Abstract: The invention relates to a method for the diagnostic testing of a mobile telephone terminal (10) including: a UICC card (13) containing a stored test application, and a contactless communication module (12) which can exchange data with a contactless unit (20) by retromodulation of a signal transmitted by the unit, said method comprising a test operation whereby the unit: emits a test application selection request; detects a response indicating application selection confirmation or failure, transmitted by the mobile telephone terminal; and determines the operating state of the UICC card or of the terminal as a function of the response detected.

Abstract: A process for distributing audiovisual sequences may involve generating a modified main stream from an audiovisual sequence as well as complementary information that may enable equipment receiving the modified main stream and the complementary information to synthesize the audiovisual sequence. The modified main stream and the complementary information may be separately transmitted to the equipment.

Abstract: A process for distributing audiovisual sequences according to an original stream format having a succession of frames, the original stream on which an analysis is made, prior to transmission to client equipment, to generate a first modified main stream and complementary information, then the modified main stream and the complementary information are transmitted separately to equipment of our addressee, and for which a synthesis of a stream in the original format is calculated on the equipment of the addressee as a function of the modified main stream and the complementary information, wherein the analysis of the original stream comprises: an operation application stage comprising modelings generating sequences of pseudorandom values with known parameters, a stage for the extraction of original data as a function of pseudorandom sequences, and a stage for storage of parameters of modelings in the complementary information.
