Frequently Asked Questions:
Q1. Does your COFDM HD video transmitter support changing frequency
to be 1.2G/ 1.4G?
A:The transmitter frequency can be 160MHz~2700MHz, but our COFDM
wireless receiver only supports 170~860MHz, if you want 1.2G or
1.4G,then need to intall a frequency down converter at the receiver
end.
Q2. Does this COFDM HD transmitter support SDI video input?
A: Yes, our COFDM HD transmitters support HDMI, SDI, CVBS AV, IP
Ethernet RJ45 and AHD video input, please just let us know what
video type you prefer.
Q3. What's the max distance for the 2.5W PA transmitter?
A: For UAV application, the transmission range is about 50km, the
height of UAV is about 300 meters, and put the antennas of receiver
as high as possible.
Q4. Does your COFDM HD transmitter and receiver support standard
DVB-T protocol?
A: Yes, it supports 3 working modes:
- Standard DVB-T protocol, normal DVB-T can get the transmitter
signal, no encryption and decrryption function.
- COFDM protocol, support TX encryption and RX decryption, support
H265 and H264 encoding, but no super low latency.
- COFDM low latency protocol, H264 encoding with low latency, support
TX encryption and RX decryption function,
Q5.I want a set of COFDM HD video transmitter and receiver to
transmit two channels at the same time, one HDMI video and one
audio.
A: Our COFDM HD transmitters support one HDMI and one auxiliary
CVBS audio and video input at the same time. Currently, it can only
support one sound source, which can be modified by our parameter
configuration board, to choose HDMI sound or CVBS sound.
