本文档概述了现有广泛使用的MPEG-2传输流规范的架构和结构变化，以适应通过MPEG-2传输流高效传输未压缩视频。它详细介绍了如何将未压缩的视频打包成基本流和PES流。它概述了在传输流上传输未压缩视频的封装结构，并依赖于现有的SMPTE ST 302、SMPTE ST 2038、ITU-T建议H.222.0/ISO/IEC 13818-1的PAT、PMT和PID管理结构。

This document outlines the architecture and structure of changes to the existing broadly used MPEG-2 transport stream specification to accommodate efficient transmission of uncompressed video over MPEG-2 transport stream. It details how uncompressed video is packed into an elementary stream and PES stream. It outlines an encapsulation structure for carrying uncompressed video over transport streams and relies on existing SMPTE ST 302, SMPTE ST 2038, ITU-T Recommendation H.222.0 / ISO/IEC 13818-1 for PAT, PMT and PID management structures.
