Abstract: Out-of-service measurements can be used to obtain a baseline video system delay. However, in many digital video systems, video delay is dynamic and dependent upon the scene content. This contribution describes an objective measure of video delay that can be made "in-service" and can thus track dynamic changes in the one-way video delay of a transmission channel. The metric correlates motion in the input and output video scene. A block diagram of a potential, real-time implementation is also given.
