The Miranda IRD-3111-DVB-S2 SD MPEG Receiver/Decoder with ASI and QPSK/8PSK Inputs combines RF demodulation and MPEG-2 decoding of ASI transport streams to SD video. It also provides processing of key video/audio parameters and signal probing functions for feed aggregation, distribution, and monitoring applications by broadcasters and TV service providers. The DVB-ASI, ATSC off-air, or satellite signals fed to this receiver/decoder can be demodulated and decoded to provide SD video with embedded multi-channel audio in all leading formats, as well as composite video and stereo analog audio for monitoring.
With its Gigabit Ethernet port (sold separately), this receiver/decoder can decode an incoming IP stream, or act as a gateway by performing IP encapsulation of an input RF or ASI transport stream in either RTP or UDP mode. It also provides optional video signal processing with frame synchronization and selectable delay, proc amp, aspect ratio conversion, and upconversion to HD.
The IRD encoder/decoder can decode an extensive range of Metadata, such as CEA-608 compliant closed captioning, Teletext, AFD, V-chip, and DVITC Time Code, which can be embedded in the decoded SDI signal. Transport Stream Metadata, such as PSIP can also be analyzed.
Moreover, its audio processing capabilities are also extensive, with dual audio decoding of MPEG-1 and Dolby Digital (AC-3) 2.0 audio. Optionally, the IRD-3111 encoder/decoder also performs embedding of decoded Dolby Digital (AC-3) 5.1 audio, with discrete 8-channel output.
In addition, this receiver/decoder performs a wide range of signal quality probing, with user-defined alarm settings on an extensive range of transport stream parameters that include TR 101 290 alarms, transport stream structure analysis, and individual program statistics.
This encoder/decoder is used for decoding of MPEG-2 multi-program or single-program ASI transport streams, IP encapsulation of ASI transport streams, and program aggregation in TV service-provider headends.
