摘要:
The present invention relates to a method and an apparatus for allocating resources in a communication system using an asset delivery characteristics (ADC) message so as to improve efficiency in network resource usage. A method for allocating network resources in a transmission unit of a communication system according to the present invention comprises the steps of: generating an ADC message that includes a parameter value representing a transmission characteristic of a single asset; and transmitting the generated ADC message, wherein the generated ADC message is updated periodically or aperiodically with respect to the asset.

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.
摘要:
A transmitting apparatus and an operating method for the apparatus in a multimedia system are provided. The operating method includes inputting at least one network layer packet, generating a link layer packet based on the at least one network layer packet, and transmitting the link layer packet. The link layer packet includes a header including information indicating a packet type of the at least one network layer packet, information indicating whether the link layer packet includes a single network layer packet, and information indicating an identifier related to the at least one network layer packet.

摘要:
Provided are a method and a device for transmitting and receiving multimedia data. The present invention comprises: receiving of multimedia data and confirming of loss data; determining, with respect to the degree of the loss of the received data, of whether or not the lost data can be recovered by means of application layer forward error correction (AL-FEC); if data recovery by means of the AL-FEC is not possible, making of an automatic retransmission request (ARQ) with respect to the lost data; and receiving of data retransmitted with respect to the ARQ and recovering of the lost data.
摘要:
A method for transmitting media data-related information at a transmitting entity in a multimedia transmission system including at least one intermediate node is provided. The method includes generating information of traffic, which corresponds to at least one media data configuring a multimedia service, for each valid time period, and transmitting the media data-related information comprising the information of traffic to a receiving entity through the at least one intermediate node.
摘要:
A vehicle control apparatus and method using private medical information, and a mobile terminal are provided. An optimized driving environment is provided by searching controllable vehicle control nodes in a vehicle, upon reception of a driver's private medical information; determining if there is vehicle control information for controlling the searched vehicle control node; and controlling the vehicle control nodes using vehicle control information that corresponds to the received driver's private medical information if there is the vehicle control information for controlling the searched control nodes.
摘要:
A method for providing a multimedia service based on unicast, according to the present invention, comprises the steps of: packetizing multimedia data; when a terminal accesses the multimedia service, determining a mode for transmitting the multimedia data to the terminal; generating a signaling message including information on the determined mode, and transmitting the signaling message to the terminal; and transmitting first data among the packetized multimedia data to the terminal on the basis of the determined mode.
摘要:
A method for transmitting multimedia according to the present disclosure comprises: a step of transmitting a first message including fixed delay information and buffer information with respect to a receiving device; and a step of transmitting a packet relating to the multimedia and including a transmission time stamp, wherein a first packet is sent out from a digital buffer of the receiving device at a time determined by adding up the transmission time stamp and the fixed delay information.
