Abstract: A method and apparatus provides a multi-screen based multi-dimensional game service using a home network and a home server. The method includes determining a resolution of a game screen to be served based on terminal information provided from a user terminal, storing a view on a user location in a multi-dimensional shared game space as a game session, generating an object for the view based on the determined resolution, performing multi-view rendering using multi-dimensional scene data and a user game input, capturing video and audio generated through the multi-view rendering, encoding the captured video and audio, and transmitting encoded video and audio to the user terminal.

Abstract: A system for providing virtual AV service includes a local device middleware (LDM) media server which stores AV contents and a resource cooperation server (RCS) which separates the AV contents from the LDM media server into video contents and audio contents. The video contents and the audio contents are reproduced by an LDM video renderer and an LDM audio renderer, respectively. An LDM control point (LDMCP) controls the LDM media server and the LDM media renderers using the LDM protocol and a virtual device ensembler (VDE) controls the RCS and the LDMCP.
