Abstract

A power control method for a set top box is disclosed. The method includes a first step for setting a time reserving and recording function for recording a broadcasting signal received from a set top box, a second step for recording the broadcasting signal in accordance with the time reserving and recording function of the first step, a third step for judging whether or not a synchronous signal is inputted into a broadcasting signal recording apparatus through a signal cable connected with the set top box during the operation of the second step, a fourth step for continuously performing a time reserving and recording function when it is judged that the synchronous signal is inputted into the broadcasting signal recording apparatus as a result of the third step, a fifth step for outputting a power code or channel code to the set top box when it is judged that the synchronous signal is not inputted into the broadcasting signal recording apparatus as a result of the third step, and a sixth step for performing the fourth step when the synchronous signal is inputted as a result of the judgment that the synchronous signal is inputted into the broadcasting signal recording apparatus after the fifth step, for thereby controlling the power of a set top box in accordance with whether there is a synchronous signal applied to the broadcasting signal recording apparatus when the power of the set top box is OFF.
