Metadata Scheme For Personalized Data Broadcasting Service And, Method And System For Data Broadcasting Service Using The Same

A metadata scheme for a data broadcasting service, comprising:

• an interactive content service (InteractiveContentService) element which describes whether a data broadcasting is a uni-directional service or a bi-directional service;
• a rendering style (RenderingStyle) element which describes properties of the data broadcasting displayed on a screen of a user;
• an update cycle (UpdateCycle) element which describes a content update period of the data broadcasting;
• and
• a package, an item or a component on the data broadcasting service information including the three elements.

A method for providing a data broadcasting service, comprising the steps of:

• a) forming a package including an interactive content service element which describes whether a data broadcasting is a uni-directional service or a bi-directional service, a rendering style element which describes properties of the data broadcasting displayed on a screen of a user, and an update cycle element which describes a content update period of the data broadcasting;
• b) transmitting and receiving the package;
• and
• c) showing data broadcasting service information to a user by using the data broadcasting service metadata included in the received package and receiving a related content.

A user terminal for receiving a data broadcasting service in a data broadcasting service system, comprising:

• a receiving unit for receiving an encoded package which includes an interactive content service element which describes whether a data broadcasting is a uni-directional service or a bi-directional service, a rendering style element which describes properties of the data broadcasting displayed on a screen of a user, and an update cycle element which describes a content update period of the data broadcasting;
• a decoding unit for decoding the encoded package to thereby obtain decoded data;
• a package information extracting and storing unit for acquiring various information included in the package, which is package information, from the decoded data and storing the package information;
• and
• a middleware application unit for transmitting information on the data broadcasting by using the package information and acquiring an application.
