ANSI T1A1 Contribution T1A1.5/92-138, July 13, 1992.
Abstract: The motion difference images of the original and degraded video sequences is used to dynamically measure the Transmitted Frame Rate (TFR) and the Average Frame Rate (AFR) of a digital video system codec (coder-decoder). The TFR measurement algorithm gives the TFR spectrum, so that in cases where the TFR is adaptive, each TFR being used by the codec is obtained. The AFR measurement algorithm gives the average number of frames per second that were transmitted by the codec during a selected time interval. The TFR and AFR measurements presented here can be used for in-service as well as out-of-service testing of digital video systems.
