Abstract
An apparatus for monitoring harmful content in a DLNA system according to an embodiment includes a control point; A monitoring server connected to the control point; And a DMR connected to the control point and playing multimedia content.
Description
The present invention relates to an apparatus for monitoring harmful content in a DLNA system and a method for monitoring harmful information using the same.
DLNA is an abbreviation of Digital Living Network Alliance, which establishes a standard that connects digital AV / C devices or personal computers connected to the home network so that data such as music, movies, and still images can be mutually compatible. Is a standardization organization for digital information technology products.
1 is a block diagram of an embodiment of a general DLNA network. The DLNA network of FIG. 1 is based on the UPnP (Universal Plug and Play) protocol, and includes wired and wireless devices including devices connected to the DLNA network and communicating in a format based on the UPnP protocol (hereinafter, referred to as UPnP devices). Network 101.
The UPnP device includes a digital media server (DMS) 103, a digital media player (DMP) 105, and a digital media renderer (DMR) 107.
In particular, the standard for interconnecting home network devices, called the "DLNA Guidelines" for the standardization of DLNA networks, refers to the device sector of DLNA as DMS (Digital Media Server) and DMP (Digital Media Player) or DMR (Digital Media Renderer). The connection conditions between DMS and DMP or DMR are defined.
In other words, DLNA guidelines are based on UPnP as a core technology, so that digital information technology products such as home appliances, PCs, and wireless devices having different brands can be connected to each other through wired and wireless home networks to share contents. The design principles of digital information technology products to be supported are summarized and defined.
The DMP is a DMR including a UPnP Control Point (CP). The DMP serves to select, control, and execute a selected media content, which is a function of a Media Renderer Device (MRD) and a Media Renderer Control Point (MRCP).
The DMS serves to provide a function of a media server device (MSD) in the UPnP AV area, that is, a digital media content. The main purpose of the DMS is a control point (CP) which is a UI application (User Interface Application). A media content item is retrieved to enable a DLNA network user to display or distribute the content. The DMS is equipped with a broadcast receiving device and broadcast middleware for receiving digital broadcast, and includes a VCR, a CD player, a DVD player, an MP3 player, a set top box (STB), a TV tuner, a radio tuner, a PC, and the like.
The DMR plays a role of executing the selected media, and includes an AV / C device such as a TV, a stereo speaker, and the like.
On the other hand, the contents reproduced in the DMR include contents such as pornography and violent materials aimed at commercial use, so that anyone can easily access them, and the degree of exposure of such contents to minors is a new social situation. It is causing a problem.
According to an embodiment of the present invention, harmful information (manufacturer / copyright information, harmful warning information, harmful site URL, harmful image information, viewing restriction age information, etc.) inserted into the multimedia file is identified to determine whether the multimedia file is harmful. If it is determined that the content is harmful to adolescents, a warning message is output to all DMRs registered on UPnP.
Here, UPnP (Universal Plug and Play) is a technology that enables communication between information appliances connected to a network without complicated setting procedures, and allows other devices to automatically find a service owned by one device.
An apparatus for monitoring harmful content in a DLNA system according to an embodiment includes a control point; A monitoring server connected to the control point; And a DMR connected to the control point and playing multimedia content.
According to an embodiment of the present invention, it is possible to monitor whether the harmful information is connected from a distance by determining whether the content played through the MR is harmful, and outputting a warning message to all the DMRs registered on the UPnP when it is determined that the harmful content is harmful. Will be.
By applying harmful content blocking according to the user account, adolescents can block access to harmful content, and the parent who is the supervisor can check whether or not access to harmful information in real time.

Hereinafter, an apparatus and method for constructing a playlist in a digital living network alliance (DLNA) home network according to the present invention will be described in detail with reference to the accompanying drawings.
2 is a diagram illustrating a configuration of a DLNA home network according to an embodiment of the present invention.
As shown in FIG. 2, the DLNA home network may be configured to include a
In DLNA based on UPnP, a device class is set for each device. The components of FIG. 2 are classified and named according to the device class. Device classes are classified according to which functions they support regardless of their physical characteristics. Since a device may provide various functions, a device may belong to several device classes.
The digital media server (DMS) 100 is a device for a server in which a UPnP media server is embedded, and can provide media on a DLNA home network.
The digital media player (DMP) 200 may provide a function of selecting and controlling media on a DLNA home network and playing back the selected media. Such a
The DMR (Digital Media Renderer) 300 is a device for playing content received from a home network. As described above, the
In addition, the types of DLNA devices classified according to functions and physical characteristics may include a DVD player, a TV, a DVR, a mobile phone, a printer, a camera, and the like. These various types of devices may be the

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.
