FPV audio and video transmission:&n✘≤bsp;
FPV is the abbreviati×↔on of English First Person View, that ♠φ≥is, "first person perspecti©>λve", it is a remote control aviat€¶ion model or vehicle model on δ÷←the addition of wireless c∑αamera transmission equipment, ¶☆<on the ground to see the screen conβπΩ✘trol model of the new play. It h©&£♠as the characteristics of stron €λg anti-interference ability,γ♦¥ long distance and low delay.
The transmission characteristics of ✔☆ analog wireless audio and ÷↔' video modules used in this product ar↔≠e as follows:
1. ISM band frequency modulatioγ®↔n modulator such as 1.2G/2.4G/5.8G €₹γcan be used to directl•<y input and output video signa♣♣≈ls through a pin fix≠λ>✘ed channel without extern¥₹™al microcontroller;
2. The receiver can select the frequen• ♥cy to receive the video signal b¶←₩y setting the SPI mode;
3. Integrate two audio subcarrier modσ•≠ulators with frequen α♥cies of 6MHz/6.5MHz respect$≈↕ ively to transmit audio sign™♠als, realizing two appli σ&cation modes of stereo and mono;
4, with RSSI voltage output funπ★→ction, can monitor rea αl-time radio signal strength;
5, high sensitivity FM/frequ©✔₽ency shift keying receiver operation, w$✔ith good anti-noise and anti-×δ€attenuation performance;
6. The simple architecture desig↑£≠ n of single-chip SOC p♥★rovides smaller appliε↕≠cation size and more cost advaσ≠φntages than discrete device δs.
