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

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

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 disclosure relates to a technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and the Internet of Things (IoT). The present disclosure may be utilized for an intelligent service (smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of the technology. The present disclosure relates to a method for supporting interworking between heterogeneous systems, the method comprising the steps of: transmitting, to a first device, a message requesting a subscription to a resource; receiving, from the first device, a notification message indicating that the resource of the first device has been changed; transmitting, to a second device, a request message for monitoring a resource of the second device; and receiving a response message indicating the resource of the second device in response to the transmission of the request message, wherein the resource of the first device is associated with the second device.

A method and apparatus for providing a trick play service in a hypertext transfer protocol (HTTP) adaptive streaming (HAS) architecture for adaptively streaming media data according to fluctuation of a streaming environment are provided. The method at a server includes: generating a media presentation description (MPD) file including information about at least one piece of trick play data; transmitting the MPD file to a client; and transmitting the at least one piece of trick play data to the client in response to a request by the client based on the MPD file. The method at a client includes: receiving a media presentation description (MPD) file including information about at least one piece of trick play data; and receiving the at least one piece of trick play data from a server based on the MPD file.

Method and apparatus for providing trick play service

Methods and apparatus are provided for providing a content service of a control device. A first request related to a content service is received. First information for a location corresponding to the first request and second information for a session corresponding to the first request are acquired based on the first request. A second request is transmitted to a content delivery network (CDN) identified based on the first information and the second information, based on the first request.

Methods and apparatus for selection of content delivery network (CDN) based on user location

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.

A method and apparatus for adaptively transmitting and receiving media data to a streaming environment by segmenting into segments a plurality of media data, which is generated by encoding content to have different qualities.

Method and apparatus for adaptive streaming using segmentation

Methods and apparatuses are provided for providing a Control User Interface (CUI) by a terminal. A location of the terminal is identified. The CUI, including information corresponding to the location of the terminal, is displayed. A command for controlling a device is generated based on the displayed CUI. The command is transmitted to the device or to a server connected to the device. The information corresponding to the location of the terminal is received from the device or from the server.

Methods and apparatus for remote control service in a network

A method for receiving additional information from a device in a broadcast communication system is provided. The method includes receiving broadcast information provided from a broadcast service provider over a broadcast channel, extracting application information from the broadcast information, acquiring location information for the additional information associated with a broadcast content from the application information, and transmitting the location information for the additional information to a peer device for displaying the additional information.
