Abstract

PURPOSE:To enable to observe a picture of the same character and graph with many TV receivers, by coverting chroma signals of character and graph received on a character broadcast receiver in such as a school into video signals of the standard system, by using an encoder. CONSTITUTION:A TV receiver 1 processes to output of a detection circuit 14 and picture normal video and outputs R, G, B outputs for character and graphic display from a character broadcast receiver 3 via an analog switching gate 16. The receiver 3 the R, G, B signals for display and a color burst signal Bu from received character broadcast signal by using a video signal VI and a synchronizing signal Sy outputted from the receiver 1. An encoder 5 consists of an NTSC encoder 28 using the signals R, G, B and the signals Bu, Sy and coverting them into the signals of the standard system, and an RF converter 29 constituting the RF signal of an arbitrary channel. The same characters and graphic pictures are displayed on many color TV receivers, by using cables connected to output connectors 30, 31 of the constitution like this.
