The NetPlus™ M400 is a broadcast-grade, satellite integrated receiver/decoder (IRD) that supports a wide range of global standards for video and audio compression. It sports a highly robust set of standard features, including DVB-S/S2 demodulation capabilities and inputs for DVB-ASI and IP. Every unit supports MPEG-2 and H.264 video compression — from the 4:2:2 format to SD and HD formats — as well as MPEG, Dolby® Digital AAC and SMPTE 302 audio systems.
Building on the industry-leading Harris experience in multichannel audio transport, this IRD features the AVTrack™ frame-alignment system for Dolby® E audio alignment, and is available with a factory-fitted option for an integrated Dolby® E decoder.
The M400 supports vertical ancillary data space (VANC) transport, wide-screen signaling (WSS), active format description (AFD) and other related data signals, as well as DVB fixed-key decryption (BISS) and DVB Common Interface (DVB-CI) descrambling methods.
Options for the M400 include an advanced demodulator that adds DVB-DSNG and 16/32 QAM DVB-S2 modes for the full range of satellite transmission standards currently in use worldwide.
The NetPlus M400 is the ideal solution for on-the-fly, multiformat, multi-standard contribution and distribution environments. With a full arsenal of supported standards and features, the M400 is up to the task, for every feed, every day.
The NetPlus M400 receiver/decoder is offered with several options. The standard base unit — M400-STD (4:2:0) — can optionally support DVB-compliant descrambling and conditional access. The professional unit incorporates 4.2.2. support, and offers options for DVB-compliant descrambling and conditional access, integrated Dolby® E audio decoding, advanced demodulation schemes and multiple methods of system configuration and control.
