Method for encoding a stream of bits of a binary source signal into a stream of bits of a binary channel signal |
摘要 |
The invention relates to a method for encoding a stream of bits of a signal relating to a binary source into a stream of bits of a signal relating to a binary channel, the binary source comprising a main source and a secondary source, the main source being encoded in a main channel and the secondary source being encoded in a secondary channel, the secondary channel being embedded in the main channel in order to form the binary channel, wherein the binary channel is divided in blocks, each block comprising a number of user bits and that in at least one of the blocks the secondary channel also is used for encoding non-user bits. The invention further relates to an encoder to carry out this method, a decoder to decode the stream of bits relating to the binary channel and a record carrier provided with the encoded signal in the form of optically detectable marks. By means of the invention for example non-user data can be added that are used to prevent unauthorized copying.
