- This standard specifies a collection of test scenes that have been used for subjective assessment and may be used in future objective assessment of Video Teleconferencing/Video Telephony (VTC/VT). The scenes represent limited examples of the content that may be found in VTC/VT usage. The collection does not constitute a balanced set of scenes in any knonw way, and use of the scenes to determine an overall performance assessmentg is beyond the scope of this standard.Other test scenes may be used in video performance assessment, but their specification is also beyond the scope at this time. The test scense identified within this standard are applied at the analog input interface shown in figure 1. Service channel interfaces (analog input and analog output) are between VTC/VT transmission service providers and end-users.
