FPV Why choose not clear simulation image transmission?

When discussing why FPV (first-person perspective) drones choose unclear analog image transmission, we need to understand the reasons behind this choice from multiple dimensions.

First, we need to clarify the basic differences between analog image transmission and digital image transmission. Analog image transmission simulates image and audio signals into radio wave signals and sends them out, while digital image transmission converts these signals into digital format for transmission. Intuitively, digital image transmission usually provides clearer image quality due to its high resolution and low latency. However, analog image transmission has its unique advantages in certain specific situations, especially in the field of FPV drones.

For FPV drones, speed and real-time are key factors. FPV drones are usually used in scenarios such as racing or rapid crossing, which requires that the image transmission system must have extremely low latency. Since analog image transmission does not have an encoding process, it has significant advantages over digital image transmission in terms of delay. In racing, every millisecond of delay can cause deviations in the flight path and increase the risk of hitting an obstacle. Therefore, although the image quality of analog image transmission may not be as good as digital image transmission, its low-latency characteristics make it the first choice for FPV drones.

In addition, analog image transmission also has its unique features in terms of stability. In the case of insufficient transmission bandwidth or poor network conditions, analog image transmission can ensure stable data transmission by reducing the image quality, while digital image transmission may experience image interruption or frame loss in these situations. For FPV drones, this stability is crucial because any interruption of the image may lead to flight control errors.

Furthermore, from a cost perspective, analog image transmission also has advantages. Analog image transmission technology is relatively simple, the market is mature, and there are many suppliers and manufacturers, so the cost is relatively low. Digital image transmission technology is usually more complex and more expensive. For FPV drone enthusiasts with limited budgets, analog image transmission is undoubtedly a more economical choice.

Of course, this does not mean that digital image transmission has no application value in the field of FPV drones. In certain specific situations, such as when high-definition image quality is required for aerial photography or film and television production, digital image transmission undoubtedly has incomparable advantages. However, in scenes such as FPV drone racing or fast crossing, the low latency and stability of analog image transmission make it a more suitable choice.

In summary, the reason why FPV drones choose the unclear analog image transmission is not due to backward technology or cost considerations, but based on its advantages in many aspects such as low latency, high stability and cost-effectiveness. In specific application scenarios, analog image transmission can provide a more reliable and efficient flight experience.
