More particularly, the present invention relates to a mobile broadcasting system and method using DMB, which can broadcast a broadcast information message associated with a predetermined DMB broadcast program to at least one DMB terminal by using a Cell Broadcasting Service (CBS) system and, when a callback request is received from a user of the DMB terminal, control a connection between the DMB terminal and a predetermined server associated with the DMB broadcast program, and thereby enables the user of the DMB terminal to directly participate in the DBM broadcast program.
Background Art
Digital Multimedia Broadcasting, which is DMB, is a broadcasting service which modulates various types of multimedia signals, such as a speech signal, an image signal, and the like, into a digital format, and provides the modulated multimedia signals to a portable terminal or a vehicle receiver. DMB is referred to as a 'television (TV) on a hand'. DBM is technologically based on Digital Audio Broadcasting (DAB) which is a digital radio technology. Here, a concept of multimedia broadcasting is added. For example, DMB is a service which can additionally transmit data information, such as moving pictures, weather, news, locations, and the like. Generally, DMB enables a user to receive a broadcasting service via a portable terminal. Accordingly, while moving, the user may readily utilize the broadcasting service in compact disc (CD) or digital versatile disc (DVD) quality via a portable terminal or a vehicle receiver without restrict to a time and a place. Due to the above- described reasons, DBM is in the spotlight as the next generation in broadcasting. Also, due to developments of various types of communication technologies, recent broadcast viewers desire to directly participate in a broadcast program, and also desire to acquire various types of information associated with the broadcast program which is on air. For example, when the viewers are currently viewing a quiz program, the viewers may desire to solve the quiz together with a panelist. Also, when the viewers are currently watching a soap opera, the viewers may desire to acquire information about clothes that a leading actress is wearing and also may desire to buy the clothes.
When digital broadcasting services are more actively distributed, the viewers' real-time participation is expected to be realized. However, the real-time participation is not realized in a DMB service which is a type of digital broadcasting. Also, many users receive a DMB service via a mobile communication terminal which has a DMB receiving module embedded, but in this case, the users utilizes a DMB service and a mobile communication service separately. Accordingly, a synergy effect according to integration of the DMB service and the mobile communication service may not be expected.
Accordingly, development of a two-way communication technology which can provide a DMB service by integrating a mobile communication function and a broadcast receiving function of a DMB terminal, and thereby, enable a DMB broadcasting viewer to participate in a broadcast in real time and instantly receive all types of information about a DMB broadcast program via a DMB terminal is required.

The broadcast information database 210 stores program information, a broadcast information message, broadcast time information, and cell information about at least one DMB broadcast program which is broadcasted via a predetermined DMB system. Here, the broadcast information message includes callback information which consists of a Uniform Resource Locator (URL) or a telephone number corresponding to an ARS server, a WAP server, or a Web server associated with the program information.
The program information, the broadcast information message, the broadcast time information, and the cell information, which are stored in the broadcast information database 210, may be provided from a server of the DMB system 272 or a broadcasting company which produced the program.
The program information, the broadcast information message, the broadcast time information, and the cell information stored in the broadcast information database 210 will be described in detail with reference to FIG. 3.
FIG. 3 is a diagram illustrating an example of a broadcast information database 300 which stores program information, a broadcast information message, a broadcast time information, and cell information according to an embodiment of the present invention.
As shown in FIG. 3, the broadcast information database 300 stores a broadcast information message, broadcast time information, and cell information corresponding to each of at least one DMB broadcast program information.
The program information includes various types of information, such as a program title, and the like. Here, the program title is used for identifying the DMB broadcast program which is provided to the DMB terminal 273 via the DMB system 272. Also, the broadcast information message includes a predetermined broadcast event and callback information corresponding to all of the program information. Here, the broadcast event may be generated by each DMB broadcast program producer. For example, as shown in FIG. 3, a broadcast event "find Nohongcheol in COEX, take a picture with him, and apply for an event" may be set as a broadcast event corresponding to program information "find a star".
Specifically, to encourage viewers to more actively participate in a broadcast program, a program producer may set a broadcast event of giving a free gift by lottery, when the viewers who view the DMB broadcast program entitled "find a star", finds a comedian, Nohongcheol, in COEX and takes a picture with him, and transmits the picture to a predetermined server. The set broadcast event is included in the broadcast information message, and stored in the broadcast information database 300.
The broadcast information message further includes callback information. When a DMB terminal user requests a callback for the broadcast event, the callback information may include a network address of a predetermined server that the DMB terminal can connect with, or a telephone number of the server, which enables the DMB terminal to connect with a voice-based system, such as ARS/Interactive Voice Response (IVR), and the like.
In the above-described example, when the DMB terminal user found Nohongcheol and took a picture with him in COEX, the DMB terminal user may transmit the picture to a predetermined server by requesting a callback for the broadcast information message. Here, the server may be a Web server of a broadcasting company which produced the DMB broadcast program "find a star" or a WAP server of a predetermined mobile communication provider which includes a site of the DMB broadcast program. Accordingly, in this case, the callback information may be embodied into a network address of the Web server or the WAP server, such as "204.8.3.12". The broadcast time information includes information about a time when the broadcast information message was broadcasted to at least one DMB terminal. Specifically, according to an embodiment of the present invention, when the broadcast information message associated with the DMB broadcast program is transmitted to the DMB terminal while broadcasting the DMB broadcast program, the program producer may encourage the viewers to more actively participate. Accordingly, it may be desirable that the broadcast time information is set in correspondence to an actual broadcast time of the broadcast program. However, the broadcast time information may include additional time information in addition to the broadcast time according to the program producer's intention. Also, the broadcast time information may be set by various types of methods .
The cell information includes information about a predetermined region where the broadcast information message is being broadcasted. The mobile broadcasting system 200 may broadcast the broadcast information message to at least one DMB terminal 273 via the CBS system 271. Specifically, the mobile broadcasting system 200 may not transmit the broadcast information message to the DMB terminal 273 corresponding to a particular mobile phone number, but broadcast the broadcast information to any DMB terminal 273 which is located in a predetermined cell via the CBS system 271. The predetermined cell may be variously set according to characteristics of the broadcast program corresponding to the cell information. In the above-described example of the program information "find a star", the broadcast event is set to take a picture with Nohongcheol in COEX. Accordingly, the region of COEX may be set as an area where the broadcast information message is broadcasted. In this case, the cell information may be set as "COEX 1 district, COEX 2 district, and COEX 3 district". The cell information may be set by various types of methods according to region information based on a current base station status of each mobile communication provider.
Referring again to FIG. 2, the information extraction unit 220 extracts a broadcast information message corresponding to a broadcast time from at least one broadcast time information, and cell information corresponding to the broadcast information message by referring to the broadcast information database 210.
Specifically, the information extraction unit 220 identifies broadcast time information identical to a current time by comparing the broadcast time information and the current time, and extracts the broadcast information message corresponding to the identified broadcasting information and the cell information from the broadcast information database 210.
When the broadcast time arrives, the information extraction unit 220 may extract the broadcast information message and the cell information. Also, the information extraction unit 220 may receive an extraction command signal of the broadcast information message and the cell information from a predetermined external server, or may extract the broadcast information message and the cell information according to a user's selection. The broadcast control unit 230 controls the CBS system 271 to broadcast the extracted broadcast information message to at least one DMB terminal, which is located in a region corresponding to the cell information, by transmitting the extracted broadcast information message to the CBS system 271. The broadcast control unit 230 transmits the broadcast information message and the cell information to the CBS system 271 via the first communication module 240.
The first communication module 240 communicates with the CBS system 271 and the DMB system 272 via the first network 261. In this case, the first communication module 240 may include a modem for connecting with the wired/wireless Internet. Also, the first communication module 240 may include various types of communication modules according to an embodiment method of the first network 261.
As an example, the first communication module 240 may include at least one of a local area network (LAN) access modem, a serial interface, a Universal Serial Bus (USB), an Infrared (IR) communication unit, a Bluetooth communication unit, and a mobile communication interface. The mobile communication interface may support a Public Switched Telephone Network (PSTN) connection method, and also support at least one of CDMA, WCDMA, All IP, GSM, GPRS, and all existing connection methods associated with the mobile communication. Also, the mobile communication interface may support at least one of H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP) and call control protocols for VoIP call connections, such as Megaco protocol, and the like. The second communication module 250 communicates with the CBS system
271, the DMB system 272, or the DMB terminal 273, via the second network 262. To communicate with the DMB terminal 273, the second communication module 250 may include a mobile communication module which can support at least one of CDMA, WCDMA, All IP, GSM, GPRS, and all existing connection methods associated with the mobile communication.
Also, the second communication module 250 may include at least one of an Internet access modem, a LAN access modem, a serial interface, a USB interface, an IR communication unit, and a Bluetooth communication unit, and may support at least one of H.323, MGCP, SIP, and call control protocols for VoIP call connection, such as Megaco, and the like.
The CBS system 271 receives the broadcast information message and the cell information from the mobile broadcasting system 200, and broadcasts the broadcast information message to at least one DMB terminal 273 which is located in the region corresponding to the cell information. The DMB terminal 273 receives the broadcast information message, and displays the broadcast information to the user. When a callback with respect to the broadcast information message is received from the user, the DMB terminal 273 attempts to connect with a predetermined server corresponding to callback information by referring to the callback information which is included in the broadcast information message.
For example, in the above-described example of the program information "find a star", when the user of the DMB terminal 273 takes a picture with Nohongcheol in COEX, and requests a callback, the DMB terminal 273 transmits the picture to a server corresponding to the callback information "204.8.3.12". After transmitting the picture, the user may check whether the user's picture won the event while viewing the DMB broadcast program "find a star".
Also, in the above-described example, when the DMB broadcast program continues in a form of an event with respect to a predetermined region, the mobile broadcasting system 200 using DMB according to the present invention may be effectively utilized. Specifically, it is possible to enable a DMB viewer to participate in a broadcast program in real time and enjoy himself/herself with a program host by providing a plurality of unspecific DBM viewers with an event of a broadcast program in real time and also receiving a callback corresponding to the broadcast program from the viewer in real time.
Also, the mobile broadcasting system 200 using DMB according to the present invention may be effectively applied to a broadcast "find a lost child". Referring to FIG. 3, when a current broadcast program corresponds to a find-a-lost-child program entitled "lost children", the mobile broadcasting system 200 may broadcast the broadcast information message "please give information about a child on air" corresponding to the broadcast program, to a plurality of DMB terminals 273 via the CBS system 271. The cell information corresponding to the broadcast information message may be set in correspondence to a region where the child was lost. For example, when the region where the child was lost is Seohyundong of Bundanggu, the cell information may be set as "Seohyun 4 district and Seohyun 5 district."
At least one DMB terminal user who is located in Seohyundong of Bundanggu receives the broadcast information message from the mobile broadcasting system 200 via the CBS system 271. When the user sees a child who looks similar to the lost child, the user may give information about the child by requesting a callback with respect to the broadcast information message. In this case, the callback information included in the broadcast information message may be a telephone number of Police Agency for Missing Children.
Also, the callback information may be a server of Police Agency for Missing Children or a server of a broadcasting company. Accordingly, when the DMB terminal user sees a child who is suspected as the lost child, the DMB terminal user may take a picture of the child and transmit the picture to the server via a callback request. In this case, parents of the lost child or a program manager may verify whether the child is the one that they are looking for from the picture. Accordingly, the lost child may be more accurately and effectively found than using a conventional method. As described above, according to the mobile broadcasting system 200 of the present invention, the DMB terminal user may easily participate in a DMB broadcast program which the DMB terminal user is currently viewing via a DMB terminal. Also, the DMB terminal user may check a participation outcome during the DMB broadcast program on air. Accordingly, it is possible to encourage viewers to more actively participate in the DMB broadcast program.
According to another embodiment of the present invention, the mobile broadcasting system 200 may receive a callback signal from the DMB terminal 273, store the callback connection information of the DMB terminal 273 in a database, and control a connection between a predetermined server corresponding to the callback signal and the DMB terminal 273.
In this case, the mobile broadcasting system 200 may further include the callback information database 280 and the callback connection information unit 290.
The callback information database 280 may store subscriber information about at least one DMB terminal user, and callback connection information corresponding to the subscriber information. The subscriber information and the callback connection information stored in the callback information database 280 will be described in detail with reference to FIG. 4.
FIG. 4 is a diagram illustrating an example of a callback information database 400 which stores subscriber information and callback connection information according to another embodiment of the present invention.
The callback information database 400 may store subscriber information about at least one DMB terminal user. Here, the subscriber information designates information about the DMB terminal user who subscribed to a mobile broadcasting service using DMB according to an embodiment of the present invention. Also, the subscriber information may include a subscriber name and the subscriber's DMB terminal phone number.
The callback information database 400 may store callback connection information corresponding to the subscriber information. Here, the callback connection information designates callback information that the DMB terminal user, which received the broadcast information message from the mobile broadcasting system
200, requests in correspondence to the broadcast information message. The callback connection information may include the callback information, which is included in the broadcast information message, and may include a callback time when the DMB terminal user requested the callback.
Also, in addition to the callback information and the callback time as shown in FIG. 4, the callback connection information may include a total number of callback requests, a callback request probability with respect to the received broadcast information message, and the like, and in this state, be stored in the callback information database 400.
As described above, the mobile broadcasting system 200 may output callback connection statistics of the DMB terminal user by receiving a callback signal from the DMB terminal which broadcasted the broadcast information message, storing the callback connection information, and controlling the connection between the server and the DMB terminal. Also, the outputted callback connection statistics may be utilized for useful marketing information of an operator of the mobile broadcasting system 200 or a broadcast program producer.
FIG. 5 is a flowchart illustrating a method of providing a mobile broadcasting service using DMB according to an embodiment of the present invention.
According to the present embodiment, in operation 511 , a DMB terminal user views a DMB broadcast program via a DMB terminal.
