A computer-readable recording medium recording a disaster information providing apparatus, a method of providing a disaster information, and a program for realizing the same. }

The present invention relates to a disaster information providing apparatus using a TPEG, a disaster information providing method and a computer-readable recording medium recording a program for realizing the same. More specifically, the present invention relates to a TPEG message using link information in a disaster alert service message. By referencing, it is possible to provide disaster information in a multimedia format, and link information generated dynamically according to the range of disaster information providing area and the number of senders providing TPEG service can be used to provide efficient disaster information. A disaster information providing apparatus using a TPEG, a disaster information providing method, and a computer-readable recording medium having recorded thereon a program for realizing the same.

The present invention is derived from a study conducted as part of the Seoul-Industrial-Academic Cooperation Project (2005 Technology Foundation Project) of Seoul Metropolitan Government. [Task Management No.:10561, Title: Intelligent Urban Information Convergence System for Smart (Ubiquitous) City Development].

The Disaster Alert Service (AEAS) receives the Automatic Emergency Alert Service Message from the broadcast signal according to the transmission protocol of digital broadcasting, and expresses the received Disaster Alert Service message according to the transmission protocol. It is configured to be.

The apparatus for receiving a disaster alert service includes not only a general digital broadcast receiver but also a dedicated terminal for receiving a disaster alert service message.

In addition, digital broadcasting may include broadcasting services such as terrestrial digital broadcasting, cable or satellite digital broadcasting, IP-TV broadcasting using a communication network, terrestrial digital multimedia broadcasting (T-DMB), or satellite digital multimedia broadcasting. Can be.

In particular, the case of performing a disaster alert service using terrestrial digital multimedia broadcasting (T-DMB) will be described in more detail.

Domestic T-DMB standard defines ensemble, service, service component to express service model. "Ensemble" is a basic unit that is modulated by RF and transmitted. One ensemble may include several services. "Service" means a unit that a receiver can select and watch. A service may consist of one or more "service components". One service component transmits on one transport channel.

A service component refers to an element constituting a service in terms of a service model, and a transport channel refers to a set of transport protocols used to transmit a service component in terms of a protocol.

1 is a diagram illustrating a protocol stack of a conventional T-DMB.

As shown, T-DMB transport channels are largely divided into FIC (Fast Information Channel) and MSC (Main Service Channel).

FIC transmits multiplex configuration information (MCI) for signaling of T-DMB services, and FIC provides high level of transmission error protection without time interleaving to receive MCI quickly and securely. Apply.

In general, since the capacity allocated to the FIC is limited, the MCI is transmitted first, and then the system information (SI) is transmitted using the FIC.

The Fast Information Data Channel (FIDC) may be used for paging, TMC (Traffic Message Channel) or EWS (Emergency Warning Systems) transmission within the FIC. FIDC is a transmission channel for specialized receivers or simple mobile receivers that offer relatively low data rates but where power consumption can be an important issue.

MSC is composed of Audio Stream Mode, Network Level Packet Mode, and Data Stream Mode, and in each mode, Transparent Data Channel (TDC) and Data Linked (DLS). The service component is transmitted using a service, IP tunneling, multimedia object transfer (MOT), MPEG4 data, and the like.

In the T-DMB service model, an ensemble is a "multiplex operator" and a service is a "service provider". The T-DMB receiver selects one service provided by the service provider, decodes and provides a service component constituting the service to the receiver. In other words, from the service point of view, the general receiver can only know information about the service provider.

When performing a disaster alert service based on the T-DMB, the service model may be classified into a case where a disaster alert service is provided by a service provider and a case where a disaster alert service is provided by a multiplex provider.

The disaster alert service message is generated by the disaster prevention agency or the local government's disaster management organization, etc., and the subject of such a disaster alert service message is hereinafter referred to as "disaster alert service message issuing agency".

2 is a diagram illustrating a protocol stack and a disaster alert service message frame of a conventional T-DMB.

Referring to FIG. 2, the protocol stack of the T-DMB for a disaster alert service includes an AEAS message layer, an AEAS segmentation layer, a FIDC layer, an FIC layer, and a Transmission Frame Multiplexer (TFM) layer.

The FIC consists of up to 32 bytes and includes a FIG header, D1 / D2 / TCId / Ext, AEAS segment header, AEAS segment data, and CRC.

The FIG is composed of a maximum of 30 bytes and includes a FIG header, D1 / D2 / TCId / Ext, an AEAS segment header, and AEAS segment data.

AEAS segmentation includes AEAS segment header and AEAS segment data.

Disaster alert service messages can be used to send short and optional multimedia information to service viewers. In the case of short text, the size of the short text is transmitted to the FIDC, and the transmission of a large amount of multimedia information is defined to use the MSC. In order to express the connection between the disaster alert service message and the multimedia information related thereto, the disaster alert service message short message is defined to include a link of the multimedia information related to the disaster.

The format of the AEAS message, that is, the disaster alert service message is shown in FIG. 3.

3 is a diagram illustrating a format of a disaster alert service message according to the prior art.

Referring to FIG. 3, the disaster alert service message is an AEAS message, i.e., the disaster broadcast message is a 3 byte disaster type, a 2 bit alarm priority, a 28 bit disaster occurrence time, a 3 bit disaster area format, a 4 bit disaster Area number, 3 bit Rev, variable size disaster area, and variable size short text.

The short message included in the disaster alert service message indicates additional information such as text information and link information.

The format of the link information follows, for example, the format specified in "Terrestrial Digital Multimedia Broadcasting (DMB) Disaster Alarm Broadcasting" designated as 2007 TTAS.KO-07.0046 / R1.

Meanwhile, the TPEG (Transport Protocol Experts Group) is a protocol for transmitting traffic information and travel information to a terminal through a digital broadcasting medium. TPEG includes various transmission technology standards including encoding, decoding, filtering, etc., and TPEG services include real-time traffic information (CTT), notice information (RTM), summary image traffic information (CTT-SUM), and location of interest information ( Point of Interest (POI), Safe Operation Service (SDI), and News Information (NWS)

TPEG is a service that has recently been in the spotlight as it can provide multimedia traffic information to personal terminals through digital broadcast signals, and is expected to contribute to the expansion of the DMB market by providing real-time traffic information through DMB broadcasting.

4 is a diagram illustrating a TPEG service model according to the prior art.

Referring to FIG. 4, the TPEG service model includes three operators.

The content originator 100 collects data in various ways and processes the collected data to produce content. In addition, the content creator 100 classifies information in one application into meaningful groups to produce various contents.

For example, the content creator 100 may define traffic information of the nation represented by “congestion traffic information application” by dividing it into content composed of metropolitan area information and content composed of Busan / Gyeongnam area information.

The content creator 100 has a unique service identifier (OSID). Each content may be distinguished by a unique content identifier (COID) assigned by the content creator 100.

The combination of three identifiers of an OSID assigned to the content creator 100 and an application identifier (AID and COID) to which the content belongs is defined as an application content identifier (ACID).

ACID is used to reference content as a unique identifier worldwide.

The carrier 120 processes a task required to transmit the content provided by the content creator 100. The sender 120 finally creates a service frame.

The service frame is composed of a service component frame. The service component is a virtual transmission channel for transmitting each content provided by the content creator 100. That is, the sender 120 reserves one large channel for transmitting the TPEG stream, which can be considered to consist of a small channel called a service component.

The sender 120 carries one piece of content received from the content creator 100 to one service component. Every sender 120 has a unique Carrier Service Identification (CSID). In addition, service components are identified by a unique service component identifier (SCID) assigned by the sender 120. Therefore, the combination of CSID + SCID on the sender 120 side corresponds to the ACID on the content creator 100 side.

This relationship is described in TPEG-SNI's Guide to the Service Table 1: Fast Tuning.

The service frame created by one transmitter 120 is finally transmitted to the TPEG stream via a transport frame. In this case, the TPEG stream may be multiplexed into transmission frames prepared by various transmitters 120.

The role of the sender 120 may include such service multiplexing.

FIG. 5 is a diagram illustrating an example of various frames that a sender must perform to deliver a POI application message in the TPEG service model according to the prior art.

Referring to FIG. 5, the transmitter 120 creates various frames such as a service component frame, a service frame, a TPEG transmission frame, and the like. Each frame and the frame configuration can be referred to the prior art, so detailed description thereof will be omitted.

The transmission medium 130 transmits the transmission frame received from the transmitter 120 to the TPEG decoder (not shown) using a transparent transmission channel (eg, DMB, DVB, Internet, etc.). The transparent transport channel is, for example, a transport channel that outputs a sequence of input streams, and is a channel such as DMB, DVB, or the Internet.

6 is a diagram illustrating an example in which TPEG data is transmitted through various transmission media in the TPEG service model according to the related art.

Referring to FIG. 6, byte-shaped data generated by the TPEG generator 140 is transmitted to the TPEG decoder 160 in the form of bytes through the transmission channel 150.

The TPEG decoder 160 outputs TPEG data in the form of text, graphics, navigation data, speech data, for example.

7 shows a TPEG protocol according to the prior art.

The content producer 100 is responsible for the application layer of FIG. 7, the transporter 120 is responsible for the packet layer and the network layer, and the transport medium 130 is responsible for the data link layer and the physical layer.

Meanwhile, the service component (or content) is composed of TPEG messages except for TPEG-SNI (Service and Network Information). One TPEG message consists of message management, application, and location containers. Each TPEG message has a unique reference number, that is, a Message Identifier (MID) and carries a version number (VER) in each TPEG message. The message identifier and version number are essential elements included in all TPEG messages, which are used for the message management purpose of the TPEG decoder rather than the display purpose of the terminal.

As mentioned above, TPEG is used to display traffic-related information, and AEAS is used to inform imminent disasters.

TPEG is able to concretely indicate the disasters related to traffic or traffic conditions that can be caused by disasters other than traffic, and can provide detailed location information using various location expression methods. .

Therefore, if TPEG and AEAS are used at the same time, more effective disaster response is possible, but currently, the linkage between TPEG and AEAS is not considered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a disaster information providing apparatus using a TPEG of the present invention, a disaster information providing method and an embodiment of a computer-readable recording medium recording a program for realizing the same will be described in more detail with reference to the accompanying drawings.

8 is an exemplary block diagram of an apparatus for providing disaster information using a TPEG according to the present invention.

Disaster information providing apparatus using a TPEG according to the present invention described with reference to FIG. 8 may be implemented in a receiver for receiving and providing AEAS and TPEG.

Referring to FIG. 8, the disaster information providing apparatus 200 using the TPEG according to the present invention includes a disaster alert service message receiving unit 210, a link information extracting unit 230, and a TPEG disaster information providing unit 250. Include.

The disaster alert service message receiving unit 210 receives a disaster alert service message. For example, it corresponds to a configuration for receiving a disaster alert service message at a conventional AEAS receiver.

The link information extractor 230 extracts link information from the disaster alert service message received by the disaster alert service message receiver 210.

The TPEG disaster information provider 250 receives and provides TPEG data corresponding to the link information.

As described above, a method of referring to TPEG information in AEAS is not defined. In the present invention, the link information is defined and configured to refer to the TPEG information.

The link information is inserted in the disaster alert service message at the side sending the disaster alert service message or at the side generating the disaster alert service message.

The link information should preferably be expressed in a text manner and preferably have a Uniform Resource Identifier (URI) format.

As described above, the link information is recorded in the short field in the disaster alert service message, and the link information extracting unit 230 checks the short field and extracts the link information.

The link information can be recorded as follows.

First, link information using the above-described ACID.

For example, when the area for providing disaster information using the TPEG is more than a predetermined area range, that is, when the area for providing the disaster information is wide or the sender of the TPEG message is too large, the message sender cannot be specified.

In this case, the link information may include an originator service identifier (OSID), an application identifier (AID), a content identifier (COID), and a message identifier (MID) of the TPEG service. .

That is, the link information is generated using the ACID.

Link information using the ACID may be expressed, for example, in a Uniform Resource Locator (URL) format as follows.

"TPEGO: // OSID / AID / COID / MID"

The TPEG disaster information provider 250 extracts a sender corresponding to the link information extracted by the link information extractor 230 with reference to TPEG-SNI (Service and Network Information), and receives TPEG data transmitted from the extracted sender. Then, the received TPEG data is decoded and provided.

In particular, when using the link information using the ACID, the TPEG disaster information provider 250 first searches for a sender from the currently ensemble tuned. If the sender is not found in the ensemble currently being tuned, the TPEG disaster information provider 250 may search for and extract the sender from another ensemble.

It is also link information using the aforementioned CSID and SCID.

On the other hand, for example, when a region to provide disaster information using TPEG is within a predetermined region range, that is, when a region to provide disaster information is narrow or a sender of a TPEG message is specified, for example, a TPEG message sender is known in advance. .

In this case, the link information may include a carrier service identifier (CSID), a service component identifier (SCID), and a message identifier (MID) of the TPEG service.

Meanwhile, the link information may optionally include an extended country code (ECC) and an ensemble identifier (EID) of a digital audio broadcast ensemble.

That is, the link information is generated using the CSID and the SCID.

 The link information using the CSID and the SCID may be expressed in a URL format, for example, as follows.

"([dab.ensemble: // <ECC> <EId>],

TPEGC: // CSID / SCID / MID) "

The part "([dab.ensemble: // <ECC> <EId>]" may be optionally inserted.

The TPEG disaster information provider 250 extracts a sender corresponding to the link information extracted by the link information extractor 230, receives TPEG data transmitted from the extracted sender, and references the received TPEG data to the TPEG-SNI. To decode and provide.

That is, unlike the link information using the ACID described above, the TPEG disaster information provider 250 may extract the sender without referring to the TPEG-SNI. However, in order to decode the message, it is necessary to determine which application, and for this purpose, the TPEG disaster information provider 250 must refer to the sender's TPEG-SNI.

If the "([dab.ensemble: // <ECC> <EId>]" section is omitted, the TPEG disaster information provider 250 may extract the sender from the ensemble currently being tuned.

However, if the "([dab.ensemble: // <ECC> <EId>]") section is specified in the ensemble that is currently being tuned, the TPEG disaster information provider 250 may determine that the ensemble identified by the ECC and EID You can extract the sender.

In case of using link information using CSID and SCID, TPEG data can be received more quickly than link information using ACID.

9 is an exemplary flowchart of a disaster information providing method using TPEG according to the present invention.

The disaster information providing method using the TPEG according to the present invention described with reference to FIG. 9 may be performed by a receiver that receives and provides AEAS and TPEG. The receiver is for example a DMB receiver.

9, the receiver first receives a disaster alert service message (S110).

Since the reception of the disaster alert service message is the same as in the conventional AEAS receiver, detailed description is omitted.

Next, the receiver extracts link information from the disaster alert service message received in step S110 (S130).

The link information is inserted in the disaster alert service message at the side sending the disaster alert service message or at the side generating the disaster alert service message.

The link information should preferably be expressed in a textual manner, preferably with a URI format.

As described above, the link information is recorded in the short field in the disaster alert service message, and in step S130, the short field is checked to extract the link information.

Next, the receiver receives and provides TPEG data corresponding to the link information extracted in step S130 (S150).

Link information may take the following form:

First, link information using the above-described ACID.

For example, when the area for providing disaster information using the TPEG is more than a predetermined area range, that is, when the area for providing the disaster information is wide or the sender of the TPEG message is too large, the message sender cannot be specified.

In this case, the link information may include an originator service identifier (OSID), an application identifier (AID), a content identifier (COID), and a message identifier (MID) of the TPEG service. .

That is, the link information is generated using the ACID.

Link information using the ACID may be expressed, for example, in a Uniform Resource Locator (URL) format as follows.

"TPEGO: // OSID / AID / COID / MID"

In step S150, the sender corresponding to the link information extracted in step S130 is first extracted with reference to the TPEG-SNI, the TPEG data transmitted from the extracted sender is received, and the received TPEG data is decoded and provided.

In particular, in step S150, when link information using an ACID is used, the sender is first searched for in the currently ensemble tuned. If the sender is not found in the ensemble currently being tuned, in step S150, the sender may be searched for and extracted from another ensemble.

It is also link information using the aforementioned CSID and SCID.

On the other hand, for example, when a region to provide disaster information using TPEG is within a predetermined region range, that is, when a region to provide disaster information is narrow or a sender of a TPEG message is specified, for example, a TPEG message sender is known in advance. .

In this case, the link information may include a carrier service identifier (CSID), a service component identifier (SCID), and a message identifier (MID) of the TPEG service.

Meanwhile, the link information may optionally include an extended country code (ECC) and an ensemble identifier (EID) of a digital audio broadcast ensemble.

That is, the link information is generated using the CSID and the SCID.

 The link information using the CSID and the SCID may be expressed in a URL format, for example, as follows.

"([dab.ensemble: // <ECC> <EId>],

TPEGC: // CSID / SCID / MID) "

The part "([dab.ensemble: // <ECC> <EId>]" may be optionally inserted.

In step S150, the transmitter corresponding to the link information extracted in step S130 is extracted, TPEG data transmitted from the extracted transmitter is received, and the received TPEG data is decoded with reference to the TPEG-SNI.

In other words, unlike the link information using the ACID described above, the sender can be extracted in step S150 without referring to the TPEG-SNI. However, in order to decode the message, it is necessary to determine what application it is, and to do this, the sender's TPEG-SNI must be referred to at step S150.

If the "([dab.ensemble: // <ECC> <EId>]" part is omitted, in step S150, the sender can be extracted from the ensemble currently tuned.

However, if the "([dab.ensemble: // <ECC> <EId>]") part is specified in the ensemble currently being tuned, in step S150, the sender can be extracted from the ensemble identified by the ECC and the EID. .

In case of using link information using CSID and SCID, TPEG data can be received more quickly than link information using ACID.

10 is another exemplary block diagram of an apparatus for providing disaster information using a TPEG according to the present invention.

The disaster information providing apparatus using the TPEG according to the present invention described with reference to FIG. 10 may be implemented in a computing device on the side of generating a disaster alert service message or a computing device on the side of transmitting a disaster alert service message.

Referring to FIG. 10, the disaster information providing apparatus 300 using the TPEG according to another embodiment of the present invention includes a link information insertion unit 310.

The link information inserting unit 310 inserts link information on the TPEG disaster information into the disaster alert service message.

Link information for TPEG disaster information is dynamically generated based on the information of the region or sender that will provide the TPEG disaster information.

For example, when the region to provide TPEG disaster information is more than a predetermined region range, or when the sender for transmitting the TPEG disaster information is not specified, the link information inserter 310 may generate a creator service identifier (OSID) and an application identifier of the TPEG service. Link information including the AID, the content identifier COID, and the message identifier MID may be generated and inserted into the disaster alert service message.

Or, if the region to provide the TPEG disaster information is within a predetermined region range, or if the sender for transmitting the TPEG disaster information is specified, the link information inserter 310 is a sender service identifier (CSID) of the TPEG service, the service component Link information including an identifier (SCID) and a message identifier (MID) may be generated and inserted into the disaster alert service message.

By dynamically generating link information in this manner and inserting the link information into the disaster alert service message, the TPEG disaster information can be efficiently transmitted based on the region range to which the TPEG disaster information is transmitted and the sender.

The present invention also provides a computer-readable recording medium having recorded thereon a program for realizing each step of the above-described disaster information providing method using the TPEG according to the present invention.

A computer readable recording medium refers to any kind of recording device that stores data, that is, data in code or program form, so that it can be read by a computer system. Such computer-readable recording media include, for example, memories such as ROM and RAM, storage media such as CD-ROM and DVD-ROM, magnetic storage media such as magnetic tape and floppy disk, optical data storage devices, and the like. It also includes a case where it is implemented in the form of transmission via. Such computer readable recording media can also be distributed over network coupled computer systems so that the computer readable data is stored and executed in a distributed fashion.

However, a detailed description of such a computer-readable recording medium will be omitted since it overlaps with the disaster information providing apparatus using the TPEG and the disaster information providing method using the TPEG according to the present invention described with reference to FIGS. 8 to 9. .

Although the configuration of the present invention has been described in detail, these are merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. This will be possible.
