ABSTRACT:
An apparatus for performing programmed recording using broadcast program (BP) data in a two tuner system and a method therefor. The apparatus includes a switching portion which receives the output signal of a first tuner, the output signal of a second tuner, and an externally applied demodulated video signal, switches the input signals according to a switching control signal, and outputs a TV viewing signal, a BP data detecting signal, and a VCR recording signal. A BP data processor receives the BP data detecting signal, stores the BP data changed from the previously stored BP data during a BP data storing period and checks whether the BP data of the programmed recording is input during a discriminating BP data comparing period according to the BP data control signal. A TV signal processor receives, signal processes, and outputs the TV viewing signal to a monitor. A video recording processor receives the VCR recording signal and performs recording. A controller generates a switching control signal for determining multiple output signals by switching the input signals of the switching portion according to the selection of a user, a BP data control signal for defining a BP data comparing period and a BP data storing period, and a recording control signal for performing the recording only when the BP data set to be recorded is checked.
