Abstract: Method of transferring digital data between a client device and a server device on a communication network, said method being implemented within said server device and comprising: i) coming from the client device, receiving a request in markup format for the delivery of a digital object or part of a chosen digital object, ii) obtaining in the communication network a representation of the object requested, iii) checking whether the representation of the object thus obtained corresponds to a data compression format of the progressive type, iv) in the event of a positive check, dividing the digital object into a plurality of sub-parts, to each sub-part there being allocated a high priority rank defined according to at least one chosen criterion, and v) sending to the client device a response in markup format comprising the sub-parts of the digital object in binary format and associated priority ranks in markup format.

Abstract: This method of displaying a digital image for creating a multimedia content, the image being coded in multiple resolutions, comprises steps consisting of: determining the number of resolutions present in the coded image, obtaining (E230) the data of the sub-images associated with each of the previously determined resolutions, and displaying (E300) all the sub-images.

Abstract: A method relates to the of determining a data configuration of a digital signal of an image, the signal having undergone at least one spatio-frequential transformation in at least one resolution level. The method includes determining and configuring steps. The determining step determines at least one minimum rate reduction (Dmin) as a proportion of the total data rate of at least one resolution level of the signal, as a function of a quality mode desired for the signal. The configuring step configures the data of the signal in at least one quality layer defined for at least one resolution level of the signal such that the at least one quality layer so defined corresponds to a given visual quality of the signal, the data making up that at least one quality layer being obtained by a reduction (D) of the total rate of the data of the at least one resolution level of the signal which is greater than or equal to the minimum reduction (Dmin).

Abstract: This method of defining qualities for a digital image signal encoded beforehand consists of defining a predetermined number of quality modes each corresponding to at least one decoding parameter of the digital signal, this definition being made on the basis of rate information provided via a graphical interface and quality perception information provided via the visualization of the decoded digital signal.

Abstract: A method of creating a remarkable region in a digital image encoded at a plurality of resolution levels, the encoding data being organized in packets, each packet comprising a field of encoded data, the method including the steps of: selecting at least one remarkable region in at least one resolution level of the image, selecting data packets corresponding to the selected region, constructing an encoded form comprising the selected packets and modified packets, the modified packets corresponding respectively to the packets not selected and comprising an empty data field defining an inaccessible region.

Abstract: A method of transcoding a digital signal encoded according to a first encoding mode into a digital signal encoded according to a second encoding mode, the second encoding mode comprising a bit rate-distortion allocation of the encoded digital signal. The method comprises the steps of obtaining at least a first parameter of encoding the signal according to the first mode, obtaining at least a second parameter from an at least partial encoding of the signal according to the second mode, and selecting a bit rate-distortion allocation mode for the encoding of the signal according to the second mode, as a function of the first and second parameters.

Abstract: A method of recording images composing a panorama in a digital image capture apparatus includes the step of capturing at least one digital image of the panorama, storing the at least one captured image, and inserting information of the at least one captured digital image in a composition descriptor of the panorama including information relating to the different images composing the panorama. The inserted information includes the position of the at least one captured digital image, that position having the coordinates of at least one predefined point of the at least one captured digital image in the panorama and, for at least one region of overlap between at least the captured digital image and at least one adjacent digital image of the panorama, at least one dimension of the region of overlap.

Abstract: A method of creating a remarkable region in a digital image encoded at a plurality of resolution levels, the encoding data being organized in packets, each packet comprising a field of encoded data, comprises the steps of: selecting (S2) at least one remarkable region in at least one resolution level of the image, selecting (S3) data packets corresponding to the selected region, constructing (S3) an encoded form comprising the selected packets and modified packets, the modified packets corresponding respectively to the packets not selected and comprising an empty data field defining an inaccessible region.
