System, datorprogram och metod för överföring av videoström

Patentradars sammanfattning

This patent describes a framework for authenticating and verifying the integrity of transferred video streams by generating a verification code (VC1) derived from the original video content and/or a shared secret value. VC1 is translated into visually identifiable graphical objects that are embedded into video frames, producing an intermediate stream from which piece-of-information (POI1) is extracted and correlated with VC1. A final video stream (PVS3) carrying the embedded verification data is transmitted to the receiver, which reconstructs and validates VC1 to confirm authenticity. The scheme is explicitly engineered to remain robust against downsampling, lossy compression, and quality degradation that typically occur in video pipelines.
