ABSTRACT:
An apparatus for selecting one of a number of television channels is operable to be set in a mode whereby an array of miniature pictures corresponding to the respective channels is displayed, with each channel being sequentially selected for a predetermined interval during which image data for the selected channel are repetitively written into one of a set of regions (42 to 50) of a one-field memory, with the entire memory contents being continuously and repetitively read out, whereby the picture for the selected channel appears as a moving picture while those of the other channels are static. The apparatus can then be set in a normal operating mode, with the channel selected at the time of mode changeover being thereafter held fixedly selected and a normal display picture produced.
