As the epidemic continues and Internet technology develops, remote control technology is increasingly used in our daily lives and work, such as remote office, remote management, remote collaboration, etc. People no longer need to carry heavy laptops every day The computer is running back and forth, and you can remotely control the computer to complete the work just using your mobile phone or tablet.

As more and more people use remote control frequently and for a long time, speed has also become an important part of measuring remote control software. At present, the best reputation of domestic remote control software is ToDesk and Sunflower. Today we will compare The remote control speed of these two companies and the technical strength behind them.

[Speed ​​comparison: Who has lower latency]

For remote control software, it is not that easy to remotely control the computer screen in real time for no-delay operations. If the delay is too high, it is easy to get stuck on the screen. Remote control The speed will also slow down. To this end, I conducted latency tests and comparisons on the free and paid versions of Sunflower and ToDesk.

is first of all a free version that also focuses on free and unlimited speed. Among them, the delay of Sunflower’s free version is 18ms. Although this delay does not look high, there are lags during actual use. Remote operation documentation The response is slow when typing. Whether it is the mouse wheel or typing input, it takes more than 3 seconds to get a response. From time to time, the host is not online and displays error code 409. The server is also somewhat unstable.

Sunflower free version delay situation

ToDesk's free version has a delay of 16ms. On the surface, the delay is lower. In fact, the mouse following in remote control is indeed significantly better than that in Sunflower, and watching videos through remote control is also smoother and smoother. Consistently, ToDesk is better in terms of latency in the free version, but the frame rate in is slightly inferior to ToDesk.

ToDesk free version delay situation

Let’s look at the two paid versions. Sunflower chooses the elite version, while ToDesk chooses the professional version. Through actual measurement, it was found that the difference in delay between the paid versions of the two platforms is obvious. In the same scenario of watching videos remotely, the delay of the paid version of Sunflower is not high, the smoothness of watching videos is higher than that of the free version, the picture quality is also clearer, and the experience is improved.

However, the paid version of ToDesk has better performance in both delay and frame rate. Not only the delay is as low as 1ms, but even the frame rate is above 30fps, making it difficult to control. Resolution, image quality and fluency are mapped one-to-one, and the experience is better than that of Sunflower.

[Technical comparison: Who has stronger technical strength]

Whether it is low latency or high image quality, it needs to rely on the remote control technology behind it to achieve it. Next, let’s take a look at the remote control technology capabilities of Sunflower and ToDesk.

• Sunflower self-developed SADDC algorithm

Sunflower specializes in self-developed video encoding technology. Through the self-developed SADDC algorithm, it has made a lot of optimizations for the remote control desktop environment. It not only intelligently slices and partitions the picture, but also solves the problem of compressing the entire picture with universal codec algorithms. It will cause the problem of a large amount of redundant data and greatly reduce the computing power requirements. It will also intelligently judge the change range of the picture and automatically reduce the frame rate to ensure smoothness and further reduce the amount of transmitted data.

• ToDesk integrates SD-WAN network + self-developed video encoder + RTC technology

ToDesk integrates three technologies to improve speed and image quality in all aspects. First of all, in order to improve the speed of remote control, ToDesk built an OTT SD-WAN network and a cloud-based relay network on the public network. uses AI algorithms to provide the optimal transmission solution for each connection. improves the overall remote control speed. The network transmission quality and stability are instantaneous, while also achieving lower latency for remote control.

Secondly, ToDesk's self-developed video encoder ensures the clarity of remote control image quality, and a large number of adaptations and optimizations are carried out from the bottom, especially for graphic, 3D, and high-definition scenes, which can reduce the problem of desktop high-definition transmission. Broadband requirements reduce remote control delays while improving image quality.

Overall, ToDesk's remote control delay performance is better than that of Sunflower. Technically, both companies have strong technical support. However, compared to Sunflower, which is a single technology, ToDesk's remote control technology is obviously more three-dimensional and integrated. , which may be the fundamental reason why ToDesk has gained the favor of 40 million users in just two years. What do you think of these two remote controls? Welcome to communicate together in the comment area.
