Use Class

A use class shares certain important aspects of specific use cases that are common to other use cases, allowing you to make video quality requirements generalizations between them. For example, all use cases have an analyst and a scene under observation. To identify a use class, the next step is to derive generalized aspects from the analyst’s intended use of the video (Use Characteristics — usage timeframe, discrimination level) and what is in the scene under observation (Scene Content — target size, motion, lighting level). See also, the Generalized Use Class Aspects topic for more information.[3]
