IRD-3802
MPEG Decoder with ASI and GigE IP Inputs

The IRD-3802 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. 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.

Input/output versatility
