Device and method for transmitting or receiving media resource identification information in communication system

A method of a transmission device in a multimedia system comprises the steps of: detecting a request for changing first-type data into second-type data while the first-type data is being played at a given point in time; and transmitting, before the second-type data is played, information necessary for replaying data, among the first-type data, played prior to the given point in time, and/or data, among the second-type data, played prior to the given point in time.

Device and method for transmitting and receiving signal in multimedia system

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.

Method and apparatus for transmitting media data in multimedia transport system

An apparatus and a method for providing information used for generating and consuming multimedia content in a broadcast system supporting a multimedia service based on an Internet protocol are provided. The method includes composing a message type field containing information indicating on a type of control information contained in the control message, composing a length field containing information on the length of the control message, composing optional fields having different values according to the type of the control information, and composing a payload field containing content of the control information.

Apparatus and method for configuring a control message in a broadcast system

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.

Method and apparatus for transmitting and receiving content

The present invention relates to an apparatus and a method for configuring a control message in a broadcasting system for supporting a multimedia service based on an internet protocol. To this end, control information to be recorded in a payload of a control message to be configured is generated based on a table selected from among a plurality of tables for defining the information related to the generation and consumption of a hybrid content when a message type of the control message to be configured is determined to be a type for providing information related to the generation and consumption of a hybrid content. In addition, the information related to the type of the selected table is recorded in an optional field of the control message to be configured.

Apparatus and method for configuring control message in broadcasting system

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.

Interface apparatus and method for transmitting and receiving media data

There are provided a method and apparatus for delivering transport characteristics of multimedia data. According to an aspect of the present invention, transport characteristics of media data that can be divided in a unit of a Media Processing Unit (MPU) are created in a unit of a predetermined number of MPUs, the created transport characteristics and a flag indicating presence or absence of the created transport characteristics are inserted into the media data, and the resultant media data is delivered. Accordingly, by using transport characteristics in units of media data unit groups, each media data unit corresponding to a short time length, it is possible to effectively control Quality of Service (QoS) in a dynamically changing transport environment, like a mobile network.

Apparatus and method for delivering transport characteristics of multimedia data

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.

Method and apparatus for transmitting and receiving multimedia service

The present disclosure relates to a method of transmitting multimedia content in a broadcast communication system, and comprises the steps of: identifying protocol information mapped for each service corresponding to multimedia content; transmitting service-related information including the identified protocol information mapped for each service; and transmitting multimedia content corresponding to related services to a receiving side by using the identified protocol.

Method and apparatus for transmitting and receiving signaling information associated with multimedia content

A method for providing a broadcast service is provided. The method includes transmitting a user datagram protocol (UDP)/internet protocol (IP) packet including a first message, the first message containing information about a message to be signed and transmitted, and transmitting a moving picture experts group (MPEG) media transport protocol (MMTP) packet including a second message, the second message containing information about the broadcast service and information indicating whether the information about the broadcast service is signed. The first message includes an identifier of a key used to verify a signature of the message to be transmitted and signed and an identifier of a hash algorithm used to calculate a hash value of the message to be transmitted and signed.
