摘要：
A digital signal transmission method in which a digital signal having a header block of a predetermined length is transmitted. The header is comprised of a synchronization signal and auxiliary data. The auxiliary data is made up of first data or second data and a redundant error detection code. The redundant code indicates whether the block contains the first data as the auxiliary data or the second data as the auxiliary data so that different headers having different contents can be distinguished by the reproduction apparatus.
