GQ-3680N

上市日期: 2020-04-09

Main Features

· Support ITU-T J.83 Annex A / C modulation, output frequency range: 48MHz ~ 866MHz

· QAM mode can work in 16QAM, 32QAM, 64QAM, 128QAM, 256QAM

· Support up to 4 CASs with the same secret and DVB-CSA scrambling

· The reuse part supports automatic generation and manual upload of SI / PSI information;

· The network parameters of data input and output can be flexibly configured, and the input code stream can be automatically detected

· The IP interface supports bursts and uniform input streams, and performs uniform code reformulation on the streams to improve the output stream efficiency



This device is a new generation of multi-function modulator (DVB-C). A single IP / modulation board has 2 IP inputs, multiplexing, scrambling and multi-channel modulation functions. The device supports up to 3 boards and 72 frequency points. Modulation. This device adopts 'module management function', which can well meet the current and future digital TV system requirements of customers. In terms of management and maintenance, it supports Web-based management.
