Estimating the term…
The invention relates to a method of performing a processing of a multimedia content. The method according to the invention comprises performing said processing by analyzing a structured description of a bit stream obtained from coding said multimedia content. The description is advantageously written in a markup language such as XML. In a first embodiment said processing comprises the generation of coding data exclusive of the coding format, relating to the bit stream and adding them to the description (cut between video sequences, character depending on or independent of the coding of elementary video units, presentation time and decoding time . . . ). In a second embodiment said processing is an applicable processing (reading of a video stream based on a point defined by a user, copying, pasting, video sequence concatenation . . . ).
A method of performing a processing (T1) of at least one multimedia content (CT), characterized in that it comprises a syntax analysis step (P1) of analyzing a structured description (DN) of a bit stream (BIN) obtained from coding said multimedia content in accordance with a certain coding format, to recover in said description one or more coding data (D1) included in said coding format, and a step of executing said processing from the one or the plurality of said coding data.
A system comprising a first entity (E1) intended to produce a bit stream obtained from coding a multimedia content in accordance with a certain coding format and a structured description of said bit stream, and a second entity (E2) intended to perform a syntax analysis of said description for recovering in said description one or more coding data included in said coding format, and for performing a processing of said multimedia content from the one or the plurality of said coding data.
Equipment (E2) comprising syntax analysis means for analyzing a description structured in a bit stream obtained from coding a multimedia content in accordance with a certain coding format, for recovering in said description one or more coding data included in said coding format, and means for executing a processing of said multimedia content from the one or the plurality of said coding data.
