| Abstract(in English) | Picture quality of bit-rate reduction coding is generally estimated by subjective assessment tests. To apply coding scheme to broadcasting, it is necessary to investigate a frequency distribution of picture characteristic in addition to subjective assessment. Although ITU-R proposes the 'criticality' which represents difficulty for coding, the definition of criticality hasn't be established yet. We have defined the criticality as output bits of a hybrid DCT encoder with a fixed quantizer, and evaluated correlation with picture quality measured by subjective assessment tests for some sequences. From the results of the criticality distribution of real TV programs, we evaluated the distortion degree of coded pictures in TV services. |
