System, computer program product and method for transferring a video stream

A system for transferring a first video stream, the system comprising:

• a sender, the sender being configured to:
• determine a first verification code;
• produce a first produced video stream based on one or several frames of a first source video stream as well as a first piece of information coding for the first verification code in a way so that the first verification code can be unambiguously determined based on the first produced video stream, the producing of the first produced video stream being performed using one or more automatic primary production steps;
• transfer the first produced video stream to a receiver,
• wherein the sender is further configured to:
• down-sample the first source video stream to achieve a first shadow source video stream;
• produce a first shadow produced video stream based on frames of the first shadow source video stream as well as the first piece of information in a way so that the verification code can be unambiguously determined based on the first shadow produced video stream, the producing of the first shadow produced video stream being performed using one or more automatic shadow production steps corresponding to the one or more automatic primary production steps;
• and
• store or distribute the first produced shadow produced video stream.

A non-transitory computer program product for transferring a first source video stream, the computer program product being configured to, when executing on one or several computer processors of a sender, cause the sender to:

• determine a first verification code;
• produce a first produced video stream based on one or several frames of a first source video stream as well as a first piece of information coding for the first verification code in a way so that the first verification code can be unambiguously determined based on the first produced video stream, the producing of the first produced video stream being performed using one or more automatic primary production steps;
• transfer the first produced video stream to a receiver,
• wherein the computer program product is configured to, when executing on one or several computer processors of the sender, further cause the sender to:
• down-sample the first source video stream to achieve a first shadow source video stream;
• produce a first shadow produced video stream based on frames of the first shadow source video stream as well as the first piece of information in a way so that the verification code can be unambiguously determined based on the first shadow produced video stream, the producing of the first shadow produced video stream being performed using one or more automatic shadow production steps corresponding to the one or more automatic primary production steps;
• and
• store or distribute the first produced shadow produced video stream.
