IP-DTMB four-way national standard digital modulator
Introduction: The IP-400T 4 network port IP DTMB modulator is a high-performance, cost-effective IP-to-DTMB national standard modulator that is newly developed by our company to solve digital TV signal sources for commercial locations. The front panel of the device consists of four 100M network ports. The four network ports are IPTV inputs. The rear panel consists of one RF port, two IP ports and one USB port. The RF port supports 3/4 DTMB single carriers. Output, 2 network ports are 1 channel 100 Mbps/Gigabit adaptive IPTV output and network port (mainly selected program). The device has high performance and low cost, and is very suitable for use in digital TV front-end systems in various business places (such as hotels, clubs, restaurants, etc.). Features: 1. Support 4-way 100M IP input, UDP, RTP protocol 2. Support 1 Gigabit IP output 3. Support 1 RF output interface, 3 or 4 DTMB single carrier output 4. Single U chassis, a single device integrates a set of front-end device functions, saving the user room space for the user 5. Support Web network management Technical Parameters: Input: 4-channel 100M IP input, UDP, RTP protocol modulation: Modulation standard GB20600-2006 Modulation channel 4 national standard single carrier output Constellation 4QAM, 16QAM, 32QAM, 64QAM RF output: Output channel 1 RF output interface, 4 DTMB single carrier, F head, 75Ω impedance Frequency range 50~900MHz, 1kHz stepping Output level -20dBm~0dBm MER≥40db IP output: Support 1 channel Gigabit IP output System: Chinese operation interface Support network upgrade General: Size (length × width × height) 430mm × 180mm × 40mm Temperature range 0~45°C (working); -20~80°C (storage) Power supply requirements AC 100V ± 10%, 50 / 60Hz AC 220V ± 10%, 50 / 60Hz
