2019-04-20 11:30 - 12:15
Video Encoder is the key component of video cloud. It could run on different platforms. However, there are pros and cons on compression ratio, performance and cost for a single platform. The optimal solution could be achieved by combining different platforms into a heterogeneous one and utilizes all the advantages by encoder algorithms.
Video Codec is the field that relatively mature but rapid development constantly, new standard of video codec is endless, and new technology application is also changing quickly, the result of these factors is to inject young blood and energy into traditional field constantly, and it means that the engineers and researchers from the field need to learn new technology and develop new algorithm for meeting updated standard.2019 is important year for video codec, VVC standard is expected to be completed before long, more and more companies will invest in VVC that is being productized，the optimization and productization of AV1 and AVS3 will bring new scenery for industry. In addition, the devices with HDR screen and powerful GPU will become popular, and will also promote the popularization of a set of related technology and application.
