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. The present invention relates to a method of acquiring and modifying channel information through a channel map that provides convenience to consumers by allowing channel sorting, channel deletion, and channel addition operations in a map.

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 was devised to solve the above-mentioned problems of the prior art, and 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 provides a channel on 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 allowing sorting, channel deletion, and channel addition to be adjusted.

According to the present invention for achieving the above object, in the method of obtaining and modifying channel information through a channel map, when a channel map key is selected from a remote controller or a local key, the channel map information is displayed on a screen in a channel list format. In the displayed channel list, the user can perform 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, the channel sorting and the channel deletion and the channel addition in the channel list are performed with a separate menu for sorting, deleting or adding the channel together with the channel list to perform a function of the corresponding menu when selecting a menu. .

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 adjusts channel sorting, channel deletion, and channel addition in the channel map. To give convenience.

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.

1 to 3, when the channel map key is selected from the remote control or the local key of the television (S10), the channel map information is displayed on the screen in a channel list format (S20).

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

In addition, the user selectively performs channel sorting, channel deletion, and channel addition in the displayed channel list (S30). Here, the channel list indicates channel names and channel numbers, and displays channel preference information according to date, day, and time for each channel, and performs channel sorting, channel deletion, and channel addition together with the channel list. Each menu for sorting, deleting, and adding channels is placed so that the function of the menu is executed when the menu is selected.

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

Meanwhile, in the present invention, in order to reduce the channel switching time during which the channel information is stored by switching channels one by one through auto tuning, channel map information is output in a channel list format when a specific key of the remote controller is pressed and the cursor is moved over the channel list. By pressing the Enter key, you can move directly to the channel.

In addition, the channel list existing in the channel map provides channel preference information to channels having 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 if the channel sequence is moved, the channel map OSD remains as it is and the channel map sequence can be directly moved to reduce 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 can display the channel map information on the screen in the form of a channel list, provide channel preference information according to the day and time in the channel list, and adjust channel sorting, channel deletion, and channel addition in the channel map. There is an advantage to provide convenience to the consumer.
