Embedding video watermarks without visible impairments

A system comprising:

• one or more processors;
• and
• a non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations including:
• detecting, in a video frame, a watermark based on pixel values of pixels of a first set of pixels, the first set of pixels corresponding to a first region of the video frame, wherein the detected watermark comprises data that was encoded based on modifications to luminance and/or chrominance values of pixels;
• identifying, within the first set of pixels, one or more subsets of pixels that correspond to a first pixel value and one or more subsets of pixels that correspond to a second pixel value;
• assigning a first symbol to the one or more subsets of pixels that correspond to the first pixel value and a second symbol to the one or more subsets of pixels that correspond to the second pixel value;
• and
• generating, based on the first symbol and the second symbol, a first sequence of symbols corresponding to the data.
