Abstract
A transmission method for transmitting data containing inhibition code data that cannot be recorded in a digital recording and/or reproducing apparatus. The method includes a step of converting the inhibition code data into special code data and ID code data having redundancy and not containing the inhibition code data, a step of converting the special code data into two special code data and one special code data and a step of directly outputting data other than the inhibition code data and the special code data. The method enables transmission of the totality of coded data inclusive of the inhibition code data that cannot be recorded.
Claims8
A transmission method for transmitting input code data containing inhibition code data that is not proper to be recorded in a digital recording and/or reproducing apparatus, comprising
- converting at least the inhibition code data into code data having a redundancy and not containing the inhibition code data according to a conversion rule, and
- performing an inverse conversion according to an inverse conversion rule which is the reverse of the conversion rule.
A transmission device for transmitting input code data containing inhibition code data that is not proper to be recorded in a digital recording and/or reproducing apparatus, comprising
- converting means for converting at least the inhibition code data into code data consisting of a special code data which is not the inhibition code data and an ID code data which is neither the inhibition code data nor the special code data, and
- inverse conversion means for performing inverse conversion which is a counterpart operation of the conversion performed by said converting means.
