Abstract

TITRE DE L’INVENTION : PROCÉDÉ DE FOURNITURE D’UN CONTENU COMPORTANT AU MOINS UNE IMAGE, FORMAT DE FICHIER Le procédé (600) de fourniture d’un fichier informatique, comporte :- une étape (605) d’hébergement, dans une mémoire informatique, d’un fichier informatique unitaire comportant, dans une trame unique :- au moins deux éléments de contenu, chaque élément de contenu étant d’un type d’élément défini,- un entête, comportant une information représentative d’un nombre d’éléments du fichier et- une table, comportant, pour chaque élément représentatif d’un contenu distinct, un descripteur composé d’une valeur correspondant à la taille de l’élément, d’une valeur de type d’élément associée à cet élément et d’une valeur d’index correspondant à une position dans un tableau de sections du type de l’élément,- une étape (610) d’émission, par un équipement informatique, d’une requête de réception d’un fichier informatique temporaire,- une étape (615) de génération, d’un fichier informatique temporaire à partir du fichier permanent, ladite étape de génération comportant :- une étape (616) de lecture, partielle ou non, de la table du fichier, de la table pour isoler le descripteur d’au moins un élément du type requis associé à l’adresse dudit élément,- une étape (617) de duplication sélective de chaque dit élément, en fonction d’au moins une adresse calculée, et de son descripteur, dans le fichier temporaire,- une étape (618) de création d’une information d’en-tête du fichier temporaire en fonction des données dupliquées et- une étape (620) de fourniture du fichier temporaire à l’équipement informatique émetteur de la requête de réception. Figure pour l'abrégé : Figure 9TITLE OF THE INVENTION: METHOD FOR SUPPLYING CONTENT COMPRISING AT LEAST ONE IMAGE, FILE FORMAT The method (600) for supplying a computer file comprises:- a step (605) of hosting, in a memory computer, of a unit computer file comprising, in a single frame:- at least two content elements, each content element being of a defined type of element,- a header, comprising information representing a number of elements of the file and- a table, comprising, for each element representing a distinct content, a descriptor composed of a value corresponding to the size of the element, of an element type value associated with this element and an index value corresponding to a position in a table of sections of the type of the element,- a step (610) of transmission, by a computer equipment, of a request to receive a computer file temporary,- a step (615) for generating a temporary computer file from the permanent file, said generation step comprising:- a step (616) for reading, partially or not, the table of the file, the table to isolate the descriptor of at least one element of the required type associated with the address of said element,- a step (617) of selective duplication of each said element, as a function of at least one calculated address, and of its descriptor , in the temporary file, - a step (618) of creating temporary file header information based on the duplicated data and - a step (620) of supplying the temporary file to the computer equipment sending the the receive request.
