Abstract
PURPOSE:To discriminate the receiving status of a character signal at a glance in case of the selection of a program by displaying the number of programs including the character signal with a color bar when the character signal superposed over the period of plural horizontal scanning is to be received. CONSTITUTION:When a multiplex information program to be received is specified by a program selecting circuit 12, a write/read control circuit 9 compares the specified program code signal with the received program number signal and, when both signals are coincident to each other, a page of the transmitted pattern data of the spacified program is written in a main memory 10 to store the data. The pattern data stored in the main memory 10 is read out synchronously with the laster scanning of a cathode-ray tube (CRT) 13 and a page of the multiplex information of the specified program is displayed on the picture under the stationary status for a fixed period. In this case, a display control circuit 14 outputs a bar signal classified with a color according to each sacnning to display the number of program to be received with a color bar.
