Abstract: The invention relates to a method for accessing to a service offered by a service provider on a communications network (2) from a terminal (T) through a multichannel access network (1), consisting in delivering by the service provider information at least concerning data about the address (@, P) of said service in the communications network (2) to a mediation module (4), in determining by the mediation module (4) at least one identifier (Sld, SClds) of a channel usable by the terminal (T) for accessing to the service and associating said channel identifier to information delivered by the service provider (S) and in receiving by the terminal (T) said channel identifier associated with information from the mediation module (4) when the service is detected. Said invention can be used for providing services through a multichannel access network or through a plurality of interfaces.

Abstract: The device and method disclosed relate to the field of electronic devices and methods enabling the transposition of any even-order square matrix, the elements of which are given in sequence. The goal is to provide for the transposition of sequences of data representing elementary image blocks, without any duplication of the memory space needed to store an elementary block, in optimizing the two parameters of operating speed and space occupied on silicon. This goal is achieved by a buffer memory divided into two identical storage half-planes, working together with a device for the sequencing of the reading/writing operations, providing simultaneously for a reading operation on one of the storage half-planes and a writing operation on the other half-plane.
