Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently compressing/decompressing a structured document. SOLUTION: A document is associated with at least one structure schema 1 defining a structure of the document and comprising of nested structural components, which represent information elements and nested in mutually. A sequence of executable instructions 5 as to the respective components of the schema is obtained by analysis 11 on the structure schema 1 and compilation 13 of it, and a bit stream format expandable document 10 is decompressed 14'. The sequence of the instructions 5 consists of an instruction, which inserts a control code and an element code or a call for a component instruction, and an instruction controlling execution progress of the sequence based on a control code value. This step includes execution of the sequence of instructions 5 on the bit stream for restoring an original document. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: Le procédé de codage et de décodage d'un chemin s'applique à une structure hiérarchique de document structuré, dans laquelle un chemin est défini par une succession de segments reliant un noeud origine à un noeud destination, chaque noeud représentant un élément d'informations du document, qui est associé à au moins un type d'informations, le procédé comprenant: une phase préalable consistant à associer à chaque noeud de la structure, une liste de couples constitués d'un nom et un type d'élément d'informations, de tous les noeuds susceptibles d'être rattachés directement au noeud, et à associer un code binaire respectif à chaque couple nom - type; et une phase de codage du chemin consistant pour chaque segment du chemin à coder, à déterminer (21, 22) le code binaire de noeud représentant le couple nom - type du noeud destination du segment, et à insérer (23) ce code dans le code du chemin.

Abstract: A method for playing back an item of multimedia content by user devices, the method including steps of: receiving segments of an item of multimedia content by a server, storing the received segments in a buffer memory, transmitting a segment request from a multimedia player of a user device to the server, and transmitting, in response, a requested segment from the server to the multimedia player, if the segment is present in the buffer memory, transmitting a request for synchronization data from the multimedia player to the server, and transmitting, in response to the request, synchronization data from the server to the multimedia player, the data including an identifier of a last segment received, and a datum defining the time of receipt of the last segment by the user's device.

Abstract: The invention relates to a method for transmitting data, comprising the steps of: encoding data to be transmitted in the form of source symbols (S) grouped into a data block (DB), distributing the source symbols of the data block in sub-blocks (SB), calculating for each sub-block a respective repair symbol (R1-R9) by a linear combination of source symbols of the sub-block, and transmitting the data block in a stream of data blocks, by successively transmitting each sub-block of the data block, each sub-block being transmitted by transmitting the source symbols of the sub-block, followed by the repair symbol of the sub-block.
