HDMI SDI CVBS Inputs COFDM Video Transmitter Module 300Mhz ~ 860MHz
COFDM Video transmitter module Introduction:
Feature and port:
- H.264 video decompression playback function, maximum support 1080P@60fps decoding playback, backward compatible with other various resolutions, frame rate decoding playback. It can realize the low-latency high-definition digital wireless image transmission function. The minimum video delay can be about 60ms at 720P@60fps, and the minimum video delay can be about 130ms at 1080P@60fps. This delay refers to the delay from the HDMI video input at the transmitter to the HDMI output display at the receiver, excluding the delay of the front-end camera at the transmitter (we measured the delay of a certain brand of SLR camera to be around 70ms, and a well-known brand of sports camera to have a delay of around 130ms).
- Audio and video output:
- HDMI-A type port audio and video output (HDMI out)
- AV audio and video output (6PIN port)
- USB Host interface output to mobile phone or tablet
- Ethernet port output
- Support AES decryption function (match the encryption of the transmitter, set the password through the configuration panel)
- Parameter configuration serial port (Config UART): It can be connected to a PC or a parameter control panel for parameter configuration, and it can also be connected to other upper computers for parameter configuration (such as drone remote control). Config UART is TTL 3.3v level.
- Transparent data transmission serial port (Data UART), TTL 3.3v level
- USB Host port
- External U disk/mobile hard disk storage
- Stream the video to the mobile phone/tablet, and realize the simultaneous display of HDMI, AV and mobile phone video at the same time
- TF card interface (used for software upgrade and maintenance, data storage, etc.)
- Keys+LEDs: can lead to power indicator light, RF signal receiving indicator light, record indicator light, OSD on/off button, Record
