Patent ID: 7706380

Claim:
A data transmission method of transmitting a high-speed data signal, in which two or more data are disposed and separated by no-signal intervals each having a same predetermined data length, from a transmit station connected to a network to a receive station connected to another network, said method comprising: a dividing step of dividing each of said plurality of data into two or more low-speed data in the transmit station, so as to create two or more sequences of low-speed data which are separated by no-signal intervals each having the predetermined data length; a fixed-pattern adding step of adding a fixed pattern for detecting a head or an end of each low-speed data included in each of said two or more sequences of low-speed data to each of said no-signal intervals included in each of said two or more sequences of low-speed data in the transmit station, so as to create two or more sequences of fixed-pattern-added low-speed data; and a transmitting step of transmitting, from the transmit station, said two or more sequences of fixed-pattern-added low-speed data to said receive station connected to said other network.
