IPTV to DTMB national standard modulator * 4 carriers (digital QAM modulator, capable of supporting DVB-C/DTMB standards)
1.1 Equipment Introduction
The IPTV to DTMB Modulator is a high-performance and cost-effective IP-to-DTMB national standard modulation device specially designed for commercial venues to solve the digital TV signal source problem. The rear panel of this device has 4 hundred-megabit network ports, and the front panel has 1 gigabit network port for input, and 5 network ports are all for IPTV signal input. The front panel has 1 RF output port and 1 network management port. The RF port supports 4/8 (optional) DTMB or DVB-C (optional or achievable through upgrading software) single-carrier output. This device has the characteristics of high performance and low cost, and is very suitable for various commercial venues (such as hotels, guesthouses, clubs, tea houses, etc.) to use as the digital TV front-end system.
