Abstract:
A multi-vision virtualization system includes a multi-vision virtualization server and two or more scene clients. The multi-vision virtualization server includes a multi-vision virtualization server configured to generate virtual machines for decoding processes based on image content segments, generate synchronous reproduction information for synchronization between two or more scene clients, transmit the generated synchronous reproduction information to a first scene client among the two or more scene clients, and decode the image content segments to generate decoded image segments; and the two or more scene clients including the first scene client that parses the received synchronous reproduction information, and shares the parsed synchronous reproduction information with remaining scene clients, and being configured to reproduce the decoded image segments on screens based on the parsed synchronous reproduction information.
Abstract:
There are provided a concept of mixing and synchronizing a plurality of pieces of content and of providing mixed content to an N-screen terminal, a method for overcoming limitations of a mobile terminal using a thin-client technique based on cloud computing and an apparatus for providing mixed content based on cloud computing. The apparatus for providing mixed content based on cloud computing includes a content server configured to, in response to a content request, execute a piece of content and provide content execution results, a content access middleware configured to allocate one or more virtual terminals to the content server, receive the content execution results from the content server and synchronize the content execution results, and a virtual convergence gateway server configured to receive the synchronized content execution results, generate mixed content and provide the mixed content to the user terminal using a split-screen method and a multi-screen method.
Abstract:
Provided is an object migration system for web-based content service migration according to the present invention including: two or more web-based terminals configured to deliver a request for web-based content service migration including object information and service web-based content through a received virtualization object and a web page; a virtualization server configured to allocate a new virtual machine on the basis of the object information received from one of the two or more web-based terminals and deliver a virtualization object generated from content corresponding to the received object information to another of the two or more web-based terminals, the another being a destination terminal corresponding to the received object information; and a web server configured to provide the web page to the two or more web-based terminals. The destination terminal services the same web-based content as serviced by the one web-based terminal, at the same time point.
Abstract:
A system for providing a distributed device resource-object-connection service based on a service delivery platform (SDP), the system including: an SDP configured to define distributed service functions as enablers, generate a convergence service by combining the enablers, and provide the generated convergence service; and a proxy configured to connect a distributed device and an SDP to allow the SDP to use the distributed device as a resource, and define and use the distributed device as an enabler.
Abstract:
A user terminal for preventing communication interruption during handoff in an information-centric network is provided. The user terminal includes a connection registration unit configured to register the user terminal in an access node for connection to the access node, and a communication interruption prevention unit configured to receive, from the access node in which the user terminal is registered, zone information including identification information on other access nodes that are candidate handoff targets of the user terminal, and transfer the zone information to a counterpart communication device that currently performs communication, wherein the user terminal receives a message from the counterpart communication device through one of the other access nodes that are candidate handoff targets during the handoff. Accordingly, communication interruption is prevented.
Abstract:
A transcoding server is provided, and the transcoding server includes a receiving unit configured to receive image data and additional information via a communication network; an additional middleware configured to process the received additional information; a decoding unit configured to decode the received image data; an overlay-mixer configured to generate integrated image data by overlaying the decoded image data with the processed additional information; an encoding unit configured to encode the generated integrated data image; and a transmitting unit configured to transmit the encoded integrated image data to one or more terminals.
Abstract:
There are provided a file management server for ensuring security in a cloud computing environment, and a file management method thereof. The file management server includes: a file registration unit configured to store a file in a plurality of chunk servers, and to manage a security level of the file; and a file search unit configured to receive a file access request from a client module, to check a security level of a file corresponding to the file access request, to notify, if the security level of the file is equal to or higher than a predetermined security level, the file's owner that a request for accessing the file has been made.
Abstract:
Provided are a load balancing apparatus and method based on estimation of resource usage. The load balancing apparatus includes a service platform configured to generate service resource information including information on respective necessary resource amounts for providing a plurality of pieces of content, a service processor configured to have one or at least two service units, and generate service unit information including information on amounts of resources allocated to the respective one or at least two service units, and a load balancer configured to compare the received service resource information with the received service unit information on the basis of a received service identification (ID) number and select a service unit for providing a service corresponding to the received service ID number from among the one or at least two service units.
Abstract:
An apparatus and method for providing multimedia content service are provided. A method for providing an image service using at least two screens of different types in an N-screen service providing apparatus includes: separating and extracting independent visual objects from an image based on depth values; grouping the extracted independent visual objects into a number of groups and composing scenes with the respective groups of visual objects; and selectively reproducing one or more scenes with the groups of visual objects on at least two screens in response to a user interaction event.
Abstract:
Provided is an input signal converting device, including a device input receiving unit configured to receive an input signal from an input device, and extract a type of the input device from which the received input signal is generated and an input event corresponding to the input signal, an input event converting unit configured to obtain an output event in a corresponding user terminal and a type of a user terminal corresponding to the extracted input device type and input event, and a device input transmitting unit configured to generate an output signal corresponding to the output event to be output to the user terminal, and deliver the generated output signal to the user terminal.
