No Longer Available

The Miranda IRD-3101 SD MPEG Decoder with ASI and GigE IP Inputs provides MPEG-2 decoding of ASI and IP 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 or IP transport streams fed to the IRD-3101 can be decoded to provide SD videos 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, the IRD-3101 can also act as a gateway, by performing IP encapsulation of the input 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-3101 feature dual audio decoding of MPEG-1 and Dolby Digital (AC-3) 2.0 audio. In addition, the IRD-3101 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.

 

 

Note! Optional video signal processing with frame synchronization and selectable delay, as well as proc amp, aspect ratio conversion and up conversion to HD.
Optional embedding of decoded Dolby Digital (AC-3) 5.1 audio, with discrete 8-channel output.

Input/Output Versatility

Dual ASI transport stream inputs
Single ASI transport stream output for signal monitoring or distribution
IP transport stream input/output: an ASI signal can be re-transmitted as IPor an IP stream can be forwarded as ASI
IRD acts as IP video gateway with forward error correction (FEC) for improved quality
Dual SD-SDI outputs (HD/SD-SDI) with up converter option
Composite video and stereo analog audio monitoring outputs

Easy Input and Program Selection

Manual or automatic input selection mode
Automatic mode allows switching to backup input upon loss of signal on active input, with adjustable duration
Program selection using local control or iControl
MPTS automatic program selection mode and recovery
The IRD can decode signals in either 720 x 486i 59.94 or 720 x 576i 50 formats
