I/O Signal

RJ45 ethernet COFDM Transmitter for the IP camera video Transmission

This ethernet IP input COFDM Video transmitter module can receive video from an IP camera via an Ethernet connection with a built-in RTSP client and transmit it. On the COFDM receiving side, our COFDM module has a built-in RTSP Server that allows video streaming over Ethernet for remote software or hardware decoders.

How to use it as the COFDM Relay repeater module?

This module already has a TX transmission function. If you add a dual-antenna receiving module and combine them, you can form a COFDM relay/repeater module. बिल्कुल, you need to add a bandpass filter to filter out clutter interference and increase PA to transmit a longer range. If you need customization, कृपया हमसे संपर्क करें.

COFDM wireless transmission system transmission rate calculation

वायरलेस ट्रांसमिशन दर (air interface rate):

दर(एमबीपीएस) = (बैंडविड्थ(MHz) * 8.0/7.0) / (1+सैनिक) * 1512/2048*लॉग2(नक्षत्र बिंदु) * कोड_दर * 188/204.

Take the 8MHz bandwidth as an example of different protection intervals, convolutional bitrates, data rates corresponding to constellations, and the required received signal-to-noise ratio:

The receiver module has a 2*5PIN PH2.0mm connector which provides “keys + LEDs” signals. It is designed for customers who want to expand LEDs and keys to their cases.

PWR led signal: this two-pin can connect to an led for the power indicator, and constant light when the device is normally powered.

The link led signal: this two-pin can connect to an led for a wireless link indicator, which blinks when the video stream is received.

REC led signal: this two-pin can connect to an led for a record indicator, and constant light when video recording.

REC key signal: this two-pin can connect to a button for the switch of video recording, and a short press to change its status. The receiver will automatically check the storage device(micro SD card or USB disk) after powering on and start to record video when the storage device is inserted. Just press it to stop or record again.

Paired with COFDM transmitter:

The default normal features of the two-antenna Wireless receiver module can be paired with all of Our H.264 transmitter modules. The HD video latency from its inputting of the transmitter to the HDMI screen displaying of the receiver is about 200~250ms.

Our two-antenna COFDM Wireless Receiver module can also be paired with our COFDM transmitter module for the lowest video latency application when manufactured with specified firmware. The specified firmware enables proprietary H.264 video compression/decompression only using p-frames for the lowest latency. The video latency from its inputting of the transmitter to the HDMI screen displaying of the receiver is about 50ms to 130ms.
