本文件规定了一种称为基本视频编码（EVC）的视频编码技术，该技术包含语法格式、语义和相关解码过程。解码过程旨在确保所有EVC解码器符合特定的功能组合，即配置文件、级别和工具集。任何产生与所述过程产生的相同裁剪解码输出图片的解码过程均被视为符合本文件的要求。 本文件旨在涵盖广泛的应用，包括但不限于数字存储媒体、电视广播和实时通信。

This document specifies a video coding technology known as essential video coding (EVC), which contains syntax format, semantics and an associated decoding process. The decoding process is designed to guarantee that all EVC decoders conform to a specified combination of capabilities known as the profile, level and toolset. Any decoding process that produces identical cropped decoded output pictures to those produced by the described process is considered to be in conformance with the requirements of this document. This document is designed to cover a wide range of application, including but not limited to digital storage media, television broadcasting and real-time communications.
