The present invention is derived from the research conducted as part of the IT growth engine technology development project of the Ministry of Information and Communication and the Ministry of Information and Telecommunications Research and Development. .

In general, a digital broadcasting system and a terminal transmit and receive a service according to a locator format similar to a URI format and suitable for a corresponding broadcasting environment. The locator information describes various digital broadcasting services and elements constituting the above-described services, and can access the corresponding services and components according to a user's request. For example, DVB defines DVB locators in the DVB SI and MHP specifications, and CableLabs defines OCAP locators in the OCAP specifications.

Currently, the terrestrial DMB environment is a TTA standard 'Digital Multimedia Broadcasting (DMB) mobile application terminal environment; The terrestrial DMB (TTAS.KO-07.0047, MATE) 'defines the MATE locator, and the DAB environment defines a separate DAB locator specification.

DAB locators specify existing DAB services and service components, and MATE locators also specify terrestrial DMB services in other formats.

Meanwhile, in order to access a service using a bidirectional communication network from a terminal device receiving a terrestrial DMB service, the existing Internet environment is a separate standard for text messaging and telephone connection with a defined URL standard (Digital Multimedia Broadcasting (DMB) bidirectional service). TTAS.KO-07.0053).

However, since the existing locator standard cannot be used as a locator standard necessary for interworking between services constituting the terrestrial DMB, and there is no national standard that specifies a program unit of the current terrestrial DMB service, the current terrestrial DMB service is not available in a specific time zone. You cannot represent program events that are broadcast on.

Therefore, there is a problem that there is no interworking technology between the services constituting the terrestrial DMB.

The present invention has been made to improve the prior art as described above, the user consuming a terrestrial DMB service can facilitate switching to a variety of services associated with the service, and can provide a variety of DMB services to the user An object of the present invention is to provide a DMB service interworking method and a DMB service interworking system.

Referring to FIG. 1, the DMB service interworking system 100 includes a locator extracting unit 101, a locator receiving unit 102, a location information generating unit 103, a link program searching unit 104, and a request performing unit 105. It includes.

When the DMB service interworking system 100 receives a program identifier (eg, CRID) from the DMB server, the locator extracting means 101 performs a function of analyzing the program identifier (CRID) to extract the locator.

The locator receiving unit 102 performs a function of receiving a locator from the DMB server. The above-described locator can accurately distinguish only a part of the program indicated by the locator including time information. The time information may include a start time and a running time of the program.

The location information generating means 103 analyzes the received locator and generates the location information of the link program associated with the locator. That is, the position information generating means 103 can generate the position information of the link program from the locator described above.

The link program search means 104 performs a function of searching for a link program using the generated location information when a service request for the link program of the DMB user occurs. That is, when the DMB user makes a request related to the program being serviced, the link program search means 104 may search for the location of the link program stored in the specific server through the location information of the generated link program.

The request performing means 105 performs a function of performing a service request for the found link program. That is, the request performing means 105 may perform a service such as 'reserved recording' for the link program requested by the DMB user, with respect to the searched link program.

On the other hand, when receiving the DMB program programming information (EPG) from the DMB server, the locator extracting means 101 analyzes the DMB program programming information to extract the programming identifier (eg ContentsID), and the location information generating means 103 extracted The location identifier of the link program may be generated by analyzing the organization identifier.

Hereinafter, an embodiment of the DMB service interworking system of the present invention will be described with reference to FIGS.

The composition of the DMB service interworking system consists of providing the terrestrial DMB link program location information and the service interworking using the same.

First, the DMB service interworking system utilizes the existing locator standard for terrestrial DMB service location information. The locator specification describes the location of the link program associated with the locator utilizing at least one of a DAB locator, a Mate locator or a BWS locator.

Next, the locator may include time information. Existing locators contain time information, which can limit the specific time zone of the link program associated with the DMB program in service, so that it can accurately point to all or part of the link program.

 When the DMB service interworking system receives the CRID instead of the locator, the locator extracting means extracts the locator from the received CRID using the TV-Anytime function. That is, since the CRID does not specify the type of locator, the locator extracting means extracts a specific type of locator from the received CRID. For reference, the CRID format is 'CRID: // <authority> / <data>', and the DMB service interworking system may acquire location information of the link program in the CRID format through separate Contents Resolution Information.

Finally, when the DMB service interworking system receives an EPG, which is DMB program organization information, the DMB service interworking system may extract ContentID from the above-described EPG and generate location information of the link program from the extracted ContentID.

The DMB service interworking system adds a terrestrial DMB locator associated with the link program, assuming that there is another link program associated with the corresponding program in one terrestrial DMB service. The DMB service interworking system analyzes the terrestrial DMB locator according to a user's service request or a request of a program in service. The DMB service interworking system first analyzes the locator protocol method (MATE locator, BWS locator, DAB locator) and analyzes the given locator according to the appropriate locator specification.

If the requested service is a switch from DAB audio to DMB video service, the DMB service interworking system may attempt to switch to the corresponding service, and if the requested service is reserved recording, reserved viewing, or reserved download, The service request for the link program may be performed according to the included time information.
