ITU-T J.343.1-2014 为在加密的比特流数据中的高清晰度电视(HDTV )和基于多媒体网际协议(IP)视频服务的混合非客观感知的视频质量测量(研究组9)

Recommendation ITU-T J.343.1 provides hybrid no-reference encrypted (Hybrid-NRe) objective perceptual video quality measurement methods for HDTV and multimedia when encrypted bitstream data are available. The following are example applications that can use this Recommendation:? potentially real-time, in-service quality monitoring at the headend;? video television streams over cable/IPTV networks including those transmitted over the Internet using Internet protocol;? video quality monitoring at the receiver when encrypted bitstream data are available;? video quality monitoring at measurement nodes located between point of transmission andpoint of reception when encrypted bitstream data are available;? quality measurement for monitoring of a transmission system that utilizes video compression and decompression techniques,either a single pass or a concatenation of such techniques;? lab testing of video transmission systems.This Recommendation includes an electronic attachment containing test vectors, including videosequences,bitstream files and predicted objective model scores.
