ESP™ Encoder Stress Pattern

ESP™ Encoder Stress Pattern

SRI’s ESP™ is a sophisticated video clip consisting of specialized and complex artificial test patterns that stress various aspects of processing to quickly reveal television encoder deficiencies. Its unique motion sequences allow users to visually evaluate and objectively compare the quality and performance of standard- and high-definition encoders.
