Abstract
The radio control sectionnotifies a transmission rate that can be currently set up out of the radio channel transmission rates to the transmission rate decision section. The buffer monitoring sectionmonitors an amount of media data stored in the media reception bufferand when the amount of media data stored exceeds a threshold, the buffer monitoring sectionnotifies it to the transmission rate decision section. When information on the radio channel transmission rate from the radio control sectionshows that the radio channel transmission rate is well within the capacity and when monitoring information from the buffer monitoring sectionshows that the amount of data stored in the media reception bufferdoes not exceed a threshold, the transmission rate decision sectionoutputs a request for increasing the transmission rate of the media data to the control signal transmission/reception section. Thus, even if the maximum rate of the radio channel transmission rate that can be set up decreases due to deterioration of a communication environment, it is possible to prevent data play back from being interrupted.
