Introduction of HD COFDM Transmitter:
The is a mini HD 1080P COFDM video transmitter, which uses the 4th generation mobile communication core COFDM multi-carrier modulation transmission system. It has high efficiency innovative H.264 compression encoding, integrated with lightweight, low power consumption of OLED display control panel, integrating digital modulation, and highly integrated HD moving LOS and NLOS digital video transmission equipment. Built-in with HDMI or HD-SDI hd interface. It can transmit high quality full 1080P hd video and audio even though there are some building blocks or high-speed mobile shooting. It’s widely used in UAV aviation filming, military, broadcast, police, covert investigation, image monitor or real-time wireless video transmission and so on.
Features of HD wireless video audio transmitter:
1. Light weight: 195g only (without battery);
2. COFDM modulation, H.264 compression;
3. HDMI/SDI ports;
4. Support 1080P/720P resolution;
5. replaceable Li-battery with high capacity power;
6. Support NLOS (None Line of Sight), high-speed mobile transmission;
7. Highly integrated modular combination design;
8. high light and low power consumption of the OLED display control interface.
