Abstract:
1. A transmission method for transmitting on a serial transmission path a data code encoded by superimposing a clock signal for decoding on data to be transmitted, the encoded data code of a first bit length having a predetermined number of bits, said transmission method using a plurality of control codes to be exchanged on said serial transmission path between a sender side and a receiver side, each of said plurality of control codes is of a second bit length having a smaller number of bits than said first bit length, and said transmission method comprising the steps of: inspecting a bit string in groups of bits of said second bit length in order to determine whether one of said plurality of control codes is present in a serial signal received from said serial transmission path or not; selecting a second control code to be sent to said serial transmission path based on a determination in said inspecting step that a first control code is present; sending, onto said serial transmission path, a bit string containing at least said second control code to be sent based on the result of the determination in said inspecting step; and receiving the data code by inspecting said bit string in groups of bits of said first bit length in response to the determination that the first control code received from the opposite side in said determining step indicates the start of transmission of the data.
