Abstract: The invention relates to a method to reproduce, on at least one client terminal, at least one data flow comprising a plurality of encoded entities, each associated with at least one composition time stamp, said method comprising steps of decoding said flow(s), so as to obtain at least one decoded flow comprising a plurality of decoded entities, and composing of said decoded entities, at the times defined by said composition time stamps. According to the invention, for at least one of said encoded entities, said decoding step is anticipated with respect to said composition time stamp, if a composition context associated with said encoded entity is identical to a current composition context.

Abstract: The inventive method for reading data received in the protected form consists in transmitting at least certain protected data to a protection removing tool. The protected data is retrieved from a buffer memory of a read stream of said data and is transmitted to the protection removing tool by a security message router. To transmit between said security message router and the protection removing tool, data is recorded in assigned transfer frames.

Abstract: The invention relates to a method to reproduce, on at least one client terminal, at least one data flow comprising a plurality of encoded entities, each associated with at least one composition time stamp, said method comprising steps consisting of: decoding said flow(s), so as to obtain at least one decoded flow comprising a plurality of decoded entities; composing of said decoded entities, at the times defined by said composition time stamps. According to the invention, for at least one of said encoded entities, said decoding step is anticipated with respect to said composition time stamp, if a composition context associated with said encoded entity verifies at least one predetermined criterion.
