Abstract

A method is provided for processing at least one multimedia stream pertaining to a real event, which is being acquired or has been acquired by a communications terminal. The method includes sub-dividing the stream into a plurality of consecutive sequences, on the basis of at least one distribution characteristic associated with each of said sequences. The step of sub-dividing is activated by distribution of the first stream by the communications terminal.

Claims

1. A method for processing at least one multimedia stream pertaining to a real event, which is being acquired or has been acquired by a communications terminal, denoted as a first stream, wherein said method comprises the following steps:

sub-dividing said first stream into a plurality of consecutive sequences, on the basis of at least one distribution characteristic associated with each of said sequences, said sub-dividing being activated by distribution of said first stream by said communications terminal and

replacement, in said first stream, of at least one part of a first sequence associated with a predetermined distribution characteristic by at least one part of a second sequence, identified from at least one distribution characteristic, of at least one second multimedia stream pertaining to said event, said second stream being distinct from said first stream, said part of said second sequence being of a same time frame as said part of said first sequence, said second part being selected according to said predetermined distribution characteristic associated with said first sequence, generating an optimized multimedia stream.

2. The method for processing according to claim 1, wherein said distribution characteristic associated with a sequence is defined on the basis of elements of information belonging to the group consisting of:

a shooting parameter;

a parameter of confidentiality depending on a recognition of objects in the sequence;

a geolocation of said terminal and/or a place of occurrence of said event;

an order of association of an operator.

3. The method for processing according to claim 1, wherein said method further comprises a preliminary step of identifying said event delivering a piece of information for identifying said event comprising at least one temporal and geographical demarcation of said event.

4. The method for processing according to claim 1, wherein said method comprises a preliminary step of taking account of a registration of said terminal.

5. The method for processing according to claim 4, wherein said registration of said terminal comprises at least one piece of information for identifying an event.

6. The method for processing according to claim 1, wherein said method comprises a step of temporal synchronization of said first stream with a reference time base.

7. The method for processing according to claim 1, wherein said step of replacement is implemented periodically on said first stream.

8. The method for processing according to claim 1, wherein said step of replacement comprises a step of validating the replacement of said first part by said second part according to a comparison of the content of said parts of sequences.

9. The method for processing according to claim 1, wherein said step of replacement comprises a step of homogenizing an encoding of said part of said second sequence with an encoding of said part of said first sequence.

10. The method for processing according to claim 1, wherein said method further comprises a step of distributing said optimized multimedia stream to at least one recipient terminal.

11. A processing server for processing a multimedia stream pertaining to a real event, denoted as a first stream, wherein said server comprises:

means for sub-dividing said first multimedia stream distributed by a communications terminal and received by said processing server, said first stream being sub-divided into a plurality of consecutive sequences, on the basis of at least one distribution characteristic, associated with each of said sequences; and

means for replacing, in said first received stream, at least a part of a first sequence associated with a predetermined distribution characteristic by at least one part of a second sequence, of a second received stream, said second multimedia stream pertaining to said event and being distinct from said first stream, having a same temporal overlap as said part of said first sequence, said part of said second sequence being selected according to said predetermined distribution characteristic, generating an optimized multimedia stream.

12. A non-transitory memory storing a program which, when executed by a computer or a processor, causes the computer or the processor to carry out a method for processing at least one multimedia stream pertaining to a real event, which is being acquired or has been acquired by a communications terminal, denoted as a first stream, wherein said method comprises the following steps:

sub-dividing said first stream into a plurality of consecutive sequences, on the basis of at least one distribution characteristic associated with each of said sequences, said sub-dividing being activated by a distribution of said first stream by said communications terminal; and

replacement, in said first stream, of at least one part of a first sequence associated with a predetermined distribution characteristic by at least one part of a second sequence, identified from at least one distribution characteristic, of at least one second multimedia stream pertaining to said event, said second stream being distinct from said first stream, said part of said second sequence being of a same time frame as said part of said first sequence, said second part being selected according to said predetermined distribution characteristic associated with said first sequence, generating an optimized multimedia stream.
