本文件规定了一套测试和程序，旨在表明编码器或解码器是否符合基本视频编码（EVC），其中包含测试和参考软件，用于验证比特流和解码器是否符合ISO/IEC？23094-1中规定的规范性要求。如果编码器生成的比特流符合ISO/IEC？23094-1，则编码器可以声明符合ISO/IEC？23094-1。编码比特流和解码器的特性在ISO/IEC？23094-1中定义。解码器特性定义了应用解码过程的属性和能力。解码器的功能指定解码器可以解码和重建哪些比特流。 如果比特流的特征在指定的解码器能力范围内，则该比特流可以由解码器解码。

This document specifies a set of tests and procedures designed to indicate whether encoders or decoders essential video coding (EVC), which contains tests and a reference software designed to verify whether bitstreams and decoders meet normative requirements specified in ISO/IEC？23094-1. An encoder can claim conformance to ISO/IEC？23094-1 if the bitstreams that it generates are conforming bitstreams. Characteristics of coded bitstreams and decoders are defined in ISO/IEC？23094-1. Decoder characteristics define the properties and capabilities of the applied decoding process. The capabilities of a decoder specify which bitstreams the decoder can decode and reconstruct. A bitstream can be decoded by a decoder if the characteristics of the bitstream are within the specified decoder capabilities.
