The present invention relates to a recording medium for a point information / news information service frame structure and a TPEG-based application service processing apparatus using the same. More particularly, the present invention relates to a transport and travel (TTI) service transmission through a digital broadcasting system. Define a frame structure that can provide high value-added application services such as point of interest (POI) and news information based on the TPEG (Transport Protocol Experts Group) protocol. The present invention relates to a recording medium for a point information / news information service frame structure capable of providing a value-added application service, and a TPEG-based application service processing apparatus using the same.

In general, digital broadcasting (digital television broadcasting, digital satellite broadcasting, digital audio broadcasting, etc.) systems provide or provide multimedia data broadcasting services such as traffic and travel information (TTI), electronic program guides (EPGs), and game content. Is on schedule. Among these, the TTI service sector is notable in terms of economic ripple effects and information utilization in the future. The reason for this is the increase in the number of automobiles and the increase in demand for traffic and travel information due to the five-day workweek.

The TPEG 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 standard to date are RTM (Road Traffic Message) and PTI (Public Transport Information), and currently, parking information, congestion and travel time information (PKI) within the TPEG Forum Standardization of new services such as Congestion and Travel Time Information (CTI), Weather (WEA) and Environment Information Alerts (EIA) is underway.

However, the introduction of high value-added TTI services through the review of new service standards for the provision of point of information and news information, which are very important information during driving and travel, or through the extension of existing application service standards, has not been considered until now. to be.

Traffic and travel (TTI) information can be transmitted by various transmission media such as FM radio broadcasting, Internet, mobile communication, etc., but the information transmitted is selected by standardized system to secure time constraints and accuracy. And must be edited. Therefore, the basic system of TTI (traffic and traveler information) delivery can be divided into information sorting, editing and conveying work.

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 as shown in FIG. 2.

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 containing B / TPEG members, and since 1999, has developed two standards (Part 3 and Part 1) to support services. 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.

 TPEG enables the addition of new functions and modification of protocols without interfering with the operation of previous receivers or decoders, especially for efficient one-to-many transmission of information through broadcast systems. It can be widely used for the required application. It is also suitable for one-to-one or multicast applications and is designed to be easily included in Internet protocols.

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

Currently, the TPEG Forum is currently standardizing new services such as parking lot information (PKI), congestion and travel time information (CTI), weather information (WEA) and environmental pollution warning (EIA), as described above. In other words, the TTI (Traffic and Travel Information) application service defined in TPEG is limited to traffic information such as RTM and PTI.

Therefore, in order to overcome the limitations of existing TPEG-based TTI services, new TTI service-related information (for example, high value-added application services such as branch information (POI) and news information) while maintaining compatibility with application services defined in TPEG. There is an urgent need for a new TTI service scheme that can effectively service data over a limited data rate broadcast channel.

7 is a configuration diagram of an embodiment of an TPEG-based application service processing apparatus according to the present invention.

As shown in FIG. 7, the TPEG-based application service processing apparatus according to the present invention is an application service processing apparatus based on a TPEG (Transport Protocol Experts Group), and based on a point information (POI) -related TPEG protocol through a broadcasting communication network A broadcast stream receiving module 10 for receiving a broadcast stream (that is, a POI broadcast stream or a news information broadcast stream or a POI + news information broadcast stream), and analyzes the received broadcast stream to discard an error frame and discard the error. A parser 20 for extracting a missing frame and delivering it to the decoder 30, and a decoder 30 for identifying POI / news information-related data by identifying service component characteristics of the frame extracted by the analyzer 20. ) And the POI / news information related data classified by the service component in the decoder 30, and the POI / news information related database (in the case of POI, point information (POI) list 41). Location information (LOC) list 43, system configuration information (SNI) list 44, and news information (NWS) list 42, system configuration information (SNI) list 44), respectively. , According to the global list 40 for managing and the POI / news information service request from the user, the corresponding POI / news information related database of the global list 40 is searched, and the retrieved POI / news information related data is outputted. A control unit 50 for controlling, and an output unit 60 for outputting the POI / news information related data under the control of the control unit 50.

The broadcast stream may be received with point information (POI) and / or news information independently or mixed, and in a frame structure for point information (POI) transmission, a TPEG-LOC component indicating POI-related location information behind an event container must be used. Although accompanying (see FIGS. 3 to 6 above), unlike the RTM, PTI, POI services, the frame structure for transmitting news information does not include the TPEG-LOC component due to the nature of the news, the geographical classification is defined in "Classification" It is classified by item classification.

Then, look at the configuration and operation of each component in more detail as follows.

First, the broadcast stream receiving module 10 receives a TPEG-based broadcast stream including point information (POI), news information, and traffic information through a broadcast communication network, and includes a parser 20 and a decoder ( The TPEG broadcast stream received in 30) is analyzed and loaded into a list (POI list, NWS list, LOC list, SNI list) in different databases according to the characteristics of the service component.

Here, the functions of the analyzer 20 and the decoder 30 will be described in more detail. The parser 20 discards an error frame in a frame of the TPEG broadcast stream, extracts an error-free frame, and extracts a decoder ( The decoder 30 decodes each frame information (service component property) in order to load the frames into different database lists (POI list, NWS list, LOC list, and SNI list). ) Is used to identify frames by checking message IDs.

Subsequently, the data (particularly, branch information (POI) and news information) classified for each service component characteristic through the analyzer 20 and the decoder 30 are listed in different databases according to the service component characteristic (POI list, NWS list). , LOC list, SNI list).

For example, the type of database includes a point information (POI) list 41, a news information (NWS) list 42, a location information (LOC: Location) list 43, and a system configuration information (SNI). There is a list 44 and the data is stored in list form in each database. 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.

Here, looking at each database in more detail, the point information (POI) list 41 is a database that stores gas stations, restaurants, lodging, cultural information, tourism information, etc., the news information list 42 is related to the news A database that stores information (characters of news, actual news information, time information related to news, information about the author, etc.). The LOC list 43 is a database that stores corresponding location information for driving in conjunction with the point information (POI) data or the news information data, and the SNI list 44 is a point information (POI) / news information transmission protocol. It stores information about frame structure and service structure.

The overall list including the point information (POI) list 41, the news information list 42, the LOC list 43, and the SNI list 44 stored in the form of a list in each database is called a global list 40. do.

Therefore, according to the present invention, in the receiver (navigation system) in the global list 40 including the point information (POI) list 41, news information list 42, LOC list 43 and SNI list 44 A driver using a receiver (navigation system) by extracting data (point information (POI), news information, etc.) of a list that matches the characteristics of the data (point information (POI), news information, etc.) requested by the driver or pedestrian. Where a pedestrian is located, the service may be provided, and a process of processing unnecessary data may be omitted, and a prompt and accurate point information (POI), news information, and the like may be provided (screen output and / or audio output).

Hereinafter, the POI and news information service processing methods included in the TPEG broadcast stream will be described in detail.

8 is a flowchart illustrating a process of processing point information (POI) and news information streams in a TPEG-based application service processing apparatus according to the present invention, in which TPEG broadcast stream reception is continued until the end time with the start of a receiver (navigation); The message ID and version are checked and loaded into each component list.

First, before explaining the process of processing the point information (POI) and news information stream, the TPEG broadcast stream is described. In the TPEG broadcast stream, data such as point information (POI), news information, and traffic information are continuously propagated. The TPEG broadcast stream is a useful information that can be stored while the receiver (navigation system) is operating, but is impossible to store when the receiver (navigation system) is terminated. It's just a flow of data. 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 an operation of a receiver (navigation system) is started by a user (801), it initializes a variable for the module 10 that receives a broadcast stream and performs a command to start receiving the broadcast stream. 10) is activated (802). At this time, the broadcast stream receiving module 10 is controlled by the controller 50.

Thereafter, the receiver executes a reception thread for the operation of the broadcast stream receiving module 10 (803), and the receiving thread analyzes the TPEG broadcast stream (804) to add the received frame to the list. Specifically, the process of adding the received frames to the list is described in detail. If each frame is decoded and point information (POI) data according to the frame message ID (806), it is stored in the POI list 41 (807). If it is news information data (808), it is stored in the NWS list 42 (809). If it is LOC data (810), it is stored in the LOC list 43 (811), and if it is SNI data (812), it is stored in the SNI list 44 (813).

At this time, data that is not included in any characteristic data among point information (POI) data, news information data, LOC data, and SNI data is not added to the global list 40.

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 (814), the reception thread ends the reception of the broadcast stream ( 815, the receiver (navigation) ends (816).

FIG. 9 is a flowchart illustrating a process of calling point information (POI) and news information in a TPEG-based application service processing apparatus according to the present invention, and shows whether there is desired point information (POI) and news information data among received broadcast streams. By calling the list of loaded components (41 ~ 44) can provide the point information (POI) and news information required by the user.

As described above, a list including a point information (POI) list 41, a news information (NWS) list 42, a LOC list 43, and an SNI list 44 is stored in the global list 40. Although the RTM list and the PTI list for the traffic information may be added here, the traffic information service will be discussed in the present invention.

First, when a user calls a TTI service to view point information (POI) and news information and selects point information (POI) or news information from the TPEG service configuration menu as shown in FIG. 10 (901), the global list 40 The POI list 41 or the NWS list 42 included in is loaded (902).

Thereafter, a basic list screen for the entire loaded list is output (903). That is, only the basic information of the loaded point information (POI) list 41 or news information (NWS) list 42 is output as a list on the screen. In other words, basic information corresponding to the title of the entire message is displayed on the screen.

In this case, if there is no user selection and the screen is not switched to the detailed information output screen, the next command is waited for (910).

If an item on the list is selected by the user and the screen is switched to the detailed information screen (904), it is searched whether point information (POI) or news information (NWS) data of the detailed information on the selected item is received. In 905, the searching process can be performed by version checking.

If there is no point information (POI) or news information data received by performing the version check (905), the view of the point information (POI) / news information is terminated without performing a detailed information screen output (909).

If there is the received point information (POI) or news information (NWS) data by performing the version check (905), the corresponding data is taken from the database list (906) and it is determined whether the message IDs are the same (907). That is, it checks whether the ID of the selected component matches the corresponding component ID of the stored DB. Here, determining whether the message IDs are the same is a part of determining whether the driver or the pedestrian is a list of corresponding information.

If the message IDs of the data extracted from the list are not the same (907), the process repeats from step 905 of searching for the presence of the point information (POI) or news information (NWS) data. However, it may process to wait for the next command (910).

If the message IDs of the data extracted from the list are the same (907), the detailed information (point information POI or news information) of the data is displayed on the screen and / or sound output (908).

In addition, switching from the detailed information screen to the basic list screen or ending viewing of the point information (POI) / news information (NWS) 909 may be performed at any time by selecting a menu.

10 is a diagram illustrating a configuration screen of a TPEG service in a receiver (navigation) according to the present invention.

In FIG. 10, the TPEG 101 is a main menu used to view data such as traffic information, point information (POI), and news information (NWS) received through a broadcasting communication network. Five menus are classified as submenus.

Traffic information 102 is a service that provides traffic accidents or road conditions information, public transportation 103 is a service that provides information about trains, buses and ships, point information (POI) 104 is a restaurant or hospital It is a service for providing facility information, such as news information (NWS) 105 is a service that provides the main news, the environment setting 106 is a menu used when performing the environment setting of the TPEG service.

When the POI service 104 is selected from the submenus of the TPEG 101, the process and the screen configuration of the service are shown in FIG. 11.

That is, when the POI menu is selected on the TPEG service configuration screen of FIG. 10, related POI components are listed as shown in FIG. 11, and when the detailed information of the restaurant “Seoul spaghetti” is selected, a restaurant is selected. Information about menus and parking lots is displayed on the screen with images. At this time, the audio output of the information may be parallel.

In addition, according to the classification system of POIs, components such as hospitals, restaurants, and accommodations can be filtered according to the needs of consumers, and the location of the selected POIs is also shown.

Meanwhile, when the news information (NWS) service 105 is selected among the sub-menus of the TPEG 101, a process and an example of the screen configuration of the service are shown in FIG.

That is, when the News Information (NWS) menu is selected on the TPEG service configuration screen of FIG. 10, related news information components are listed as shown in FIG. 12, and among them, the detailed information of the news, "Seoul extreme cold" Then, the article about the news, information about the author, etc. are displayed on the screen with the image. At this time, the audio output of the information may be parallel.

In addition, according to the defined classification system of news information, components can be filtered according to the needs of consumers by region, usage, and climate.
