The TG73A is an MPEG-2 TS (Transport Stream) Signal Generator conforming to both MPEG-2 system specifications and transmission and operating conditions for the ISDB-S BS digital broadcasting.
It enables to record an MPEG-2 TS, in which signals required for audio/video tests of Digital IRD (DIRD) and Set Top Box (STB) are multiplexed, and an ISDB-S TS having a frame configuration in which TMCC of BS digital broadcast is multiplexed, in the built-in hard disk drive (HDD). The recorded signals can continuously be output at the designated bit rate.
By combining the TG73A, ShibaSoku's RM73A satellite digital modulator which can cope with a wide-range bit rate and features good versatility and expansion and ShibaSoku's RC931A synthesized frequency converter, you can obtain compact "ISDB-S central digital signal source system".
