COFDM Transmitter Send Receive Video Data From Ship to Land
Description
The vehicle live broadcast transmitter has the advantages of real-time picture, clear picture quality, simple equipment installation and strong maneuverability.
This model adopts the advanced COFDM modulation technology that enables high-speed real-time transmission of high-quality images in "non-visual conditions" during high-speed motion. The transmit distance can reach 10-30km from ground to ground, the unexpected results can be achieved in large-scale military exercises, on-site news gathering, real-time broadcast, media wireless live broadcast system and real-time dynamic monitoring!
Key Feature
1. Two way voice function; The transmitter end and receiver end can talk with each other.
2. A variety of signal input adaptive judgment, you can also arbitrarily select one input signal for transmission through the panel
