Topic：Recent trends in live cloud video transcoding（实时云视频转码的未来）

Video Transcoding represents massive cloud work loads which are growing at 50% CAGR. This talk will discuss the modern trend to use programmable hardware acceleration (Xilinx FPGA’s) to replace Intel Xeon CPU's. Twitch announced last year they are using FPGA acceleration in their data centers. Today many public clouds including AWS, Alibaba, Huawei etc. have FPGA instances which can be rented by the hour. This talk will compare the two major metrics for live cloud video transcoding: Total Cost of Ownership (TCO) for encoding and bandwidth reduction based on better compression.

（视频转码占据使用了大量的云端资源，年复合增长率50%。本分享将讨论时下的云转码趋势——通过Xilinx FPGA替代Intel Xeon处理器。去年，Twitch宣布在其数据中心中使用了FPGA加速方案。如今，AWS、阿里云和华为云都提供了FPGA实例，并可按小时出租。本次分享还将对比两种硬件转码方案在TCO和压缩效率及带来的带宽节省方面的差异。）

Topic：Seismic shifts in the Codec Landscape（Codec世界的新蓝图）

Do you know what MPEG-5 part 2 (LCEVC) is? And EVC? VVC, AV1, AVS2? Anyone getting an acronym headache? Alongside VP9 and HEVC these next-generation standards are all vying to be the successor to h.264, but will there ever be a single successor again? With the single-standard single-resolution media delivery chain definitely broken, operators and service providers are looking for the best tool for the job in every part of their ecosystem, to improve services and reduce costs. In most cases, codec complexity is increasing all of the time, so which of these new standards will be feasible to deploy for live services in the near-future? Moreover, what encoding infrastructure can deliver the higher quality promised at sustainable costs?In this presentation, compression experts V-Nova will discuss these issues and provide practical guidance to anyone deploying or upgrading services whilst also revealing some of the secrets of the latest standard in the MPEG family, LCEVC, a low-complexity enhancement for all codecs, even non-MPEG ones.

（你知道MPEG-5 part 2 (LCEVC)吗？EVC，VVC，AV1，AVS等为何物？我们熟知的VP9和HEVC被认为是H.264有力竞争者，然而Codec市场还将一枝独秀吗？不会的，单一标准、单一方案的传播链条已经破裂，多媒体运营商寻找符合各自生态需求的方案，以求更高的服务和更低的成本。大多数情况下，Codec的复杂度正在增长，那么在不久的将来，选择哪些Codec更加务实？哪些视频编码基础方案实现质量和成本的平衡？在本次分享中，视频压缩专家V-Nova会讨论这些问题，并提供可行的部署和升级建议。同时，还会透露一些关于MPEG LCEVC的最新信息，它是一种低复杂度的增强视频编码，可以是任何Codec，甚至不是MPEG标准中的一个。）
