The receiver 101 receives a broadcast signal transmitted from a broadcast center. The broadcast signal includes video, audio, and data (subtitles, UI, etc.). The receiver 101 receives a broadcast signal by converting a frequency according to the channel switch signal received from the channel switch unit 105. In addition, the receiver 101 receives an electronic program guide (EPG) separate from the broadcast signal. The electronic program guide may be received in a channel separate from the broadcast channel or may be received through a specific broadcast channel.

The signal processor 102 demodulates and decodes the broadcast signal received by the receiver 101 and displays the same on the display unit 103, and the electronic program guide demodulates and decodes the signal to store in the storage unit 106.

The display unit 103 includes a display device such as a liquid crystal display (LCD).

The input unit 104 receives a user input for operating the digital broadcast reception device. The input unit 104 may include a plurality of key buttons, may include a touch pad, and may include a means for receiving an input by a remote controller. In the present invention, the input unit 104 receives an input for channel switching from the user. The input for channel switching may include an input for outputting a broadcast channel list, an input for selecting one of the lists listed in the broadcast channel list (for example, inputting a confirmation button, a one-click input or a double-click input on the touch pad). , Switching input (e.g., direction key) to the next broadcast channel.

The channel switching unit 105 receives an input signal for channel switching through the input unit 104 and performs processing accordingly. When receiving an input for outputting the broadcast channel list, the user can view the broadcast channel list display unit 103 for viewing, and when receiving an input for selecting any one of the lists listed in the broadcast channel list, the channel switching signal accordingly. Is transmitted to the receiver 101 to display the program of the broadcast channel selected by the user. Alternatively, when the channel switching unit 105 receives a switching input to the next broadcasting channel, the channel switching signal of the current broadcasting channel to the next broadcasting channel is transmitted to the receiving unit 101 so that the program of the next broadcasting channel is displayed. .

The channel switching unit 105, in the process of switching the broadcasting channel according to the channel switching input signal input through the input unit 104, selectively broadcast channels selected by the user in the storage unit 106 according to the channel switching input signal. Broadcast information is extracted and displayed on the display unit (103). When the user clicks on any one of the lists listed in the broadcast channel list, the broadcast information is extracted and displayed when the user double-clicks without extracting the broadcast information of the selected broadcast channel. Alternatively, when the user presses a predetermined direction key in any of the lists listed in the broadcast channel list, the broadcast information of the corresponding broadcast channel is extracted and displayed. Alternatively, if the duration of the channel switching input signal is checked, the broadcasting information of the broadcasting channel to be switched is not extracted when the duration of the channel switching input signal is longer than the threshold time. Extracted from 106 and displayed on the display unit 103.

The channel switching unit 105 displays the broadcast information on the display unit 103 for a predetermined time when displaying the broadcast information of the broadcast channel on the display unit 103. For example, broadcast information is displayed until signal processing of the broadcast channel to be switched is completed, or broadcast information of the broadcast channel to be switched for only a predetermined time (for example, 2 seconds).

As shown in FIG. 2, the digital broadcast reception device first receives a broadcast signal of a specific broadcast channel according to a user's broadcast viewing request input in operation S201. In addition, the digital broadcast reception device receives and stores the electronic program guide through the specific broadcast channel or a channel separate from the corresponding broadcast channel (S203).

The digital broadcast reception device demodulates and decodes the received broadcast signal and displays the received broadcast signal on the display unit (S205). While displaying the broadcast signal, the digital broadcast reception device receives a broadcast channel switching input from the user (S207). In this case, the digital broadcast reception device may display a list of broadcast channels that the user can watch on the screen and receive a channel change input to any one of them, or switch the channel from the currently displayed broadcast channel to the next broadcast channel. You can also receive input.

Upon receiving the broadcast channel switch input, the digital broadcast receiver checks the duration of the broadcast channel switch input (S209). Subsequently, the digital broadcast receiver determines whether the duration of the broadcast channel switching input is less than a threshold time (S211).

If the duration of the broadcast channel switching input is less than the threshold time, the digital broadcast reception device extracts broadcast program information of a broadcast channel to be switched from the received electronic program guide (S213), and extracts the extracted broadcast program information for a predetermined time. Displayed on the screen (S215).

After displaying the program information on the screen for a predetermined time, the digital broadcast receiving apparatus displays the broadcast screen of the switched broadcast channel on the screen (S217).

On the other hand, if the duration of the broadcast channel switching input checked in step S209 is greater than or equal to the threshold time, the digital broadcast receiving apparatus does not extract the information of the broadcast program of the broadcast channel to be switched from the electronic program guide, but instead of the broadcast channel to be switched immediately. The demodulation and decoding of the broadcast signal is immediately displayed on the screen (S217).

As described above, according to the method for changing a broadcast channel according to the present embodiment, a user may check program information of a broadcast channel to be switched according to a user's selection when a channel moves. That is, the user may shortly press a broadcast channel switching input (by pressing and holding the direction key on the keypad or shortly pressing the OK button on the touch pad) to change the broadcast program information of the moved channel in the process of moving to another broadcast channel. If it is not the program you want to check, you can change to another broadcast channel immediately. On the other hand, if the program information of the next broadcast channel is known in advance, the user can watch the broadcast of the next broadcast channel without previewing the broadcast program information by long pressing the broadcast channel switch input. Therefore, the time for displaying broadcast program information on the screen can be reduced.

The digital broadcast reception device demodulates and decodes the received broadcast signal and displays the received broadcast signal on the display unit (S305). While displaying the broadcast signal, the digital broadcast reception device receives a broadcast channel list display input from the user (S307), and displays a broadcast channel list that the user can watch on the screen (S309).

In the state where the broadcast channel list is displayed on the screen, the digital broadcast reception device receives a selection input of one broadcast channel from the user (S311).

Upon receiving the selection input of the broadcast channel, the digital broadcast reception device checks whether the broadcast channel selection input is double click (S313). When the broadcast channel selection input is a double click, the digital broadcast reception device extracts the broadcast program information of the broadcast channel selected by the user from the received electronic program guide (S315), and displays the extracted broadcast program information on the screen for a predetermined time. It is displayed (S317). After displaying the broadcast program information on the screen for a predetermined time, the digital broadcast receiving device displays the broadcast program of the switched broadcast channel on the screen (S319).

On the other hand, when the broadcast channel selection input is one-click in step S313, the digital broadcast reception device demodulates and decodes the broadcast signal of the switched broadcast channel without extracting the information of the broadcast program of the next broadcast channel from the electronic program guide. Immediately display on the screen (S319).

As described above, according to the method for changing a broadcast channel according to the present embodiment, a user may check program information of a broadcast channel to be switched according to a user's selection when a channel moves. That is, in a terminal supporting a touch pad, a user double-clicks a broadcast channel in a process of selecting a broadcast channel to check broadcast program information of the selected broadcast channel and immediately changes to another broadcast channel if it is not a desired program. can do. On the contrary, if the program information of the selected broadcast channel is known in advance, the user can directly view the program of the broadcast channel without previewing the broadcast program information by one-clicking on the corresponding broadcast channel. Therefore, the time for displaying broadcast program information on the screen can be reduced.

Unlike this embodiment with reference to FIG. 3, a user presses a specific key (for example, a shift key, a predetermined direction key, or a special key) in any broadcast channel list of the broadcast channel list to broadcast programs of the corresponding broadcast channel. Embodiments in which information is displayed are also possible. When a confirmation click or a confirmation button is input instead of a specific key, the broadcast program is displayed immediately without displaying the broadcast program information.
