Abstract
A circuit and method for performing a specific function at a receiving side if a video signal in which a code is inserted is transmitted. A transmitting side of a broadcasting system transmits a video signal in which a given code relating to a specific function like a time correction or a program reservation of a receiving side is inserted. The receiving side detects the code and then transmits the detected code to a circuit for performing the specific function by inputting a one touch key. Without the key input of a user, the corresponding time correction function is automatically controlled according to the code detected from a received video signal.
