ITU-T P.1203.3 (12/2016)

对经可靠传送的渐进下载和自适应音视频流业务进行的基于参数比特流的质量评估 – 质量集成模块

ITU-T P.1203.3建议书为ITU-T P.1203建议书指定了质量集成模块。ITU-T建议书中的ITU-T P.1203系列指定了用于监测音频、视频和视频服务质量（例如自适应比特率视频流）的模块。相应的ITU-T工作项目被正式称为TCP多媒体流质量的参数型非入侵式评估（P.NATS）。ITU-T P.1203建议书的ITU-T P.1203.3部分可用于视频服务的性能和体验质量（QoE）监测，例如自适应比特率视频流。本建议书包含一份电子附件，附件中涉及第8.4款阐述的全部20个树。
