Abstract: An apparatus for providing an augmented broadcasting service and an apparatus for receiving the augmented broadcasting service in a hybrid broadcasting environment. The apparatus for providing the augmented broadcasting service includes: a real-time data provider configured to provide real-time data through a first transmission network; an augmented content provider configured to provide augmented content through a second transmission network, wherein the augmented content is to be synchronized with the real-time data; and a multiplexer configured to multiplex the real-time data, the augmented content metadata and timing information for synchronization between the real-time data and the augmented content metadata, and output resulting data.

Abstract: An audience selection type augmented broadcasting service providing apparatus and method is provided. The audience selection type augmented broadcasting service providing apparatus may include an augmented broadcast producing server to process a production process of augmented contents to provide the augmented broadcasting service, for broadcast contents, a broadcasting server to multiplex and transmit the broadcast contents and metadata for the augmented broadcasting service, and an augmented content receiving terminal to process the augmented contents based on the metadata for the augmented broadcasting service, while playing the broadcast contents.

Abstract: Disclosed is a method of providing a video contents service including calculating conversion information indicating a relation between a projection area and an area corresponding to the projection area in order to project video contents on the area corresponding to the projection area which is a partial area within a prepared image in a user image photographed by a user terminal; and transmitting the calculated conversion information to the user terminal.

Abstract: An augmented broadcasting stream transmission device and method and an augmented broadcasting service providing device and method capable of ensuring that augmented broadcasting metadata arrive at a receive terminal in a time more rapid as compared to a corresponding video frame by a predetermined time are provided.

Abstract: Provided is an apparatus and method for providing metadata in advance in order to gain a time required for a receiving terminal to receive augmented content corresponding to the metadata, based on the metadata received over a communication network in a bidirectional digital broadcast. The apparatus may provide a service before a predetermined time for a channel bound service that provides augmented content associated with a broadcast program, or a time-restraint service, such as a quiz program, for which an access to a website may required by a predetermined time. Also, the apparatus may provide metadata of a subsequent program in advance, before a predetermined time when transmitting the broadcast program, whereby a receiving terminal may receive associated information in advance, and a viewer may utilize a website or an augmented content service of a corresponding program, simultaneously with viewing the corresponding program.

Abstract: A method and apparatus for providing supplementary information about content in a broadcasting system are provided. A method of a reception terminal providing supplementary information about content includes receiving content and metadata, extracting an indicator for indicating whether supplementary information about the content exists or not from the metadata, determining whether the supplementary information about the content exists or not based on the indicator, outputting the supplementary information about an appearance element of the content in association with the content based on the metadata, accessing a server for providing the supplementary information about the to appearance element, based on the metadata when an instruction to download the supplementary information about the appearance element is received, and downloading the supplementary information about the appearance element from the server and storing the downloaded supplementary information.

Abstract: The system includes a metadata generation apparatus for generating metadata to designate a specific space and time in and on which a speech balloon or a music book will be displayed on broadcasting content, a multiplexing broadcasting server for multiplexing the metadata received from the metadata generation apparatus and the broadcasting content and sending the multiplexed result to a reception apparatus, an augmented content providing apparatus for sending the speech balloon suitable for speech included in the broadcasting content or the music book suitable for music included in the broadcasting content to the reception apparatus, and the reception apparatus for displaying the broadcasting content and displaying the augmented content in a specific space and time of the broadcasting content based on the metadata.

Abstract: Disclosed are a method for allocating priority to resources, and a method and apparatus for operating resources using the same. The method for allocating priority to resources includes: selecting a resource block including at least one unit; determining a priority level of the selected resource block by reflecting a retrieval rate (or recovery rate) including a retrieval frequency and a retrieval period of the selected resource block; and allotting the determined priority level to the selected resource block.

Abstract: In the present invention, an expert system is coupled to the fault management function of a switching system for diagnosing various faults which occur in an electronic switching system and an interface module is coupled to the expert system, so that a user can diagnose a fault of the switching system and monitor a result of the fault. The expert system of the present invention has a knowledge base including information relating to faults of the switching system and when a fault occurs in the switching system, the expert system outputs information of the fault occurrence to a multimedia screen so that a user can recognize a fault immediately and diagnose the fault of the switching system.
