On October 29, Tencent Cloud announced the official launch of 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 needs of cloud gaming with low latency and high throughput. Under the same image quality, it can achieve a 15% reduction in bandwidth usage. If it is at the same bandwidth Under the conditions, the picture quality can be greatly improved.
Although bandwidth has continued to increase in recent years, the demand for high-quality video transmission has become stronger. Video coding compression technology is the main means of transmitting high-quality video under limited bandwidth by compressing the amount of original video data. Especially with the rise of cloud games, how to better solve the contradiction between bandwidth, image quality and real-time communication has become the focus of the industry. However, the current encoders on the market usually meet the requirements of real-time encoding. Coding tools and algorithms do a lot of cropping and simplification, which ultimately leads to low compression efficiency.
In order to solve this pain point, Tencent Cloud’s first self-developed H265 hardware encoder Yaochi V500 has improved the compression efficiency of the real-time encoder to a new level.
In terms of algorithm, Yaochi V500 fully implements all mainstream coding tools such as high-precision motion search, full-rate-distortion optimization, efficient adaptive quantization, and integrates leading technologies such as Tencent Cloud software encoder rate control, with superior compression efficiency; In terms of hardware design, technologies such as flexible multi-core expansion architecture, high-performance encoding pipeline, hierarchical memory layout, etc., have well met the requirements of high throughput, low latency, and real-time.
According to the performance evaluation of the mainstream encoders on the market by the third-party organization MSU, the compression efficiency of Yaochi V500 in real-time scenarios is significantly ahead of other encoders tested.
According to the actual measurement of the project, Yaochi V500 can not only meet the requirements of mobile game cloud game experience, but also reduce the bandwidth by 15% compared with mainstream solutions in the market under the same image quality. If it is under the same bandwidth condition, the improvement effect on image quality is obvious (as shown in the figure below) The details of the floor texture shown are richer and more complete).
In addition to cloud games, Tencent Yunyaochi V500 hardware encoder is also suitable for high-definition live broadcast scenes. The live broadcast scene is different from the cloud game scene. The live broadcast is not sensitive to delay requirements, so there is more room for algorithm optimization. After actual measurement, the compression efficiency advantage of the Yaochi V500 in the live broadcast scene can be increased to 30%, and the image quality is improved more obviously under the same bandwidth.
"With the advent of the 5G era, ultra-high-definition streaming media applications such as cloud games and 4K/8K HD live broadcasts are growing rapidly. Video encoding is a key technology that determines experience and cost. With years of accumulation in encoding and hardware, we have everything We are confident that the Yaochi series will provide the industry with better video coding solutions and help the industry develop faster.” said Lou Jibing, vice president of Tencent Cloud.
It is understood that Tencent Cloud’s self-developed H265 hardware encoder Yaochi V500 will be the first to be used in Tencent’s self-developed cloud gaming, live broadcast and other ultra-high-definition streaming services, and will gradually be opened to customers on the cloud.
