Top 10 cutting-edge technologies for 2020 Double 11

Every second in the studio was a source of technical pride

The platform must synchronize the voice, picture and product information of the anchor to millions of consumers in a wide range of distribution within 1 second to ensure that the latter can get a consistent, real-time and high-level audio and video experience, as well as the credibility of commodity transactions (especially seckilling). At the same time, the same problem also exists in the large-scale real-time and highly parallel content e-commerce interaction represented by entering the live broadcast room, completing the purchase transaction, grabbing red envelope/point praise.

In order to further optimize consumer experience and reduce delay, Alibaba attaches great importance to investment in audio and video technology, including audio and video calling, low delay live broadcasting, S265 codec, real-time intelligent scheduling, self-learning participation system, etc. In particular, GRTN’s new generation of multimedia transmission network will be “applied for the first time in large scale in live streaming e-commerce with goods” in 2020 Double 11. The delay of live broadcast is reduced from 3-5 seconds in the past to less than 1 second. The extremely low interaction delay brings about qualitative improvement of live broadcast content and interactive experience, and forms a better interaction effect between consumers and anchors.
