<p>PROBLEM TO BE SOLVED: To provide a radio communication system that can ensure the continuity of data and surely transfer the data to a receiver side even on the occurrence of interruption of a radio wave on the way of communication. SOLUTION: In the radio communication system consisting of an image pickup device 10a and recording and reproducing device 20, the image pickup device 10 transmits video data to the recording and reproducing device 20 through radio communication. In this case, a temporary storage device 16 of the image pickup device 10 stores the data at that time and transfers the data to a recorder 15 by regarding the data as unarrived data when the image pickup device 10 cannot detect an acknowledgement signal sent form the recording and reproducing device 20 in a prescribed time. At the restoration to a communication enabled state, the image pickup device 10 transmits data sent in real time including the unarrived data in the recorder 15. Thus, the recording and reproducing device 20 can obtain the video data in a complete form and can correctly reproduce the video data in time sequence by assembling the received video data on a time base later.</p> |
