A method and apparatus for transmitting and receiving LASeR contents are provided, in which content including at least one of a scene element and a scene element set that includes the scene element is received, for use in scene composition, and a scene is composed by selecting at least one of the at least one of the scene element and the scene element set included in the content according to at least one of a terminal type, a user preference, and a content-serviced party.
摘要:
A method and apparatus for supporting mobility in a mobile broadcasting system in which Electronic Service Guide (ESG) discovery is required. The mobility support is classified into three ways according to three different aspects. The first way is to provide roaming information for a local IPDC operator having a roaming partner among local IPDC operators. In the second way, a terminal transmits a query message for requesting transmission of information on a particular local IPDC operator, and receives information on the particular local IPDC operator in response thereto. The third way is to provide the terminal with type information of an ESG; an access type of which is classified according to provision of a roaming service. The roaming information, the information on the particular local IPDC operator and the type information of the ESG, which are provided to the terminal from the mobile broadcasting system, can be provided in an ESG bootstrap level.
摘要:
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 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 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 for changing a subscription status of a service in a mobile communication system, and a system thereof. A method is provided for changing a subscription status of a service by a terminal in a mobile communication system. The method includes transmitting a pause request message, in which a pause period of the subscription status is included, to a network entity; receiving, from the network entity, a pause response message including therein a possible pause period for the pause period included in the pause request message, and a trigger for changing validity for a Long-term Key stored in the terminal; and changing validity for the Long-term Key using the trigger for the possible pause period included in the pause response message.
摘要:
A system and method for transmitting broadcast service data in a digital broadcasting system. The method includes setting a flag indicating a service area representative of coverage where broadcast service data is provided, for each broadcast service; and transmitting broadcast service information including the flag and a Transport Stream (TS) including the broadcast service data.
摘要:
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.
摘要:
Disclosed is a method for transmitting an Electronic Service Guide (ESG) in a Digital Video Broadcasting (DVB) system, the method includes collecting ESG data to be transmitted; when a multi-stream mode is used in order to transmit the ESG data, setting parameters to be transmitted, and setting the number of IP streams to be used in the multi-stream mode; setting a signaling field indicating use or non-use of at least one partitioning rule in each IP stream; setting at least one of a start field value and an end field value for all fields of said each IP stream used according to a corresponding partitioning rule; if setup of the start field value and the end field value is completed, encoding a partition declaration field of an ESG init container including the set values; and transmitting the encoded ESG data to a terminal.
