Description

  The present invention relates to a disc device capable of receiving a digital broadcast capable of broadcasting a program of a plurality of subchannels on one physical channel, wherein the control unit of the disc device and the control unit of the television receiving device are connected by bus communication. The present invention relates to a built-in television receiver.

  In digital broadcasting, a virtual channel is assigned to a physical channel indicating a frequency band. The virtual channel is used for allowing the user to recognize the relevance of these physical channels when the same broadcasting station or affiliated broadcasting station broadcasts a program using a plurality of physical channels. For example, by assigning the same virtual channel number to a plurality of physical channels used by the same broadcast station or affiliated broadcast station, the user is made aware of the relationship between these physical channels.

  In digital broadcasting, since a plurality of programs are broadcast simultaneously on one physical channel, subchannels are provided. The program is broadcast in subchannel units.

  Therefore, when a user selects a program to be watched, a complicated operation such as selecting a physical channel first and then selecting a subchannel in the physical channel is required. Has been conventionally proposed (see, for example, Patent Document 1).

   In the technique described in Patent Document 1, the left and right keys of the keys of the remote control transmitter are assigned for cursor movement for switching physical channels, and the up and down keys are used for cursor movement for switching subchannels in one main channel. Assigned to. Specifically, a channel information table (channel map) displaying a list of all combinations of a physical channel and all subchannels included in the physical channel is displayed as an EPG (Electric Program Guide) on the display device, and this channel is displayed. By moving the cursor displayed at an arbitrary position on the map using the up / down key or the left / right key, a desired subchannel in the desired physical channel is selected from the displayed channel map. .

Here, the channel information table has a configuration in which physical channels are arranged in the horizontal direction and sub-channels are arranged in the vertical direction, and the physical channels arranged in the horizontal direction are selected by moving the cursor left and right with the left and right keys. By moving the cursor up and down with the up and down keys, the subchannels arranged in the vertical direction are selected.
JP 2002-223396 A

  As described above, in Patent Document 1, a physical channel is selected with the left and right keys, and a subchannel is selected with the up and down keys. However, this operation is realized on the assumption that the display screen of the channel information table OSD displayed on the display device has a grid structure in which physical channels are arranged in the horizontal direction and subchannels are arranged in the vertical direction. It is an operation. In other words, the up and down keys only move the cursor on the screen up and down, the left and right keys only move the cursor on the screen to the left and right, and only the physical channel is switched directly with the left and right keys, and the up and down keys are used. Not only the subchannel is switched directly. That is, the cursor is simply moved to a desired position on the channel information table by the left / right key or the up / down key. Such an operation is exactly the same as the operation of the up / down key and the left / right key when the menu screen is displayed on the display device by OSD display and a predetermined item on the menu screen is selected. Is not different from the conventional up / down / left / right key operation function.

  In the case of a television receiver with a built-in disk device, in fast-forward playback and rewind playback on the disk device, a horizontal bar indicating the playback position is displayed on the screen by the OSD display, and the cursor is positioned at the playback position on the bar.

In accordance with this, the cursor K also moves to the left on the channel bar B. However, as for the physical channel, it is assumed that 10 adjacent channels are 35 channels.

  In this case, in the present embodiment, the subchannel S is automatically switched to “0”. However, in this case, the subchannel S may be “2” and not switched.

  Next, when the user presses the rewind (REW) key 41hR of the remote control transmitter 41 once from the channel selection screen shown in FIG. 3A (No in step S1, Yes in step S5, Yes in step S6). In the channel selection screen, as shown in FIG. 3D, the channel number M of the physical channel remains as it is (that is, remains “10”), and the channel number S of the subchannel starts from “2”. It switches to “1” (step S7).

  On the other hand, when the fast forward (FF) key 41hF is pressed once (No in step S1, Yes in step S5, No in step S6), the channel selection screen is displayed as shown in FIG. The channel number M of the channel remains unchanged (that is, remains “10”), and the channel number S of the subchannel is switched from “2” to “3” (step S8).

  In this case, if the channel number “10” of the physical channel includes only the channel number S of the subchannel up to “2”, the TV-side microcomputer 21 switches to the physical channel one level higher. . That is, the channel selection screen shown in FIG. 3C is displayed. However, when the fast forward (FF) key 41hF is pressed once and there is no corresponding subchannel, it may be configured to return to the subchannel number “0” in the same physical channel again.

  Further, when the rewind (REW) key 41hR is pressed once when the subchannel number is “0”, it may be configured to switch to the next lower physical channel. Alternatively, it may be configured to return to the subchannel number “2” in the same physical channel again.

  Thus, in the present invention, the physical channel is directly switched by the skip up / down key 41i, and the subchannel is directly switched by the fast forward / rewind key 41h.

  In order to view the channel selected in this way, the determination key 41k of the remote control transmitter 41 may be pressed in the state of the channel selection screen.
