Method of generating a file describing a bit stream, corresponding device and computer program product. The invention relates to a method of generating a description file (14) of a bit stream (11), from a description scheme (15) describing a structure and a content that are compliant with a predetermined format and comprising a set of attributes and elements, the bit stream (11) consisting of a plurality of fields. According to the invention, such a method comprises: a step for assigning at least one value of at least one identified field of the stream to at least one variable defined by an attribute of the description scheme, called assignment attribute; a step for storing said variable; a step for determining at least one characteristic of at least one element of the description file, from an evaluation of a conditional expression relating to said value; a step for generating a portion of the description file according to the characteristics determined in the determination step.
