at least one parameter of the universal address of the document describing the multimedia content.
2. The method according to claim 1 , wherein the at least one universal address generator rule specifies the at least one parameter obtained that needs to be taken into account in order to generate the second universal address for the at least one data segment.
3. The method according to claim 1 , wherein the at least one universal address generator rule indicates an order in which at least two parameters that have been obtained need to be taken into account in order to generate the second universal address for the at least one data segment.
4. The method of claim 1 , further comprising:
performing the method by a multimedia content server;
receiving a request by the multimedia content server over the communications network for the document from a client terminal, the request using the universal address of the document; and
sending the document to the client terminal over the communications network.
5. A method comprising:
accessing a multimedia content containing at least one data segment that is accessible via a document describing the multimedia content, said document being accessible through a universal address of the document on a communications network, said access to the at least one data segment taking place via a second universal address of the at least one data segment, said accessing comprising:
obtaining the document describing the multimedia content;
generating at least a first universal address of the at least one data segment;
obtaining at least one parameter of the universal address of the document describing the multimedia content;
reading at least one address generator rule in the document describing the multimedia content; and
generating the second universal address for the at least one data segment as a function of the at least one address generator rule, of the first universal address of the at least one data segment, and of the at least one parameter that has been obtained.
6. The method of claim 5 , wherein:
the method is performed by a client terminal;
the obtaining the document comprises:
sending a request by the client terminal to a multimedia content server over the communications network for the document, the request using the universal address of the document; and
receiving the document from the multimedia content server over the communications network.
7. A multimedia content server comprising:
a non-transitory computer-readable medium comprising instructions stored thereon; and
a processor configured by the instructions to perform acts comprising:
generating a document that is accessible on a communications network through a universal address of the document, said document describing a multimedia content containing at least one data segment that is accessible via at least a first universal address from said document; and
writing at least one universal address generator rule in the document, said at least one universal address generator rule being configured to generate a second universal address for the at least one data segment on the basis of the first universal address and of at least one parameter of the universal address of the document describing the multimedia content.
8. The multimedia content server of claim 7 , wherein the processor is further configured to perform acts comprising:
receiving a request by the multimedia content server over the communications network for the document from a client terminal, the request using the universal address of the document; and
sending the document to the client terminal over the communications network.
9. A terminal suitable for accessing a multimedia content containing at least one data segment that is accessible via a document describing the multimedia content, said document being accessible through a universal address of the document, said access taking place via a second universal address for the at least one data segment, wherein said terminal comprises:
a non-transitory computer-readable medium comprising instructions stored thereon; and
a processor configured by the instructions to perform acts comprising:
obtaining the document describing the multimedia content;
generating at least a first universal address of the at least one data segment;
obtaining at least one parameter of the universal address of the document describing the multimedia content;
reading at least one address generator rule in the document describing the multimedia content; and
generating the second universal address for the at least one data segment as a function of the at least one address generator rule, of the first universal address of the at least one data segment, and of the at least one parameter that has been obtained.
10. The terminal of claim 9 , wherein:
the obtaining the document comprises:
sending a request by the terminal to a multimedia content server over a communications network for the document, the request using the universal address of the document; and
receiving the document from the multimedia content server over the communications network.
11. A non-transitory computer-readable medium comprising a computer program stored thereon and including code instructions for performing a method, when the computer program is executed by a processor, wherein the method comprising:
generating a document accessible through a universal address of the document, said document describing a multimedia content containing at least one data segment that is accessible via a first universal address from said document, wherein the generating comprises:
at least one step of writing at least one universal address generator rule accessible through the universal address of the document, said at least one universal address generator rule being suitable for generating a second universal address for the at least one data segment, by taking into account, for generating said second universal address, both:
the first universal address; and
at least one parameter of the universal address of the document describing the multimedia content.
12. The non-transitory computer-readable medium of claim 11 , wherein the processor is implemented in a multimedia content server and the method further comprises:
receiving a request by the multimedia content server over a communications network for the document from a client terminal, the request using the universal address of document; and
sending the document to the client terminal over the communications network.
13. A non-transitory computer-readable medium comprising a computer program stored thereon and including code instructions for performing a method, when the computer program is executed by a processor, wherein the method comprising:
accessing a multimedia content containing at least one data segment that is accessible via a document describing the multimedia content, said document being accessible through a universal address of the document, said access to the at least one data segment taking place via a second universal address of the at least one data segment, said accessing comprising:
obtaining the document describing the multimedia content;
generating at least a first universal address of the at least one data segment;
obtaining at least one parameter of the universal address of the document describing the multimedia content;
reading at least one address generator rule in the document describing the multimedia content; and
generating the second universal address for the at least one data segment as a function of the at least one address generator rule, of the first universal address of the at least one data segment, and of the at least one parameter that has been obtained.
14. The non-transitory computer-readable medium of claim 13 , wherein:
the processor is implemented in a client terminal; and
