A picture-in-picture television receiver is so arranged that the compression ratio of a sub-picture discrimination character (4) displayed on a sub-picture screen (Ss) relative to a main picture discrimination character (12) displayed on a main picture screen (Sm) is selected to be smaller than that of the sub-picture (Ss) relative to the main picture (Sm), whereby the sub-picture discrimination character (4) is displayed in a relatively large, easier-to-see form. |
