1. A method of processing a digital signal identified by a unique identifier in a distributed communication network composed of several communication apparatuses, comprising steps of:
- storing at least a part of data constituting the identified digital signal in a local storage located in one of the communication apparatus; and
managing two descriptors related to the identifier within the local storage, the two descriptors including a first descriptor, which provides a description representing a structure and an organization of the data constituting the identified digital signal, and a second descriptor, which is dependent on the first descriptor and representative of the part of the data stored in the local storage,wherein the data constituting the identified digital signal is in a multiresolution format and wherein the second descriptor has a hierarchical structure related to the multiresolution format.
