In response to data supplied from a system controller, a display microcomputer of a television receiver produces a display in a sub-screen of the cathode-ray tube of a main menu corresponding to the numerous operating functions of which the television receiver is capable. Some of these functions include a picture-in-picture function, a satellite broadcast receiving function, and a picture-recording reservation function. When a user of the television receiver selects an item on the main menu corresponding to the picture-in-picture function by using a remote controller, the system controller controls an audio video switch, the picture-in-picture circuit, and a display microcomputer to provide two picture-in-picture sub-screens displayed simultaneously. One sub-screen contains a sub-screen menu to enable the user to set parameters relative to the picture displayed in the other sub-screen. <IMAGE> |
