Wireless Transmission COFDM Modulation UAV Video and Data Transmitter for Drones 30km Range AES128/256bits Encryption
Such new design 1080P HD transmitter KP-HDT2W 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 HDM-I/SDI two HD inputs(single selection) as well support stereo balance audio input and narrowband transmission system.
Features:
1. Low delay, lightweight, live broadcast;
2. Support Full- HD quality image;
3. Support 1080i/1080P HD transmission;
4. COFDM modulation;
5. Built-in with HDM-I or HD-SDI interface(single selection);
6. Support composite standard video and balanced audio input;
7. All parameters can be adjusted by user;
