Development of HDTV High Speed CCD Camera System

Abstract

HDTV High Speed CCD Camera System was developed for telecasting sports event. It is composed of a 4-CCD camera head with 1.3Mpixel CCD arrays in a Alternative Dual-green pick up metod, 2.92Gbps optical transmitter, Slow Adaptor, 3 CCUs and 3 VTRs. Tripled speed signals are generated by CCD driver. Two CCD arrays for green, output 90fields every second alternately. Each of CCD arrays for blue and red, output 180field every second. Slow Adaptor converts these singals to standard signals and distributes to 3 CCUs which process signals digitally. Finally processed signals are recorded by 3 VTRs. Slow motion image is outputted by playing 3 VTRs at normal speed alternately. We report the configuration of the system, and its operation.
