Abstract
Methods and systems are disclosed for distributing video sequences in a coded stream. The methods and systems include analyzing an original coded stream, generating at least one modified coded sub-frame, generating, based upon the analysis, a modified stream and a second stream by replacing an original coded sub-frame by the modified coded sub-frame, so that the modification from the original coded sub-frame results in a visually altered video sequence, transmitting the first and the second generated streams, and reconstructing the original stream using the modified coded sub-frame contained in the second stream.
