Apparatus and method for transmitting multimedia streaming

A multimedia streaming transmission apparatus and method are provided to control a parameter of a MAC layer by reflecting characteristics of data desired to be transmitted in various multimedia data communication devices. A data source unit(110) outputs a multimedia data stream. A frame separating unit(120) separates and outputs the data stream according to the type of a video frame included in the data stream. A parameter controller(140) selects a parameter set for controlling individual transmission of the separated data streams by using a parameter for controlling a transmission layer and outputs it. A network interface unit(130) controls transmission of the separated data streams by the selected parameter set.
