Claim:
A method of processing a request from a first communication apparatus connected through a communication network to a remote second communication apparatus, the method being implemented in the second apparatus, the method comprising the steps of: receiving the request, wherein the request is for obtaining digital data of a compressed digital signal that comprises header data and a signal body comprising data packets; determining whether or not at least one pointer marker, providing information for calculating the length of the part of the signal body preceding at least one data packet corresponding to the request, is absent in the header data via a test; forming the at least one pointer marker in the compressed digital signal when the determining step determines that the at least one pointer marker providing information for calculating the length of the part of the signal body, is not present in the header data; and processing the request including the step of determining a position, in the body of the compressed digital signal, of the at least one data packet corresponding to the request as a function of the length of the header data and of the at least one pointer marker present in the header data of the compressed digital signal.
