Since the electronic program guide screen 100 displays program information of a plurality of broadcast types (terrestrial wave, BS), when viewing the terrestrial wave, it cannot be viewed unless the broadcast is switched. BS program information can be easily viewed simply by operating the cursor button.

  For example, it is assumed that an electronic program guide is displayed by operating a remote controller while a viewer is watching terrestrial waves. In this case, as shown in FIG. 3, an electronic program guide screen 100 giving priority to the channel of the terrestrial wave (“terrestrial D”) is displayed. Next to the terrestrial channel (below), the BS channel is displayed. If there are channels that cannot be displayed on one screen, they can be displayed by a scroll operation or page switching operation by the user.

  In the embodiment according to the present invention, in the electronic program guide in which a plurality of broadcast types are combined into one, direct key display is performed in association with any one broadcast type channel so that direct key display does not overlap. That is, on the electronic program guide screen 100 displayed on the display unit, when a plurality of broadcast type channels to which the same direct key is assigned according to predetermined assignment data are displayed at the same time, any one channel is displayed.

  Here, it is assumed that the digital broadcast receiving apparatus holds channel number assignment data for direct keys as shown in FIG. This assignment data is data that is assigned and stored with a specific direct key for each channel of a plurality of broadcast types. In the digital broadcast receiving apparatus, using this allocation data, a direct key for selecting a channel is set for any one of a plurality of broadcast type channels. The setting of a direct key for a channel refers to a process of setting a direct key for selecting a channel for a specific broadcast type channel within the apparatus. The direct key to be set is selected from the direct keys assigned to each broadcast type channel by assignment data as shown in FIG.

  In this case, in this embodiment, priority is given to the broadcast type currently being viewed, that is, the broadcast type displayed on the display unit when the operation for displaying the electronic program guide is performed, and the channel of the priority broadcast type is set. Set the direct key for it.

  In the example of FIG. 3, terrestrial waves are prioritized and direct keys are set for terrestrial channels. The direct key number display section 103 of the electronic program guide screen 100 displays the direct key number for the channel for which the direct key is set. When the BS channel to which the direct key set for the terrestrial channel is assigned is displayed, the direct key is not set and displayed for the BS channel on the electronic program guide screen 100.

  In this example, in the assignment data of FIG. 22, the direct key “1” is assigned to the terrestrial (“terrestrial D”) channel “011” and the BS channel “101”. On the electronic program guide screen 100 shown in FIG. 2, the terrestrial channel “001” and the BS channel “101” are displayed at the same time. Accordingly, the terrestrial wave currently being watched is prioritized, and the direct key “1” is set for the terrestrial channel “011”. ”Is displayed. The direct key is not displayed on the channel “101” of the BS on the electronic program guide screen 100.

  FIG. 4 is a view showing another example of the display screen of the electronic program guide displayed by the digital broadcast receiving apparatus according to the present invention. The priority of the broadcast type for setting the direct key may be determined in advance as appropriate as well as the broadcast type currently being viewed as described above. The priority order of broadcast types can be stored in advance in the memory unit of the broadcast receiving apparatus.

  In this state, on the electronic program guide screen 100, the terrestrial channel “011” disappears by scrolling. Accordingly, the setting of the direct key “1” for the terrestrial channel “011” is canceled, and the setting of the direct key “1” for the channel “101” of the BS is changed. Then, on the electronic program guide screen 100, the direct key “1” is displayed on the direct key number display section 103 corresponding to the BS channel “101”. The channel “101” of the BS is another channel to which the direct key “1” is assigned according to the data of FIG.

  FIG. 6 is a diagram illustrating an example of a display screen when the electronic program guide display screen is further scrolled. When the electronic program guide screen 100 in the state shown in FIG. 5 is further scrolled downward, the terrestrial channel is displayed again after the BS channel. At this time, while the BS channel “101” for which the direct key “1” is set in FIG. 5 is displayed on the electronic program guide screen 100, the terrestrial channel “011” having a higher priority is displayed at the same time. Even if the direct key "1" is set, the display is not changed.

  As shown in FIG. 6, when the BS channel “101” disappears from the electronic program guide screen 100 due to the scrolling of the electronic program guide, the setting of the direct key “1” is changed for the terrestrial channel “011”. Then, the direct key “1” is displayed on the terrestrial channel “011” of the electronic program guide screen 100.

When one direct key is assigned to a plurality of channels displayed on the display screen of the electronic program guide screen 100 as described above, one broadcast type channel is assigned in accordance with a predetermined broadcast type priority. In the electronic program guide screen 100, information on the set direct key is displayed in association with the channel.
Then, the display state of the electronic program guide is changed by scrolling or changing the page of the electronic program guide screen 100, the channel for which the direct key has been set is not displayed, and the same direct key as the channel that is not displayed is assigned. If a channel of another broadcast type that is assigned is displayed, the setting of the direct key assigned to the channel that is no longer displayed is changed to a channel of another broadcast type to which the direct key is assigned. The direct key display on the electronic program guide screen is also changed to the newly set channel.

  As a result, when displaying an electronic program guide in which channels of a plurality of broadcast types are displayed, the channel actually set in the direct key and the channel on which the direct key is displayed on the electronic program guide screen 100 are matched. Thus, the user can surely and easily recognize to which channel of which broadcast type the direct key is currently set.

In the present embodiment, the same direct key is displayed on the electronic program guide screen 100. When channels of a plurality of assigned broadcast types are displayed at the same time, a direct key is set with priority given to a channel corresponding to a program frame (program information display frame) where the cursor 105 is located, and the electronic program guide screen 100 is displayed. Process to be displayed on.

  For example, in the electronic program guide screen 100 of FIG. 7, the cursor 105 is positioned in the program frame of the terrestrial channel “011”. In this case, the terrestrial channel “011” corresponding to the cursor 105 is given priority, and the direct key “1” assigned to the terrestrial channel “011” is set according to the assignment data of FIG. The direct key “1” is displayed on the terrestrial channel “011” of the electronic program guide screen 100.

FIG. 8 is a diagram showing an example of a display when the cursor is moved on the electronic table program screen of FIG. For example, in the electronic program guide screen 100 in the state shown in FIG. 7, it is assumed that the user operates the cursor button to move the cursor 105, resulting in the state shown in FIG.
In this case, the BS channel “101” corresponding to the program frame where the cursor 105 is currently located is prioritized, the setting is changed to the direct key “1” assigned to the channel “101”, and the electronic program guide is changed. The display of the direct key “1” is changed to the BS channel “101” on the screen 100.

FIG. 9 is a diagram showing an example of a display when the cursor is further moved on the electronic program guide screen of FIG. When the cursor 105 is moved on the electronic program guide screen 100 in the state shown in FIG. 8, the setting and display of the direct key “1” for the channel “101” of the BS is different from that to which the direct key “1” is assigned. As long as the cursor does not move to the position corresponding to the broadcast type channel, it is maintained as it is.
In FIG. 9, only the cursor 105 has moved in the display state of FIG. 8, and has moved to the program frame of the terrestrial channel “051”. In this state, the setting and display of the direct key “1” for the channel “101” of the BS is maintained without being changed. Thereafter, when the cursor 105 further moves and the cursor 105 is positioned in the program frame of the terrestrial channel “011”, the direct key “1” set in the BS channel “101” is set. The direct key “1” is set to the terrestrial channel “011” again. Further, the direct key display of BS channel “101” on the electronic program guide screen 100 is cleared, and the direct key “1” is displayed on the terrestrial channel “011”.

  Thus, in the present embodiment, the direct key is set with priority given to the channel corresponding to the program frame where the cursor is located on the electronic program guide screen, and the direct key number is assigned to the channel corresponding to the program frame where the cursor is located. To be displayed.

FIG. 11 is an example of the display screen when the cursor is moved on the display screen of FIG. FIG. 12 is a diagram showing a display screen example when the cursor is further moved on the display screen of FIG.
In this example, as in the above examples of FIGS. 7 to 9, on the electronic program guide screen 100, the direct key is set with priority given to the channel of the program frame where the cursor 105 is located, and is displayed on the electronic program guide screen 100. When the cursor 105 is positioned in the program frame of the currently broadcast program (program information display frame) at this time, direct keys are set and displayed for the channel, and the current broadcast is performed. When it is located in a program frame of a program that has not been set, the direct key is not set and displayed for that channel.

  For example, in the electronic program guide screen 100 of FIG. 10, the cursor 105 is positioned in one of the program frames of the terrestrial channel “011”. In this case, the terrestrial channel “011” corresponding to the cursor 105 is given priority, and the direct key “1” assigned to the terrestrial channel “011” is set according to the assignment data of FIG. The direct key “1” is displayed on the terrestrial channel “011” of the electronic program guide screen 100.

Next, on the electronic program guide screen 100 in the state shown in FIG. 10, it is assumed that the user operates the cursor button to move the cursor 105, resulting in the state shown in FIG.

In the example of FIG. 9, the starting point in the time axis direction of the program frame display unit 104 is at the left end of the program frame display unit 104. In the case of FIG. 11, the program in the program frame where the cursor 105 is currently located is a program that is broadcast when the scheduled broadcast time is reached, and is not currently broadcast.

  Referring to the assignment data in FIG. 22, the direct key “1” is assigned to the channel “101” of the BS, but in the case of FIG. 11, the cursor 105 is positioned in the program frame of the program that is not currently broadcast. Therefore, it maintains without changing the direct key setting and display.

  Further, it is assumed that the cursor 105 is further moved to a state as shown in FIG. In the electronic program guide screen 100 of FIG. 12, since the cursor 105 is positioned in the program frame of the currently broadcast program, the BS channel “101” is preferentially assigned to the channel “101”. The setting is changed to the direct key “1”, and the display of the direct key “1” is changed to the BS channel “101” of the electronic program guide screen 100.

  Thus, in the present embodiment, when the cursor is positioned on the program frame of the program currently being broadcast on the electronic program guide screen, the direct key is given priority over the channel corresponding to the program frame where the cursor is positioned. Set and display the direct key on the channel corresponding to the cursor position. When the cursor is positioned on the program frame of a program that is not currently being broadcast in the electronic program guide, the direct key setting and display change are not performed.
