Abstract:
1. A 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, said method comprising the following steps performed in the following successive order: i) receiving a request in mark-up format for the delivery of a digital object, the request coming from the client device, ii) obtaining in the communication network an encoded representation of the digital object requested, iii) checking whether the encoded representation of the digital object corresponds to a progressive data compression format, iv) in response to checking, dividing the encoded representation of the digital object into a plurality of sub-parts, each of the sub-parts being in the encoded form of the encoded representation, and, once the division is made, assigning to each of the encoded sub-parts a priority rank defined according to at least one predetermined criterion, the priority rank indicating to the client device whether a processing of the encoded sub-part is mandatory or optional, v) forming a response in mark-up format for transmitting the encoded sub-parts in binary format as attachments, the step of forming the response comprising adding (a) mark-up elements indicative of the presence of attachments and (b) corresponding mark-up attributes representative of the priority ranks associated with encoded sub-parts of the digital object in binary format comprised in the corresponding attachments, and vi) sending the formed response in mark-up format to the client device from the server device.
