Integrated Receiver Decoder DVD922 is a Integrated Receiver Decoder designed to be used in CATV network Headend. DVD922 can be used for receiving both free-to-air and scrambled DVB services, and it can be used both for DVB-S and DVB-S2 reception.
DVD922 is a Integrated Receiver Decoder designed to be used in CATV network Headend. DVD922 can be used for receiving of both free-to-air and scrambled DVB services, and it can be used both for DVB-S and DVB-S2 reception. DVD922 front end has both DVB-S and DVB-S2 demodulators thus making it possible to receive the latest most advanced transmission schemes and exploiting the increased capacity of DVB-S2. It also provides future proof video decoding solution supporting the
migration from MPEG2 to MPEG4 AVC and supports seamless migration from SD to HD picture quality. Where digital signal transport is needed DVD922 is equipped with ASI output in order to support that purpose. It is also equipped with dual CI slots with optional multi scrambling capability gives possibility to descramble the whole multiplex if supported by CA module. The DVD922 also provides high quality video and symmetric audio outputs supporting HD to SD conversion and audio down mixing. It also
include sophisticated service acquisition supported by versatile audio and subtitling language and modes selections. Robust operation and automatic recovery from errors are matter of course to this product. The DVD922 is also fully configurable using CATVisor Commander and a wide range of monitoring functions ensure reliable operation. DVD922 is fully compatible with DVX Headend System, and can be installed in standard DVX001 installation frame.
