System for providing media service using sensor network and metadata
First Claim
1. A system for providing media service using a sensor network and metadata, the sensor network having a plurality of sensor network nodes connected to a media server and one or more media devices, respectively, wherein:
- the media server comprises a media information storage unit for storing media information about locations and details of media content, a sensor interface unit for providing interface with a corresponding sensor network node, which is connected to the media server, for transmission and reception of data, a metadata storage unit for storing metadata about a user'"'"'s preference information and the media devices, receiving the metadata from the media devices through the sensor interface unit, comparing previously stored metadata with the received metadata, and storing updated metadata, a content selection unit for retrieving the media information from the media information storage unit using the metadata stored in the metadata storage unit, and selecting media content to be transmitted to the media devices, and a content transmission unit for transmitting the selected media content to the media devices;
the media devices each comprise a content reception unit for receiving the media content transmitted from the content transmission unit of the media server, a sensor interface unit for providing interface with a corresponding sensor network node, which is connected to the media devices, for transmission and reception of data, and a metadata storage unit for storing the metadata about the user'"'"'s preference information and the media devices, receiving the metadata from the media server through the sensor interface unit, comparing previously stored metadata with the received metadata and storing updated metadata; and
the sensor network nodes each comprise a sensor network interface unit for providing interface with sensor network nodes of other devices, which exist within the media service providing system, for transmission and reception of data, a device interface unit for providing interface with a corresponding media device for transmission and reception of data, and a metadata storage unit for receiving metadata from the corresponding media device through the device interface unit and storing the metadata, and receiving the metadata from other sensor network nodes through the sensor network interface unit, comparing previously stored metadata with the received metadata and storing updated metadata.

Abstract
Disclosed herein is a system for providing media service using a sensor network and metadata. The sensor network includes a plurality of sensor network nodes connected to a media server and one or more media devices, respectively. The media server includes a media information storage unit, a sensor interface unit, a metadata storage unit, a content selection unit and a content transmission unit. The media device includes a content reception unit, a sensor interface unit and a metadata storage unit. The sensor network nodes each include a network interface unit, a device interface unit and a metadata storage unit. In detail, the metadata are input to the corresponding sensor network node, media content desired by a user is intelligently retrieved based on the metadata, and the media content desired by the user is provided to the media device desired by the user, including a mobile media device in the user'"'"'s possession, at a time desired by the user.
