The IRD-3111-VQ SD Receiver/Decoder with ASI and 8VSB Inputs from Miranda combines RF demodulation and MPEG-2 decoding of ASI transport streams to SD video. It also provides processing of key video and audio parameters as well as signal probing functions for feed aggregation, distribution, and monitoring applications by broadcasters and TV service providers.
TheDVB-ASI, ATSC off-air or satellite signals fed to the IRD-3111-VQ SD 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. The IRD is also available with a DVB-CI slot (optional), supporting leading Conditional Access Systems, and allowing descrambling of multiple encrypted services.
With its Gigabit Ethernet port (sold separately), the IRD-3111 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.
The IRD also offers video signal processing (sold separately) with frame synchronization and selectable delay, as well as proc amp, aspect ratio conversion, and up conversion to HD.
The IRD 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.
The audio processing capabilities of the IRD-3111-VQ SD Receiver/Decoder are wide-ranging, thanks to the dual audio decoding of MPEG-1 and Dolby Digital (AC-3) 2.0 audio. Additionally, the IRD-3111 performs embedding of decoded Dolby Digital (AC-3) 5.1 audio, with discrete 8-channel output (optional).
In addition, the IRD-3111 performs a broad range of signal quality probing, with user-defined alarm settings on a wide range of transport stream parameters, including TR 101 290 alarms, transport stream structure analysis, and individual program statistics.
