Hybrid-NRe objective perceptual video quality measurement for HDTV and multimedia IP-based video services in the presence of encrypted bitstream data (Study Group 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.
