Wireless communication apparatus

摘要

A wireless communication apparatus is provided which is capable of performing synchronous transmission of a stream such as a video signal and therefore performing high-quality video transmission. The sending side generates time information based on a count of a beacon timer, adds the time information to a data packet of a video signal and sends the data packet. The receiving side, using PLL based on a timer count contained in a beacon, generates a clock having a higher frequency every time a beacon signal is received. The receiving side counts the clocks and accordingly generates new time information. This time information is compared with the time information added to the received data packet of the video signal, and the data packet is outputted only when the two match with each other.
