Abstract: A data communication method is proposed which comprises: configuring a first application interface coupled operationally to a data storage management interface, for defining a correspondence between an application data message and a memory addressing zone managed by the data storage management interface; generating a data storage command on the basis of the memory addressing zone and the application data message; and issuing, by the first application interface, the data storage command message to the data storage management interface for sending the application data message to a second application interface, through the data storage management interface.

Abstract: A CABAC-type encoding device for encoding an initial flow of binary digital information for generating an output flow for forming video images after decoding, includes: elements for analyzing successive sequences of bits of the initial binary flow, bit-by-bit, and for deducing, for each bit, an interval representing the occurrence probability associated with the bit, the interval being defined by the size thereof and the lower boundary thereof; elements for analyzing the interval and ensuring a renormalization thereof. The elements for ensuring the renormalization include: a reference table containing, for each possible value of the lower boundary and the size, sequences of bits to be inserted into the output flow, and the number of unknown bits waiting to be inserted for this specific renormalization step; and elements for determining the address of the data, in this reference table.

Abstract: A method for delivering multimedia data to a user device of a multimedia data delivery system is proposed, which includes, at a server device of the multimedia data delivery system, receiving, from the user device, a query message requesting service list data. The query message includes a parameter for querying custom service list data in relation to a user of the user device, and upon receiving the query message, generating a response message for transmission to the user device which includes a list of multimedia services customized for the user based on the parameter.
