Model 7841 H.265 4-CH HD/SD Video Encoder

The Model 7841 4-Ch H.265 HD/SD Video Encoder compresses video and audio signals, multiplexing them with metadata and other system information for real-time video transmission applications. The 7841 is capable of simultaneously encoding four channels of video with resolutions up to 1080p. Utilizing the H.265 (HEVC) video compression algorithm, the encoder provides high-quality video transmission at various resolutions and a wide range of bandwidths. The H.265 compression algorithm utilizes highly bit-efficient coding to provide encoded streams at nearly half the bandwidth of its H.264 (AVC) predecessor. The unit is built on an advanced, low-power multimedia architecture that provides the horsepower for the computationally intensive H.265 algorithm, providing bandwidth efficiency for multi-channel applications. This increased efficiency allows for more channels to be transmitted over a given bandwidth, better quality video for constrained bandwidth applications, or lower bandwidth operation to extend the limits of ISR operation and reduce storage size requirements. A “Primary/Secondary” encoding feature enables a second, lower resolution, lower bit rate copy of each video input to be independently configured and streamed simultaneously for a maximum of four streams. The 7841 also provides an H.264 mode to support legacy infrastructures while providing a future growth path to H.265.

Designed for any video transmission application, the Model 7841 4-CH HD/SD H.265 Video Encoder 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.

The 7841 is easily integrated into any FMV system, providing for legacy composite and all SDI 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.
