Datasheet
IRD-3802
MPEG Decoder with ASI and GigE IP Inputs
Space-saving, modular platform for advanced signal processing.
The IRD-3802 from Grass Valley, a Belden Brand,
provides MPEG-2 decoding of ASI and IP transport
streams to either HD or SD. 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
services providers.
The audio processing capabilities of the IRD-3802
are also extensive, with dual audio decoding and
selectable stereo downmix modes of decoded
MPEG-1 and Dolby Digital (AC-3) 2.0 audio.
Optionally, the IRD-3802 also performs embedding
of decoded of Dolby Digital (AC-3) 5.1 audio, with
discrete 8-channel output.
DVB-ASI or IP transport streams fed to the IRD-3802
can be 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 mutiple
encrypted services. With its Gigabit Ethernet port,
the IRD-3802 can also act as a gateway, by performing IP encapsulation of the input transport stream in
either RTP or UDP mode.
In addition, the IRD-3802 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 generates low-resolution
H.264 video proxy and 2-channel audio streams of
selected programs for monitoring.
The IRD also provides optional video signal processing with frame synchronization and selectable delay,
as well as proc amp, up/down/crossconversion
and aspect ratio conversion. The IRD can decode
an extensive range of metadata, such as CEA-608
compliant closed captioning, teletext, AFD, V-chip
and DVITC timecode, which can be embedded in
the decoded SDI signal. Transport stream metadata,
such as PSIP can also be analyzed.

IRD-3802 MPEG Decoder with ASI and GigE IP Inputs
Multichannel Aggregation in Headends
Television service providers typically have to deal with a wide range of
signal formats and encoding schemes when performing aggregation of
multiple channels in their headends. The IRD-3811 is an ideal tool for performing signal aggregation from either DVB-S or DVB-S2 satellite down
links or from the reception of ATSC terrestrial signals. Using an ultra-compact form factor of up to 10 decoders per 3 RU Densité frame, the IRD
combines extensive signal decoding with advanced processing functions
and probing.
With its ability to decode all leading video and audio encoding schemes used
in channel distribution, the Densité IRD can be used to receive signals from
miscellaneous sources, including satellite or terrestrial digital, in multiple formats, including ASI, IP or RF, MPEG-2, Dolby Digital or AAC.

For operators concerned about signal quality, the IRD provides transport
stream monitoring functions that include TR 101 290 alarming, program bit
rate monitoring, and analysis of the ASI transport stream structure.
With its up/down/cross conversion functionality, the Densité IRD offers the
TV service provider full control over the format of the signal it forwards into
its network. Incoming signals that are collected as HD can be downconverted to SD, with their 5.1 audio downmixed to 2.0. Similarly, the IRD can
convert SD signals into HD. The IRD also provides the ability to perform
frame synchronization of the decoded signal. To maintain the highest quality, the IRD provides control over brightness, saturation, hue and contrast
with its proc-amp functions.
