Abstract

PURPOSE: To make it possible to share the display memory with two units of the picture receiver or to occupy the memory with ont unit of the picture receiver, by providing the means which varies the number of the scanning line to compose one line of the character to be siplayed on the picture receiver.
CONSTITUTION: The display memory is incorporated into display unit 20 to control picture receiver 30. In case the display memory features the memory equivalent to n-characters and the number of the display character is n/2, two units of the picture receiver are connected; while one unit of the picture receiver is connected when the character number is n respecitvely. Display memory 1 uses two units of RAM featuring mk-bits. Then the scanning lines comosing the character of the picture receiver are counted through counter 9 and counted in the line unit through counter 10. And when a coincidence is obtained with the fixed value, the signals sent from the character generator are set alternately to register 5 and 6, and video signal 14 is delivered alternately to two units of picture receiver 30 via mixer 7 and 8. With set of the O-value to counter 9, register 5 is selected to occupy the memory with one unit of the picture receiver
