Introduction:
The broadcast quality shows that this system is an ideal solution to meet all necessary requirements of broadcasting missions. The latest technologies of COFDM modulation and MPEG-2 video compression can guarantee the wireless transmission with high definition video and stereo audio. In addition, this system adopts some other technologies such as: A/D conversion, SDI (Serial Digital Interface), Composite and S-video input, Balanced audio input. The system resolves the multi-path interface problem and the diversity receiving technology greatly improves the receiving quality even in high-speed mobile condition.
Features:
1.COFDM modulation,MPEG-2422 ML 4:2:2 and MP ML 4:2:0
2.NLOS(Non Line-of-sight) wireless video transmission
3.SDI, Composite and S-video input, Balanced audio input
4.Several wavebands available: VHF/L/ S
5.Compact size, light weight, low power consumption
6.Transmission security by encryption of AES 128 bit/ALLTECH Basic Scrambling
7.Adjustable frequency range
8.8MHz output frequency bandwidth
9.Selectable TS rate (6MHz and 12MHz)
10.MPEG-2 video compression with a maximum speeding rate of 15Mbps
11.Transmission range can be up to 3km in NLOS(non line-of-sight)condition;
And more than 50km in LOS(line-of-sight)environment
