The IRD-3802 combines MPEG-2 and H.264 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.
DVB-ASI or IP transport streams fed to the IRD-3802 can be decoded to provide either HD or 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, 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.
The IRD also provides optional video signal processing with frame synchronization and selectable delay, as well as proc-amp, up/down/cross conversion 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 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-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.
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 101290 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.
