Details of the above object and technical configuration of the present invention and the resulting effects thereof will be more clearly understood from the following detailed description based on the accompanying drawings.

First, FIG. 1 is a diagram illustrating a network for explaining a GUIP service system of the present invention, and FIG. 2 is a diagram illustrating a GUIP server according to an embodiment of the present invention.

As shown in FIG. 1, the GUIP service system of the present invention is a GUIP server 210 which is accessible by a DMB terminal 100 that receives and plays DMB broadcast content from a broadcasting center 30 through a bidirectional data service path of a mobile communication network. And a content server 220.

The DMB terminal 100 is a terminal for receiving satellite DMB broadcasting contents through a satellite from the broadcasting center 30 or terrestrial DMB broadcasting contents through a terrestrial transmission station, and is a base station / base station controller that is a data service path of a mobile communication network ( A terminal connectable to the GUIP server 210 and the content server 220 via the BTS / BSC 10 and the packet data service node PDSN 20.

The GUIP server 210 provides information on the type of additional information that can be provided for each object displayed on the digital multimedia broadcasting screen. Hereinafter, the information provided by the GUIP server 210 is referred to as PPL information.

That is, the GUIP server 210 enables the user to select a specific object on the broadcast screen and interoperates with the DMB terminal 100 receiving the PPL information, so that the user can receive additional information content on the selected object. As a supporting server, for example, when the user presses any GUIP start key while watching a broadcast, the contours of the objects (eg, a singer, a singer's costume, etc.) appearing on the broadcast screen after that point in time can be provided for each object. Information about the type of information (for example, the profile of the singer, the record of the singer, the lyrics of the song the singer sings, the information of the costume of the singer, etc.), and the information, that is, the download address (URL) of the content is transmitted.

Meanwhile, the contour information is information for selecting a object by the user. When the contour information is synchronized with the broadcast screen, the DMB terminal 100 can display the contour of the object selected according to the user's key input. It is provided as guide information that allows the user to select a specific object.

If the DMB terminal having a touch screen does not need to provide guide information separately for object selection, in this case, the DMB terminal transmits the coordinate information of the point selected by the user to the GUIP server 210 and the object at the selected point. You can get directly information about.

Therefore, in such a case, the GUIP server 210 does not have to provide all PPL information for subsequent broadcasts in advance, and information on the type of additional information that can be provided to the object of the corresponding point and content URL information ( Hereinafter referred to as GUIP information).

As described above, when the DMB terminal 100 selects an object (a person, a product, etc.) appearing on the broadcast screen while watching the broadcast, the GUIP server 210 can check information that can be provided for the selected object. It provides a URL to download the content for the content from the content server 220, the configuration for this is shown in FIG.

As shown in FIG. 2, the GUIP server 210 of the present invention includes a GUIP service control unit 211, a PPL information retrieval unit 213, a PPL information download unit 215, and a GUIP information provider 216. It is configured by.

The GUIP service control unit 211 receives a GUIP start request message including channel information and program information of a broadcast currently being viewed from the DMB terminal 100 and starts GUIP including information included in the received GUIP start request message. The response message is transmitted to the DMB terminal 100 so that information can be confirmed by the user or the terminal.

The GUIP start request message is a service request message that is automatically generated and transmitted from the DMB terminal 100 as the user selects the GUIP start key from the DMB terminal 100. The GUIP start request message includes: MTS number, PTS information provided to know the current broadcast time; GUIP service type information, terminal type information (laptop, mobile phone, etc.), broadcast channel information, broadcast program information may be included.

PTS (Presentation Time Stamp) is a time stamp included in a DMB broadcast data packet. PTS of the packet header enables the user to find a screen when a user requests a service in a corresponding broadcast program. 210 provides PPL information or GUIP information for the time or after the time.

The GUIP service type information is information for distinguishing a download method, and in the present invention, the GUIP server 210 downloads the PPL information in a full download mode and a partial download method. And ONDEMAND.

Here, the full download method and the split download method may download PPL information including contour information, types of additional information, and content URLs of a plurality of objects for subsequent broadcasts of the corresponding broadcast program when the PPL information request message is received. In this case, the total download method downloads the PPL information for the entire broadcast program at once, and the split download method divides the PPL information into an appropriate size to distribute the network traffic load at regular intervals and sequentially. Say the way.

The on-demand method is a method applied to the DMB terminal 100 having a touch screen. When a specific point is received and a GUIP information request message including coordinates is received, only the type of the additional information and the content URL of the corresponding object are received. This method downloads GUIP information.

Such a GUIP service type may be preset in the DMB terminal 100, may be selected when the GUIP start key is pressed, or may be stored in the subscriber database 212 of the GUIP server 210.

On the other hand, if the GUIP service proposed in the present invention is provided only to the service subscriber, the GUIP service control unit 211 checks whether the subscriber's information is present in the subscriber database 212 when receiving the GUIP start request message, and performs subscriber authentication. After executing, you can reply to the GUIP start response message with the authentication result.

Next, when the PPL information retrieval unit 213 receives a PPL information request message including channel information and program information of a broadcast from the DMB terminal 100, the PPL information search unit 213 receives the PPL information based on the information included in the PPL information request message. The PPL information about the broadcast program is retrieved from the database 214 and URL information for downloading the PPL information is provided to the DMB terminal 100.

In this case, since the PPL information search unit 213 should search for PPL information on the corresponding broadcast after the DMB terminal 100 requests PPL information, the PPL information search unit 213 may request a PPL information request message received from the DMB terminal 100. The PPL information for the part to be watched later is searched using the PTS information indicating the playing time of the included broadcast program.

The PPL information database 214 includes guide information for selecting an object displayed on a broadcast screen, a kind of additional information that can be provided for each object, and a content URL information for downloading each additional information content. Information is stored for each broadcast program.

For example, in the case of a music broadcast program, an object of the PPL information may be a singer displayed on the screen. Examples of additional information that may be provided for the singer include profile information of the singer, record information of the singer, and the current information. There may be a song being played. If the user selects a song, the user may provide the corresponding sound source content as additional information content. In this case, the download URL information of the sound source content is included in the PPL information.

The guide information is information for allowing a user to select one of the objects displayed on the broadcast screen. As described above, the guide information may be outline information for displaying the outline of the object, and may be variously designed in addition to the outline. . In addition, the guide information is synchronized with the broadcast data in the DMB terminal 100 so that the user can display the guide information such as the outline of the corresponding object according to the key input so that the user can select the desired object through the key input while watching the broadcast.

If the PPL information download unit 215 provides URL information for downloading the PPL information retrieved to the DMB terminal 100 by the PPL information retrieval unit 213, the DMB terminal 100 accesses the URL. Download the corresponding PPL information.

As mentioned above, since the PPL information download method includes a full download method and a split download method, the PPL information download unit 215 may include a full download method that is a download method of the PPL information in a PPL information request message, and a split download method. When the information on any one of the download methods is included, or when the corresponding information is stored in the subscriber database 212, in the case of the full download method according to the information, the entire PPL information is downloaded at once, and the split download method In this case, the PPL information to be downloaded is divided into a proper size, and each split PPL information is sequentially downloaded.

Next, the GUIP information providing unit 216 is a configuration for a service to the DMB terminal 100 having a touch screen, and the channel information of the broadcast currently being viewed from the DMB terminal 100 as the user selects a specific point of the broadcast screen. When a GUIP information request message including program information, coordinate information of a selected point, and PTS information is received, the user selects a reference to the PPL information database 214 based on the information included in the GUIP information request message. The GUIP information response message including the type of additional information that can be provided for the branch and the content URL information for downloading each additional information content is transmitted to the DMB terminal 100.

In this case, the PPL information database 214 should further store the coordinate information of the object displayed on the broadcast screen, and exactly the information on the range of coordinates for the screen area occupied by the object.

Meanwhile, in the case of the PPL information downloader 215, the PPL information for the broadcast after the user requests a service is given down, and the corresponding PPL information includes guide information for selecting an object. After downloading the PPL information, the user can identify the object selected by the user and receive the corresponding additional information content.

On the other hand, the GUIP information providing unit 216 receives the coordinate information selected by the user in real time, identifies the object corresponding to the coordinates and gives only relevant information.

Meanwhile, in FIG. 2, when the PMB information is downloaded to identify the object in the DMB terminal 100, and when the coordinates are transmitted in the DMB terminal 100, the GUIP server 210 identifies the object and provides only the GUIP information. Although the GUIP server 210 is configured to perform both cases, the GUIP information providing unit 216 may be omitted if only the former service is provided, and the PPL information retrieval unit 213 if only the latter service is provided. And the configuration of the PPL information downloader 215 may be omitted.

Referring to FIG. 3 and FIG. 4, a detailed interworking method and service process of the GUIP server 210 and the DMB terminal 100 described with reference to FIGS. 1 and 2 will be described below.

First, FIG. 3 is a flowchart sequentially illustrating a GUIP service method according to an embodiment of the present invention, and shows a process in the case of downloading PPL information.

As shown, the DMB terminal 100 receives the DMB content broadcasted from the broadcasting center 30 (S301) so that the user can watch the DMB content (S303), and the user can view the GUID during the viewing of the DMB content. When the start key is selected (S305), the GUIP server 210 transmits a GUIP start request message (S307). In this case, the GUIP start request message must include channel information, broadcast program information, PTS information, and the like, and basically includes the MIN number of the terminal and the type of the terminal.

The GUIP server 210 includes the information included in the received GUIP start request message for the terminal or subscriber confirmation and transmits the GUIP start response message to the DMB terminal 100 (S309). In this case, the function of the GUIP start request message and the function of the GUIP start response message may be included in a subsequent PPL information request message and a PPL information response message.

The DMB terminal 100 again transmits a PPL information request message including a channel, a program, and PTS information to the GUIP server 210 (S311). Accordingly, the GUIP server 210 based on the corresponding channel, program, and PTS information. In step S313, the corresponding user searches for PPL information about the broadcast being viewed and includes URL information for downloading the PPL information in the PPL information response message.

Upon receiving the PPL information response message, the terminal 100 automatically receives a user confirmation and accesses the corresponding URL to download the PPL information (S315). In this case, the PPL information includes object selection guide information such as contour information and information for each object. Information on the type of additional information that can be provided and URL information of each additional information content are included.

On the other hand, although the PPL information download process (S315) is represented as one in the figure, in the case of the split download method, the divided PPL information may be downloaded several times at regular intervals.

The DMB terminal 100 having downloaded the PPL information as described above synchronizes the PPL information with the DMB broadcast data to support the user's object selection and additional information selection, and when the user selects the outline of a specific object while watching the broadcast (S317). The type of additional information about the corresponding object is displayed (S319), and when any one of them is selected (S321), the user accesses the additional information content URL to download the content requested by the user (S323).

Next, FIG. 4 is a diagram for an embodiment of receiving GUIP information by transmitting coordinate information of an object.

As shown, the DMB terminal 100 receives the DMB content broadcast from the broadcasting center 30 (S401) and plays the corresponding broadcast content for the user to watch (S403), and when the user selects the GUIP start key. (S405) Automatically accesses the GUIP server 210 and transmits a GUIP start request message (S407). At this time, information such as a channel, a program, a PTS, a terminal MIN, and a terminal type is automatically inserted into the GUIP start request message.

At this time, if a GUIP start response message is received from the GUIP server 210 (S409), the DMB terminal 100 activates a function for allowing a user to select an object on the broadcast screen.

In general, even if a user presses a specific point on the screen on the touch screen, the user may not perform any operation or may perform a predetermined function among DMB broadcasting functions, so that the DMB terminal 100 may provide a service of the present invention. When the GUIP start key is selected, when the user selects a specific point on the screen after activating the corresponding service function (S411), the GUIP information request message including corresponding coordinate information (horizontal axis, vertical axis) and PTS information is sent to the GUIP server ( 210) (S413).

At this time, the GUIP information request message must include channel, program information, and the like. In some cases, the GUIP information request message may be implemented such that the information is not transmitted again, as the information is transmitted through the GUIP start request message.

The GUIP server 210 identifies an object corresponding to the coordinates selected by the user on the screen and the broadcast screen that the user watched at that time, based on the coordinate information included in the GUIP information request message, the PTS information, and the PPL for the GUIP server 210. Search for information (S415).

In this embodiment, since only the type and content URL of the additional information that can be provided for the object selected by the user among the PPL information to be searched need to be provided, the GUIP server 210 does not provide a URL for separately downloading the corresponding information. The GUIP information (message type and content URL) is included in the GUIP information response message and returned (S417).

Accordingly, the DMB terminal 100 displays information on the type of additional information among the received GUIP information on the screen (S419). When the user selects specific additional information (S421), the DMB terminal 100 accesses the corresponding content URL and downloads the content. (S423).

As those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features, the embodiments described above should be understood as illustrative and not restrictive in all aspects. Should be. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
