This equipment integrates with 4 to 40 channels MPEG-I Layer2 stereo audio encoder, Multiplexer, Scrambler, Modulator, and IP function, can be widely used in security monitoring, emergent broadcast and CATV.
This equipment supports 4 to 40 channels stereo audio input, 1 ASI input & output, 1 QAM modulation RF output optional, 1 TSoIP port. The modulating multiplexing TS stream can input DTMB China national standard system to constitute emergent broadcast system. After QAM modulation, signal can immediately output or mix with original CATV signal and then output, QAM modulation signal can be received by DVB-C standard TV or STB.

The performance price ratio is one of the most important factor to the company development. Therefore, we built our own base of production with 2 million annual production capability of digital TV system related devices in Shenzhen due to the low production cost there. We have the advanced ESD(Electro-Static Discharge) electrostatic comprehensive protection facilities, and have imported some advanced production and inspection equipment, including 7 SMT(Surface Mount Technology) production lines, 4 sets of AI(Automatic Insertion) equipment, 4 DIP(Double In-line Package) production lines, 7digital STB assembly lines, ect TELECAST was responsible for the key products research and development of the provincial government. And we have the high-tech patents and the software copyrights in digital TV(streaming media) and wireless transmission technology. We are one of the three companies with the FTTA(Fiber Through The Air ) full technology in the world.
