CLOCK SYNCHRONIZATION OVER A POWERLINE MODEM NETWORK FOR MULTIPLE DEVICES.

摘要

AN APPARATUS AND METHOD OF CLOCK SYNCHRONIZATION OF A POWERLINE MODEM NETWORK FOR A PLURALITY OF DEVICES ARE PROVIDED. A PLURALITY OF DEVICES ARE PROVIDED HAVING A POWERLINE MODEM AND A CLOCK (100). THE POWERLINE MODEM PERMITS COMMUNICATION BETWEEN THE PLURALITY OF DEVICES OVER A POWERLINE NETWORK. A SYNCHRONIZATION MESSAGE IS PROVIDED OVER THE POWERLINE NETWORK (102). THE SYNCHRONIZATION MESSAGE INCLUDES AN INSTRUCTION FOR EACH OF THE PLURALITY OF DEVICES TO UPDATE THEIR CLOCK IN ACCORDANCE WITH A CLOCK TIME PROVIDED IN THE SYNCHRONIZATION MESSAGE (104). A SYNCHRONIZATION DEVICE MAY BE PROVIDED TO UPDATE DEVICE CLOCKS ON A POWERLINE NETWORK. (FIG. 1)
