Terminal, system and method for providing augmented broadcasting service using augmented scene description data

A terminal for providing augmented broadcasting service, comprising:

• a broadcast receiver configured to receive, via a broadcast network, broadcast content and augmented broadcasting service information including information indicating that it is possible to provide augmented broadcasting service, information on an augmented content providing server, and information on an augmented scene description data providing server for presenting augmented content;
• an augmented broadcasting service data acquisitor configured to acquire augmented scene description data and augmented content selected by a user from the augmented content providing server and the augmented scene description data providing server via a wired/wireless communication network according to the augmented broadcasting service information received by the broadcast receiver;
• and
• an augmented broadcast synthesizer configured to output the augmented content to be overlaid on the broadcast content received by the broadcast receiver according to the augmented scene description data acquired by the augmented broadcasting service data acquisitor, wherein
• the broadcast content includes passage time information,
• the augmented content includes an augmented scene object, and
• the augmented scene description data includes information for presenting the augmented scene object according to the passage time information.

A method of providing augmented broadcasting service, comprising:

• when broadcast content provided by a broadcast content providing server is a program providing augmented broadcasting service, transmitting, at an augmented broadcasting service information providing server, augmented broadcasting service information including information indicating that it is possible to provide augmented broadcasting service, information on an augmented content providing server, and information on an augmented scene description data providing server for presenting augmented content;
• when a terminal accesses the augmented content providing server, providing, at the augmented content providing server, the augmented content;
• and
• when the terminal accesses the augmented scene description data providing server, providing, at the augmented scene description data providing server, augmented scene description data, wherein
• the broadcast content includes passage time information,
• the augmented content includes an augmented scene object, and
• the augmented scene description data includes information for presenting the augmented scene object according to the passage time information.

A system for providing augmented broadcasting service, comprising:

• a broadcast content providing server;
• an augmented broadcasting service information providing server configured to transmit augmented broadcasting service information including information indicating that it is possible to provide augmented broadcasting service, augmented content providing server information, and augmented scene description data providing server information for presenting augmented content, when broadcast content provided by the broadcast content providing server is a program providing augmented broadcasting service;
• an augmented content providing server configured to provide the augmented content when a terminal accesses the augmented content providing server;
• and
• an augmented scene description data providing server configured to provide augmented scene description data when the terminal accesses the augmented scene description data providing server, wherein
• the broadcast content includes passage time information,
• the augmented content includes an augmented scene object, and
• the augmented scene description data includes information for presenting the augmented scene object according to the passage time information.
