Digital processing disruption systems

A method executable by a device to modify an analog video signal and thereby impair analog to digital conversion of the signal, the signal comprising a plurality of horizontal synchronization pulses, each adjacent a respective back porch, the method comprising:

• receiving disruption components from a remote source;
• receiving the analog video signal by the device;
• modifying, by the device, a region of the analog video signal following at least one of the horizontal synchronization pulses from its original form, wherein the modifying is configurable to be based upon the disruption components received from the remote source;
• and
• outputting the modified video signal by the device, wherein the modified video signal is such that the modified video signal interferes with the operation of an analog to digital video conversion system to such an extent that the output of the analog to digital video conversion system has a reduced quality on playback in comparison to the original analog video signal.

An apparatus to process an analog video signal that comprises a plurality of horizontal synchronization pulses, the apparatus comprising:

• an input configured to receive the analog video signal for modification;
• an analog-to-digital conversion circuit;
• and
• circuitry configured to modify at least a region of the signal following at least one of the horizontal synchronization pulses from its original form to have a different amplitude based upon disruption components received from a remote source, and to output the modified video signal to the analog-to-digital conversion circuit, wherein the modified video signal is such that the modified video signal interferes with the operation of the analog to digital video conversion circuit to such an extent that the output of the analog-to-digital circuit has a reduced quality on playback in comparison to the original analog video signal.
