In the process of enterprise digitization, a series of "cloud acceleration" strategies such as business cloud, data cloud and service cloud can actually bring great "lightweight" advantages to the enterprise. Cloud computer (cloud desktop) is a very intuitive example.

For enterprises, cloud desktop is a way to cloud office equipment: after adopting cloud desktop solution, enterprises can appropriately reduce the deployment of professional equipment such as workstations and deploy some high-performance business requirements to the cloud. Employees, on the other hand, remotely connect to the cloud host to promote business processes and work through lighter computer equipment.

It is not difficult to see that the cloud desktop is actually a form of remote control in essence, and the difference is that the controlled end has changed from a physical device to a cloud device. Based on the similarity between the two, sunflower remote control as a national-level remote control brand, power cloud desktop direction, is very reasonable.

Berry CTO Zhang Xiaofeng (Tu Yuan Yunqi Conference)

At the cloud conference not long ago, Berry CTO Zhang Xiaofeng revealed that Berry sunflower will soon launch the "cloud desktop" function to empower enterprises with "cloud acceleration".

Here, let's briefly introduce what kind of technology and business framework is built by Sunflower's parent company Berry, what core remote connection technologies are stored, and how to lay a solid foundation for the upcoming cloud desktop.

Based on cloud platform: Berry's remote connection capability system

Berry's remote connection capability is based on Berry Cloud and combines hardware equipment and systems to form a series of professional application platforms, including standard SaaS service platforms, as well as SDK / API services (PaaS) that can be redeveloped and embedded.

Based on these professional application platforms, radiate the core value of remote connectivity to external users. As a representative product of these platforms, Berry Sunflower has a number of network and image-side patented technologies, breaking through the technical bottleneck of the industry, bringing users professional, smooth, convenient, secure and cross-platform remote control services to meet the needs of telecommuting, IT operation and maintenance, technical support and other scenarios.

Exclusive Technology: "SADDC" Codec algorithm based on remote Control scene

In the technical reserve specific to the application itself, the "SADDC" algorithm of Berry Sunflower is definitely the most noteworthy technology, which has a very significant effect on the remote control experience: through the reasonable combination of multiple image codec strategies, it allows users to have as high a remote control experience as possible with limited bandwidth.

The full name of the SADDC algorithm is "Sunlogin Advanced Desktop Dynamic Codec" and "Sunflower Advanced Desktop dynamic Codec". The algorithm includes three core strategies:

● combines the visual significance theory to intelligently analyze the application focus to identify and partition the remote control picture 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.

First of all, the sunflower SADDC algorithm tilts the bit resources to the highly significant regions according to the visual significance theory, which makes the key areas show a more smooth and clear picture, avoids putting too much resources into the non-significant areas and non-focus areas, and improves the overall coding efficiency space.

At the same time, the SADDC algorithm will intelligently slice and partition the remote control picture. If the picture is complex enough, the partition will be refined to 1000-2000 blocks, and then the blocks with changes in the picture will be recalculated, compressed and transmitted, while the blocks with no changes will be retained.

The more finely divided the blocks are, the more they can give play to the advantages of the previous visual saliency algorithm. After the combination of the two, the result is that the sunflower SADDC algorithm can intelligently judge the change range of the picture, which is similar to the energy-saving strategy adopted by some mobile phone screens.

In addition, if the configuration of the host is strong enough, the sunflower can further achieve a performance leap through hardware acceleration: by using the computing power of GPU to complete the operation and compression of the remote control picture "internally" in GPU, this strategy will greatly reduce the delay and greatly improve the frame rate of the picture online. Sunflower SADDC algorithm can increase the frame rate of the remote control picture to a maximum of 144 frames through this strategy. Can meet many high-end remote control needs.
