When we make full use of UAV video transmitters, video has an inevitable delay, but that doesn't mean we have to endure several minutes of delay. What is the video latency of a drone video transmitter? How can you reduce it to improve the user satisfaction? That's one of the things we've been working on for a long time.

How to Understand Drone Video Transmitter Video Latency?


In the video world, latency is the amount of time between the moment when a video frame is obtained and the moment when the frame is displayed. Low latency is the design goal of any drone video transmission system that interacts with video content in real time, such as video meetings or UAV communication solutions.

But the understanding of low latency is different towards different people, and there are different ways to achieve low latency of drone video transmission system. This article will define and explain the basics of wireless video transmitter video latency and discuss how to correctly select wireless video transmitter solutions that have the greatest impact on latency.

There are many steps between the wireless video transmitter seizing the image and the display pixel. The delay contributed by each of these processing steps, together with the time needed to send the compressed video package, creating a total delay of wireless video transmitter, sometimes called end-to-end delay.

 

What Is Low Latency of Drone Video Transmitter?


There is no general absolute definition of low latency; instead, what is acceptable towards different people from distinct standards.

When humans interact with video between COFDM UAV video and data links or while just having fun, delays of less than 100 milliseconds are considered low enough because they do not affect the experience of most people. But in applications where machines interact with video, such as in many automotive, industrial and medical systems, the latency requirements are much higher: 30ms, 10ms, or even less than a millisecond, depending on the system requirements. There is also the term ultra-low latency applied to video processing capabilities and IP kernels, which is a COFDM UAV video and data links marketing concept rather than a technical definition that simply means "lower latency" for some UAV communication solutions.


How to Reduce Drone Video Transmitter Video Latency?


In the process of wireless video transmitter transmission, the image is not clear, and the delay of wireless video transmitter is not desirable for users and businesses. So today we talk about how to solve the problem of wireless video transmitter delays. In the use of drone video transmission system, we find that video delay phenomenon occurs with high probability, which is caused by the adoption of HD monitoring equipment. In the contemporary monitoring drone video transmission system, users pursue high definition and smoothness, which is not something that can't have both.


1. Decoder performance

The so-called decoder generally refers to the decoder itself or the client used for decoding, if the client host configuration. The quality of long-range wireless video transmitter and decoder is easy to affect video decoding speed, if the quality is not good, it is very easy to appear video delay or stuck screen phenomenon. However, it should be noted that sometimes buffering of long-range wireless video transmitter is automatically added during decoding or encoding in order to maintain video smoothness, which is also prone to some slight delay.


2. Transmission lines

The choice of high-quality wireless video transmitter is an important measure to reduce the delay. When wired transmission is natural it is network cable, and when wireless video transmitter should choose high quality transmission equipment.


3. Relay equipment

In the transmission process, each jump represents an increase in processing time of the transit device, so the more times of jumps, the greater time loss will be caused. Therefore, when designing the transmission route, reducing the number of hops can effectively reduce the delay phenomenon of long-range wireless video transmitter.

 

This is how you are brought to the UAV video transmitter video delay, and I hope this will to some extent help you. Our drone video transmitter can not only realize long-distance image transmission with a length of 50km, but also has excellent performance with a latency of less than 50ms.
