The present invention relates to a DMB / mobile communication integrated service terminal and a method for interworking a network between digital multimedia broadcasting (DMB) and mobile communication, and more particularly, a mobile communication terminal and a mobile DMB receiving terminal as one entity. DMB / mobile communication integrated service terminal for interworking network between DMB and mobile communication by integrating and physically and logically interworking to receive DMB broadcasting service in mobile environment and to receive bidirectional data service through mobile communication network. It's about how.

When data broadcasting technology is used in digital TV, which is attracting attention as the next generation TV (TV) technology, it is provided by existing personal computer (PC) such as World Wide Web (WWW) service and e-commerce. It can provide various services that can be done. However, since data broadcasting has a limitation due to broadcast characteristics that only one-way transmission is possible, a method of installing a modem or a network device in a digital TV has been proposed to overcome these limitations and enable two-way communication.

However, in the case of a modem, its practicality is limited due to the speed limitation. In the case of a high-speed network such as an asymmetric digital subscriber line (ADSL) or a local area network (LAN), the home TV is not used. Up to now, there is a problem that it may take a considerable time to become an environment capable of connecting network lines.

In addition, when setting up a network using a TV, there is a problem in that the network setting is very complicated and it is very difficult for the user to directly set up the network.

In order to solve the above problems, a method for allowing a user authentication through a user recognition unit present in the portable terminal, each of which has an interface unit for allowing the digital TV receiver and the portable terminal to communicate with each other has recently been proposed. It became.

It is provided through a bidirectional data broadcasting network.

PCS (Personal Communication System), which is a typical portable personal terminal 106, is provided with a PC connection in consideration of a connection with a personal computer (PC) or a notebook PC. Therefore, once the digital TV receiver 104 is provided with such a connection and enables an interface with the portable terminal 106, communication between the two devices 104 and 106 is possible.

When the user selects an item to be purchased, the code for the product is transmitted to the portable terminal 106 through a connection part included in the digital TV receiver 104, which in turn is connected to the mobile communication network 108 and the base station ( 110 is retransmitted to the broadcast station 100.

Then, the broadcasting station 100 detects user information and the like and connects it with the seller for the corresponding product, thereby finally delivering the product to the user (buyer).

In the bidirectional data broadcasting service using the portable terminal, since the portable terminal and the digital TV receiver exist as separate entities, interconnection is always required in use, and message and data processing between the broadcasting system and the communication system is performed independently. As a result, the data conversion process is required.

In addition, there is a problem in that the user has a problem in using two handsets (digital TV receivers, portable terminals) in order to always use the portable terminal or to receive the above two-way service in a mobile environment.

The DMB / mobile communication network interworking API consists of APIs for implementing the DMB / mobile communication network interworking platform 220 of FIG. 2 and should be added for interworking between the two systems and the basic API used in broadcasting and mobile communication terminals. It is composed of an extension API to be extended, and it should be scalable by reflecting the requirements of content providers, service providers, and terminal manufacturers.

Here, the basic API and the extension API are divided into a high level API and a low level API, respectively.

4 is a diagram illustrating an embodiment of a network interworking platform between the DMB and mobile communication of FIG. 2 according to the present invention.

The low level API 430 is a layer for supporting hardware independence in the porting of DMB / mobile communication network interworking platforms and applications. This creates an abstraction for the terminal and allows the platform to be configured independently of the hardware.

That is, API is used to easily port (porting) various terminal hardware companies DMB / mobile communication network interworking platform and application programs to the terminal-specific operating system. Here, the DMB terminal related API 431 is a low level API for porting to hardware related to DMB reception, and the mobile terminal related API 432 is a low level API for porting to hardware related to a mobile communication connection.

The platform engine (interlocking engine) 420 is a library that provides an environment in which the high-level APIs 410 can be executed. The high-level APIs 410 allow application developers to independently execute applications. It is an API that enables development and provides an environment in which various applications can be executed independently of terminal hardware and services. The higher level API 410 uses a DMB application related API 411, a mobile communication application related API 413, and a DMB broadcasting and mobile communication service simultaneously. DMB / mobile communication application related APIs 412 for executable applications.

The application / API manager 400 manages the download, addition, update, and deletion of applications and related APIs.

5 is a flowchart illustrating an embodiment of a DMB / mobile communication integrated service method in a DMB / mobile communication integrated service terminal according to the present invention.

APIs are called according to whether the application program is for DMB broadcasting, mobile communication, or a coordinated application. Therefore, when a user is requested to execute a specific application (501), first, the type of the specific application is checked (502).

As a result of checking the application type, if the called application is a DMB broadcasting-only application (for example, AV player, etc.), after calling a higher level API (DMB application related API) (503), the DMB terminal related child A DMB broadcast related service is performed with the level API call 504 (505).

As a result of checking the application type, if the called application is a mobile communication-only application, after calling a higher level API (mobile communication application related API) (510), the mobile terminal related low level API call (511). The mobile communication related service is then performed (512).

Next, a case where the called application program is a DMB / mobile communication interworking application program (for example, a data browser) will be described.

Basically, after DMB / mobile communication service receives broadcasting contents using DMB, user can watch AV or browse data, and if necessary, detailed data or personal data of broadcasting contents can be charged. You will be served using. Accordingly, when the DMB / mobile communication interworking application is executed, the API related to the DMB / mobile communication interworking application is called (506), and the low-level API related to the DMB terminal is called (507) and the DMB broadcasting related service is performed (508). . If there is a request from the user for the mobile communication network service while the DMB broadcasting related service is running (509), the low-level API related to the mobile communication terminal is called to perform the mobile communication related service (511, 512).

According to the service, unlike the above, the mobile communication service is first performed in the DMB / mobile communication interworking service, and the DMB broadcasting related service may be performed at the request of the user. That is, if the application type is checked and the application is a DMB / mobile communication interworking application, the API related to the DMB / mobile communication interworking application program is called, and the mobile communication terminal related low level API is called to perform the mobile communication related service. do. During the mobile communication related service, if the user requests, the DMB broadcasting related service is executed by calling the low level API related to the DMB terminal.

6 is a diagram illustrating an embodiment of a DMB / mobile communication integrated service terminal and a method for interworking a network between a DMB and a mobile communication according to the present invention.

The multimedia processor 212 decodes the demodulated and demultiplexed multimedia streams from the DMB broadcasting preprocessor 211 and separates them into video / audio and synchronization data (data required to be synchronized with audio / video). Through the AV player 631 through the screen and the speaker of the terminal, the synchronization data is output to the DMB / mobile communication network interworking platform 220.

The data processor 213 decodes asynchronous data (data that does not need to be synchronized with video / audio) output from the DMB broadcast preprocessor 211 and then transmits the mobile data transmitted from the return server through the mobile communication network connection 240. Combine to generate network interlocking data in the form of file data

The lower level API 430 is API functions that perform functions such as channel setup and change (601), data event generation (602), data read (603), mobile network connection (604), data request (605), and the like. It is composed.

Here, the channel setting and changing function obtains a request for service information (SI) of a higher level API function, tunes a broadcast frequency based on the service information (SI), and selects a subchannel of a specific service. The video / audio of the selected service is output to the screen and the speaker through the application 230 via the direct memory, but the decoded data file is read by the data read function of the low level API.

After the channel setting and change is completed, when a service is selected and broadcast data is received, the data event generation function generates an event that broadcast data has started to be received and notifies the upper level API, and reception of broadcast data is completed. When the data file is restored to a file format required by an application program such as a data browser 632, the upper level API is notified as an event that reception of broadcast data is completed.

The mobile communication network access function performs a function of connecting to a return channel server (mobile communication service server) through the mobile communication network, and the data request function is a data to a return channel server (mobile communication service server) existing in the mobile communication network. It forwards the request and receives response data (mobile data) to it to notify the high level API of the event.

The high-level API 410 includes a broadcast service control package 621, an AV control package 622, a locator package 623, a data file control package 624, a mobile communication network control package 625, and the like. It may be configured as.

The broadcast related service control package 621 may change a broadcast channel and a subchannel, and provide functions and interfaces related to a service such as a broadcast program guide, service change and search.

The AV control package 622 plays DMB audio / video and controls the playback position and the size of the audio / video.

The data file control package 624 provides a control function for the data file received through a broadcast or return channel. That is, the data file control package 624 is a package provided to process a data file transmitted through a mobile communication network or a DMB broadcast as interlocked in the DMB / mobile communication network interworking platform. By using this data file control package 624, an application (application) using a DMB / mobile communication network interworking platform can view the contents of the data file in the same manner regardless of the data file delivery path, and transfer the data file. You may be notified of the beginning and end of

Locator package 623 is a package that provides a logical method for specifying resources (services or files) in the DMB / mobile communication network interworking platform. The assignment of resources hides details and provides a package that enables you to specify resources consistently in other parts of the DMB / mobile interworking platform.

The mobile communication network control package 625 is configured as a package for providing various wireless Internet services after accessing the mobile communication network.

Generally, data file formation in a mobile communication terminal is made in a higher level API, but in the present invention, a data file (DMB / mobile communication network interworking data file) for interworking with a DMB / mobile communication network is generated by the data processor 213. The DMB / mobile communication network interworking data file thus generated is processed by the lower level API 430. This is because the data transmitted to the mobile communication network is transmitted through a TCP connection, so it is rarely segmented. However, since the data transmitted through DMB broadcasting is usually divided and transmitted repeatedly, the decoding and file combining process is performed at a lower level. This should be done to improve the efficiency of the system.

Therefore, the data file (DMB / mobile communication network interworking data file) for the DMB / mobile communication network interworking application is preferably processed at a lower level to form a linked file object, whether transmitted through DMB broadcast or mobile communication network. .

The data browser 632, which is an integrated browser, which is a kind of application 230, generates a control command by a user's operation, and uses a parameter information to be transmitted when a file reception completion event of a corresponding service occurs. The file is read and displayed on the screen along with the audio / video (AV) broadcast.
