Description

Order information service method by individual in digital satellite broadcasting system}

The present invention is a condition set by the subscriber in the service that must provide a large amount of data in real time, such as stock information in the digital satellite broadcasting system, or services that must provide different information according to the region where the subscriber is currently located, such as weather information A personalized personal information service method capable of providing information (personalized information) that satisfies a (personalized condition), and a computer-readable recording medium having recorded thereon a program for realizing the method.

In general, users want to easily and conveniently obtain useful information such as stock situation, road traffic situation, shopping / advertisement, sporting event situation, etc. Getting the information you want with their search capabilities is not only easy, but also takes a lot of searching time. In order to solve this problem, Internet information portal sites are equipped with search engines that can search their database for the convenience of users, but it is not only difficult to obtain the necessary information quickly and accurately, but also takes a lot of time and effort. There is discomfort that should be.

That is, information located beyond time and space can be accessed through a communication network, and each user finds an information source (content provider (CP)) where desired information is located through a wired or wireless terminal and a communication network, and directly accesses the desired information. Will be taken. However, this general information acquisition method is very inconvenient to quickly grasp the information to be converted over time. In addition, even after accessing the information source, it is inconvenient to select specific information items desired by the user or to obtain customized information through a separate logical, computational or speculative processing process.

As an example of general information acquisition, if you want to know the latest information of stock information fluctuating from time to time, frequently connect to the system that provides stock information through the communication network, or connect or disconnect between the stock information system and the user's terminal. You should establish a connection and continue to observe the information unilaterally provided by the server system.

Another example is when you want to know the traffic situation at a certain time each morning. The user must repeatedly access the traffic information providing system at a specific time every day to obtain the desired information through a series of processes.

Such cases of inconvenient information acquisition are all cases where changes are made to information that is periodically or aperiodically transformed over time, or only the information that satisfies certain conditions (eg, stock situation, road traffic situation). , Shopping / advertisement, sporting events, logistics and delivery status, work schedules, etc.), in which case general information acquisition methods are very inconvenient and time-consuming and economical.

This uncomfortable problem in the general information acquisition method is not limited to the information acquisition through direct access to the information source (content provider (CP)), especially in digital satellite broadcasting system.

Since digital satellite broadcasting such as DAB / DMB (Digital Audio / Multimedia Broadcasting) is a broadcasting service, it is impossible to selectively select and receive subscriber-specific personal information from an information terminal (mobile phone, PDA, etc.). There is a limit to receiving personalized services.

Although bidirectional services have been mentioned as DAB (or DMB) digital satellite broadcasting is now being specified, this bidirectional service also transmits data first in a broadcast transmission system and thus responds to information terminals. With such a service structure, there are limitations to realize personalized customized information service.

As described above, in the DAB (or DMB) digital satellite broadcasting system, only data limited to one subscriber cannot be selectively transmitted, and all data is transmitted in common. Therefore, especially when there is a large amount of information to be provided in real time, such as stock information, the information terminal having a limited size of the display device (that is, the information terminal is a small terminal with emphasis on mobility, so the screen for displaying information is also small. ) Is not only difficult to find the desired information but also inconvenient because many items exist in retrieving the data of the same stock item repeatedly, and among the many data provided by DAB (or DMB) digital satellite broadcasting system, There is an urgent need for a way to provide only information. In addition, when different information needs to be provided according to the region where the subscriber is currently located, such as weather information, there is a way to provide only the information desired by the subscriber among many data provided by the DAB (or DMB) digital satellite broadcasting system. It is also required.

The present invention has been proposed in order to meet the above demands, and in particular, in a digital satellite broadcasting system, a service having to provide a large amount of data in real time, such as stock information, or a different location depending on the region where the subscriber is currently located, such as weather information. Personalized information service method for providing only information (personalized personalized information for each subscriber) that meets the conditions (customization conditions) set by the subscriber to the information terminal that is limited by the size of the display device in the service to provide information, and It is an object of the present invention to provide a computer-readable recording medium having recorded thereon a program for realizing the method.

By receiving the, it is possible to implement a personalized information service for each subscriber.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a digital satellite broadcasting system to which the present invention is applied, and shows a system configuration for implementing a DAB (or DMB) digital satellite broadcasting service.

As shown in FIG. 1, the streaming data provided by the information provider 11 is compressed / multiplexed by the information server 12 and the broadcast control server 13 (Ku-band (13.824-18.849 GHz) (TDM), Ku-band (13.858 to 13.883 GHz) (CDM), and is transmitted to the satellite body 108 through the broadcast transmitting base station 14, and the satellite body 18 performs frequency conversion on the received streaming data (TDM / CDM signal) ( Ku-band (12.214 ~ 12.239GHz) (TDM) and S-band (2.630 ~ 2.655MHz) (CDM) will be sent to the ground. At this time, the streaming data transmitted to the ground is received by the signal conversion repeater (Gap Filler) 15 or directly in the information terminal (mobile communication terminal, PDA, vehicle terminal, etc.) 19. Therefore, the signal conversion repeater 15 receives the satellite TDM signal (Ku-band (12.214-12.239 GHz) (TDM)) and converts it into a CDM signal (S-band (2.630-2.655 MHz) (CDM)). It transmits to the terminal 19, the information terminal 19 demodulates the streaming data (CDM) received directly from the satellite 18 or through the signal conversion repeater 15 to output the broadcast information to the subscriber.

The information terminal 19 may be a mobile communication terminal such as a laptop, personal digital assistants (PDAs), cellular phones or PCS phones, or an international mobile telecommunication (IMT-2000) or universal mobile telecommunication service (UMTS). It may be a next generation mobile communication terminal, a vehicle terminal and the like.

However, since the mobility of the information terminal 19 is the center, it is inevitably limited to the size of the device displaying the information. Therefore, since there is a large amount of data such as stock information generated in real time received above, it is difficult to display all of the stock information. That is, in the case of securities information, the stocks of interest by the number of securities stocks should be operated by the subscriber to input the code value using the keypad.If the channel is selected again after the channel change, the stock code is input again. There may be inconveniences such as having to. Therefore, the following will be described in more detail with respect to a solution that can eliminate this inconvenience.

Since the DAB (or DMB) digital satellite broadcasting service can accommodate many broadcast channels, the information terminal 19 can select a channel that the subscriber wants to watch.

First, the information server 12 processes and generates a large amount of securities information provided in real time from the information provider 11 through the data encoding and compression process to the optimal data in order to increase the efficiency of data transmission. The generated data is subjected to a multiplexing operation like video / audio data in the broadcast control server 13.

Thereafter, the multiplexed data is transmitted to the satellite 18 by the broadcast transmitting base station 14, and the satellite 18 sends the received broadcast data back to the ground with different bandwidths, thereby transmitting the information terminal 19. ) Receives broadcast data directly from the satellite 18 or broadcast waves transmitted from the signal conversion repeater 15 in the satellite reception shadow area.

At this time, when the subscriber selects the securities broadcasting service channel in the information terminal 19, the information terminal 19 is digital satellite broadcasting received from the satellite 18 or the signal conversion repeater 15 through the selected corresponding data service channel. Will be received.

When the service channel is selected, in order to extract only information corresponding to the set personalized information among digital satellite broadcasts received through the corresponding service channel, it is checked whether the personalized information is set. At this time, the customized information is set for each subscriber in the DB of the information server 12, the subscriber may be registered in the information server 12 via the mobile communication base station SMS server 16 through the information terminal 19, It is obvious that the information terminal 19 or other wired / wireless internet access terminal may be registered by accessing a web / web page through the wired / wireless internet. The customized information is, for example, a stock item code value and a stock name, and is stored in a text form in a DB of the information server 12. There may be a limit to the number of custom stocks a subscriber can register.

The request for confirming the setting of the customized information is generated in the information terminal 19, and is transmitted to the information server 12 via the mobile communication base station 17 and the SMS server 16, and the information server 12 is set by the subscriber. The customized information is placed in the DB and transmitted to the information terminal 19 via the SMS server 16 and the mobile communication base station 17.

Then, the information terminal 19 selects only the stock items that are set as the personalized information among a large number of stock information generated in real time through the broadcasting channel using this personalized information, and the information such as the current price, the bid price, the bid price, the total sale volume, etc. It is possible to directly perform stock trading by providing a communication channel.

The transmission and reception message structure between the information terminal 19 and the information server 12 is as follows.

Subscriber ID Service code Parameter (Length≥0)

Here, the subscriber ID is a unique value that can distinguish the subscriber from other subscribers, and may be a phone number and a unique terminal number.

The service code is a service identification code for whether the corresponding message is stock custom information or SMS.

In addition, the parameter field contains necessary data according to the service code. That is, when the stock terminal requests the stock information from the information terminal 19 to the information server 12, the message sent from the information server 12 to the information terminal 19 includes N stock item codes registered by the subscriber with the customized information. Will be loaded.

In the above, after confirming that the personalized information is set, if the personalized information is set, the information terminal 19 receives the personalized information set by the subscriber from the information server 12 and stores it in the internal memory. However, if the personal information is not set in the DB of the information server 12, the subscriber directly inputs the stock item code value by using the keypad, and the entered item code value is used in the information terminal 19. It is stored in internal memory.

The information terminal 19 stores the stock code information input by using the set personalized information or the keypad in the internal memory, and then demultiplexes the received broadcast data to separate data such as video / audio and text data signals. do. At this time, the separated and extracted character data is decompressed through the data decoding operation and restored to the original stock information data. Of the restored data, only the corresponding stock item data is extracted according to the stock item code, which is stored in the memory, and the extracted stock information data is displayed on the display device of the information terminal 19.

In this way, the personal information is stored in the information server 12, and data communication is performed between the information terminal 19 and the information server 12, so that many stock services occur in real time in the DAB (or DMB) digital satellite broadcasting service. In the personal information service can be provided.

2 is a flow chart of an embodiment of a personalized personal information service method according to the present invention.

Basically, since the DAB (or DMB) digital satellite broadcasting service can accommodate many broadcast channels, the information terminal 19 can select a channel that the subscriber wants to watch.

As shown in FIG. 2, in the personalized personal information service method according to the present invention, first, a large form of securities information provided in real time from the information provider 11 in order to increase the efficiency of data transmission in the information server 12 in binary form. Through the data encoding (compression) process of the processing to generate the optimum data (201, 202). The generated data is subjected to multiplexing by the broadcast control server 13 like video / audio data (203).

Thereafter, the multiplexed data is transmitted to the satellite 18 by the broadcast transmitting base station 14 (204), and the satellite 18 sends the received broadcast data back to the ground with different bandwidths.

If the subscriber selects the securities broadcasting service channel in the information terminal 19 (205), the information terminal 19 receives broadcast data directly from the satellite 18 via the selected data service channel or satellite propagation. In the reception shadow area, the broadcast wave transmitted from the signal conversion repeater 15 is received (206).

Thereafter, in order to extract only desired information among digital satellite broadcasts received through the service channel, it is checked whether personalized information is set (207).

Since the personalized information is set for each subscriber in the DB of the information server 12, the personalized information setting confirmation process, as shown in FIG. 3, causes the information terminal 19 to send the personalized information setting confirmation request message to the mobile communication base station 17. And when sending to the information server 12 via the SMS server 16 (301), the information server 12 inquires the customized information set by the subscriber in the DB (302), if the customized information is set In step 303, the personalized information is transmitted to the information terminal 19 via the SMS server 16 and the mobile communication base station 17 (304). Then, the information terminal 19 receives the customized information from the information server 12 and stores it in the internal memory (305). However, if the personalized information is not set, the information server 12 transmits (306) a message (personal information setting confirmation result message) indicating that the personalized information is not set.

If the personal information is not set in the DB of the information server 12, and the user receives a message (the personal information setting confirmation result message) indicating that the personal information is not set from the information server 12, the subscriber uses the keypad. The stock item code value must be input directly (209), and the input item code value is stored in the internal memory of the information terminal 19.

Next, the information terminal 19 stores the stock code information input by using the set personalized information or the keypad in the internal memory, and then demultiplexes the received broadcast data to receive data such as video / audio and text data signals. In step 210, the extracted extracted character data is decompressed through a data decoding operation and restored to original stock information data (211).

Subsequently, the information terminal 19 extracts only the corresponding stock item data according to the stock item code which is the customized information stored in the memory among the restored data (212), and displays the extracted stock information data on the display device (213). ).

In the above process, after receiving the broadcast data (206), and confirming and inputting the custom information setting process (207 ~ 209) as an example, but after receiving the broadcast data (206) after performing the demultiplexing and decoding process (210,211) Obviously, the same result can be obtained by performing the checking and inputting of the personalized information setting process (207 to 209).

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention provides a personalized personalized information service for each subscriber by providing information in real time according to a history set by an individual, while the information terminal communicates with the information server and escapes from a uniform broadcasting service.
