1.2.4RX8320 ATSC Broadcast Receiver

The RX8320 is specifically designed to enable a simple, reliable solution to the ATSC broadcast transition for cable, telco or satellite operators who re-transmit the local broadcast channels.

The RX8320 provides both ASI and 8-VSB inputs for reception of the broadcast services over terrestrial or fiber links. It then provides a pass-through capability so that operators can carry the digital signals all the way to a subscriber’s home.

To support analog TV, delivery the RX8320 also provides video decode capability with high quality composite output and audio decode capability, including 5.1 multi- channel to stereo down-mixing, to allow easy interfacing into the existing infrastructure.

Any high definition (HDTV) digital TV service can be down-converted for analog SD delivery. Automatic picture aspect ratio conversion is performed based on any active format description (AFD) and bar data present on the incoming digital TV service.

Legal and regulatory requirements are also fulfilled by the RX8320 for the transition of ATSC broadcast services into analog TV delivery, with the extraction and insertion of closed captions, Nielsen data, TV Guide data, and V-Chip program rating information into the analog video outputs.
