Recently, the State intellectual property Office successfully approved Berry's invention patent application-"difference detection and sub-regional dynamic coding methods in remote desktops, electronic devices, computer-readable storage media"! The patent of the invention is the first in the domestic remote control industry, and has been successfully applied in the national-level remote control of Berry sunflower for many years, which significantly optimizes the picture quality experience under the remote control scene, while reducing data transmission, saving network bandwidth and reducing delay. it ensures the best visual effect of the Berry sunflower remote control picture.

After years of polishing algorithm, the invention patent application has been successfully passed.

Berry sunflower, as a national-level remote control brand, has always been ahead of the industry in technology since it was launched in 2009. As the first home-made remote control software independently developed, Sunflower has more than 17 years of technology accumulation in Berry, and its R & D team successfully launched the "SADDC" algorithm using the above invention patent, which has become one of the few self-developed algorithms for remote control scenarios in the industry.

The full name of SADDC algorithm is "Sunlogin Advanced Desktop Dynamic Codec", that is, "Sunflower Advanced Desktop dynamic Codec". This algorithm adopts different coding strategies for different remote control scenarios, which can significantly improve the picture compression ratio, reduce the amount of data transmission, and achieve very low delay coding and high frame rate transmission. This algorithm is a collection of multiple decoding strategies. At present, the core strategy of SADDC algorithm has the following three points:

● is based on focus application and visual saliency theory (visual saliency) to recognize and distinguish remote control pictures in real time.

● carries on the intelligent slice partition to the picture, realizes the partition block decoding operation.

● makes more efficient use of the configuration of the host. When the configuration of the host is sufficient, it can further improve the quality of remote control with hardware acceleration.

Sunflower self-developed SADDC algorithm, different from the general video codec algorithm, has done a lot of optimization for the remote control desktop environment. Among them, the SADDC algorithm will intelligently slice and partition the picture, which can be refined to thousands of blocks according to the complexity of the picture, and intelligently judge the changes of the picture, and only recalculate, compress and transmit the blocks with changes in the picture.

In this way, it solves the problem that the general coding and decoding algorithm will produce a large amount of redundant data when compressing the whole picture, greatly reduces the demand for computing power, and realizes the consideration of low network bandwidth, low delay, high definition and high frame rate picture quality. thus it breaks through the difficult problem of the domestic remote control industry.

The development of SADDC algorithm successfully solved the problem of insufficient computing power of CPU at that time, and at present, with the continuous development and iteration of technology, it has successfully solved the transmission problems of 4K HD, 4:4:4 lossless color and 144Hz high frame rate picture when remote control, and continues to lead the domestic remote control industry. As early as 2020, Berry has submitted an application for an invention patent for this algorithm, which has been successfully approved and announced recently.

The first patent for picture optimization in the field of remote control, technology leading the industry

It is reported that at present, most of the domestic remote control products still use general video coding, and when remote picture transmission, it is impossible to achieve fine-grained optimization similar to the "SADDC" algorithm, so it is often difficult to take into account low network bandwidth consumption, low delay, high-definition, high-frame rate picture transmission, unable to fully protect the user experience.

Sunflower successfully solved the problem of remote control through technological innovation, and finally achieved many indicators such as fluency, frame rate, picture quality and so on, which are far higher than other similar remote control products. Among them, not only is Berry's self-developed algorithm "SADDC" for remote control scenarios, but the above patent is also the first patent on remote desktop image quality optimization in the field of remote control in China.

In fact, the technical breakthrough of remote control is an arduous task, and few manufacturers in the industry have successfully applied image algorithms for remote control scenes, but finally, after overcoming numerous difficulties, Berry completed the feat of developing SADDC algorithm from scratch and successfully applied it, which has become an important benchmark in the field of remote control. Of course, behind the successful algorithm, it is inseparable from the great efforts and long-term investment of the Berry sunflower team, as well as more than 17 years of technical accumulation.

Summary:

It is Berry's perseverance and extreme pursuit of technology over the years, as well as the continuous polishing of technical details, that enable Berry to constantly break through the technical bottleneck and create the advantages of today's sunflower in remote control and remote connection technology. it has a low-delay smooth picture and a high frame rate of 144 frames, which is difficult to achieve in the industry, which far exceeds similar domestic remote control products. It can even be said to lead the development of the whole domestic industry.

Of course, technology will eventually give back to the experience, as exemplified by the sunflower's increasingly excellent remote control experience. In the future, we have reason to believe that sunflowers can further seek technological breakthroughs to promote the sustainable development of the potential field of remote control.
