Standard Video Sequences

These standards provide sets of video test scenes in digital format that can be used for subjective and objective testing of digital video systems. Standardized test scenes are important because video images with little detail or motion may retain their quality during digital compression and transmission, while images with extensive detail or rapid motion may become significantly impaired. Having standardized test scenes gives users the ability to directly compare the performance of two or more systems.
