Abstract:
1. A method for transmitting a video sequence from a transmitting terminal including at least one short-range radio interface and one long-range radio interface towards at least one receiving terminal, characterized in that it comprises the following steps: segmenting said video sequence into a base layer making it possible to obtain a low-quality video sequence and at least one improvement layer, complementary to said base layer, and making it possible to obtain a better quality video sequence in combination with the base layer, transmission, by said long-range radio interface of the transmitting terminal, of at least the entire base layer towards said receiving terminal, transmission, by said short-range radio interface of the transmitting terminal, of at least the entire improvement layer towards at least one cooperation terminal comprising at least one short-range radio interface and one long-range radio interface, transmission, by said long-range radio interface of said cooperation terminal, of at least the entire improvement layer towards said receiving terminal; wherein said long-range radio interface of the transmitting terminal communicates according to communication frames successively comprising descending frames and ascending frames, and characterized in that said transmission by the short-range radio interface of the transmitting terminal of the improvement layer towards said cooperation terminal layer comprises a step for transmitting data towards said cooperation terminal during at least one of said descending frames, and in that said transmission by the long-range radio interface of the transmitting terminal of the base layer and said transmission, by the long-range radio interface of said cooperation terminal, of the improvement layer comprise steps for transmitting data from said base and improvement layers, respectively, during at least one of said ascending frames.
