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

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 provides a data transmission method of a system in an IP based broadcasting network, the data transmission method comprising the steps of: generating an MPEG media transport protocol (MMTP) packet using a media processing unit (MPU) for a service; generating an IP packet using the MMTP packet; generating a layer 2 (L2) packet using the IP packet and generating a layer 1 (L1) packet stream using the L2 packet; and transmitting the L1 packet stream, wherein absolute time information of the system is included in one of a transmission frame of the L1 packet stream and the L2 packet.

Technique for transmitting and receiving system time information in broadcasting system

A transmitting apparatus is provided. The transmitting apparatus includes: a baseband packet (BBP) generator configured to generate a BBP including a header and payload data; a frame generator configured to generate a frame including the BBP; a signal processor configured to signal-process the generated frame; and a transmitter configured to transmit the signal-processed frame. The header includes information about a type of the payload data, whether an additional header exists, a length of the payload data, and a Least Significant Bit (LSB) of the length of the payload data. Therefore, various types of data are mapped on a physical layer based on information included in the header, and data processing efficiency is improved.

Transmitting apparatus, receiving apparatus, and controlling methods thereof

An apparatus and a method for transmitting multimedia data in a hybrid network are provided. The apparatus includes a payload part including at least one of first data synchronized according to a time to be reproduced and second data other than the first data, a first header part including information on the payload part, a packet part for generating a packet, the packet part including a second header part including information on the packet, and a transceiver for generating and transmitting a signal including the payload part, the first header part, and the packet part to the hybrid network.

Apparatus and method for transmitting multimedia data in hybrid network

An apparatus and method for transmitting a multimedia data packet are provided. The method includes receiving Bottom-up Network Abstraction Layer (B-NAL) information from a network entity, determining a media data quality based on the received B-NAL information and generating media data having the determined media data quality, and generating a packet including the generated media data and transmitting the packet to the network entity.

Method and apparatus for transmitting a multimedia data packet using cross-layer optimization

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.

A method for generating a packet of transmitting apparatus is provided. The method includes: setting a value of a Deleted Null Packet (DNP) counter to zero; increasing the value for each deleted null packet preceding a non-null transport stream (TS) packet; and generating a packet comprising a header and a payload, wherein the header includes a DNP field, the payload includes the non-null TS packet, and the value of the DNP counter is used to set the DNP field.
