Abstract: A communication system that can improve communication quality by accurately re-creating reproduction timing at the receiving end even at the time of receiving VBR data or in the case of the occurrence of a packet loss. A send rate recognition section recognizes a send rate from a time stamp. A memory stores data. A dummy data addition section adds dummy data for correcting the difference between a read rate set for reading out data from the memory and the send rate to the data written to the memory. A read clock generation section generates a read clock which is equal to the read rate. A dummy data removal section removes the dummy data from the data read out from the memory on the basis of the read clock.

Abstract: If a radio LAN apparatus moves from a communication range of a first access point to a communication range of a second access point, and if communication link between the radio LAN apparatus and the first access point is broken, a memory control section stops transmitting data to the first access point. At this time, data to be transmitted to the first access point are not deleted from memory. After the radio LAN apparatus enters the communication range of the second access point, the memory control section resumes transmission of the data stored in the memory. Thereafter, the next data are transmitted. Thus, the data is transmitted in proper sequence.
