The evolution of HDTV in the work of the CCIR

The development of television system standards in the CIR (International Radio Consultative Committee) is reviewed. Background and results of the extraordinary meeting on high-definition television (HDTV) of CCIR Study Group II are presented. The arguments for a global studio standard for HDTV are examined as are the proposals for achieving this objective. The evolution toward digital systems and the preparation of emission/transmission standards is summarized. Cost, size, weight, and time frame are seen to be major constraints.<
