Description

Method for operating master and slave televisions

The present invention relates to a method of operating a master and a slave television, and in particular, by controlling the slave television used by the children in the home equipped with one master television and one or more slave television through the master television so that children do not watch the television unconditionally. The present invention relates to a method of operating a master and slave television.

In general, the concept of child rock has been proposed to prevent children from watching TV indiscriminately. The child lock detects and analyzes the broadcast code included in the broadcast signal to limit the viewing by muting the television screen when the program is not suitable for children.

Referring to FIG. 1, the configuration of a conventional television having such a child lock function is as follows.

Conventional televisions include key input unit 10, microcomputer 20, tuner unit 30, video / audio signal processing unit 40, OSD unit 50, CRT 60, speaker 70, and broadcast code. The detector 80 is included.

The key input unit 10 includes a plurality of keys including a reservation selection key for selecting a reservation category, a movement key for moving a category, a confirmation key for finally selecting a category, and the like, to provide a key signal corresponding to a user's key operation. It outputs and transmits / receives a key signal carried on a predetermined infrared carrier using a remote controller that can be input at a remote location and applies it to the microcomputer 20 which will be described later.

The microcomputer 20 controls the overall operation of the television by selectively controlling the tuner 30, the video / audio signal processor 40, and the OSD unit 50 by the key signal from the key input unit 10. When a reservation selection key signal is applied from the key input unit 10, the user selects a desired category including all categories, such as news, drama, and sports, which are classified into category information included in the broadcast program information by the VPS. The category screen can be displayed by controlling the OSD unit 50, and the selected category is stored and controlled in the internal memory (not shown) based on the movement key signal and the confirmation key signal from the key input unit 10. FIG.

Meanwhile, the tuner unit 30 outputs a broadcast signal received by being tuned to a corresponding channel corresponding to the control of the microcomputer 20, and the video / audio signal processing unit 40 tunes under the control of the microcomputer 20. The broadcasting signal applied from the unit 30 is divided into a video and audio signal, and processed into a signal capable of display and output, respectively, and the video signal is output to the OSD unit 50 and the audio signal to the speaker 70, respectively.

The OSD unit 50 is an apparatus for processing OSD (on screen display) characters on a television screen. The OSD unit 50 reads a text signal corresponding to the control of the microcomputer 20 and displays the image / audio on a predetermined screen position. The synthesizer outputs a video signal or a blue-back signal applied from the signal processor 40.

In addition, the broadcast code detector 80 reads the broadcast program information inserted at a predetermined position within the vertical blanking period of the broadcast signal received from the tuner 30 under the control of the microcomputer 20 to read the microcomputer 20. By allowing the microcomputer to analyze it and perform the child lock function.

However, such a television having a child lock function has a child lock function when a microcomputer needs to perform a child lock function by analyzing broadcast program information inserted in a broadcast signal, or a user directly controls a corresponding program through a key input unit. Only if you do so will your child be restricted from watching television by muting the program. Therefore, if the broadcast program information embedded in the broadcast signal does not restrict the viewing of the child, the parent must perform the child lock function to restrict the viewing, and there are a large number of televisions in the home to directly If it is difficult to control the television, there is a problem in that children can not be prevented from watching television.

Accordingly, an object of the present invention to solve the problems of the prior art as described above is to control children's television by controlling the slave television used by their children in a home equipped with one master television and one or more slave televisions. It is to provide a method of operating a master and slave television that can be prevented from watching.
