Abstract
A television signal receiving apparatus of the type in which when performing a picture in picture operation by receiving a plurality of picture signals compressed in band width by multiple sub-Nyquist sampling, a sub-channel signal is first subjected to a spatial interpolating process and combined with a main-channel signal. The still picture portion and moving picture portion of a first input signal are restored to a field offset sub-sampled first picture signal, and a second input signal is restored to a field offset sub-sampled picture signal, subjected to a size-reducing process by time base compression in the vertical and horizontal directions of the picture and delivered as a second picture signal of the form synchronized in phase with a given position of the first picture signal. The first and second picture signals are time-division multiplexed to deliver a third picture signal onto a picture screen.
