PURPOSE:To prevent a video image desired to be viewed from being disturbed by character display by allowing a display position of channel information or the like displayed on a cathode ray tube screen to be moved optionally. CONSTITUTION:The display information such as channel display and sound volume display outputted from a control circuit 1 is fed respectively to a display control circuit 2 and a display position control circuit 3. A changeover circuit 4 is switched by control information inputted to the display position control circuit 3. The switching circuit 4 controls variably the oscillation frequency of an oscillation circuit 5 and the display position of characters displayed on the cathode ray tube 6 is changed by the frequency change. |
