Patent ID: 7340022

Claim:
A method for transmitting packets comprising a synchronization part and a payload part, the payload part comprising a first data sequence and a second data sequence, said method comprising: sending and encoding the first data sequence using a first encoding scheme; sending the synchronization part using the first encoding scheme; encoding and sending the payload part using a second encoding scheme on a sender side; receiving and decoding the first data sequence; detecting the synchronization part and synchronizing and adapting said receiving and decoding; receiving and decoding the second data sequence on a receiver side; sending a shortened synchronization part using the first encoding scheme, followed by sending the first data sequence using the first encoding scheme, followed by sending the second data sequence using the second encoding scheme instead on the sender side; detecting the shortened synchronization part; receiving and decoding the first data sequence; detecting the end of the first data sequence and synchronizing and adapting said receiving and decoding; and receiving and decoding the second data sequence on the receiver side, wherein the first encoding scheme is a line coding enabling the synchronization in the receiver.
