When the result set is received from the transmitter / receiver 410, the controller 420 may output and display a media item list of all the result sets received on the display 440.

Meanwhile, when the media item lists are displayed, the input unit 450 may receive a selection of specific media items among all displayed media item lists from the user. Here, the input unit 450 may receive media items for all formats requested by the user as well as a predefined media format.

When the input unit 450 receives specific media items from the user, the input unit 450 may output the received specific media items to the controller 420.

When the controller 420 receives specific media items received from the user from the input unit 450, the controller 420 may configure the received specific media items as a playlist.

The user authentication unit 460 may be connected to the control unit 420. The user authentication unit 460 performs user login authentication for each user account. In other words, it checks the user's account and receives the user's credentials and authority.

In this case, when the user executes the client program, the user login authentication may be performed using the ID and password input through the displayed login window.

The user authentication unit 460 transmits the confirmed user account to the control unit 420 to determine whether to block harmful content.

The control point 400 may configure at least one playlist and store it in the storage 430. The control point 400 configures at least one playlist and stores the playlist in the storage unit 430, and then receives a playlist play from the user through the input unit 450.

When the input unit 450 receives an arbitrary playlist play from the user, the input unit 450 may output an arbitrary playlist play signal to the controller 420. When the controller 420 receives the playback of the media items, the controller 420 may output the input media items to the display unit 440.

Meanwhile, the controller 420 inputs an absence message from the DMA 100 through the transceiver 410 to the media items deleted or moved from the DMS 100 after the playlist play request to the DMS 100. I can receive it. When the control unit 420 receives the absence message, the control unit 420 may output the absence of the corresponding media item to the display unit 440 to notify the user.

As such, the control point 400 may use a content directory service in a DLNA home network to construct a universal playlist according to a user's request regardless of a media format, and is not limited to a specific DMS 100. Content included in the 100 may be configured as a playlist.

On the other hand, the term 'general purpose' means a general purpose within a range that is compatible with AV content sharing between devices in a DLNA home network and does not deviate from the DLNA standard.

The hazard determination unit 470 may be included in the control point 400. Whether the selected content is harmful may be determined by the harmfulness determination unit 470 based on the unique information detected for a predetermined time, such as luminance information, image brightness, hue, and saturation of the frame image.

The hazard determination unit 470 may include at least one of manufacturer / copyright information, hazard warning information, harmful site URL, harmful image information, or viewing restriction age information as hazard determination information.

In addition, the extracted sound source sample may be used to determine whether or not harmful to the content. For example, the harmfulness of the target content may be determined through the sound source repeating pattern.

That is, the hazard determination unit 470 may analyze the vibration displacement of the extracted sound source sample, and determine whether the multimedia record is harmful according to the analysis result. For example, when the playback selected content shows a pattern in which the vibration displacement is repeated a predetermined number of times in a certain playback section, the harmfulness determination unit 470 may determine that the multimedia recording is harmful.

In addition, the harmfulness determination unit 470 may determine whether or not harmful to the multimedia recording by comprehensively considering both the still frame and the sound source sample of the content.

If it is determined that the user authenticated by the user authenticator 460 is a minor, the similarity between the unique information of the content and the harmful threshold information is calculated, and if the calculated similarity is greater than or equal to the threshold, the content is determined to be harmful and the UPnP image is determined. The warning message is output to the MR registered in.

The allowable range of the harmful content may be set in advance and may vary.

Referring to the drawings, the harmful information monitoring device 50 may include a customer information storage unit 51, a transmission unit 52, and a menu providing unit 53.

The customer information storage unit 51 receives and stores a unique identification number of the mobile communication terminal 600 and model information of the mobile communication terminal 600 from the user at the time of registration by the mobile communication terminal user. Here, the type information of the mobile communication terminal 600 may be implemented to read and store from the header of the signal received from the mobile communication terminal 600 connected through the wired or wireless communication network, instead of being received from the user.

When it is determined that the harmful content is harmful content by the hazard determining unit 470, the transmitting unit 52 is transmitted to the transmitting unit 52 of the monitoring server 500, and again, through a wired or wireless network, the mobile communication terminal ( 600) can send a warning message.

In addition, the transmitter 52 transmits the control result of the controller 420 to the mobile communication terminal 600 in a text message. For example, when the reproduction of the DMR 300 is stopped by the content stop command received from the mobile communication terminal 600, the control result may be transmitted to the mobile communication terminal 600 in a text message.

The menu providing unit 53 provides a selection menu to the mobile communication terminal 600 connected through the wired / wireless communication network, and the mobile communication terminal 600 displays the current screen image of the DMR 300 based on the provided selection menu. At least one of capture, on / off, keystroke blocking, and mode switching can be selected. In this case, the transmitter 52 may transmit a control signal for controlling a program to the controller 420 in response to the selection command received from the mobile communication terminal 600.

Here, the text message transmitted to the mobile communication terminal 600 is not limited to the illustrated form and may be modified in various forms.

Therefore, it is possible to check in real time whether harmful information is being reproduced in the DMR from the management supervisor's position, such as a parent who has to stay away from adolescents.

5 is a flowchart illustrating a process of transmitting a warning message to an MR according to an embodiment of the present invention. First, all devices register with UPnP and receive their own IP. Afterwards, the control point (CP) retrieves the content from the media server (MS) to obtain the transmission protocol and the format.

In the next step, the control point obtains a list of protocols and formats supported by the media server, and the media server and the media renderer are connected. After that, the selected content is played.

Next, it is determined whether the video is harmful through image processing of the stream, and when it is determined that the video is harmful, a warning message of the wired and wireless signal is output.
