FPV audio and video transmission: 

FPV is the abbreviation of English First Person View, that is, "first person perspective", it is a remote control aviation model or vehicle model on the addition of wireless camera transmission equipment, on the ground to see the screen control model of the new play. It has the characteristics of strong anti-interference ability, long distance and low delay.

The transmission characteristics of analog wireless audio and video modules used in this product are as follows:

1. ISM band frequency modulation modulator such as 1.2G/2.4G/5.8G can be used to directly input and output video signals through a pin fixed channel without external microcontroller;

2. The receiver can select the frequency to receive the video signal by setting the SPI mode;

3. Integrate two audio subcarrier modulators with frequencies of 6MHz/6.5MHz respectively to transmit audio signals, realizing two application modes of stereo and mono;

4, with RSSI voltage output function, can monitor real-time radio signal strength;

5, high sensitivity FM/frequency shift keying receiver operation, with good anti-noise and anti-attenuation performance;

6. The simple architecture design of single-chip SOC provides smaller application size and more cost advantages than discrete devices.
