Product Description

The MREN-680 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 MREN-680 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.

The MREN-680 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. Designed for any airborne application, and specifically military ISR missions.
