HD-SDI H.264 Video Encoder for miniPCI express

The nanoH264-HD is an intelligent high definition video recording solution that accepts a HD-SDI input at up to 1080p30 and encodes it to the H.264 video encoding standard. In addition to capturing video and stereo audio data the nanoH264-HD supports extraction of KLV (MISB 0605.3 compliant) embedded data contained within the HD-SDI signal.


  • 1x HD-SDI input up to 1080p30
  • Real-time HD H.264 encode at 1080p30
  • Stereo audio capture from HD-SDI
  • KLV Metadata capture from HD-SDI
  • Super Low Power operation (less than 4W)
  • Very small footprint miniPCI-express form factor


  • Solid-State Digital Video Recorder
  • Vehicle-based Video Codec
  • Crime Scene Recording
  • Remote Video Surveillance
  • Traffic Monitoring and Control


The nanoH264-HD is supported by comprehensive SDKs that minimize development risk and shorten time-to-market for applications in video streaming, recording, or routing. The SDKs are available for popular operating systems such as Windows and Linux.
