The present invention relates to a method of acquiring and modifying channel information through a channel map, and more particularly, to display channel map information on a screen in a channel list format and to provide channel preference information according to the day and time in the channel list. Channel sorting, channel deletion, and channel addition in a map can be adjusted simultaneously for multiple channels, and it relates to a method of acquiring and modifying channel information through a channel map that provides convenience to consumers.

In general, digital broadcasting is a broadcasting technology because it provides a clear image quality and sound quality comparable to a compact disk (CD), and provides a plurality of channels to provide a high quality service that is different from existing analog broadcasting.

These digital broadcasts use a wide bandwidth to significantly increase the number of channels that viewers can watch, so that unlike analog broadcasts, a single physical channel does not contain only one broadcast, but multiple programs can be transmitted simultaneously. do.

Accordingly, digital broadcasting enables each broadcasting station to configure a number of channels larger than existing analog broadcasting, thereby allowing a user to experience many channels.

In addition, since the program configuration may change from time to time, the Electronic Program Guide (EPG) function, which can show viewers a broadcast program guide in the future, is essential for digital broadcasting, and is emerging as the most distinguishing factor.

In addition, the 16: 9 aspect ratio is similar to the movie screen, so users can see the realistic screen.

On the other hand, in digital broadcasting, video and audio streams are compressed and broadcast as digital information, and system information and program information are compressed and broadcast in accordance with the Program and System Information Protocol (PSIP) standard.

This PSIP is a protocol that transmits additional information containing information necessary for viewing DTV established by the US Advanced Television Systems Committee (ATSC). PSIP is designated as ATSC document number A / 65 and DTV (Digital Television) It contains program programming information as well as audio / video location for viewing the screen.

However, after analyzing the data of the PSIP, finding the location of the audio / video signal has a problem that the user is several times later than the analog broadcast when channel tuning. Therefore, users have a problem in that despite the many advantages of DTV, it takes a lot of time to change the channel, which is the most basic operation, so that it is inconvenient.

The present invention has been made to solve the above problems of the prior art, and displays channel map information on the screen in the form of a channel list, provides channel preference information according to the day and time in the channel list, and provides a channel in the channel map. The purpose of the present invention is to provide a method of acquiring and modifying channel information through a channel map that provides convenience to consumers by enabling sorting, channel deletion, and channel addition to multiple channels at the same time.

According to the present invention for achieving the above object, in the channel map modification method of the television system, when the channel map key is selected from the remote control or the local key of the television, the channel map information is displayed on the screen in the form of a channel list, In the displayed channel list, the user can simultaneously perform channel movement, channel sorting, channel deletion, and channel addition.

In the present invention, the channel list displays the channel name and the channel number, and simultaneously displays channel preference information according to the date, day, and time of each channel.

In the present invention, channel sorting, channel deletion, and channel addition in the channel list are performed by placing a separate menu for sorting, deleting, and adding the channel along with the channel list, and channel movement moves the cursor to a desired channel. Press the enter key to move directly to the channel or directly enter the number to select a channel.

As described above, the present invention displays channel map information on a screen in the form of a channel list, provides channel preference information according to the day and time in the channel list, and performs channel sorting, channel deletion, and channel addition in the channel map for various channels. It can be adjusted at the same time to provide convenience to the consumer.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 is a flowchart illustrating a method of acquiring and modifying channel information through a channel map according to the present invention, and FIGS. 2 and 3 are views for explaining the configuration and operation of a channel map according to an embodiment of the present invention.

As shown in Figs. 1 to 3, in the channel map modification method of the television system, when the channel map key is selected from the remote control or the local key of the television (S10), the channel map information is converted into a channel list format. Display on the screen (S20).

Of course, the channel map is displayed on the television screen in the OSD.

In addition, the user simultaneously performs channel movement, channel sorting, channel deletion, and channel addition in the displayed channel list (S30).

Here, the channel list displays the channel name and the channel number, and simultaneously displays channel preference information according to the date, day, and time of each channel.

In addition, channel sorting, channel deletion, and channel addition in the channel list are performed with a separate menu for sorting, deleting, and adding the channel together with the channel list, and the channel movement is performed by moving a cursor to a desired channel. Press the Enter key to go directly to that channel or enter a number directly to select a channel.

Subsequently, when the channel map key is turned off, the channel map displayed on the screen ends (S40).

That is, according to the present invention, in order to reduce the switching time by shifting the channels stored one by one through the auto tuning process, the channel map information is output in the channel list format when a specific key is pressed and the cursor is moved on the channel list. Move and press Enter to go directly to that channel.

In addition, the channel list existing in the channel map is provided with channel list information for channels with a high frequency of channel selection according to the date, day of the week, and time.

As described above, the present invention can identify several channels at a glance, and when the channel sequence is moved, the channel map OSD remains as it is, but the channel map sequence moves directly to the channels in the channel map sequence, thereby reducing the channel selection time.

In addition, the present invention can be easily modified, such as deletion and addition to the channel information, and the preferred channel information according to the date is provided so that the priority can be selectively arranged according to the preference when sorting the channel.

As described above, the present invention displays channel map information on a screen in the form of a channel list, provides channel preference information according to the day and time in the channel list, and performs channel sorting, channel deletion, and channel addition in the channel map. There is an advantage in providing convenience to the consumer by allowing simultaneous adjustments to the channel.
