For example, a television receiving card may be added to allow the computer to watch television. Such a television receiving card is inserted into a main board of a computer to display a television image on a monitor.

1 is a view showing a conventional television reception card.

Referring to FIG. 1, a conventional television reception card includes a tuner 4, an audio controller 6, an analog / digital converter (hereinafter referred to as an “A / D” converter) converter 2 and a controller 8. It is provided.

The tuner 4 receives a television signal from the outside. The tuner 4 receiving the television signal separates the audio signal and the video signal from the television signal. The audio signal separated by the tuner 4 is input to the audio controller 6. The audio controller 6 supplies an audio signal to a sound card (not shown) by removing noise and the like contained in the audio signal.

The video signal separated by the tuner 4 is supplied to the A / D converter 2. The A / D converter 2 converts the analog video signal supplied from the tuner 4 into a digital video signal and supplies it to the controller 8. The controller 8 removes the noise and the like contained in the digital video signal and supplies the video signal to a graphic card (not shown).

The sound card receiving the audio signal outputs a sound corresponding to the audio signal to the speaker. The graphics card receiving the video signal outputs an image corresponding to the video signal to the monitor.

The controller 8 receives various control signals from the user. For example, the user can input the television program that he / she wants to record to the controller 8. At this time, the user supplies the recording start time and the recording end time of the television program to the controller 8. The controller 8 which receives the recorded program from the user records the program by controlling the A / D converter 2 and the audio controller 6 at the time input by the user. At this time, the recorded program is stored in the hard disk of the computer.

However, such a conventional television receiving card cannot record a desired television program when the user is outside. Also, if the user wants to record, the computer must be turned on. In other words, when the user goes out, the user must turn on the computer to record the desired program. In addition, the computer stays on after the program is recorded until the user turns off the power.

In addition, when the television program timetable is changed due to a sudden event, the user may not record a desired program. For example, the user may go out after making a reservation recording of a program broadcast at 5 o'clock. At this time, if the program timetable is changed and a program to be broadcast at 5 o'clock is broadcasted at 6 o'clock, the user must change his or her recording setting. However, when the user is outside, the recording setting cannot be changed, and thus, the user cannot record the desired program.

It is therefore an object of the present invention to provide a system control apparatus and method for controlling using a telephone network and a television receiving card using the same.
