Abstract: PURPOSE: A multimedia application system using metadata for a sensory device and a method thereof are provided to add a sensory function about moving picture color reproduction made by an intention of a producer from moving picture content production to final consumption, thereby providing a consumer customized high quality multimedia service. CONSTITUTION: A sensory device engine unit(108) receives SEI(Sensory Effect Information) according to moving picture contents. The sensory device engine unit receives UPI(User Preference Information) of the sensory device(114~120). When DCI(Device Capability Information) is inputted, the sensory device engine unit generates SDC(Sensory Device Commands) for controlling the sensory device based on the input information. A sensory device controller(110) controls each sensory device.

Abstract: PURPOSE: A method for providing a multi angle digital broadcasting service is provided to implement a multi angle service in an IPTV by providing a photographed image of selected angle in 3D stereo image type. CONSTITUTION: A plurality of cameras(10-1 to 10-5) each generates right/left stereo images. A multi angle broadcasting service providing device(20) encodes the photographed images recording from a plurality of cameras in transport stream type. The multi angle broadcast service providing device performs inter-stream synchronization. A user terminal(30) outputs the transport stream through screen. If user requests the multi angle screen, the user terminal outputs the transport stream about the corresponding multi angle screen.

Abstract translation: 目的：提供一种多角度数字广播服务的方法，通过提供3D立体图像类型中所选角度的拍摄图像来实现IPTV中的多角度服务。 构成：多个照相机（10-1〜10-5）各自生成右/左立体图像。 多角度广播服务提供装置（20）对从传输流类型的多个摄像机记录的拍摄图像进行编码。 多角度广播服务提供装置执行流间同步。 用户终端（30）通过屏幕输出传输流。 如果用户请求多角度屏幕，则用户终端输出关于相应多角度屏幕的传输流。

Abstract: PURPOSE: A transmission tree building method and a device for the same are provided to apply transmission structure composition method of different policies to composition nodes with different operation mode when multiuser real-time IP(Internet Protocol) TV broadcast service is supplied in an overlay transmission structure. CONSTITUTION: An information reception unit(100) receives agent information from an agent. An operation mode check unit(122) checks the operation mode of the agent based on the received information. A level allocation unit(124) allocates a level to the agent by reflecting the operation mode. A tree composition unit(130) compose a transmission tree between agents based on the level information. If broadcast registration or reception request is received from the agent, a list provision unit(140) generates a candidate node list based on the level information of the agents and provides the list to the agents.
