ABSTRACT:
A method is described for recording an audiovisual information stream comprising a plurality of alternative parts (VS1; VS2; VS3) and at least one common part (AS1; AS2; GS1; GS2), wherein the alternative parts of the information stream are recorded in an interleaved manner. Each of the alternative information stream parts is divided into alternative information stream blocks (VSB1(i); VSB2(i); VSB3(i)). Each of the common information stream parts is divided into common information stream blocks (ASBI(i); ASB2(i); GSB1(i); GSB2(i)). The information stream is recorded as a succession of consecutive interleaved units (IU(i)), each interleaved unit comprising one corresponding block (ASB1(i); ASB2(i); GSB1(i); GSB2(i)) of each of the common information stream parts (AS1; AS2; GS1; GS2) and one corresponding block (VSBI(i); VSB2(i); VSB3(i)) of each of the alternative information stream parts (VS1; VS2; VS3), the common information stream blocks being separate from the alternative information stream blocks.
