4 channel, full frame rate, H.264 encoder / decoder for PC/104-Plus

The VCODEC-H264-D4 is a 4 channel, full frame rate H.264 Codec for the PC/104-plus bus. The VCODEC-H264-D4 provides a powerful solution for capturing and compressing analog video inputs to the H.264 standard. The VCODEC-H264-D4 not only provides H.264 compression but can also simultaneously decompress and replay recordings from storage to display.

The VCODEC-H264-D4 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 reduced bus utilization allows up to four VCODEC-H264-D4 cards to be fitted in a PC/104-plus system.


  • Quad speed H.264 (MPEG-4 Part 10 AVC) video codec
  • Up to 4 x 4CIF (704×576) size encoding at full frame rate (NTSC/PAL video signals)
  • H.264 decode playback
  • Composite video or s-video outputs for preview or playback
  • High speed text overlay (for recording path)
  • High speed bit mapped graphics overlay with multi-level alpha blending (for analog preview output)
  • Automatic detection of motion
  • G.723 audio codec for each input channel with single audio playback channel
  • Real-time video preview to system VGA or NTSC/PAL output
  • Up to 4 VCODEC-H264-D4 cards per system
  • Drivers for Windows and Linux
  • PC/104-Plus 3.3v Add-in module
  • Operating temperature: -40°C to +85°C


The VCODEC-H264-D4 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 VCODEC-H264-D4 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.
