Abstract

PURPOSE: To obtain detailed explanation relating to content of broadcast by synthesizing each TV signal of plural channels in multiple so as to be displayed on a screen of a reception terminal equipment and sending each simultaneously.
CONSTITUTION: A transmission signal is converted into a digital signal by an A/D converter section 11 and number of scanning lines of the signal is decreased to the scanning line number to be displayed on a television pattern display section 21 by a scanning line compression section 12 and synthesized as a digital picture signal by a multiple picture synthesis section 13. In this case, a synchronizing signal is outputted from an internal synchronizing signal generating section 14 to a multiple picture synthesis section 13, received character information is generated by a character generating section 15 and synthesized with a synthesis picture signal from the multiple picture synthesis section 13. Then a scroll control section 17 scrolls only character information and a digital synthesis signal from the synthesis section 16 is converted into a base band NTSC signal by a D/A converter section and the result is sent to a CATV line and received patterns 22a-22l are displayed on a multiple synthesis screen section 22 of the television pattern display section 21. Thus, more detailed information guidance is implemented.
