Then, the transmission control unit 204 receives a response packet (that is, a response packet recording the terminal detailed model name) transmitted from the portable terminal 100 through the communication unit 202 (step 510).

In addition, the transmission control unit 204 provides a control signal for analyzing the received response packet to the information analysis unit 210, and after analyzing the received response packet, the information analysis unit 210 extracts the terminal detailed model name. The analysis result is provided to the transmission control unit 204, whereby the transmission control unit 204 recognizes the detailed model name of the portable terminal 100 (step 512).

On the other hand, as a result of the check in the step 506, when the connection to the portable terminal 100 (that is, connected to the portable terminal 100 via the USB interface) is displayed on the display unit 206 After that, a USB protocol packet transmitted from the portable terminal 100 is received through the communication unit 202 (step 514).

In addition, the transmission control unit 204 provides a control signal for analyzing the received USB protocol packet (that is, a packet including device descriptor information) to the information analyzer 210, and the information analyzer 210 receives the control signal. After analyzing the USB protocol packet, the device descriptor information is extracted from the USB protocol packet, and the analysis result obtained by extracting the detailed model name of the terminal by referring to the idVendor field and the idProduct field from the extracted device descriptor information is provided to the transmission controller 204. Accordingly, the transmission control unit 204 recognizes the detailed model name of the portable terminal 100 (step 516). The USB protocol packet includes device descriptor information provided to a USB host by a USB client defined in the USB protocol standard specification. The device descriptor information describes, for example, an idVendor field describing a manufacturer ID and a detailed model ID. It may include an idProduct field and the like.

As an example, FIG. 7 illustrates an example of extracting device descriptor information of a content providing apparatus, an MP3 player, and a mobile phone according to another embodiment of the present invention. FIG. 7 illustrates device descriptor information of each of the MP3 player and the mobile phone by field. Through this, information for recognizing the detailed model of the terminal can be extracted.

On the other hand, the transmission control unit 204 checks whether it is a model that can be supported according to the detailed model of the recognized portable terminal 100, and if it is a model that can support the portable terminal 100 connected through the communication unit 202 to the removable disk mode Check if it is set (step 518).

As a result of the check in the step 518, the mode change control signal is transmitted to the portable terminal 100 through the communication unit 202 when it is not the removable disk mode, and the transmission control unit 204 receives the mode from the portable terminal 100. The change confirmation signal is received to confirm the change to the removable disk mode (step 520). Here, when the model does not support automatic change to the removable disk mode, the transmission controller 204 may display the mode switching guide screen according to the detailed model of the portable terminal 100 through the display unit 206.

On the other hand, when it is confirmed in the step 518 that the portable terminal 100 is in the removable disk mode or the changed state to the removable disk mode, the transmission control unit 204 provides a plurality of contents that can be provided according to the detailed model of the terminal. When the list is displayed through the display unit 206 and an operation signal for requesting transmission of specific content is input from the input unit 208, the memory information and the transmission received from the portable terminal 100 through the communication unit 202 are transmitted. The content of the requested content is displayed on the display unit 206, and if the content can be transmitted, the content is extracted from the content storage unit 212 and transmitted to the portable terminal 100 through the communication unit 202 (step 522). ).

In this case, when content transmission is impossible, that is, when the capacity of the content requested to be transmitted exceeds the memory capacity of the portable terminal 100, the display unit 206 may be displayed or connected to another memory device to connect another memory device. The informing message may be displayed on the display unit 206.

Therefore, when the content providing device is connected to the mobile terminal through the serial interface or the USB interface for providing the content, the response model or the USB protocol packet transmitted from the mobile terminal is analyzed to automatically recognize the detailed model of the terminal, thereby responding to the content transmission request. Accordingly, the content can be extracted and easily transmitted to the portable terminal.

Meanwhile, in the above-described exemplary embodiments, the portable terminal 100 is described as a mobile communication terminal (ie, a mobile phone). However, the portable terminal 100 is a PMP or another external memory device. For example, the process as described above may be performed by omitting the process of checking the supportable model and changing the removable disk mode.

In the foregoing description, various embodiments of the present invention have been described and described. However, the present invention is not necessarily limited thereto, and a person having ordinary skill in the art to which the present invention pertains can make various changes without departing from the technical spirit of the present invention. It will be readily appreciated that branch substitutions, modifications and variations are possible.
