Description

Method for setting channel property of video signal receiving device {Method for setting an channel attribution of television receiver}

The present invention relates to a channel-specific property setting method of an image signal receiving apparatus, and more particularly, to a channel-specific property setting method that can set a video mode, an audio mode, a screen size, and the like by channel and group.

In a conventional television receiver, an attribute such as a screen mode, a voice mode, a screen size, or the like is set in accordance with the characteristics of a program to be viewed using an environment setting menu or a dedicated setting key. However, since the attribute setting value is not to set the attribute for the channel, when watching a program of another channel, there is a problem that the user needs to set an attribute appropriate for the characteristics of the corresponding program.

On the other hand, as digital broadcasting starts, the number of broadcasting channels is dramatically increased compared to analog broadcasting, and technologies for simplifying channel selection have been developed. For example, there are techniques that reduce the time of channel search and selection by allowing a user to register and select channels or genres according to genres.

The channels preferred by the user are registered by manual registration by the user or by automatically registering channels frequently selected by analyzing the user's usage history.

Genre channels are registered by a method of automatically classifying and registering by genre based on program guide information transmitted by being included in a program.

However, since there is no method for setting the proper properties for each preferred channel or genre even in the preferred channel or genre-specific channel, there is a problem in that the user must reconfigure the attribute every time he / she watches the corresponding preferred channel or genre.

The present invention has been devised to solve the above problems, and an object thereof is to provide a method for registering an attribute for each channel / group in an image signal receiving apparatus.

1 is a flowchart showing a preferred embodiment of the method for setting channel properties according to the present invention.

2 illustrates an example of a screen for setting channel attributes in the method illustrated in FIG. 1.

Channel property setting method according to the present invention for achieving the above object

Receiving a channel for setting a property of a screen, a voice, etc .;

Allowing assigning an attribute to a selected channel; And

And storing the selected channel and the attributes assigned thereto.

Here, it is preferable to give the same property to all the channels of the group to which the channel to which the property is assigned.

In addition, it is preferable to further include a process of allowing setting of a group for the selected channel.

Hereinafter, the detailed configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart showing a preferred embodiment of the method for setting channel properties according to the present invention.

First, it is determined whether the channel property setting mode (s102). The channel property setting mode may be activated using a menu or a dedicated setting key.

In the channel attribute setting mode, the channel attribute is set in response to the user's selection, and the channel attribute mode is terminated (s104). The channel-specific attribute is stored in the memory for later reference.

The channel selection information is input (s108).

It is determined whether an attribute is set in the selected channel (S110). That is, it is determined whether the attribute is set for the selected channel with reference to the memory.

If a property is set in the selected channel, video and audio signals are output using the set property (s112), otherwise, the property set as a default is used (s114).

2 illustrates an example of a screen for setting channel attributes in the method illustrated in FIG. 1.

In FIG. 2, the first column is icons for menu selection, the second column is channel numbers, the third column is channel names, the fourth column is channel frequencies, the fifth column is group numbers, and the sixth column is Screen attributes are the seventh column, acoustic attributes, and column eight are the screen size attributes.

Referring to the first row of FIG. 2, channel 1 (channel name MBC, frequency 40MHz) belongs to group 1, the screen property is' standard ', the voice property is' custom', and the screen size is' 4: It has 3 "attributes.

In Fig. 2, the cursor movement between the menu items 202 is made by the channel up / down keys, and the selection of the menu items is performed by the enter key.

When a menu item labeled 'CH' is selected on the menu screen, a screen as shown in FIG. 2 is displayed on the screen, and a channel-specific attribute setting mode is activated. 2 is only an example of a screen for setting a property for each channel, and other screen configurations are also possible. In addition, since a method of outputting corresponding information on the screen in response to the user's selection is well known to those skilled in the art, a detailed description thereof will be omitted.

In the screen shown in FIG. 2, cursor movement between columns is performed by volume up / down keys, and cursor movement between rows is performed by channel up / down keys.

Through the screen shown in FIG. 2, a user can designate a group number, screen property, voice property, and screen size property for a channel.

If you press the Enter key while the cursor is located at the position to designate group property, screen property, voice property, and screen size property, you can enter each property, and in this state, use the numeric keys, channel up / down keys, etc. To navigate to the desired property.

The group number may be designated as a number, but may also be inputted using a method using letters on the telephone button. On the other hand, the group attribute may be set automatically. For example, when a method of setting preference channels according to a user's viewing history is applied, the group number may have a preset preference group, and when a method of classifying and registering channels by genre by analyzing program guide information is applied. Channels may have a preset genre.

The screen properties are standard, movie, custom, dynamic, and so on. They change in response to channel up / down keys.

Voice attributes include standard, music, speech, custom, and stereo, mono, turbo, etc., which are changed in response to channel up / down keys and voice up / down keys.

The screen size properties include auto wide, wide, panorama, zoom1, zoom2, stretch, 14: 9, normal standad, full, normal (PC or DVI mode), and are sequentially changed in response to the channel up / down keys.

Press the Enter key while the desired property is displayed to set the selected property.

On the other hand, if the same group attribute is defined for a plurality of channels, if the attribute is set for a channel belonging to the same group, the attribute of all channels belonging to the group is set to the same value. For example, in FIG. 2, although not explicitly shown, the attributes "standard, custom, and 4: 3 'set to the channel 1 for channels 1 to 3 in which the group 1 property is set are the same. do.

Attributes set for each channel / group are stored in the memory and referenced later for channel selection.
