ABSTRACT:
The invention relates to a matrix wipe generator for television signals. With matrix switching, the television screen is divided into a plurality of blocks, and, if the screen originally contains the picture A, then picture B is switched into the blocks one at a time until all of the blocks, i.e., the whole screen, are filled with the picture B. The novel generator in accordance with the invention provides waveforms which give a Z-axis wipe effect, that is, the B picture appears to come into the screen from behind the A picture in each block.
