Abstract
A picture-in-picture television receiver is so arranged that the compression ratio of a sub-picture discrimination character displayed on a sub-picture screen relative to a main picture discrimination character is selected to be smaller than that of the sub-picture relative to the main picture, whereby the sub-picture discrimination character is displayed relatively large in an easier-to-see form.
