摘要:
A method for transmitting multimedia data delivery characteristics information by a multimedia data transmission apparatus in a multimedia communication system is provided. The method includes transmitting, to a multimedia data reception apparatus, an element indicating whether multimedia data delivery characteristics information denoting information related to a Quality of Service (QoS) for multimedia data is included, and the multimedia data delivery characteristics information if the element indicates that the multimedia data delivery characteristics information is included.
摘要:
The present invention provides a method and a device for transferring transmission characteristic information of multimedia data. According to the present invention, characteristic information on media data which can be partitioned into media processing units (MPUs) is generated in a predetermined number of MPUs, and the generated characteristic information and a flag indicative of the existence of the generated characteristic information are inserted into the media data such that the characteristic information is transferred. Thus, since the characteristic information for transmission can be used according to each media data unit of a small time unit, more effective QoS control is possible in a situation when a transmission environment dynamically changes, such as a mobile network.
摘要:
A method of transmitting a data packet of a multimedia service is provided. The method includes generating a media characteristic corresponding to a single media content component or aggregated media characteristics corresponding to a plurality of multimedia content components, obtaining information used for generating the data packet from the generated media characteristics or aggregated media characteristics, and generating the data packet based on the obtained information used for generating the data packet and transmitting the generated data packet.
摘要:
An apparatus and a method for providing an adaptive multimedia service in a mobile communication system are provided. The method of providing a multimedia service includes collecting user-preference-aware information, device-capability-aware information, and network-aware information, generating a packet according to a correlation among the user-preference-aware information, the device-capability-aware information, and the network-aware information, and providing a multimedia service according to the generated packet.
摘要:
According to the present invention, a method for transmitting a multimedia data packet comprises the following processes: receiving bottom-up network abstraction layer (B-NAL) information from a network entity; determining the quality of media data based on the received B-NAL information, and generating media data having the determined quality; and generating a packet for the generated media data, and transmitting the packet.
