An interactive or electronic programming guide is provided, wherein a receiving device such as a DVD or Blu-Ray player, PVR, recorder, set top box, etc., receives data or video signals as well as a trigger, flag or bit pattern signal. A processing and or encoding circuit provides programming, enabling, or disabling of a content control signal in response to the trigger, flag, or bit pattern signal and the content control signal is combined with the video signal to provide a content controlled video signal which provides resistance to a circumvention device (e.g., a “black box”). |
