Digital TV Headend 998X HD IRD,(DT-HDIRD-998X) 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.
