Problems of Upward and Downward Compatibility in Multichannel Stereo Systems

Authors: Gerzon, Michael A.

AES Convention 93 · Paper 3404 · October 1992

Abstract

This paper reviews, in the context of multispeaker stereo systems using up to five loudspeakers, the problem of determining the best upward and downward compatibility matrixing for other reproduction systems. Published HDTV compatibility matrices are shown to take an inadequate account of 3 factors: 1) psychoacoustic quality of localization, 2) the effect of using different panpot laws, and 3) the problem of cascadability, i.e. the losses caused by repeated conversions along a long production chain between different reproduction modes.
