本文概述了用于超越HEVC功能的视频压缩的联合探索模型（JEM）的编码算法，该模型由ITU-T视频编码专家组（VCEG）和ISO/IEC运动图像专家组（MPEG）的联合视频探索小组（JVET）开发。JEM开发和实验的目标是提供证据，证明编码效率比高效视频编码（HEVC）标准有足够的提高，这将证明需要一个压缩能力明显超过HEVC的新视频编码标准。JEM的开发提供了以可验证和协作的方式进行研究的能力，并导致了开发新的通用视频编码（VVC）标准的项目的启动。对于大多数测试的高分辨率视频内容，客观度量增益超过30%，这些内容代表了当前要求很高的新应用，而使用人类观察员进行的主观测试显示出更多的好处。
This paper provides an overview of the coding algorithms of the Joint Exploration Model (JEM) for video compression with capability beyond HEVC, which was developed by the Joint Video Exploration Team (JVET) of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). The goal of the JEM development and experimentation was to provide evidence that sufficient coding efficiency improvement over the High Efficiency Video Coding (HEVC) standard can be achieved, which would justify the need for a new video coding standard with a compression capability significantly exceeding that of HEVC. The development of the JEM provided an ability to conduct studies toward that goal in a verifiable and collaborative manner and led to the launching of the project to develop the new Versatile Video Coding (VVC) standard. Objective metric gains exceeding 30% were measured for most of the tested high-resolution video content that represents current demanding new applications, and subjective testing using human observers showed even more benefit.
