The present invention relates to a POI service transmission and reception system and method including TPEG-based coupon information, and more particularly, POI-related coupon data through a DMB broadcast channel (data channel) while maintaining compatibility with TPEG-based POI services. By transmitting only the information on whether the coupon service is available through the DMB broadcasting channel, or the actual coupon data through the return channel according to the user's request, while maintaining compatibility with the existing TPEG protocol, various forms of high value added The present invention relates to a coupon service providing system and a method thereof associated with a TPEG-based POI service.

1 is a diagram illustrating a conventional method for transmitting TPEG data using various transmission media. 2 is a diagram illustrating a conventional traffic and travel information source and a TPEG service transmission method. Hereinafter, general contents of the TTI service will be described together with reference to FIGS. 1 and 2.

As illustrated in FIG. 1, the TPEG protocol developed to provide traffic and travel information in various communication media, particularly digital broadcasting networks, has a delivery system of the type shown in FIG. 2. Point-of-Interest (POI) service in the TTI service area provides high value-added information on POIs such as travel information, cultural information, public facilities, accommodation, medical care, etc. that are required for drivers, pedestrians, or those who want to go to a specific destination. Of course, it is possible to provide a two-way coupon service.

In addition, as shown in Figure 2, the traffic and travel information (TTI) can be delivered by a variety of transmission media, such as FM radio broadcasting, the Internet, mobile communication, but the information delivered at this time ensures time constraints and accuracy In order to do this, the standardized system should be selected and edited. Therefore, the basic system of transport and travel information (TTI) transmission can be divided into information sorting, editing, and transmission work.

In general, digital broadcasting (digital television broadcasting, digital satellite broadcasting, digital audio broadcasting, etc.) systems include multimedia such as traffic and travel information (TTI), electronic program guide (EPG), and game contents. Data broadcast service is provided or planned to be provided. Here, TTI service is a notable field in terms of economic ripple effect and information utilization in the future, and noteworthy reasons include an increase in the number of automobiles and an increase in demand for traffic and travel information due to a five-day workweek.

The TPEG (Transport Protocol Expert Group) protocol, developed to meet these demands, aims at providing efficient traffic and travel information, especially using digital broadcasting systems. However, the only TTI application services defined by the specification to date are RTM (Road Traffic Message) and PTI (Public Transport Information). Currently, parking information (PKI), congestion and travel time information (CTI) within the TPEG forum are available. Standardization of new services such as Travel Time Information (WEA), Weather (WEA) and Environment Information Alerts (EIA) is underway.

In 1997, the European Broadcasting Union (EBU) formed the B / TPEG project group to develop a new protocol for transporting traffic and travel information in a multimedia environment. One year later, the B / TPEG group officially published the specifications for TPEG-SSF (Part 2) and TPEG-RTM (Part 4). Here, TPEG-SSF is used in the entire TPEG application and describes grammar, sentence, and frame structure, and TPEG-RTM is a standard for transmitting a traffic information message.

CEN TC 278 WG 4 formed a project group that included B / TPEG members and, since 1999, worked simultaneously to develop two specifications (Part 3 and Part 1) to support the service. The TPEG-SNI (Part 3) describes information about services and networks, and the TPEG-INV (Part 1) defines information management for prefaces, numbering systems, and development versions.

In April 2000, the B / TPEG Group published the revised standards for parts 1 to 4, and in November 2001, the TPEG-Loc standard, a reference to location information, and the TPEG-PTI Part 5) The specification is defined.

TPEG can be applied to various digital transmission media having an appropriate hierarchy, and TPEG messages are used to transmit TTI information from the service provider's database to the user's terminal.

The TPEG specification documents defined so far are:

-TPEG-INV (Part 1): management of preface, numbering system and version

TPEG-SSF (Part 2): Definition of the syntax, semantics and frame structure of TPEG.

-TPEG-SNI (Part 3): Definition of information management for service and network information

-TPEG-RTM (Part 4): Structure definition for road traffic information transmission

-TPEG-PTI (Part 5): Definition of structure for transmission of public transport information

-TPEG-Loc (Part 6): Structure definition for transmitting related information and linked location information

As mentioned in the TPEG Forum, the conventional TTI service technology provides efficient traffic and travel information using various transmission media such as DMB systems and the Internet, which adds new functions without disturbing the operation of the previous receiver or decoder. Or by modifying the protocol, it can be widely used in applications that require efficient information transmission to one-to-many, especially through broadcast systems, and one-to-one. It is also suitable for to-one or multicast applications and is intended to be compatible with Internet protocols.

However, the conventional TTI service technology is being standardized on new services such as parking lot information (PKI), congestion and travel time information (CTI), weather information (WEA), and environmental pollution warning (EIA). There was a problem that the service is provided only to traffic information such as defined RTM and PTI.

Therefore, in order to meet the needs of information users for location-based services and services linked with them, and to overcome the limitations of existing TPEG's RTM and PTI services, digital broadcasting while maintaining compatibility with application services defined in TPEG. There is an urgent need for a new TTI service plan that can effectively serve channels.

In particular, one-way and two-way coupon services associated with POI are not provided among various types of high value-added TTI services. Conventional coupon service technology is provided only on off-line or a specific website and is provided regardless of the POI service. Therefore, there is an urgent need for a method of providing a coupon service, which is provided regardless of the current POI service, in connection with the TTI service, which is limited to traffic information.

The present invention has been proposed to meet the above requirements, while maintaining compatibility with TPEG-based POI services, transmitting POI-related coupon data through a DMB broadcast channel (data channel), or through a DMB broadcast channel.

By extracting the data from the list, the service is provided where the driver or pedestrian using the receiving terminal (navigation system) is located, eliminating the unnecessary data processing process, and providing fast and accurate POI (coupon) data. (Screen output and / or audio output).

9 is a flowchart illustrating an example of a coupon information processing process in a coupon service providing method associated with a TPEG-based POI service according to the present invention. Hereinafter, the coupon information processing process will be described.

TPEG broadcast stream reception is continuously performed from the start of reception (navigation) to the end point, and the message ID and version are checked and loaded into each component list.

First, prior to describing the processing of the POI (coupon) stream, the TPEG broadcast stream will be described. The TPEG broadcast stream is a continuous flow of data that can be received through a broadcast communication network in which data such as coupon information in the POI is continuously propagated. The TPEG broadcast stream becomes useful information that can be stored while the receiving system (navigation system) is operating. However, when the receiving system (navigation system) is terminated, it is only a flow of unnecessary data that cannot be stored. However, traffic information included in the TPEG broadcast stream may be loaded in the RTM list or the PTI list, which is not discussed in the present invention.

First, when a reception system (navigation system) is started by a user, the broadcast stream receiver 810 initializes a variable for the TPEG module receiving the broadcast stream (904) and performs a command to start the broadcast stream reception. Is activated (906). In this case, the broadcast stream receiver 810 is controlled by the controller 850.

Thereafter, the receiver executes a reception thread for the operation of the broadcast stream reception module (908), and the reception thread analyzes the TPEG broadcast stream (910) and adds the received frame to the list (912). Referring to the process of adding the received frame to the list in detail, if each frame is decoded and POI (coupon) data according to the frame message ID (914) and stored in the POI (coupon) list (916). If it is LOC data (918), it is stored in the LOC list (920), and if it is SNI data (922), it is stored in the SNI list (924).

Subsequently, while the user uses the service, the reception thread repeatedly analyzes the broadcast stream and stores it for each list, and when the user terminates the service (928), the reception thread terminates reception of the broadcast stream (930). In step 932, the receiving device (navigation) is terminated.

FIG. 10 is a flowchart illustrating a process of calling coupon information in a coupon service providing method associated with a TPEG-based POI service according to the present invention, and is loaded by checking whether there is desired POI (coupon) information among received broadcast streams. The component list can be called to provide POI information. Looking at the coupon information call process as follows.

As described above, the global list 840 includes a POI (coupon) list 841, a LOC list 842, and an SNI list 843. The global list 840 includes an existing RTM list for traffic information and A PTI list or the like may be added, but the present invention will be discussed.

First, when a user calls a TTI service to view coupon information in a POI, a list of POIs (coupons) included in a global list is loaded (1002), and a basic list screen for the entire loaded list is output (1004). . That is, only the basic information of the loaded POI list is displayed on the screen.

Basic information corresponding to the name of the entire POI (coupon) list can be output to the screen (1004), and detailed information corresponding to the output basic information can be selected (1006). If not, wait for the next command.

When an item on the list is selected by the user and switched to the detailed information screen, it is searched whether POI (coupon) data of the detailed information on the selected item is received (1008). This can be done by version checking.

If there is no POI (coupon) data received by performing the version check, the display of the POI (coupon) information is terminated without outputting a detailed information screen.

If there is POI (coupon) data received by performing the version check, the corresponding data is fetched from the database list (1010) to determine whether the message IDs are the same (1012). That is, the ID of the selected component and the corresponding component ID of the stored database are checked. Here, determining whether the message IDs are the same is a part of determining whether the driver or the pedestrian is a list of the corresponding information.

If the message IDs of the data extracted from the list are not the same, it is repeated from the process of searching for the presence of POI (coupon) information. But you can also wait for the next command.

If the message IDs of the data extracted from the list are the same, detailed information of the data is output through a screen display and / or voice (1014). In addition, switching from the detailed information screen to the basic list screen or ending the POI (coupon) information viewing can be performed at any time by selecting a menu.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

As described above, the present invention provides a high value-added TTI service such as a coupon service for POI to an information user through a unidirectional digital broadcasting system or a bidirectional return channel, thereby maintaining perfect compatibility with application services defined in the existing TPEG protocol. It is possible to efficiently transmit high value-added data and to overcome the limitations of existing TTI services.

The present invention provides only one data field indicating whether the coupon service is available in the unidirectional POI stream, and provides the actual coupon data through the return channel. In this case, it is possible to efficiently transmit through a limited data channel and to provide a coupon service for a fee using a return channel.

The present invention provides, for example, a one-way service for transmitting coupon information provided by a business performing a POI event, a discount, or a preferential event to TPEG data, or providing only coupon service availability information through one-way and requesting a user. Depending on the return channel provides a coupon service, and the receiving terminal stores and manages the stored coupon images separately, visit the company and select the coupon from the list of stored coupons to display on the screen, discount and free services, etc. It can be easily provided, it is effective to be provided only to the paying user by using a premium coupon through the return channel.
