Abstract
The application concerns a method for transmitting video data in a data stream and associated metadata, said metadata representing associated video data structure. The method comprises the steps of—determining the structure of the video data, —splitting said structure into chunks in an incremental manner, —transmitting said chunks in the data stream at time intervals before the video data it is related to. The application concerns also a method for transmitting fingerprint information associated with video data into a video data stream. The method comprises the steps of: —determining fingerprint associated with at least one frame of said video data, —inserting at least a message into the video stream comprising said fingerprint information.
