| Abstract: | The system of video monitor for the power line carrier communication was designed.The implementation of system was discussed mainly.In this system,STR912FW44X6 is act as central controller,power line special integration transceiver was used,and modulate and demodulate and demodulate for use multiplex carrier orthogonal frequency division multiplexing technique.MPEG4 video signal through USB was sent to display timely in upper computer.The design is reasonable and applied. |
