Miranda IRD-3811-DVB-S2 Integrated receiver/decoder with ASI and QPSK/8PSK inputs - IRD-3811-DVB-S2
The IRD-3811 combines RF demodulation and MPEG-2 decoding of ASI transport streams to either HD or SD. It also offers processing of key video and audio parameters, and signal probing functions for feed aggregation, distribution and monitoring applications by broadcasters and TV services providers. DVB-ASI, ATSC off-air or DVBS/S2 satellite signals fed to the IRD-3811 can be demodulated and decoded to provide either HD or SD video with embedded multichannel audio, in all leading formats, as well as composite video and stereo analog audio for monitoring. The IRD is also available with a DVB-CI slot, supporting leading conditional access systems, and allowing descrambling of multiple encrypted services. With its optional Gigabit Ethernet port, the IRD-3811 can also act as a gateway, by performing IP encapsulation of the input transport stream in either RTP or UDP mode.
Key Features
Input/output versatility
Single 8-VSB or QPSK/8PSK RF input
