According to an embodiment of the present disclosure, a method for analyzing a district heating network including pipes and fluids inside the pipes includes receiving, by a processor, pipe data representing a structure of the pipes; receiving, by the processor, input data on at least one of the physical state of the district heating network and the flow of fluids; calculating, by the processor, data for at least one of the physical state of the district heating network or the flow of fluids using the pipe data and the input data.

Abstract: Disclosed herein is a method of detecting a moving object including: predicting an optical flow in an input image clip using a first deep neural network which is trained to predict an optical flow in an image clip including a plurality of frames; obtaining an optical flow image which reflects a result of the optical flow prediction; and detecting a moving object in the image clip on the basis of the optical flow image using a second deep neural network trained using the first deep neural network.

Abstract: Disclosed are a multi-screen display system and a method of correcting a time synchronization of image signals respectively played by unit display panels. The multi-screen display system includes a multi-screen display apparatus configured to include a plurality of unit display panels and a timing sensing apparatus configured to sense, outside the multi-screen display apparatus, time synchronization information about the unit image frames respectively played by the unit display panels. The timing sensing apparatus calculates a time synchronization error between the unit image frames respectively played by the unit display panels, based on the time synchronization information, and transmits the time synchronization error to the multi-screen display apparatus.

Abstract: Provided is a data transmitting and receiving method in which a display apparatus connectable to a wireless network transmits and receives data to and from a user terminal by using a pointing apparatus. The data transmitting and receiving method includes (a) acquiring position information of a region, pointed by the pointing apparatus, in the display apparatus and (b) transmitting data, corresponding to an object displayed in the region on a screen of the display apparatus, to the user terminal by using the pointing apparatus.

Abstract: A DRM technique interoperability system includes an exporter and an importer. The exporter cancels the DRM technique from the contents to which the DRM technique of a DRM device is applied to generate a contents stream, generates a plurality of packets from the contents stream, and transmits the packets to the importer. The importer receives a plurality of packets from the exporter, generates a contents stream from the plurality of packets, applies a DRM technique of a second DRM device to the contents stream, and provides it to the second DRM device.

Abstract: A method of transmitting and receiving digital signage contents, which is capable of easily transmitting and receiving digital signage contents using a smartphone's application, is disclosed. According to an aspect, the method of transmitting and receiving digital signage contents includes: executing an application; transmitting a message for requesting digital signage contents displayed on a digital signage display device to a digital signage manager through the application; receiving the digital signage contents from the digital signage manager; and outputting the received digital signage contents. Accordingly, a user may easily and quickly receive digital signage contents using a smartphone's application, and also, a plurality of users may simultaneously use the same digital signage contents through their terminals. In addition, it is possible to objectively determine the degrees of users' concern and preference about advertisements and digital signage contents.

Abstract: Methods for Joint Photographic Experts Group (JPEG) 2000 encoding and decoding based on a graphic processing unit (GPU) are provided. The method for JPEG2000 encoding based on a GPU includes receiving input image data from a central processing unit (CPU), encoding the image data, and transferring the encoded image data to the CPU.

Abstract: A DRM technique interoperability system includes an exporter and an importer. The exporter cancels the DRM technique from the contents to which the DRM technique of a DRM device is applied to generate a contents stream, generates a plurality of packets from the contents stream, and transmits the packets to the importer. The importer receives a plurality of packets from the exporter, generates a contents stream from the plurality of packets, applies a DRM technique of a second DRM device to the contents stream, and provides it to the second DRM device.

Abstract: Provided is a system for exchanging contents between a first DRM apparatus and a second DRM apparatus, wherein each of which belongs to different DRM domain. The first DRM apparatus includes unpackaging means for unpackaging first DRM formatted contents into clear resources, metadata, and rights expression; converting means for converting each of the clear resources, metadata, and rights expression into its own predefined neutral format, respectively; generating means for generating neutral formatted contents by combining the converted resources, metadata, and rights expression; adding predetermined header information thereto; and transmitting means for transmitting the neutral-formatted contents to said second DRM apparatus.

Abstract: System and method of a multilingual rights data dictionary is provided. The system and method provides a multilingual RDD registry to local system for translating rights terms. The system includes the RDD registry and processor for translating the rights term by referring to the registry.

Abstract: Disclosed are an apparatus for processing a method-embedded content and a method thereof. The apparatus includes a content packager for packaging a content, metadata, and method, a content unpackager for separating the content, metadata, and method from the packaged content, a method manager section for managing the method extracted from the package, a method execution environment section for securing a safe execution of the method by constructing an environment independent of other parts of a system, an access control section for controlling an access of the method for the content and metadata only in an authenticated software module, an authentication management section for authenticating the software module that intends to access the content, and a content player for processing the method-embedded content. The apparatus provides the content objective environment that can support diverse content applications desired by a user, and maximizes the content applications.

Abstract: A node disjoint path forming method for a hypercube having a damaged node which is capable of using unused nodes (surplus nodes) in an n-number of node disjoint paths each having a length of n with respect to n-dimensional hypercubes more than 4-cube, so that it is possible to obtain an n-number of node disjoint paths each having a length of n even though there are damaged nodes. The method includes the steps of a first step for forming a linear arrangement consisting of an n-number of integers (0, 1, 2, . . .
