The present invention relates to a method for integrated classification by topic of a broadcast program. In particular, a program list of various broadcasting stations received by KBPS (Korea Broadcast Pogrammer System) can be edited by topic to selectively display a desired type of program on a screen. It relates to an integrated classification method for each topic of a broadcast program.

Generally, when transmitting TV broadcasting signal, broadcasting information and other information is transmitted in the form of data in a specific area of the vertical blanking interval (VBI) of the video signal, and the receiver decodes this data. Therefore, it is used for TV viewing or necessary recording such as reservation recording of VCR. This is called KBPS, that is, broadcasting information system.

In case of using for VCR reservation recording, KBPS is a signal regulation operation plan for Korean simple reservation recording, and it can be occurred in transmitting program such as advance, delay, cancellation, change of program broadcasting time by referring to program list displayed on TV screen. By prescribing countermeasures for all possible matters, users can easily and quickly make reservations for accurate scheduled recording of programs.

The format of the KBPS data is as follows.

First, the insertion line sets an arbitrary line according to the conditions of each broadcasting station during the VBI period, and outputs data by selecting one of the even or odd fields among the set lines, and in this case, one line or two lines are used. Can be.

The clock frequency is 5.7272 MHz, the data rate is 5.7272 Mbit / sec, the data coding method is NRZ (Non Return to Zero), and one data line is 36 words, that is, 288 bits. As shown in FIG. 1, the data block includes clock and byte synchronization, a data header, and valid data.

The dual clock synchronization is a reference signal for synchronizing the data clock of the receiver, and the byte synchronization is a framing code and a reference signal of the byte synchronization.

In addition, KBPS transmission data is as follows, which is information carried in the valid data.

a. Station standard time information

b. Program information currently on air (On-Air Program information)

c. Broadcasting station name (seven characters)

d. Weekly program information (for one week-four weeks)

e. Classification data by program type

f. Accurately record only pure broadcast programs

g. Display function of changed information

h. Program Details

i. Program subtitle guide function

Meanwhile, the KBPS displays one week or four weeks of broadcast programs on a TV screen according to signal regulations, and when the user wants to record a desired program event by using a cursor, the KBPS moves to a desired program location and then program event information. Is stored in an inactive memory element in the VCR, and it is possible to proactively cope with a change in program start time due to broadcasting stations.

In addition, since the current time data is transmitted, automatic time setting and correction are possible, and contents to be recorded accurately can be reserved even when pruning or when the broadcasting time is changed.

KBPS converts the program reservation recording data into a digital signal on the TV signal, inserts it into a fixed line (16th line) in the VBI of the video signal, and transmits the demodulated signal at the decoder at the receiving end. In the program, smooth schedule recording and automatic time setting are performed.

The above-described function is performed in the hardware as shown in FIG. 2, wherein the line detector 1 detects 16 lines containing KBPS information from the input broadcast signal, which is input to the decoder 2 and decoded. .

The output of the decoder 2 is input to the overlay controller 3 so that the KBPS information is displayed on the screen.

In this case, the operations of the line detector 1, the decoder 2, and the overlay controller 3 are controlled by the microcontroller 4.

In addition, the output of the decoder 2 is input to the system control unit 5a and the servo system 5b of the VCR 5 for reservation recording, and the system control unit 5a and the servo system 5b are the microcontroller. It works in conjunction with (4).

Meanwhile, a conventional broadcasting program classification method using the KBPS information will be described with reference to the flowchart of FIG. 3 as follows.

First, by receiving and storing data sent by KBPS (S1), the data is data necessary for performing the various functions mentioned above.

After performing step S1, a classification key is input (S2), and the classification key is a key that is already installed in the remote controller of the device. If the user wants to search by classification, the user presses this key in step 3 (S3). The following procedure is performed.

All program titles have a sort code that allows you to determine what kind of program this program is. Since each station has a different classification scheme and corresponding code, it can be classified from classification data. And the classification name and the code are found. In step S3, the classification name is listed and the user is selected by the user in step S4.

Then, a code for the classification name selected in step S5 is obtained, and in step S6 a program title matching this code is shown on the screen.

However, in the conventional technology as described above, since the program classification codes are different for each broadcaster, only partial search in which a search according to a program type is limited to one channel is possible. Therefore, the user must know at least which channel the desired program is, and if not, it is a hassle to search all the channels one by one.

Disclosure of Invention The present invention has been made to solve such a problem, and an object of the present invention is to allow a program of a program of various broadcasting stations to be selectively displayed on a screen so that program selection is easier. To provide an integrated classification method.

Features of the present invention for achieving this purpose are the input step of inputting the broadcast program guide data carried on the video signal, the sorting and storing step of sorting and storing the broadcast program guide data of the various broadcast stations according to the classification scheme, and A string comparison step of comparing each character string according to the classification code with the character string according to the classification code of another broadcasting station based on one broadcasting station classification system in the stored program guide data; and the classification code of the other broadcasting station according to the comparison result. And a classification code mapping step corresponding to a classification code of a broadcasting station selected as the reference.

According to another aspect of the present invention, there is provided an input step of inputting broadcast program guide data carried on a video signal, a sort storage step of sorting and storing the input broadcast program guide data of various broadcasting stations according to a classification system, and sorted and stored broadcast program guide data. In the integrated classification method according to the subject of the broadcast program comprising a mapping step that allows the user to select any one station to match the classification system of other broadcasting stations based on the classification system of this broadcasting station.

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

First, the present invention is performed by the hardware as shown in FIG.

FIG. 4 is a flowchart illustrating the overall flow for performing the integrated classification method for the subject of a broadcast program according to the present invention. Since the classification and the codes are different for each broadcaster, all of them are received and stored in the memory (S11). In the classification map creation process, one integrated classification system is completed (S12), and a detailed description thereof will be described later.

When the classification key is pressed, the integrated classification list completed in the step S12 is shown on the screen (S13) (S14).

The user selects a desired integrated classification name, and then obtains a code of each broadcaster for the selected classification name (S15).

For example, in the case of reporting, KBS may have a code of 7, MBC, 11, and SBS of 8, which are displayed on the screen in comparison with the classification codes attached to the program titles of the respective broadcasters (S17).

On the other hand, the automatic whole classification method by comparing the classification character data is as follows.

First, in KBPS, each broadcasting station is categorized into several programs. The three broadcasting stations are shown in Table 1 below.

In Table 1, classification names such as movies and cartoons are referred to as sorting character data or sorting names in the present invention.

The classification character data are complete codes and are already defined as spets. Therefore, they can be compared programmatically, and these comparisons create a common classification table and tie the classification codes of each broadcaster to this classification.

FIG. 5 is a flowchart showing a process of creating an integrated classification map by comparing classified character data.

The number of classifications is different for each broadcaster in KBPS, and the classification system of the broadcaster having the largest classification system is selected (S21).

Taking Table 1 as an example, since the MBC has the most 12 classification systems, an integrated classification map is created using this system as the integrated classification system.

Then, in step S22, one of these classification strings is obtained. Also, if Table 1 above is taken as an example, a classification string called a movie is obtained, and this is compared with the classification strings of other broadcasts in step S23. It can be seen that it has a classification name of a string such as KBS1 and SBS broadcasters mode.

This is found by the microcontroller 4 by string comparison. In the integrated classification system, the movie is stored as number 1 for MBC, number 1 for KBS1, and number 1 for SBS.

And in the case of reporting, it can be seen that it is 11 for MBC, 8 for KBS1, and 8 for SBS, and this process is repeated 12 times by step (S24) and still does not belong to the classification map. If there is a bad classification name, it is classified in the other (S25) (S26).

In this way, the integrated classification code map is completed (S27), and in the case of Table 1, all 13 integrated classification names are generated. However, in this case of entertainment, "show", "show, entertainment" are regarded as the same character string and classified together.

FIG. 6 is a flowchart showing a process of creating an integrated classification map by a user, which is different from the above, and allows a user to select one reference broadcaster so that the classification system of another broadcaster is based on the classification system of the broadcaster. It builds a working environment to fit and puts each broadcasting company's classification system into one integrated classification map as the user wants. The process is as follows.

First, the classification system for each broadcaster is shown by listing the broadcaster names and their names as shown in FIG. 7 (S31).

At this time, the broadcaster is changed by the user's remote control or a button input of the device, and the list of classification names at the bottom is also changed.

The user selects a desired one among these classification lists (S32).

Then, in step S33, the selected list is used as the integrated classification system, and the integrated classification map preparation screen as shown in FIG. 8 is collected.

Then, the classification name is changed with the numeric buttons, and the classification name of another broadcasting station to be placed under an arbitrary integrated classification name is assigned (S34). .

And the classification names of other broadcasters appear in the space below, and change these names so that they appear to be of a similar kind in the blank, and then press the set button to complete the integrated classification map (S35).

If the integrated classification name is Show in the example of FIG. 8, KBS1 is Show, MBC is Entertainment. And when SBS integrates shows and entertainments, and later selects a show in the entire search, the microcontroller 4 will enter a program classified as a show in KBS1 and entertain in MBC. In addition, all the programs classified as “Shows, Entertainment” in SBS are displayed.

As described above, the present invention edits program lists of various broadcasting stations according to themes and selectively displays the kinds of programs desired by the user on the screen. It solves the disadvantages that were allowed, and thus allows the user to use KBPS more efficiently.
