Product Overview

Easy Migration to ATSC Digital Terrestrial Reception

The RX8320 is specifically designed to smooth the ATSC broadcast transition for cable, telco and satellite operators who re-transmit local broadcast channels.

Complete Interoperability

The RX8320 ATSC Broadcast Receiver offers full translation capability between digital signaling and analog services. By offering automatic picture aspect ratio conversion and signaling via AFD and bar data, the RX8320 ensures that widescreen HD video is correctly displayed when down-converted to 4:3 SD video. Full support is provided to ensure that closed captions, TV Guide data and program rating (V-Chip) services continue to be supported.

Peace of Mind

MediaKind is a leading provider of ATSC broadcast headends and professional integrated receiver decoder (IRD) products worldwide. This in-depth knowledge and experience ensures that the RX8320 delivers the high quality and reliability on which broadcasters and service operators alike depend.

ATSC Broadcast Design

As local terrestrial broadcasters begin to phase out their analog broadcasts and transition to an all-digital environment, the need to maintain access to the viewing public becomes critical. In many cases, viewers receive these broadcasts through cable, telco or satellite operators who either provide an analog transmission to their subscribers or provide a digital means for their subscribers to receive these local channels.

The MediaKind RX8320 ATSC broadcast receiver is specifically designed to enable a simple, reliable solution to the ATSC broadcast transition for these operators.

The RX8320 provides both ASI and 8VSB 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 the subscriber.

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.
