The present invention relates to a method for processing a telephone number using a digital multimedia broadcasting standard. In particular, a digital multimedia broadcasting (DMB) transmits video data and a telephone number for an interactive service. The phone number is extracted and displayed so that the user can easily call the relevant place (eg home shopping order reception center) while watching the video broadcast.

The Digital Multimedia Broadcasting (DMB) standard is a standard for mobile reception of multimedia. The European Digital Audio Broadcasting (DAB) standard, which is the basis of this standard, is designed to digitize existing analog radio broadcasts while simultaneously transmitting and receiving various types of broadcasts. Looking at the main types of broadcasting, it is divided into audio broadcasting and other data broadcasting.

The DMB standard enables video broadcasting by transmitting MPEG-4 data to a data broadcasting standard within the DAB standard. In addition, since the DMB standard can transmit other types of data in addition to MPEG-4 data, the DMB standard can support multimedia broadcasting capable of mobile reception. Because of this, it is possible to derive not only the DMB receiver itself but also many applications using the same. An example is a combination of a cell phone and a DMB receiver.

On the other hand, due to the nature of digital multimedia broadcasting, various services may be provided in which a user makes a call to a specific place in relation to broadcasting.

As an example, a user watching a home shopping broadcast may wish to immediately purchase a product or service currently being sold on the broadcast. In this case, a user using a conventional home shopping service had to dial an order using a general telephone or a mobile phone after seeing the order number displayed on the broadcast screen. In other words, broadcasting and ordering are separated into completely different procedures, which may cause inconvenience to the user, and there is a problem of obstacles to increase in sales for the home shopping service provider.

Accordingly, the present invention has been proposed to solve the above problems, and in the case of digital multimedia broadcasting (DMB), the video data and the telephone number for the interactive service are transmitted together, and the receiving side plays the video while playing the video. The purpose of the present invention is to provide a method for extracting the number and displaying the number automatically so that the user can easily call the place related to the broadcast while watching a video broadcast (for example, a home shopping order reception center).

In order to achieve the above object, the telephone number processing method using the digital multimedia broadcasting standard according to the present invention, the telephone number corresponding to a certain video service component on the MSC (Main Service Channel) of the DMB transmission frame (DMB Transmission Frame) Carrying the data as stream data, and displaying and indicating the telephone number on the fast information channel (FIC); Receiving a DMB transmission frame, the DMB receiving apparatus decoding the FIC of the DMB transmission frame and the stream data and the video service component carried in the MSC; Checking, by the DMB receiving apparatus, stream data belonging to the same service as the video service component by analyzing MCI (Multiplex Configuration Information) information of the FIC; And the DMB receiving apparatus reproduces the video service component, and extracts the telephone number from the stream data belonging to the same service as the played video service component when the FIC is marked indicating that the telephone number is loaded. It comprises the step of displaying on the display screen.

Indicating that the telephone number is included, TMId is' 01 'among the corresponding service component description items belonging to the service field of "Extension 2 of FIG type 0", and DSCTy is' 111110' or '111111. Set to 'to classify the type of data service. Among the service component description items in the DSCTy Extension field of “Extension 7 of FIG type 0”, TMId is' 01' and Ext DSCTy is the phone number. Is an arbitrary 10-bit code indicating that the subcarrier is loaded, SubChId may be set to the subchannel number carrying the telephone number.

The DMB receiving apparatus may be preferably configured as a mobile communication terminal capable of receiving digital multimedia broadcasting. When the mobile communication terminal is a mobile phone, the user can easily place an order call to a relevant place (eg, a home shopping order reception center) while watching a digital multimedia broadcast on a mobile phone.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring briefly to the DMB standard with reference to Figure 1, the DMB transmission frame (DMB Transmission Frame, 10) is composed of a Synchronizaton Channel (11), Fast Information Channel (FIC, 12), Main Service Channel (MSC, 13).

In the structure of the DMB transmission frame, the synchronization channel 11 is a channel for transmitting information for decoding on a digital communication, and the MSC 13 is a channel through which data to be actually broadcast is transmitted. That is, video, audio, and various types of broadcast data are transmitted through the MSC 13 during digital multimedia broadcasting. In the MSC 13, data must be transmitted without error. Are sent together. The FIC 12 transmits information necessary to determine which channel in the MSC 13 is transmitted through the actual broadcast data. In this channel, error correction data other than the CRC is not transmitted because it is intended for fast information transfer.

Referring to Figure 2, the process of the telephone number processing in the digital multimedia broadcasting according to the present invention will be described.

First, the DMB transmission device 15 loads a phone number corresponding to a certain video service component as stream data in the MSC 13 of the DMB transmission frame 10, and the phone number is loaded in the FIC 12. Display and transmit (S21).

On the other hand, the DMB receiver 16 receiving the DMB transmission frame 10 transmitted by the DMB transmission apparatus 15 is the stream data and the video service component loaded on the FIC 12 and the MSC 13 of the DMB transmission frame. Decode all of them (S22).

In addition, the DMB receiver 16 analyzes MCI (Multiplex Configuration Information) information of the FIC 12 to identify stream data belonging to the same service as the video service component (S23). That is, the MCI (not shown) of the FIC 12 includes information for identifying which video service component and stream data belong to the same service (for example, one home shopping broadcast program).

In addition, the DMB receiver 16 reproduces the decoded video through the display screen as in the function of a general DMB receiver (S24).

At this time, the DMB receiver 16 extracts the telephone number from the stream data belonging to the same service as the video service component to be played and displays it on the display screen when the FIC 12 is marked to indicate that the telephone number is loaded. (S25 to S27).

Through the process described above, the DMB receiving apparatus 16 to which the present invention is applied can display a phone number associated with the currently broadcast digital multimedia broadcasting. To this end, a promise is made between the DMB transmitter 15 and the DMB receiver 16 to indicate that a telephone number is carried and how the actual telephone number will be loaded. It is desirable that such commitments be made without changing the DMB protocol.

One preferred embodiment for indicating that a telephone number is carried is defined as a type of data service in the FIC 12 as to apply the present invention, and subchannel information of stream data including numbers or special characters and the subchannel information. It defines a field to display information that defines that the numbers or special characters of the channel represent phone numbers. Then, the DMB receiving apparatus 16 can recognize that the service is a telephone number display service according to the present invention through the type of data service, and after extracting the numbers or special characters in the corresponding subchannel, If the phone number is indicated, these numbers or special characters can be displayed on the display screen as a phone number.

FIG 0/2 (Extension 2 of FIG type 0) defines a 'basic service organization', and all service descriptions applied to each service have one field (eg, service k, 31).

The service fields Service k and 31 again include various fields, among which each service component description included in the service field 31 is included. The service component description (eg, 32) is divided into a 2-bit TMId (Transport Mechanism Identifier) 33 and another 14-bit region 34. When the TMId 33 is '01', a type of data service is identified. DSCTy (Data Service Component Type, 35) used for this purpose is included.

As shown in Fig. 4, the contents of the DSCTy 35 are designated. If the DSCTy is '111110' or '111111', there is no content currently specified in the DSCTy. This means that you can specify any DSCTy and perform any table in 'Ext DSCTy', an extended DSCTy included in another FIG Type. Therefore, by setting DSCTy to '111110' or '111111', the type of data service to which the present invention is applied can be distinguished.

Referring to FIG. 5, an embodiment in which a subchannel carrying a number or a special character and a phone number indicating the number or the special character included in the subchannel through the Ext DSCTy field will be described.

Ext DSCTy (Extended Data Service Component Type) belongs to FIG 0/7 (Extension 7 of FIG type 0) of the FIC 12 and provides additional information about a service component type not included in the DSCTy table. to provide. The DSCTy Extension field (eg, 51) includes a TMId field 52 and various other fields, among which a service component description 53 corresponding to the DSCTy Extension field 51 is included.

If the TMId is '01', the service component description 53 has a 6-bit SubChId field 55 and a 10-bit Ext DSCTy field 54. That is, when TMId 52 is '01', subchannel information carrying numbers or special characters is loaded in the SubChId field 55, and the information indicating that the number or special characters is a telephone number is displayed in the Ext DSCTy field 54. You can set At this time, the Ext DSCTy field may be defined as an arbitrary value.

In summary, the DMB receiver 16 can find a subchannel to be a service component using the SubChId field 55, and extracts numeric or special character data from the subchannel located in the MSC 13. Then, it is determined that the number or the special character means the telephone number by using Ext DSCTy information.

On the other hand, the role of the DMB receiving device 16 that operates as described above may be preferably performed by a mobile communication terminal having a built-in DMB receiving function. A mobile phone is an example of such a mobile communication terminal.

Referring to FIG. 6, a phone number related to a broadcast currently being viewed is output on a display screen of a mobile phone 60 outputting a digital multimedia broadcast, and a user presses a schedule button such as a call button or displays a current display screen. The phone number can be dialed through a user interface (UI) menu that allows a user to select and display a phone number displayed or displayed in the past.

Referring to FIG. 7, an example of a process to which the present invention is applied when watching a home shopping broadcast using a mobile phone having a DMB reception function will be described.

The DMB transmission device 15 transmits a home shopping broadcast containing a telephone number for ordering an item currently being broadcast, and the user watches the home shopping broadcast using the mobile phone 70. Then, the mobile phone 70 extracts the order phone number and displays it on the display screen, and the user can easily make an order call by pressing a call button or attempting to call this phone number on a schedule menu.
