Abstract:
A method and an apparatus for adaptively coping with a network environment are provided. The method and apparatus includes a packet descriptor for forwarding of Media Transport (MMT) packets in a network process of a switch or a router for processing MMT packets forwarding content expressed in a structure of an MMT standard. The method of managing a queue in a broadcasting system includes receiving a Moving Picture Experts Group (MPEG) MMT packet, obtaining a header of the MMT packet, and queuing the MMT packet according to a type value of a bitrate included in the header of the MMT packet.
Abstract:
An interface is provided for providing a media service. The interface includes an encapsulation layer for encapsulating coded media data, a delivery layer for transmitting the encapsulated media data to another entity, and a control layer for controlling transmission of the media data.
Abstract:
A method and an apparatus of processing a media file for an Augmented Reality (AR) service are provided. The method includes storing a media file including information about an event to provide the AR service, and providing the media file. The information about the event includes identification information about an event item and information about an event type.
Abstract:
A method and apparatus for transmitting and receiving content is provided. A method for transmitting content in a transmitter includes generating a file with one or more packages including at least one asset, and transmitting the generated file to a terminal.
Abstract:
A method and an apparatus for synchronizing media data and auxiliary data received by a service through a broadcast network or a communication network in a multimedia broadcast service are provided. The method includes receiving regular media data provided for a broadcast service, receiving and storing control information regarding adjunct media data comprising auxiliary data regarding the regular media data, determining location information of the adjunct media data included in the control information, and receiving and storing the adjunct media data according to the location information. If an identifier of the adjunct media data is included in a header of the regular media data, reading the stored adjunct media data corresponding to the identifier of the adjunct media data, and executing the adjunct media data in synchronization with the regular media data according to synchronization information included in the header.
Abstract:
A method for transmitting media data in a Moving Picture Experts Group (MPEG) Media Transport (MMT) system is provided. The method includes receiving a Media Processing Unit (MPU) fragmented into one or more Media Fragment Units (MFUs), generating one or more multimedia data packets each including a packet header and a payload, based on the MPU, and transmitting the one or more multimedia data packets to a terminal. A payload header included in the payload includes identification information indicating an MPU to which at least one MPU included in the payload belongs, and a counter indicating the number of the at least one MPU.
Abstract:
A method for transmitting data of multimedia content is provided. A packet including a packet header and a packet payload is identified. The packet payload includes an access unit including media data related to the multimedia content and information related to the access unit. Control information for delivery and consumption of the multimedia content is identified. The identified packet is transmitted. The identified control information is transmitted separately from the packet. The control information includes type information related to content in the multimedia content, discovery information related to the content in the multimedia content, and relationship information related to contents in the multimedia content.
Abstract:
A method for receiving a multimedia service is provided. The method includes receiving service specific information for at least one multimedia service provided from different networks, selecting one service based on the service specific information, and receiving the selected service. The service specific information includes one of a first service map table including information about at least one service which is transmitted over a plurality of logical channels, and a second service map table including information about at least one service which is transmitted over a single logical channel. Each of the first and second service map tables includes asset-related information.
