Abstract
Referential measurement tools that are used to measure video quality are typically very sensitive to synchronization and scaling issues that occur when video captured at a recipient device is out of synchronization with a source video and/or is scaled, e.g., to a different aspect ratio. When the captured video has such differences from the source video, conventional referential measurement techniques produce erroneous results. This disclosure describes techniques to process captured video to account for scaling effects and to synchronize captured video with source video. Referential measurement can then be performed with greater accuracy. A synchronization measurement technique is also described.
