Assignee: TENDYRON CORPORATION
Field: Telecommunications (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 4:
5. A power line data transmitting method, comprising the zero crossing point signal output method according to claim 1, and further comprising: subsequent to said continuously outputting the zero crossing point signals with the interval being the zero crossing point signal output interval T,
determining a 1st zero crossing point time t based on the zero crossing point signals, and determining a start time of transmitting a synchronization signal of a data packet to be transmitted based on the 1st zero crossing point time, wherein the start time of transmitting the synchronization signal of the data packet to be transmitted is t+t1, t+t1 is earlier than a 2nd zero crossing point time t+T, t+T is contained in a time period from a time point of transmitting a first synchronization bit signal to a time point of transmitting a last synchronization bit signal, and t1 is a first predetermined fixed value; and sequentially transmitting data bit signals of the data packet to be transmitted.
