S. Voran and S. Wolf, "Proposed Framework for Subjective Audiovisual Testing,"
Contribution to ANSI Accredited Technical Subcommittee T1A1, Working Group T1A1.5,
Document Number T1A1.5/95-151, November 1993.
Abstract:
Working Group T1A1.5 is supporting ITU-T Study Group 12 in developing subjective audiovisual testing
methods under Question 22/12 which addresses audiovisual quality in multimedia services. A previous
contribution from Bellcore, T1A1.5/93-104, describes three basic tests that can be used to examine
how perceived audio quality and perceived video quality combine to create a perceived level of composite
audiovisual quality. These tests provide a logical and important first step toward understanding
the components of subjective audiovisual quality. The present contribution identifies two additional
tests that could supplement the three basic tests by providing information about the interactions between
perceived audio and video quality. The five resulting tests are summarized in tabular form. Key
ideas from this contribution could be integrated with those presented in T1A1.5/93-104 to create a
proposed U.S. Contribution to ITU-T Study Group 12.
