Description

Method for sorting broadcasting channels

The present invention relates to a method for sorting a broadcast channel, and in particular, when setting a channel of a program transmitted for each broadcast station in satellite broadcasts and all broadcasts, the same channel number is used regardless of the region using information data stored in a memory. The present invention relates to a broadcasting channel sorting method for viewing a program of a broadcasting station name.

The conventional broadcast channel automatic setting method,

A first step of initializing the data of the tuner, a second step of retrieving the presence of a signal if the initialized tuner data is not last, and broadcasting station information contained in the vertical retrace period (VBI) if there is a signal in the step. And a fourth step of decoding and storing the data, and a fourth step of increasing the data of the tuner after the step and outputting the data to the tuner.

This will be described in more detail with reference to FIG. 1. 1 is a flowchart illustrating a conventional method for automatically setting a broadcast channel.

Referring to FIG. 1, when a broadcast channel automatic setting command is given, the microcomputer (not shown) initializes the tuner data (step S11) and determines whether the tuner data is the last (step S12). In this determination, if the tuner data is the last, the program is terminated. If not, the program is searched for whether there is a video signal (step S13).

If there is a video signal as a result of the search in step S13, after reading and decoding the broadcast station information included in the vertical blanking interval (VBI), the decoded broadcast station name is stored (step S14).

If there is no signal at step S13 or after broadcasting station information is stored at step S14, the data of the tuner is increased (step S15) to output data to the tuner (step S16).

By increasing the tuner data in this process, whenever there is a signal, broadcasting station information included in the vertical retrace period (VBI) is decoded and stored to store broadcasting station names for all broadcasting channels in channel units.

Here, the vertical retrace period (VBI) is a period that does not affect the video signal, in which information related to a broadcasting station (own broadcaster's unique number) and information relating to time zone broadcasting are transmitted.

On the other hand, the conventional broadcast channel setting method as described above is able to automatically store the broadcast station name when a signal is received, but there is a problem that is displayed in the order of the unwanted broadcast channel when changing the program-related channel.

In addition, for example, in Korea, broadcast channels in Korea have different channel information for each broadcasting station, so when a user moves and moves a region, it is not easy to know how many times each broadcasting station is.

In other words, even if the broadcast channel is set automatically, it is stored in units of channels, so if the region is moved, it takes a little time to know the channel of each broadcasting station.

As described above, since the broadcasting channel automatic setting program is stored in the order of the broadcast channels in which the signal is received, the conventional broadcasting channel is stored in the same broadcasting channel even after moving to a certain area. It is impossible to watch the program.

The present invention has been made to solve the above-mentioned conventional problems,

The purpose of the present invention is to provide a broadcasting channel sorting method in which broadcasting station names are automatically sorted in the order of priority set regardless of region, and when a viewer selects a desired country or language, the ranking of the corresponding country or language is assigned first.

Provide,

The second feature is to store the information and priority of broadcasting stations in memory and to reassign priorities using a specific medium (language or country) so that the station name of the country to which a specific medium (language or country) is assigned is first stored. On the other hand, by providing information on a specific medium (language or country) on the screen for the viewer to select before the automatic program start to provide a more convenient to the viewer.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. 2 is a flowchart illustrating an execution process of a first embodiment of a broadcast channel sorting method according to the present invention.

Referring to FIG. 2, the data of the tuner is initialized at the start of the automatic program, and it is determined whether the data of the tuner is the last. If the data of the tuner is not the last, the presence or absence of the video signal is searched. S301, S302, S303)

In step S303, if there is a video signal, the broadcasting station information contained in the vertical blanking interval VBI is detected. If there is no signal, the tuner data is increased to output the data to the tuner to sequentially tune channels of each broadcasting station. do. (See S304, S308, S309 in Fig. 4)

In this case, the priority of the broadcasting station information detected in the step S304 is read from a memory (eg, ROM) to find the broadcasting station name and the sorting priority data corresponding thereto, and the broadcasting station name is stored in the main memory. (Sorting order) is backed up to the external memory. (See S305, 306, 307 of FIG. 4) For reference, the 'priority' in the 'priority', 'sorting priority', and 'sorting priority' is basically stored in broadcasting stations and other information stored in the memory (ROM). 'Sorting Priority' refers to the rank that is stored in the main memory along with the corresponding priority when the video signal is detected in the automatic program execution stage. The "sorting order" refers to the priority itself corresponding to broadcasting stations and other information. For example, when the priority corresponding to KBS1 is 0, the sorting order of KBS1 is 0.

Here, the data structure of the memory is divided into information on broadcasting station name and information on its priority, and the relationship between data and priority on broadcasting station name is assigned with the highest priority for the first national broadcasting of each country. It is. (For example, KBS1 is priority 1, KBS2 is priority 2, ..., etc.)

By increasing the data of the tuner in this order, whenever there is a signal, the station name is stored in the sorting order stored in the memory (ROM) and the sorting order is backed up to the auxiliary memory until the tuner data is finished. Will continue. That is, before the automatic program termination, only the data for the priority is stored without re-sorting the priority.

When the data of the tuner ends and the automatic program ends, in the sorting routine execution step (S310), the broadcasting station names are sorted according to the stored sorting order, and the broadcasting station names are sorted according to the priorities stored in the memory (ROM). do.

Therefore, data having a specific priority with respect to broadcasting station information and the priority of the data are stored in the main memory and sorted according to the broadcasting station name and sorting priority so that the same broadcasting channel name can be identified using the same program channel in any region. .

That is, if the first priority is given to the first national broadcasting (eg KBS1), the first national broadcasting is automatically sorted to the highest priority (eg KBS1 → KBS2 → KBS3, ...) and displayed on the screen. If you give priority to a specific language or country, that language or country will have the highest priority.

FIG. 3 is a flowchart showing an execution process of the second embodiment of the broadcast channel sorting method according to the present invention. FIG. 4 is an on-screen display of an automatic program menu in the present invention.

3 and 4, when the automatic program is started, the display is displayed on the OSD screen so that the viewer can select a specific medium (language or country) (S311 of FIG. 3).

For example, as shown in FIG. 4 (a), the viewer displays a language such as Korean, Japanese, and Chinese on the OSD screen, and the viewer selects a specific language (eg, Japanese) as shown in FIG. 4 (b). 4 (c), a country such as Korea, Japan, China, etc. is displayed on the OSD screen so that the viewer selects a specific country (eg, Japan) as shown in FIG. 4 (d).

When the viewer selects a specific medium (language or country) while viewing the OSD screen, the microcomputer initializes the tuner data and then searches for the presence or absence of an image signal if the tuner data is not the last (S312 in FIG. 4). S313, S314)

If there is a video signal as a result of the search in step S314, the broadcasting station information contained in the vertical blanking interval VBI is detected, and the broadcasting station name for the detected broadcasting station information is found in the memory (e.g., ROM). S315, S316)

At this time, it is determined whether the broadcasting station name read from the memory ROM is a broadcasting station using a specific medium selected by the viewer (S317). That is, in step S311, it is determined whether the broadcasting station uses the language selected by the viewer or the broadcasting station in the country selected by the viewer.

Then, if the broadcasting station uses a specific medium, the sorting order of broadcasting station names is determined according to the sorting of the memory (ROM) (S318), and if the broadcasting station using a specific medium is added, a constant value (N) is added to the sorting of the main memory. The sorting order is determined (S319).

For example, if data is read from the memory (ROM) and then the language is selected as Korean on the OSD, and the captured signal is NHK1 broadcast, the priority (priority + N + N) is added to the priority of the memory (ROM) by adding a certain value (N). ),

In addition, if the country is selected as Korea on the OSD after the data is read from the memory, and the captured signal is NHK1 broadcasting, which is a Japanese national broadcaster, the priority (priority + N) is reassigned by adding a constant value (N) to the memory priority. .

Here, N is the priority of the lowest priority among Korean broadcasting stations, and since the highest priority among the broadcasting stations is designated as 1, the actual priority (reassigned priority) is high even if the NHK1 broadcasting station has a high priority. Ranking) will be lower than that of any broadcasting station in Korea.

When the sorting order is determined in the above steps (S318 and S319), the broadcasting station name is stored in the main memory, the allocated sorting order is backed up in the auxiliary memory, and the data is output to the tuner while increasing the data of the tuner. The program will continue to run automatically. (See S320, S321, S322 in Fig. 3)

By increasing the data of the tuner in this manner, whenever a signal is received, the station information is read from the memory (ROM), and the station name and sorting order are stored while following the priority according to a specific medium (language or country) selected by the viewer.

After the automatic program is terminated using the stored broadcasting station name and the backed up sorting order according to the above priority, the broadcasting station name is recorded in the auxiliary memory according to a specific medium (see S310 of FIG. 3).

Therefore, by storing the information and priority of broadcasting stations in the memory (ROM) and reassigning the priorities according to specific media such as language or country, the broadcasting station name of the country where the language or country is assigned has priority. Be sure to

FIG. 5 is a flowchart illustrating a resorting routine after completion of an automatic program according to the present invention, and FIG. 6 is a view illustrating a state in which a broadcasting station name is stored according to a sorting order employed for implementing a broadcasting channel sorting method according to the present invention. .

5 and 6, first, the start pointer and the counter are initialized in the sorting order stored in the main memory, and the priority of the broadcasting station stored in the memory ROM is read (see S331 and S332 of FIG. 5). )

Then, it is determined whether the start pointer is the end (S333), and if it is not the end, the start pointer is increased, and the sorting rank (A) indicated at this time is used as the start pointer (S334), and the counter is incremented to catch the entire program (PR). If not equal to the above, the priority of the counter is read, and the sorting priority B is set as the counter value (S335 to S338 in FIG. 5).

The sorting order B indicated by the counter read in step S338 is compared with the sorting order A indicated by the start pointer (S339). When the sorting order indicated by the counter is large, Through the steps S335 to S338, the counter is incremented and compared with the read sorted rank.

However, when the sorting rank B indicated by the start pointer is greater than the sorting rank A indicated by the counter as a result of the comparison in step S339, the broadcasting station names corresponding to the sorting ranks are exchanged (S340).

After that, when the counter equals the total number of programs (PR), the counter is initialized (S341) and the start pointer is increased (S334). Change it accordingly.

After this procedure, the broadcasting station names are sorted in the sorting order stored in the memory ROM, and the broadcasting stations are stored in the auxiliary memory.

Referring to FIG. 6, the sorting routine of FIG. 5 is stored in the sorting order stored in the main memory 100 in the order of 3 → 4 → 1 → 6 → 7 → 8 → 9 → 0 → 5 → 2 → 10. If a station name corresponding to the sorting order is stored in the auxiliary memory 200 in the order of KBS3 → KBS2 → KBS1 → KBS4 → KBS5 → KBS6 → KBS7 → KBS8 → KBS9 → KBS10 → KBS11, respectively, after sorting is completed. The stations should be sorted in order of sorting rank from 0 to 10.

For example, the sorting order and station name indicated by increasing the start pointer is 3, KBS3, and when the counter is increased, the sorting order and station name indicated by the increased counter is 4 and KBS2.

As a result of the comparison, the counter is increased again because the sorting rank indicated by the start pointer is high (3 <4), and then the stations of KBS3 and KBS1 are sorted because the sorted rank 3 indicated by the start pointer is larger than the sorted rank 1 indicated by the counter. Replace the names with each other.

At this time, the data of the broadcasting station name of the changed auxiliary memory 200 is in the order of KBS1, KBS2, KBS3, ..., KBS11.

After continuing the sorting process, the sorting completion structure shown in Fig. 6, that is, KBS8 (0), KBS1 (1), KBS10 (2), KBS3 (3), KBS2 (4) and KBS9 (5) KBS4 (6), KBS5 (7), KBS6 (8), KBS7 (9), and KBS11 (10) are stored in a sorted state in the secondary memory 200 in this order.

Therefore, when a signal is detected during the automatic program, the sorting priority is stored in the main memory 100 and the broadcast station name corresponding thereto is stored in the auxiliary memory 200.

Therefore, since the information and the priority of the broadcasting station are stored in the memory (ROM) area and the broadcasting station name is sorted using the priority, the same broadcasting station can be identified by the same program number in any region.

As described above, according to the broadcasting channel sorting method according to the present invention, if an automatic program is executed without recognizing the concept of a channel, it is automatically sorted in the order of broadcasting station names having the same priority from an arbitrary channel number. When moving to any region, the same channel number can be confirmed with the same channel number. Thus, it provides more convenience to the user.

In addition, when a viewer selects a specific language or country using the OSD, the selected broadcasting station is ranked first so that the local broadcasting station can be selected first.
