The HDCorder-SDI is an intelligent high definition video recording solution that accepts a HD-SDI input at up to 1080p60 and encodes it to the H.264 video encoding standard. The CompactPCI-Serial board solution is ideal for demanding applications in Military, Communications, Transportation, mining and Energy industries.

In addition to capturing video and stereo audio data the HDCorder-SDI supports extraction of KLV (MISB 0605.3 compliant) embedded data contained within the HD-SDI signal. The video, audio and metadata are synchronized and transferred to the host system over the CompactPCI -Serial bus. An SDI monitor output is provided

The HDCorder-SDI also features optional on-board redundant storage to compliment the host system storage and improve data integrity. This on-board cache acts as a rolling buffer, storing the most recently recorded data. This storage redundancy ensures no mission data is lost even when starved of host CPU attention in heavily loaded system configurations.

The HDCorder-SDI is a standard 3U CompactPCI -serial module and supported for Linux and Windows.
