a) Approaches to the specification of a studio standard, HDTV have been in the context of present operations in 525/59.94 and 625/50: i.e., operations in the studio conform to the specifications for transmission and broadcast. The studio standard with its implication of no systems transform, therefore, might be described also as one of the distribution standards - expected to be one of the inputs to display, and to be evaluated by subjective judgment of the display.

b) As employed by CCIR Rep 801-4 and its annexes, the term studio standard loosely embraces everything from image capture through distribution. To illustrate the interpretation by examples from the document. (a) Sec 1, Introduction: A single standard could be beneficial to program producers as well as broadcasting organizations and viewers. (b) Sec 2, Technical Matters: This entire section is concerned with defining the system by reference to the subjective, visual appraisal of the final display. (c) Annex II, entitled Parameter Values for Signal Generation in HDTV Studios and For International Exchange of HDTV Programs. (d) Sec 1e explains that the advantages of a single HDTV worldwide standard includes lower HDTV equipment costs for broadcasters and viewers, easier exchange of programs and technical information, and encouragement to the ideal of international solutions to common technical problems. These concepts of a studio standard accordingly address only a small part of what the SMPTE Committee on Hybrid Technology considers production.
