Description

Information display control method using GPS data

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for controlling display of GPS information. More particularly, the present invention relates to an information display control method using GPS data for displaying field-specific information added to the GPS on a screen separately from the screen display for reservation recording.

The Korean Broadcasting Program System (GPS) is an example of a data broadcast in which data encoded by a broadcasting station is loaded on a broadcast signal and transmitted in order for a user to easily use information about a broadcast program according to a reserved recording or broadcast time.

In general, each broadcasting station transmits only broadcast program information transmitted from its own broadcasting station on the broadcasting signal of the corresponding channel.

Accordingly, when the broadcast signal receiving side receives a broadcast signal of a specific channel while the broadcast signal is turned on, the K key is immediately turned on to display the broadcast program only by the GPS data of the received channel on the screen.

That is, in the conventional GPS technology, only the broadcast program information is included, and the VCR to be received according to the time of the corresponding broadcasting station is used when the user wants to perform the scheduled recording using the immediately K screen for displaying the GPS data. Program information is displayed.

Therefore, there is no control function for classifying and displaying various information such as news and life information other than broadcast program information, and there is a problem in that information cannot be used in various ways.

The technical problem to be solved by the present invention is to solve the above problems, after the broadcasting station adds the field-specific information such as news and life information other than the broadcast program information to the WPS transmission data, and then uses the information added to the WPS. To provide an information display control method using the GPS data to display on the screen.

1 is a flowchart of an information display control method using GPS data according to the present invention.

2 is a block diagram of a VCR device to which the present invention according to FIG. 1 is applied.

In order to achieve the above technical problem, in the information display control method using the GPS data according to the present invention, the bulletin board data for the information of each sector is added in addition to the program data for the information about the broadcast program, and the information for each sector using the GPS signal transmitted. A control method for displaying a message, the control method comprising: receiving a WPS signal, classifying the program data and the bulletin board data, and storing the stored bulletin board data by a bulletin board data storage step and a bulletin board information display command. And displaying the bulletin board information to be displayed on the screen.

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

As shown in FIG. 1, in the information display control method using the WPS data according to the present invention, a WPS data extraction step 110 for extracting only the WPS data contained in a video signal, separating the data into field data among the WPS data, is performed. Data separation step 120, data storage step 130 for storing data for each field in the area allocated to each of the memory, setting command determination step 140 for determining whether the bulletin board information display command is set, the field of the field to be displayed An information storage determination step 150 for determining whether information is stored, a data read step 160 for reading data stored in the memory, a conversion step 170 for converting the data into a text signal, and a display of the converted text signal Display step 180 is provided.

Before describing the detailed flowchart of the present invention, FIG. 2 will be briefly described with reference to FIG. 2, which is a block diagram of an apparatus having a system controller 240 and a memory controller 220 to which the method of controlling the flowchart of FIG. 1 is applied.

The PSP information display control apparatus of the VCR to which the present invention according to FIG. 2 is applied performs a data slicer 210 for extracting only the PPS data contained in the vertical blanking interval of the demodulated video signal, and the control for writing / reading the PPS data into the memory. A memory controller 220 for storing data, a memory 230 for storing data, a system controller 240 for controlling blocks of the system, a character converter 250 for converting data into a text signal, and a converted text signal and a video output And a display unit 260 for synthesizing and displaying the signals.

Each step of FIG. 1 will be described in detail with reference to the block diagram of FIG. 2.

The PPS data extracting step 110 extracts only the PPS data contained in the vertical blanking interval of the video signal input by the data slicer 210.

The data separation step 120 is a step of decoding the WPS data extracted by the memory controller 220 to separate the data for the broadcast program information and the data for the inserted bulletin board information added by the broadcasting station.

In addition, data on bulletin board information is classified into detailed fields such as news, boundary, society, culture, sports, and health.

The data storing step 130 stores the broadcast program data and the data for each field separated in the data separating step 120 in respective allocated areas of the memory 230.

The setting command determination step 140 is a step of determining whether a bulletin board information display mode is set for displaying information for each sector additionally loaded in the GPS by a user's key input.

The information storage determination step 150 is a step of determining whether data regarding information of a field selected by a user is stored among information other than broadcast program information in the memory 230, and data for information on the selected field is stored. If so, the data read step 160 is executed, otherwise, the step ends.

The data read step 160 is a step of reading data of a memory 230 area in which data about information of a selected field is stored according to a set bulletin board information display specification.

The converting step 170 converts the data of the selected field read from the memory 230 into a text signal by the text converting unit 250 and outputs the text signal.

The display step 180 is a step of displaying information on a selected field converted into a text signal on a screen. For example, roll play of characters on the selected information input at the bottom of a screen set to display bulletin board information. Display in form.

Through the above steps, the broadcasting station separates the data for each field added to the GPS data and stores them in the designated areas of the memory, and when a command for displaying these information is set, the data for the selected information allocated and stored in the memory is read. By pulling out and displaying on the screen, the user can easily obtain various information.

As described above, according to the present invention, the broadcast station receives data transmitted together with data about various information other than the broadcast program data of the WPS, separates and stores these data for each field, and stores the stored data for each field to the user's selection. Therefore, by displaying, the user can obtain various information by using the GPS data.
