In this case, the event occurrence requirement may include the number of multimedia data to be transmitted. That is, an event may be generated when the number of multimedia data to be transmitted is greater than or equal to a certain level. However, the event occurrence requirements can be variously set by the operator.

2 is a detailed block diagram of a multimedia providing system according to the present invention.

The multimedia providing system according to the present invention includes a subscriber database (DB) 24 that stores subscriber information largely, a content DB server 23 that receives and stores multimedia data from a CP, and a content DB server 23. A synchronization server 22 which selects a transmission target karaoke device or an outdoor advertisement device according to the generated event, and provides information on the selected karaoke device or outdoor advertisement device and transmission target multimedia data, and transfers the synchronization server 22 from the synchronization server 22. Download server for reading the information of the transmission target karaoke device or outdoor advertising device and the transmission target multimedia data from the content DB server 23, transmit the information to the karaoke device or outdoor advertising device, and store the transmission history in the subscriber DB 24 ( 21).

The subscriber DB 24 includes information on karaoke devices or outdoor advertising devices (for example, subscriber personal information, IP information, etc.) subscribed to the service, multimedia data information currently stored in karaoke devices or outdoor advertising devices, and transmitted. History information and the like are stored.

The content DB server 23 receives the multimedia data from the content provider CP and stores the multimedia data in the database. When the event occurrence requirement is satisfied, the content DB server 23 transmits the event occurrence to the synchronization server 22. When the multimedia data information to be transmitted is transmitted from the download server 21, the corresponding multimedia data is read and provided to the download server 21.

When the synchronization server 22 is notified of the occurrence of the event from the content DB server 23, the synchronization server 22 refers to the subscriber DB and selects a transmission target karaoke device or an outdoor advertisement device. Then, the information on the selected karaoke device or the outdoor advertising device and the multimedia data to be transmitted are provided to the download server 21. Here, the process of selecting the transmission target karaoke device or the outdoor advertisement device by the synchronization server 22 will be described in detail.

When the synchronization server 22 is notified of the event from the content DB server 23, the synchronization server 22 confirms the multimedia data information included in the event. The synchronization server 22 checks the transmission history information in the subscriber DB. As a result of the check, the karaoke device or the outdoor advertisement device having the transmission history information before the event occurrence time is selected as the transmission target remote device. On the other hand, in another embodiment, when the synchronization server 22 is notified of the occurrence of the event, the synchronization server 22 receives information (eg, IP information and retained multimedia information) about a karaoke device or an outdoor advertising device, which is a remote device to be transmitted from the subscriber DB. Acquire. Then, the multimedia data information held by the transmission target remote device is compared with the multimedia data information stored in the current content DB server. If there is a missing multimedia data in the remote device as a result of the comparison, the information of the remote device and the multimedia data to be transmitted are transmitted to the download server 21.

On the other hand, the synchronization server 22 accesses the remote device at regular intervals and compares the multimedia data information held by the remote device with the subscriber-owned multimedia data information stored in the subscriber DB 24 to perform synchronization. As a result of the synchronization, when there is a difference in the retained multimedia data information, the synchronization server 22 may request the download server 21 to transmit the multimedia data to the remote device.

When the download server 21 is provided with the transmission target remote device and the transmission target multimedia data information from the synchronization server 22, the download server 21 communicates with the remote device and receives the multimedia data from the content DB server 23. To send. Then, the result of the transmission and the transmission history are transmitted to the subscriber DB 24, and the subscriber DB 24 updates the multimedia data information and the transmission history information held by the corresponding remote device.

Meanwhile, in the present invention, the download server 21 and the synchronization server 22 are separately configured, but this may be configured to perform two functions in one server. That is, it is possible to have a function of performing synchronization for determining a transmission target remote device according to an event occurrence in one server and a download function for transmitting multimedia data to the remote device.

3 is a flowchart illustrating a method of providing multimedia data using the portable Internet according to the present invention.

First, the server checks (102) whether an event occurs in the standby state (101). The event occurrence condition may include a set inspection period or the number of newly added multimedia data. If it is confirmed that the event does not occur, it is continuously in the standby state 101. If the event occurs, the process for selecting a transmission target remote device is performed. Look at this.

When the event occurs, the server first checks the subscriber information (103). Then, the transmission target remote device is selected from the confirmation result (104). Here, the server checks the transmission history information among the subscriber's information, and selects all the remote devices having the transmission history before the event occurrence time as the transmission target remote device. Alternatively, by checking subscriber information, the remote device may be selected as a transmission target remote device if the remote device compares the multimedia data information held by the remote device with the multimedia data information stored in the content DB server. In the case of using the former method, there is an advantage in that the remote device to be transmitted can be selected within a short time, while the multimedia data stored in the remote device and the multimedia data stored in the server may be inconsistent. The latter method can match the multimedia data stored in the remote device with the multimedia data stored in the server, but it has a disadvantage in that the selection process of the remote device to be transmitted can take a long time. Of course, if the latter method does not check whether all the multimedia information is synchronized, but only if the remote device has the multimedia data included in the event occurs, it may be able to select the remote device to be transmitted in a short time.

When the transmission target remote device is determined, the server checks whether communication with the transmission target remote device is possible (105). That is, the server sends a specific command to the remote device via the portable Internet base station, and determines that the remote device can communicate if it responds. As a result of the check, if communication with the transmission target remote device is possible, the server reads the transmission target multimedia data from the DB server and transmits it to the remote device (106). If the transmission is performed normally, the transmission result, transmission history, and transmitted multimedia data information are transmitted to the subscriber DB. Accordingly, the subscriber DB is updated (107).

On the other hand, if communication with the transmission target remote device is impossible (105), the server checks (108) whether communication with another transmission target device is possible. When the transmission is completed for all the transmission target remote devices, the server returns to the standby state (109).

On the other hand, a function not described in the present invention, that is, a retransmission is repeatedly performed a predetermined number of times when the transmission fails, and the processing in the case of continuous failure uses a conventional technique. The multimedia data provided in the present invention includes moving picture information.

As described above, according to the present invention, multimedia data can be provided using a portable Internet network to a karaoke device or an outdoor advertising device located at a remote location, so that the data stored in the remote device can be updated at low cost and high speed. It can be effective.
