ABSTRACT:
A television signal receiving apparatus for a conventional television receiver capable of receiving a non-scrambled video signal and a related character signal inserted in a vertical blanking interval of the non-scrambled video signal comprises a tuner, a decoder, a video processor, a character generator, a controller, an input terminal and a scrambled signal decoder. The character generator 56 is set up at the television 2 and control signals for controlling this character generator 56 are inputted from the decoder 1. It is therefore not necessary to have a character generator on the side of the decoder 1 so that the construction of the system can be less complicated and the cost of the system can be reduced.
