ABSTRACT:
Horizontally compressed video signals sensed in film scanning are transmitted at a slower rate for time expansion while the beginning of the transmission of each line is electronically delayed by an amount, constant at least for each picture field, which determines the centering of the narrower picture to be transmitted by television. This processing can be done before digitalization of the picture for storage, in the read-out of semiconductor sensors or it can be done after digitalization either before or after picture storing or partly before or partly after. In a preferred form a complete Cinemascope frame is stored in the picture store and both the time expansion and the picture shift are provided in the read-out of the picture store.
