Abstract: Presents results from the analysis of variance (ANOVA) of the subjective opinion scores for the T1A1 subjective video experiment that contained 625 mean opinion scores (25 test scenes passed through 25 different video transmission systems that ranged in bit rate from 64 kb/sec to 45 Mb/sec). This contribution includes the analysis of the three teams (green, red, and orange) for two of the three laboratories involved in the testing. The analysis was performed as discussed in contribution T1A1.5/94-128 ("Methods for Analysis of Inter-laboratory Video Performance Standard Subjective Test Data"). The ANOVAs showed that all main effects and interactions were significant for all teams within the two laboratories.
