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 (ASB 1(i); ASB2(i); GSB1(i); GSB2(i)) of each of the common information stream parts (AS1; AS2; GS 1; 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.
Procédé d'enregistrement d'un flux d'informations audiovisuelles comportant une pluralité de parties alternatives (VS1; VS2; VS3) et au moins une partie commune (AS1; AS2; GS1; GS2), les parties alternatives du flux d'informations étant enregistrées de manière entrelacée. Chacune des parties alternatives du flux d'informations est divisée en blocs alternatifs de flux d'informations (VSB1(i); VSB2(i); VSB3(i)). Chacune des parties communes du flux d'informations est divisée en blocs communs de flux d'informations (ASB1(i); ASB2(i); GSB1(i); GSB2(i)). Le flux d'informations est enregistré sous forme d'une succession d'unités entrelacées consécutives (IU(i)), dont chacune comporte un bloc correspondant (ASB 1(i); ASB2(i); GSB1(i); GSB2(i)) de chacune des parties communes du flux d'informations (AS1; AS2; GS1; GS2) et un bloc correspondant (VSB1(i); VSB2(i); VSB3(i)) de chacune des parties alternatives du flux d'informations (VS1; VS2; VS3), les blocs communs étant séparés des blocs alternatifs.
