Where have we come from, and where are we going? (digital TV studio)

Examines the route to the development of the all digital TV studio. The earliest digital video equipment were experimental and prototype ADCs. This was followed by a video tape time-base corrector. 1976 saw the introduction of frame store synchronizers based on RAM, and digital video effects in the form of position manipulation and reduced picture size. As a result of current studies into Improved (IDTV), High (HDTV) and Enhanced (EDTV) systems, intermediate standards may be needed due to the frequency brickwall inherent with the current 601 specification.<>
