The mixer 17 mixes the R, And a CRT driving unit for driving the CRT to display an image.

When another viewer in the vicinity uses a television receiver having such a configuration to view a television broadcast signal of a desired channel by a specific viewer, when a desired television broadcast signal is converted into a desired television broadcast signal by the other viewer, It is often the case that unintentional accidents such as a conflict between a specific viewer and another viewer arise.

Therefore, it is an object of the present invention to provide a method and apparatus for a television receiver, which is capable of setting a monopoly channel and a monopoly time for a specific viewer and switching to a monopoly channel in which a reception channel is set when the monopoly time is set, The channel switching method comprising the steps of: (a) receiving a broadcast signal of a monopoly channel;

According to another aspect of the present invention, there is provided a method of monopolizing a channel for a composite video apparatus, the method comprising: a first step of storing data of an exclusive channel and an exclusive time input and counting a current time; A second step of comparing the current time counted in the first step with the stored proprietary time; A third step of switching the channel to the exclusive channel stored in the first step and determining whether the channel switching data is input when the current time and the exclusive time are the same as the comparison result in the second step; A fourth step of determining whether the current time is the exclusive time stored in the first step when the channel switching data is input in the third step; And a fifth step of switching to a channel according to the input channel switching data when the current time is not the exclusive time, without switching the channel when the current time is the exclusive time in the fourth step.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

1, the control unit 10 includes a key input unit (not shown) and a remote control device 7 (not shown). In the first embodiment, And the data corresponding to the exclusive time are input, it is stored in the memory and the time is counted so as to operate as shown in the signal flow diagram shown in FIG.

A channel exclusive method of a composite video apparatus of the present invention applied to a television receiver having the above-described configuration will be described in detail with reference to a signal flow chart shown in FIG.

In order to monopolize the channel of the composite video device employing the method according to the present invention for a predetermined time, when the user sets the exclusive channel reservation and exclusive time by operating the key input unit or the remote control device 7 in step S1 of FIG. 2 , The controller 10 stores the data input in the step S2, that is, the data of the inputted exclusive channel and the exclusive time in the memory.

When the storage of data is completed in step S2, the controller 10 counts the current time in step S3 and determines whether the current time counted in step S4 is the exclusive time of the set exclusive mode.

If it is not the exclusive time of the exclusive mode set in step S4, the control unit 10 returns to step S3 to count the current time continuously and determine whether the counted current time is the exclusive time of the set exclusive mode .

If the current time counted in step S4 is the reservation exclusive time of the exclusive mode, the control unit 10 switches to the exclusive channel in which the reception channel of the television receiver is set in step S5, and in step S6, And displays the television broadcast signal of the exclusive channel.

In step S7, it is determined whether or not the channel switching data is inputted. When the channel switching data is inputted, the time of the exclusive mode set at step S8 .

If it is determined in step S8 that the current time is the time of the exclusive mode, the control unit 10 ignores the input channel switching data, returns to step S6, and displays the television broadcasting signal of the exclusive channel do.

If it is determined in step S8 that the current time is not the time of the exclusive mode, the receiving channel of the television receiver is switched to the channel corresponding to the input channel switching data in step S9, and the television broadcasting signal of the switched channel is displayed do.

As described above, according to the present invention, the exclusive channel and the exclusive time are set, and when the exclusive time is set, the exclusive channel is automatically switched to the exclusive channel. In addition, The television broadcast signal of the set exclusive channel is continuously received and displayed without switching the channel even when the channel switching data is input, so that the monopolized channel set for the set exclusive time can be monopolized and the television broadcasting signal can be viewed.
