A/335 “Video Watermark Emission”
The video watermark technology described in this document provides the capability to robustly embed ancillary data in the transmitted pixels of a video signal. It is intended to provide a data path for its ancillary data payload that can readily survive changes in video compression data rate, transcoding to other video compression codecs, and delivery over legacy consumer HDMI interfaces. It is not intended to be a tamper-resistant or indelible watermark, and it may be deliberately obliterated by an intermediary. Emission by a broadcaster of the video watermark is optional.
