BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast receiver such as a television receiver, a satellite broadcast decoder, and a terrestrial digital broadcast decoder. And a broadcast receiving device having a function of decoding.

[0002]

2. Description of the Related Art In a conventional broadcast receiving apparatus, in order to easily select a target channel from a large number of receivable channels, some frequently viewed channels are registered and transmitted by remote control. Channel selection means for sequentially selecting registered channels by operating a channel up / down key of a device are often used. However, with the rapid spread of digital broadcasting, the number of channels of broadcasting has been increasing, and the number of channels that users frequently watch has been diversified, and the number of channels has been increasing.

[0003]

In conventional program registration, simply increasing the number of channels that can be registered increases the number of items in a channel list, so that it takes a long time to select an original channel. Relax,
There was a disadvantage that not all channel lists could be displayed on the screen. The present invention has been made in order to solve the above-mentioned problem, and allows a user to configure a channel list of an arbitrary number of levels most suitable for the user with a simple operation, and use the list to select a channel in a multi-channel broadcast. An object of the present invention is to provide a broadcast receiving apparatus that can be easily performed.

[0004]

In order to achieve the above object, a channel list storage memory for storing a plurality of channel lists created by a user, and channel registration means for registering a new channel in the channel list. A channel deleting unit for deleting a specific channel from the channel list; an inter-list moving unit for registering and moving a specific channel among the plurality of channel lists; and calling one of the plurality of channel lists and displaying a display signal. Channel list display means for outputting as a display, an OSD display control means for generating an on-screen display signal of a display signal from the channel list display means and displaying the signal on a screen, and displaying on the screen by the OSD display control means A specific channel in the channel list Selection, a channel selection means, and a broadcast receiving apparatus having a control means for controlling the operation of each means, wherein the plurality of channel list is divided into levels in the order of higher viewing frequency of the user A broadcast receiving apparatus characterized by being a registered channel list is provided.

FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, a remote control code acquisition unit 1 receives and acquires a code corresponding to a button of a remote control transmitter pressed by a user, and supplies the code to a control unit 2. The control means 2 controls the channel registration means 3, the inter-list movement means 4, the channel deletion means 5, the channel list display means 6, and the channel selection means 7 according to the remote control code acquired by the remote control code acquisition means 1. I have. As a result, with respect to the channel list in the channel list storage memory 8, operations such as registering a new channel, moving between the lists, and deleting the registered channel are controlled. Display on the screen or select a channel selected by the user.

The channel list display means 6 calls up a channel list of one level from the memory 8 for storing the channel list, and displays the OSD display control means 9 as a display signal.
To supply. The OSD display control means 9 generates an OSD (on-screen display) signal relating to the registered channel list and supplies the signal to the adder 11. The tuning means 7 selects a channel selected by the user by operating a channel up / down key, and supplies data of the channel to the video decoding means 10. The video decoding unit 10 decodes the data of the selected channel, converts the data into a video signal, and supplies the video signal to the adder 11. The adder 11 mixes the video signal and the OSD signal, and mixes the video signal and the OSD signal on the video of the selected channel.
The video whose OSD overlaps is supplied to the display device 12 and displayed.

The channel registration means 3 adds and registers the currently viewed channel to the channel list of the channel list storage memory 8. FIG. 2 is a diagram illustrating an example of a channel list according to the present invention. As shown in the figure, the information of each channel registered in the list includes a total of 4 bytes of channel number data (2 bytes) and level number data (2 bytes) of the list indicating which level of the list is registered. Store as data. For example, assuming that the number of lists (the number of levels) is 3, (Level 1) a list of channels that are viewed most frequently, (Level 2) a list of channels that are frequently viewed, (Level 3) a list of channels that are sometimes viewed,
The list is used in descending order of the frequency of viewing. In Figure 2, the level 1 channel list contains 1, 3,
Channels 4, 7, and 8 have 10, 1 in the level 2 list
In this example, channels 2, 16, 17, and 20 are registered in the level 3 list with channels 25, 36, 38, and 42.

Hereinafter, an actual channel registration operation using the remote control transmitter will be described. FIG. 6 is a diagram showing an example of a button arrangement of the remote control transmitter according to the present invention. The remote control transmitter includes [Registration / deletion], [Cursor up], [Cursor down], [Cursor right], [Cursor left],
There are [Level +] and [Level-] buttons. In the case of channel registration, when the [register / delete] button of the remote control transmitter is pressed while the channel list is not displayed, the channel being viewed at that time can be registered in the list.

The inter-list moving means 4 operates to move one channel in a list of a certain level to another level. FIG. 3 is a diagram showing an example of movement between lists according to the present invention. In the movement between lists, the level number of the channel to be moved may be changed to the level number (list number) of the movement destination. In the example shown in FIG. 3, channel 12 is moved from level 2 to level 1, and channel 38 is moved from level 3 to level 4. Hereinafter, the actual operation of moving between lists using the remote control transmitter will be described. With the channel list displayed, pressing the [Level-] button moves the currently selected channel down one level, and pressing the [Level +] button changes the currently selected channel. Move up one level.

As described above, when the channel is moved between the lists, the number of channels is reduced by one from a certain list, and the list may become empty when the channel is moved many times. In this case, this list (level) automatically disappears. For example, if there are three levels (levels 1, 2, and 3), level 2
Disappears, level 3 is promoted to level 2 and the gap is shortened. If the level is lowered when no lower level exists, the lower level is automatically created.
For example, lowering level 3 will create level 4. Similarly, when a level is raised when a higher level does not exist, an upper level is created.

The channel deleting means 5 is a means for deleting a channel registered in the channel list. FIG. 4 is a diagram showing an example of channel deletion in the present invention. To indicate that the channel has been deleted, for example, the level number of the deleted channel may be set to 0. Hereinafter, the actual channel deletion operation using the remote control transmitter will be described. When the [Register / Delete] button is pressed while the channel list is displayed, the currently selected channel is deleted from the list.
At this time, the channel disappears from the list, and the next lower or upper channel is automatically selected. If the list is emptied by deletion, the list will automatically disappear.

FIG. 5 is a diagram showing an example of a channel list screen display according to the present invention, in which the level 1 list of the channel list data shown in FIG. 2 is displayed on the screen. In this example, a list of only the channel numbers is displayed, but it is more convenient to display the description of the channel such as the broadcast station name at the same time as the channel number. In this case, the description may be simultaneously stored in the channel list data in the channel list storage memory 8. The user selects a channel by operating a channel up / down key of the remote control transmitter while watching the channel display. In the channel selection means 7,
The actual channel selection operation using the remote control transmitter will be described below. If the [Cursor Down] button is pressed while the channel list is not displayed, the level 1 channel list is displayed on the screen. At this time, the top channel of the list is selected.

[0013] With the channel list displayed,
Press the [Cursor Up] button to select the next higher channel in the list. Press the [Cursor Down] button to select the next lower channel in the list. The display in the list also shows that channel. The display changes to the selected display. If you press the [Cursor Up] button while the top channel in the list is selected, the bottom channel in the list will be selected and the bottom channel in the list will be selected. When the [cursor down] button is pressed, the top channel in the list is selected. or,
While the channel list is displayed, [Cursor right]
When the button is pressed, the display switches to the level list one level lower than the currently displayed channel list,
When the [Cursor left] button is pressed, the display switches to the next higher level list. If the lower or upper list does not exist, it does not switch.

As described above, in the present invention, a plurality of channel lists are provided, and the number of channels registered in each list and the number of lists can be freely set by the user. (A certain limit may be given.) In addition, it is possible to easily move between registered channel lists (levels). When the user wants to select a channel, pressing a specific button on the remote control transmitter first displays a level 1 list. Only when a different list is to be displayed, a specific key may be pressed to switch the list to be displayed.
Therefore, for example, assuming that the number of lists (the number of levels) is 3, (Level 1) a list of the most frequently viewed channels, (Level 2)
The most frequently used channel list can be selected by using the most frequently viewed list, such as the list of frequently-viewed channels and the (level 3) list of channels that are viewed occasionally, and constructing the most appropriate channel list for each user Becomes

[0015]

According to the broadcast receiving apparatus of the present invention, a user can construct a channel list of an arbitrary number of levels most suitable for the user by a simple operation, and can easily select a channel in a multi-channel broadcast using the list. There is an extremely excellent effect that it can be performed.
