1 illustrates a content providing system using a DMB data channel according to an exemplary embodiment of the present invention. The content providing system is largely composed of a program provider side server, a content provider side server, a DMB broadcasting center, an antenna, a DMB receiving terminal, and a content subscriber DB server. In the present specification, the 'content' is a broad concept including all types of data provided to the user as an additional service such as a ringtone, coloring, music video, and text document. In addition, detailed description of parts irrelevant to describing specific contents of the present invention with respect to the DMB system will be omitted.

The program provider server is a server that generates a broadcast program and provides it to the DMB broadcasting center. All servers that provide a broadcast program, such as a conventional terrestrial broadcasting station or a cable TV broadcasting station, to the DMB broadcasting center correspond to this.

The content provider server is a server that generates content information used by a user through a wired / wireless communication network and provides the same to a DMB broadcasting center, and includes a content provider that provides content to a user through a conventional wired / wireless communication network. When the content provided with the broadcast is content related to the content of a broadcast program, more effective content download is possible. For example, if an educational broadcast program is provided with broadcast program related contents such as lecture summary notes in which a broadcast program content is described, it can be expected to download more related contents.

The broadcast center digitizes, compresses, and multiplexes the broadcast information received from the program provider server and the content information received from the server of the content provider to generate a broadcast information stream, and then transmits the broadcast information stream to the repeater. That is, the broadcast center periodically transmits content information using a broadcast data channel during broadcast.

 The repeater converts the broadcasting information stream received from the broadcasting center and transmits it to the DMB terminal through an audio channel, a video channel, and a data channel, and includes a DMB satellite, a ground antenna, or a gap filer. .

The DMB terminal includes all terminals having a receiver function for demodulating a CDM signal received from a repeater such as a mobile communication terminal, a PDA, a notebook computer, and outputting broadcast information to a subscriber. The DMB terminal includes content download authentication software using a data channel, while the DMB terminal receives a broadcast signal from the repeater.

The content subscriber DB server stores and manages the content download service subscription using the personal information and data channel of the DMB terminal user receiving the DMB broadcast. The user's name, address, social security number, mobile communication number, virtual account number, interests, etc. are stored as the user's personal information stored in the content subscriber DB server. Information related to the download service is stored together. In addition, when the DMB terminal user downloads the content while broadcasting, the content subscriber DB server authenticates the subscriber of the content download service so that the content is downloaded only to the DMB terminal of the authenticated user.

2 is a flowchart illustrating a process of downloading contents through a mobile communication network by driving authentication software embedded in a DMB terminal according to an exemplary embodiment of the present invention.

When the user receiving the DMB broadcast selects the download of the DMB data channel in the DMB terminal (S10), the authentication software built into the DMB terminal is driven (S20). The authentication software controls the DMB terminal to access the subscriber DB server through the mobile communication network and transmit a user authentication request signal to the subscriber DB server.

When the subscriber DB server receives the authentication request from the DMB terminal, the subscriber DB server extracts the content download service subscriber information stored in the subscriber DB server, performs authentication (S30), and transmits the authentication result to the DMB terminal.

If it is determined that the user of the DMB terminal has subscribed to the additional service, the DMB terminal starts to download the content data (S40). The terminal separates the content data from the received broadcast information stream and stores the content data in the memory unit of the terminal.

Then, the authentication software determines whether the download of the requested content data is normally completed (S50). If it is determined that the download is not completed normally, the process returns to step S40 again to restart the download of the content. If it is determined that the download is normally completed, the completion message is displayed on the display unit of the DMB terminal (S60), and the download process of the content data is terminated.

On the other hand, if the DMB terminal user does not subscribe to the supplementary service, or the authentication service by the subscriber DB server is found to expire or the usage period of the supplementary service expires, the terminal does not have the download authority. Do you want to subscribe monthly subscription? The content download service subscription guide message is displayed on the display unit of the DMB terminal.

When the guide message is displayed on the display unit, the input window is activated for a predetermined time in order to receive a monthly subscription from the user. When a download command is input within a predetermined time from the user, the DMB terminal accesses the subscriber DB server and requests to modify the monthly data channel download service information.

The subscriber DB server receives the monthly data download service information modification request, modifies the data download service subscription status to 'subscription', and transmits the modified data download service information to the DMB terminal.

The DMB terminal stores the received correction data download service information in the authentication information of the authentication software, and starts downloading the requested content data.

The process after the content download is the same as that of steps S to S, and the detailed description thereof will be omitted.

Meanwhile, as another embodiment of the present invention, the authentication information stored in the DMB terminal and the subscriber DB server may be configured to be synchronized. That is, for example, when a new data download service is subscribed to, an existing data download service is renewed, or a modification related to the data download service of the subscriber DB server occurs, such as the expiration of the data download service usage period, the subscriber DB server Sends the modification to the DMB terminal. Accordingly, since the authentication information of the authentication software stored in the DMB terminal stores new customer authentication information in association with the DB server, the user does not have to access the subscriber DB server every time the user downloads the data.

3 is a flowchart illustrating a sequence of downloading a lecture summary note during DMB broadcasting according to an embodiment of the present invention.

First, when a user views a DMB broadcast, content data is received in the form of a broadcast information stream along with the DMB broadcast data on the DMB terminal. When a data download command is input from the user, the authentication software in the DMB terminal is driven to start the user's data download service subscription authentication.

The authentication software requests the content download authentication by connecting the DMB terminal to the content subscriber DB server and uses the content download authentication result received from the content subscriber DB server to determine the authority to download the content. The content data is separated from the information stream and separately stored in the memory unit of the DMB terminal.

When a "content VIEW" command is input from the user, content information stored in a memory unit of the DMB terminal is displayed on the DMB terminal and provided to the user.

On the other hand, these examples are only for illustrating the present invention, the protection scope of the present invention is not limited by these examples.

While the invention has been shown and described in connection with specific embodiments thereof, it will be appreciated that various modifications and variations can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone can grow up easily.

As described above, according to the present invention, a large amount of content can be downloaded inexpensively and quickly using a DMB broadcasting channel. In addition, it is possible to provide content to many users at the same time by reducing the download speed and connection failure that may occur when a plurality of users download the content at the same time, secure additional content providing media using the DMB system and content revenue through Can be increased.

Other effects of the present invention, as well as those described in the above-described embodiments and claims of the present invention, as well as the effects that can occur within a range that can be easily estimated from them and the potential of the potential advantages that contribute to industrial development Add that they will be covered by a wider scope.
