Abstract:
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.
Abstract:
The present disclosure relates to a broadcasting method of a transmission apparatus in an IP-based broadcast network, the method comprising: an operation of generating an MPEG media transport protocol (MMTP) packet using a media processing unit (MPU) for a service; an operation of determining an IP session identifier for identifying an IP session for the service, and generating an IP packet using the MMTP packet and the IP session identifier; and an operation of transmitting the generated IP packet in a radio frequency (RF) channel, wherein the IP session identifier maps a combination of a source IP address, a destination IP address and a destination port for the IP packet, and at least one of the IP session identifier, the source IP address, the destination IP address and the destination port is transferred through a first layer signaling.
Abstract:
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.
Abstract:
A method and apparatus for updating firmware of terminals in a mobile broadcast system including a Broadcast Service Distribution/Adaptation fragment (BSDA) and a Broadcast service Subscription Management (BSM) are provided. The method includes transmitting a request for creation of a content fragment, by the BSM, to the BSDA; delivering, by the BSM, a firmware package to the BSDA; broadcasting, by the BSDA, a service guide including the content fragment to at least one terminal; and distributing, by the BSDA, the firmware package to the at least one terminal.
Abstract:
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.
Abstract:
A method and apparatus for providing a broadcasting service are provided. The method includes receiving, by a first terminal, channel information of a program selected by a user from a second terminal, detecting a frequency of the selected program from a mapping table that maps the channel information to a corresponding frequency, locking a tuner of the first terminal to the detected frequency, and receiving a broadcasting service of the program from a broadcasting network server.
Abstract:
An apparatus and method for providing a broadcasting and communication convergence service are provided. The method includes acquiring address information about an Internet server configured to provide an application customized based on user information and/or device information about a terminal, transmitting an application request message to the Internet server using the address information, receiving the customized application on a broadcast channel from the Internet server in response to the application request message, and consuming the customized application.
Abstract:
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.
