摘要:
Provided is a broadcasting system based on a network using an Internet protocol (IP). In the broadcasting system, a broadcast transmitter previously transmits first access information including a first network address for transmitting a general notification message and second access information associated with management of the broadcasting system, to a broadcast receiver. If a general notification event occurs, the general notification message is generated and the generated general notification message is transmitted to the broadcast receiver via one of a broadcast network and an interaction network using the first network address. The broadcast receiver receives a general notification message based on the first network address in data received from the broadcast transmitter.

An apparatus and method for providing a security service for UI applications in a network system. In a network supporting a user interface, encryption-unneeded data is distinguished from data in which security identifier is specified, that indicates a need for security between a server and a communication device, and the distinguished data is transmitted over a security channel and a general channel separately.

A method for providing a notification message in a transmitter of a mobile broadcast system supporting an interaction channel is disclosed. Upon an occurrence of a notification event, a first means generates a notification message, and generates at least one delivery request message including a target address based on subscription information of the corresponding terminal, using the generated notification message. A second means determines a channel over which it will deliver a notification message to the corresponding terminal based on the target address, and delivers the notification message over the determined channel.

A method and apparatus is provided for defining and transmitting/receiving a presentation fragment including therein a requirement for a scheme of displaying an Electronic Service Guide (ESG) in a digital broadcast system. The transmission method includes generating a presentation fragment including therein a requirement for terminal presentation; inputting the presentation fragment including therein a requirement for terminal presentation to an ESG data model through encoding; and transmitting the ESG data model to the terminal. The presentation fragment includes ESG's display control information at the terminal.
摘要:
A method and apparatus for transmitting and receiving an Electronic Service Guide (ESG) of an interaction channel in a Digital Video Broadcasting (DVB) system are provided. In order to transmit the ESG, ESG data about acquisition information is collected and it is determined whether a service associated with the ESG data is transmitted on an interaction channel. If the service is transmitted on the interaction channel, service access information needed to the interaction channel is set in a first field added for setting interaction channel information in an acquisition fragment of the ESG data. If the service is not transmitted on the interaction channel, service access information needed to receive a unidirectional broadcast channel is set in a second field configured to transmit information for accessing a service stream of the unidirectional broadcast channel in an old-version acquisition fragment. The ESG data including the acquisition fragment with the service access information set is transmitted to a receiving terminal.

Disclosed is a method for transmitting a notification message in a mobile broadcast system that includes transmitting common notification message channel information necessary for receiving a common notification message for all users capable of receiving broadcast services, along with an Electronic Service Guide (ESG) for the broadcast services or a control signal for the broadcast services; transmitting specific notification message channel information necessary for receiving a specific notification message for a specific user group to a terminal in the specific user group along with the ESG; generating at least one of the common notification message and the specific notification message; and transmitting the generated notification message to the terminal using the corresponding channel information.
摘要:
A method and apparatus for providing a preview service using an ESG in a digital broadcasting system are provided. Metadata of ongoing broadcasting services are collected. In the presence of preview data for the preview service among the collected metadata, information associated with the preview service is set in a Related Material element included in at least one of a service fragment, a content fragment, and a service bundle fragment in an ESG data model and representing referenced media data. ESG data including the fragments are generated and sent to a terminal.

A method is provided for controlling access to a resource of a Remote User Interface (RUI) server in an RUI client of an RUI system. The method includes sending a request for an RUI page for controlling the resource to the RUI server and receiving the RUI page, generating a connection to a Mutual Exclusion (MUTEX) of the RUI server, which corresponds to the resource, using the received RUT page, and sending a request for MUTEX locking for restricting access to the resource to the RUI server.
摘要:
A method and apparatus for creating and displaying a media file. A computer-readable recording medium is disclosed for storing stereoscopic content having two or more tracks and stereoscopic video-related information of each track in the stereoscopic content. The medium includes a duplication indication field indicating duplication of stereoscopic video-related information of each track in the stereoscopic content, and a track reference field including information used to connect a current track to at least one other track to which the current rack refers.
摘要:
A user interface method and apparatus for a Rich Media service in a terminal. A decoder decodes a received stream to check a header of the received stream. A renderer adaptively composes a scene using scene composition elements of the received stream, according to adaptation information in the header checked by the decoder, and a display displays the adaptively composed scene.
