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

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

A display device and an image processing method thereof are provided. An image processing method of a display device, according to the present disclosure, comprises the steps of: dividing a display unit of the display device into a plurality of regions; measuring brightness expression performance of the display device, including a value of a relation between the average brightness of the display unit and the brightness of one region among the plurality of regions; calculating an average brightness of an image inputted to the display device; mapping, to the measured brightness expression performance, the calculated average brightness of the inputted image; adjusting the brightness of a region, excluding an emphasized region, of the inputted image so as to generate an adjusted image; and outputting the adjusted image.

Method for processing image, and display device

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 MFU included in the payload belongs, and a counter indicating the number of the at least one MFU.

An apparatus is provided for transmitting multimedia content. The apparatus includes a communication interface and a controller coupled to the communication interface. The controller is configured to identify a packet including a packet header and a packet payload. The packet payload includes an access unit including media data related to the multimedia content and information related to the access unit. The controller is also configured to identify control information for delivery and consumption of the multimedia content, and transmit the identified packet and the identified control information. The information related to the access unit includes information on a sequence number of the access unit.

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 interne 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.

A method and apparatus are provided for receiving service discovery information in a client in a hybrid delivery multimedia transmission system, the method including receiving service discovery information related to a service and comprising service type information indicating that the service is provided by a plurality of channels including a first channel of a first network and a second channel of a second network, the second channel being different from the first channel, in a plurality of networks including the first network and the second network, different from the first network, and parsing the service type information.
