Model 7840R 4-CH H.265 Rugged Video Encoder
Delta Digital Video’s Model 7840R 4-Channel H.265 Rugged Video 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 7840R 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. The 7840R also provides an H.264 mode to support legacy infrastructures while providing a future growth path to H.265.
Designed for any rugged airborne, ground-mobile, or shipboard application, the 7840R 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 MIL-STD-810 environmental and MIL-STD-461/DO-160 EMI qualification ensures the 7840R meets project requirements.
The 7840R 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.
