Integrated receiver/decoder
An integrated receiver/decoder is an electronic device used to pick-up a radio-frequency signal and convert digital information transmitted in it.
Professional IRDs
Commonly found in radio, television, Cable and satellite broadcasting facilities, the integrated receiver/decoder (IRD) is generally used for the reception of contribution feeds that are intended for re-broadcasting. The IRD is the interface between a receiving satellite dish or Telco networks and a broadcasting facility video/audio infrastructure.
Professional IRDs have various features that consumer IRDs lack such as:
- 4:2:0 / 4:2:2 video decoding.
- SDI outputs.
- ASI inputs / outputs.
- AES/EBU Audio decoding.
- VBI reinsertion.
- WSS data and pass through.
- Transport stream demultiplexing.
- Genlock input.
- Frame synchronization of digital video output to analogue input
- Closed captions and VITS/ITS/VITC Insertion.
- Video test pattern generator.
- Remote management over LAN/WAN.
- Rack mountable.
Uses
- direct broadcast satellite (DBS) television applications like DirecTV or Astra
- fixed service satellite (FSS) applications like VideoCipher, DigiCipher, or PowerVu
- digital audio radio satellite (DARS) applications like XM Satellite Radio and Sirius Satellite Radio
- digital audio broadcasting (DAB) applications like Eureka 147 and IBOC
- digital video broadcasting (DVB) applications like DVB-T and ATSC
