IRD-3111
Standard definition receiver/decoder with ASI and RF inputs
The IRD-3111 combines RF demodulation and MPEG-2 decoding of ASI
transport streams to SD video. It also provides processing of key video
and audio parameters and signal probing functions for feed aggregation,
distribution, and monitoring applications by broadcasters and TV service
providers.
DVB-ASI, ATSC off-air or satellite signals fed to the IRD-3111 can be
demodulated and decoded to provide 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-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 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 are also extensive,
with dual audio decoding of MPEG-1 and Dolby Digital (AC-3) 2.0 audio.
Optionally, the IRD-3111 also performs embedding of decoded Dolby
Digital (AC-3) 5.1 audio, with discrete 8-channel output.
In addition, the IRD-3111 performs a wide range of signal quality probing,
with user-defined alarm settings on an extensive range of transport stream
parameters, including TR 101 290 alarms, transport stream structure
analysis and individual program statistics.
The IRD also provides optional video signal processing with frame
synchronization and selectable delay, as well as proc amp, aspect ratio
conversion and upconversion to HD.
