Abstract

PURPOSE:To avoid a broadcast screen from being masked with characters and characters from being difficult to see, by setting selectively a mode picturing character screen, mode picturing broadcast screen and mode picturing the two at the same time, and increasing the number of scanning lines. CONSTITUTION:In case of a TV mode, a video signal is inputted to a line conversion circuit 8, memories 11, 12 alternately writes video signal for 1 H's share and twice readout is made in the speed of H/2. The read-out video signal is applied to a cathode ray tube 22 in horizontal deflection in 2 fH. In case of a character code, a signal having the character information decoded at a character decoder 9 is applied to the cathode ray tube 22. Next, in case of two-screen mode, a signal from a line conversion circuit and a signal from a character decoder 9 are switched at every H/2 at a switch circuit 20 and applied to the cathode ray tube 22 in horizontal deflection in fH, and a TV screen is displayed at the first half of the same scanning line and a character screen is displayed at the latter half.
