs at full size and at full frame rate to the H.264 / MPEG-4 AVC compression standard.

The H264-cPCI8 not only provides H.264 compression but can also simultaneously decompress and replay recordings from storage to display. This board 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 multiple H264-cPCI8 cards to be fitted in a CompactPCI for multi-channel video recording and streaming applications.


  • 8 channels analog SD composite video inputs
  • Real-time 8x H.264 full frame rate, full size (4QCIF) encode
  • H.264/MPEG-4 AVC (Part 10) encoder / decoder
  • Medium Latency encoder (down to 100ms)
  • Fast text overlay on recording for Time/Date stamp etc.
  • GPS for universal time-stamping (option)
  • Multiple H264-cPCI8 boards per system
  • 3U CompactPCI form factor
  • Drivers for Win-XP-E, Linux


The H264-cPCI8 is supported by comprehensive and well supported software development kits (SDKs) for video recording and video streaming. The SDKs are designed to significantly reduce development time in Windows and Linux environments and include support libraries, drivers and example applications to help developers fully utilize the H264-cPCI8 features in complex video compression / overlay applications.

The standard Video Recording SDK and sample applications are supplied free of charge with each board and includes the services of our technical support team. The Video Streaming SDK is available for a one-time fee and enables real time streaming of compressed video data over an IP network.
