METHOD FOR EXCHANGING PART OF GIVEN TELEVISION PROGRAM WITH PART OF SELECTED INDIVISIONALLY TRANSMITTED PROGRAM FOR SPECIFIG RECEIVER BY REMOTE CONTROL, HOME TERMINAL EQUIPMENT FOR EXECUTING THE SAME METHOD AND OPERATING METHOD OF THE SAME HOME TERMINAL EQUIPMENT

摘要

PURPOSE: To convert a part of certain one of television programs to a part of an individual transmission program for a selected specific viewer by transmitting a two-phase modulated start code to a picture scanning line on the outside of a television picture which can be seen on the screen. CONSTITUTION: A first program is first received by a first tuner 24, and a second tuner 25 is switched between data reception and the retrieval process, where a channel of a controlled video recorder is confirmed, continuously with a prescribed switching period. When cross fading is started and the start code is emitted, a start code signal is received by a decoding circuit, and switching from one tuner to the other is started. Then, the output of the second tuner which receives a faded-in spot commercial is given on the screen. The start code is put on picture information existing in the lower end of a transmitted television picture. Thus, it can be transmitted in a frame of an ordinary composite color picture signal (FBAS signal).
