CTOnews.com news on November 30, Galaxy Kirin announced that the performance of secure cloud desktop products has recently been upgraded, using self-developed cloud video playback protocol to simplify the cloud desktop video playback process, and directly transmit the original video data to the client through a dedicated channel for decoding and playback. The server no longer needs to carry out complicated codec work, releases the computing performance of the server, and increases the number of concurrency of back-end users on the premise of ensuring picture quality. it greatly alleviates the risk of running computing resources in centralized video playback scenarios (such as distance education).

According to the official report, when playing videos with different resolutions (480p, 720p, 1080, 4K) of different coding standards (H264, H265), Kirin secure Cloud desktops with self-developed cloud video playback protocol significantly reduced the number of CPU cores on the server, with a maximum reduction of 97.90%. Among them, each 1-way 1080p24 video playback reduces the consumption of about 4 CPU cores, and each 1-way 4Kp24 video playback can reduce the consumption of 8 CPU cores, liberalize the resource restrictions for video playback, and allow users to play 4K videos at will.

Comparison of server CPU usage before and after optimization when playing videos on cloud desktops (test environment: ARM architecture server, Kirin desktop operating system) CTOnews.com learned that Galaxy Kirin secure cloud desktops also use placeholder global positioning and masking technology, which effectively solves the problem of screen interaction between cloud desktops and cloud videos, and greatly ensures the viewing experience of users. The cloud video playback protocol of Galaxy Kirin secure Cloud Desktop has been uniformly optimized at the bottom to achieve no perception of upper-layer applications-players and browsers do not need to adapt. At present, a number of mainstream players, including VLC, Kirin Audio and MPlayer, as well as a number of browsers have been tested, and the results have been improved.
