James M Barton, Howard Look: Analog video tagging and encoding system. TiVo, Michael A Glenn, Kirk Wong, April 10, 2001: US06215526 (197 worldwide citation)

An analog video tagging and encoding system is disclosed. The invention inserts an analog tag frame into the analog video stream such that the luminance (Y) values are made to approach zero, i.e., black, allowing a potential tag frame to be quickly identified. Tag information is then encoded as a st ...
