Summary

Recommendation ITU-T J.343.2 provides hybrid no reference (Hybrid-NR) objective perceptual video quality measurement methods for HDTV and multimedia when non-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 non-encrypted bitstream data are available;

������������ video quality monitoring at measurement nodes located between point of transmission and point of reception when non-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 video sequences, bitstream files and predicted objective model scores.
