Model 6820R 2-Channel HD / SD Encoder, Rugged

Delta Digital Video’s Model 6820R 2-Channel Encoder is an HD/SD video encoder that compresses video and audio signals, multiplexing them with metadata and other system information for real-time video transmission applications. The 6820R is capable of simultaneously encoding two channels of video with resolutions up to 1080p. Utilizing the H.264 (MPEG-4 AVC Part 10) video compression algorithm, the encoder provides high quality video transmission at various resolutions and a wide range of bandwidths. The unit is built on an advanced multimedia architecture that extends encoding to multiple channels without increasing size and power. A “Primary/Secondary” encoding feature enables a second, lower resolution, lower bit rate copy of the video input to be independently configured and streamed simultaneously for a maximum of four streams.

Designed for any airborne application, and specifically military ISR missions, the 6820R is compliant with the full motion video standards developed by the US Government’s Motion Imagery Standards Board (MISB). This includes compliance with the video compression, KLV metadata, and transport stream profiles required to ensure interoperability in US and Allied processing, dissemination, and exploitation (PED) systems. Full DO-160/MIL-810 environmental and EMI qualification ensures the 6820R meets flight-worthiness requirements.

The 6820R is easily integrated into any FMV system, providing for legacy composite or S-video inputs and all SMPTE standards. The unit provides Ethernet and synchronous serial transport interfaces along with multi-format metadata interfaces. Serial or Telnet control, and an easy to use web-GUI are provided for encoder set-up.
