Abstract:
1. A method implemented by a processor of altering a control command in a copy, record or content control system, wherein the copy, record, or content control system receives a program video signal including an analog copy protection signal, wherein the analog copy protection signal includes at least one pseudo sync pulse and or positive going pulse in a horizontal blanking interval, and or a color stripe burst signal, and wherein one or more portion of the analog copy protection signal provides a content control signal, the method comprising: providing via a circuit the program video signal with a content control signal indicative of a control command for performing a subsequent intended function, wherein the program video signal is playable on a monitor; and altering via a modifying circuit at least a portion of the program video signal and/or the analog copy protection signal to cause a correspondingly altered control command to be subsequently generated by the content control system, wherein the modifying circuit selectively repositions or redistributes at least a portion of the content control signal.
