Low Delay Lightweight Wireless COFDM Video Transmitter 1080P HD UAV Transmitter
Introduction:
Such new design 1080P HD transmitter is a powerful HD transmit system,using the core of mobile communication technology COFDM(multi-carrier modulation technique),which can transmit good quality and stable full-hd digital video signal under the condition of high speed mobile and heavy building blocks transmission in city environment.Support full HD 1080P H.264 encoding format and HDMI/SDI two HD inputs(single selection) as well support stereo balance audio input and narrowband transmission system.
Features:
- Low delay,lightweight,live broadcast;
- Support Full- HD quality image;
- Support 1080i/1080P HD transission;
- COFDM modulation;
- Built-in with HDM or HD-SDI interface(single selection);
- Support composite standard video and balanced audio input;
- All parameters can be adjusted by user;
