In order to achieve short-range wireless video transmission,this paper proposes a short-range wireless video transmission scheme based on MPEG-4 code.The data collected from a CMOS camera OV7620 are processed by a dedicated MPEG-4 encoder ML86410 to obtain the MPEG-4 data stream of less than 2 Mbit·s-1,which is then sent through the wireless nRF24L01 under the control of the FPGA controller.The receiver uses the same chips nRF24LU1 to receive wireless data with USB protocol and interface.Then the stream can be sent into PC for display.Circuit board simulation achieves good images,which shows that the wireless transmission of video circuit is successful.
