On October 29, Tencent Cloud announced officially launched the H265 hardware encoder Yaochi V500. It is understood that as Tencent Cloud's first self-developed H265 hardware encoder, Yaochi V500 can fully meet the demand for cloud games, in the same picture quality, can achieve 15% of bandwidth, if it is equivalent to bandwidth Under conditions, the picture quality can be greatly improved.
Although the bandwidth in recent years is increasing, the demand for high-quality video spread is also more strong, video encoding compression technology is the main means of transmitting high-quality video under limited bandwidth by compressing the amount of raw video data. Especially with the rise of cloud games, how to better solve the contradiction between bandwidth, picture quality and real-time communication into the focus of industry concerns, however, the encoder on the current market will usually be in order to meet real-time coding requirements. The encoding tool and algorithm do a lot of cropping and simplification, eventually leading to low compression efficiency.
In order to solve this pain point, Tencent Cloud's first self-developed H265 hardware encoder Yaochi V500, raising the compression efficiency of real-time encoders to a new level.
In the algorithm, Yaochi V500 fully implements all mainstream encoding tools such as high-precision motion search, full range distortion optimization, efficient self-efficiency quantization, and combines the leading technology of Tencent Cloud Software Encoder Code Rate Control and Its Compression Efficiency; In hardware design, through flexible multi-core extension architecture, high-performance encoded pipeline, hierarchical Memory layout, etc., high-throughput, low-delay and real-time requirements.
According to the third-party mechanism MSU, the performance evaluation of the mainstream encoder on the market, the Yaochi V500 is under real-time scene, and the compression efficiency leads a leading encoder.

The project is measured, but the Yaochi V500 can not only meet the requirements of the mobile game cloud game, but also reduce 15% bandwidth compared to the mainstream program in the same picture quality. If it is under the same bandwidth conditions, the improvement effect on the image quality is obvious (as shown below The details of the floor texture presentation are more complete and more complete).

In addition to cloud games, Tencent Yao Yao V500 hardware encoder is also suitable for high-definition live broadcast scenarios. Live broadcast scenes are different from cloud game scenes, live broadcast is not sensitive to delay requirements, so the algorithm optimizes the space. It is measured that the advantages of Yaochi V500 compressed efficiency under live scenes can be increased to 30%, and the image quality in the same bandwidth is more pronounced.

"With the arrival of the 5G era, the cloud game, 4K / 8K high-definition live broadcast is more and more increased, video coding is a key technique for determining experience and cost. With many years of accumulation in coding and hardware, we have completely Confidence allows the Yaochi series to provide a better video coding solution for the industry to help the industry will develop faster. "Tencent Cloud Vice President Yan Ji Bing said.
It is understood that Tencent Yun Shengyan H265 hardware encoder Yaochi V500 will take the lead in using ultra HD streaming media services such as Tencent's self-developed cloud game, live broadcast, etc., will gradually open to customers on the cloud.
