Abstract

This monograph summarizes the fundamental and practical aspects of a suppressed-frame 35mm, telerecording channel designed and constructed by the BBC Engineering Research Department primarly to provide additional telerecording facilities for use in connection with the Coronation. In view of the comparatively short time which was available for the designs and constructions of this channel, it was decided that any method of recording which required the development of new mechanisims and optics should be avoided. Tests were therefore made in order determine the picture quality which could be obtained using a high grade television monitor and the commercially-avaliable 35mm cine camera. The results of the tests indicated that the construction of an apparatus of this type would be amply justified.
