Patent ID: 8280049

Claim:
A method of providing a video copy protection signal for a video signal by causing a copy protection signal circumvention device to fail in removing the video copy protection signal at its output, wherein a vertical sync signal includes a pre-equalizing pulse interval, a vertical sync pulse interval and a post-equalizing pulse interval, wherein the circumvention device does remove a standard video copy protection signal which includes pseudo sync pulses starting at least two video lines after the post-equalizing pulse interval of the vertical sync signal, and wherein the video copy protection signal is coupled to an input of the circumvention device, comprising: inserting or adding via a circuit in at least one TV line in the video signal one or more pseudo sync pulse or one or more pseudo sync pulse/AGC pulse pair signal less than two TV lines after the post-equalizing pulse interval of the vertical sync signal; and providing a copy protected video signal as the result of the circumvention device's failure to remove the video copy protection signal coupled to its input, wherein the output of the circumvention device provides the copy protected video signal.
