And a menu key (not shown) for changing and selecting various menus. It also has an EPG display key (not shown) for displaying the EPG for the program of each channel.

Here, the channel information displayed in the EPG includes a broadcast station name, channel number, broadcast time, program genre, program detail information, program name, and the like.

The controller 20 generally controls the channel changing apparatus of the digital television according to the embodiment of the present invention. When the user inputs a channel change key provided in the key input unit 90, the controller 20 checks whether a channel change mode for each program genre is selected to change the channel according to the current program genre.

At this time, if the channel change mode by program genre is set, check whether the channel change according to the priority is selected, and if the channel change according to the priority is selected, it is included in each program genre in the order of the program genre of the above priority. The tuner 10 is used to change the channel.

On the other hand, if the channel change according to the priority is not selected, the channel is changed to the channel currently selected, that is, the channel of the same program genre as the channel currently being viewed by the user.

Here, the channel change according to the program genre is continuously changed for each program genre unless the user releases the channel change mode for each program genre.

A channel changing method of a digital television according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3.

In this case, regardless of the channel number of the current channel, the channel is changed in order of fast channel number according to the priority, or the channel is changed to the channel number after the channel number of the current channel.

For example, if the currently selected program genre is news, art or drama, the priority is news, art or drama, and the program genre is news, channels '4', '8' and '9' If the artist channel is '2', '5', '7' channel and the program genre is drama '3', '6', '11' channel is explained as follows. .

That is, when changing the channel in the order of fast channel number according to the priority regardless of the channel number of the current channel, if the channel number of the channel currently being viewed is 6, the news channel having the highest program genre has priority. '4', '8', and '9' channels are changed in order, and the next highest priority genre of art channels is changed to '2', '5', and '7' channels. The drama channel, which is the program genre of priority, is changed in the order of '3', '6', and '11'. Therefore, whenever the channel change key is input, the channel is in the order of '4', '8', '9', '2', '5', '7', '3', '6', '11'. Is changed.

 When changing the channel to the channel number after the channel number of the current channel, if the channel number of the channel currently being watched is channel 6, the news channel with the highest program genre is '8', '9', '4'. 'The channel number is changed in order of channel number one, the art channel with the next priority program order is changed to' 2 ',' 5 ',' 7 'channel order, and the drama channel with program level with the last priority level is' 3'. It is changed in order of ',' 6 ',' 11 'channel. Accordingly, the channel is changed in the order of '8', '9', '4', '2', '5', '7', '3', '6', and '11'.

On the other hand, it is checked whether the channel change according to the priority is selected (S31), and if the channel change according to the priority is not selected, it is checked whether the channel currently being viewed is included in the selected program genre. At this time, if the channel currently being viewed is a channel broadcasting a program of the same genre as the selected program genre, the channel broadcasting the same genre is checked (S33) and a channel broadcasting a program of the same genre as the program genre of the currently watching channel is checked. The channel number is changed in order (S34).

However, if at least two or more program genres are selected and the priority for these program genres is not set, the channels of the same genre as the program genre of the channel currently being watched are sequentially changed in order of channel number. Channels corresponding to each program genre are sequentially changed in order of channel number according to the order in which the program genre is set.

On the other hand, by checking whether the program genre of the channel currently being viewed is included in the selected program genre, if the currently selected channel is not the channel of the selected program genre, the channel is changed to a channel that broadcasts a program corresponding to the selected program genre. In this case, the channel changing method between channels for broadcasting a program of the same program genre as the selected program genre is as described above.

However, the technical scope of the present invention is not limited thereto, and will include changing channels in various ways for each program genre.
