摘要:
An apparatus and method are provided for variably transmitting a multimedia stream according to requirements of a client device and the state of a channel. The multimedia stream transmission apparatus includes: a plurality of virtual machines corresponding to the multiple client applications, each of the virtual machines determining a specific parameter set and obtaining a change value for the parameter set from network statistics and a requirement of a corresponding client application; a parameter adjustment unit which adjusts values of parameters used in a network interface by the change value; and the network interface which transmits the multimedia stream based on the adjusted parameters.

A method and apparatus for transmitting data and a method and apparatus for performing a task for process migration are provided. The method of transmitting data includes: determining a data transmission priority using at least one of information relating to data needed to continuously perform a task, that is currently performing, in an external device and information relating to data transmission means; determining transmission methods for each data based on the data transmission priority; and transmitting data to the external device according to the determined transmission methods.
摘要:
A method and apparatus for controlling parameters of a wireless data streaming system are provided. The method of controlling parameters of a wireless data streaming system includes controlling first parameters, which can be controlled in units of individual packets, according to a current packet transmission state in a data stream; transmitting a predefined number of packets using the first parameters and obtaining statistical information regarding use of the first parameters in the transmission of the predefined number of packets; and controlling second parameters, which can be controlled in units of packet groups, with reference to the statistical information and a desired quality of service (QoS).
