The maruchibitsuto huorenjitsuku spacing which has the encoding detection key

摘要

As for this invention, the process which imbeds the auxiliary data with type of the maruchibitsuto payload inside the host signal, relation it regards with the process which encodes the detection key which is attached. Furthermore, this invention regards extracting the auxiliary data with type of the maruchibitsuto payload from the data signal. The auxiliary data is imbedded to the host signal with process below. First the reference spacing is supplied, after that, the encoding detection key which in only the reference spacing relation is attached is formed. The encoding detection key can be the version where spacing was scrambled. With further process, the multiple bit spacing is formed, the maruchibitsuto payload is encoded in the reference spacing. Lastly, the multiple bit spacing is imbedded to the host signal.
