ABSTRACT:
A radio communication system according to the present invention includes a video/audio transmitter (1) and a video/audio receiver (2) for transmission/reception of data including video data and audio data at a predetermined bit rate. The video/audio receiver (2) has an error information generation section (18) for detecting a communication state according to a signal from the video/audio transmitter (1). The video/audio transmitter (1) has a transmission section (6) for transmitting data while controlling to change the bit rate according to the communication state detected by the video/audio receiver (2). Unless the communication state satisfies a predetermined criterion, the transmission section (6) temporarily lowers the bit rate for transmitting the data to the video/audio receiver (2). Thus, even when the communication state deteriorates, it is possible to minimize deterioration of the video and audio data and transmit data without lowering the quality of the entire video and audio transmitted.
