NDS398X Series HD IRD

Outline

NDS398X Series HD IRD can decode TS signals from ASI, tuner (DVB-C/DVB-S/S2/ISDB-T optional) or IP sources into audio and video signal. The device supports up to 1080i HD decoding and MPEG-2 and H.264 compressing standard. Moreover, it supports ISDB multiplexing function. After multiplexing the TS signals from tuner, ASI and IP sources according to the ISDB-T standard, then output ASI and IP (UDP) signals. Furthermore, it is equipped with CI descramble module. It also supports LCD, keyboard and SNMP /web management.
