1.Overview

1.1 Product features and usage

The ZHC518M-DVB-T2 modulator (hereinafter referred to as the modulator) supports four channels of ASI input stream and 2 channels of network streaming input, the input signal is modulated into a radio frequency signal and output by a fully digital modulation module. Supports RS encoding, interleaving and baseband shaping to receive DVB transport streams from encoders, multiplexers, DVB gateways, scramblers, video servers and more. The modulator complies with the European ground modulation standard and is one of the main devices of the wireless digital TV in front end.
