Definitions

  • the present invention relates to a subliminal message system and, more particularly, to a method and apparatus for processing subliminal audio and video messages for television signals.
  • the first approach involves providing dedicated preprogrammed tapes with the subliminal messaging edited into the tape itself. This approach allows the use of non-real-time subliminal messages. However, this approach fails to provide a method of changing the messages without having to buy additional tapes. Moreover, by its nature, this approach precludes the viewing of any real-time television programs while the tape is being used.
  • the second approach involves providing an antenna switch apparatus that switches one of two signals (either the RF TV signal or an externally generated RF "subliminal” message) onto the television receiver input. While this second approach allows the use of real-time subliminal messages, the affect is a degradation of the Signal to Noise Ratio (SNR) of the actual television signal. In other words, the input RF signal is degraded by the RF switching mechanism used to interject the occasional message.
  • SNR Signal to Noise Ratio
  • This second approach must use externally generated timing and synchronization signals for horizontal and vertical retrace operations. These signals provide phase shifted information to the television's control circuitry, resulting in distortion of the image displayed on the screen. Furthermore, this second approach does not allow for consistent placement of the subliminal video message on the screen, does not allow for audio information to be added as a subliminal influence, and cannot produce subliminal messaging while viewing prerecorded tapes. There are several earlier patents that attempt to produce subliminal messaging, many of them dealing only with motion pictures or prerecorded tapes. Only patents relating to the introduction of real-time subliminal messages onto the screen and/or through the speakers of the television set are in any way comparable to the present system.
  • U.S. Patent No. 4,616,261 to Crawford, et al (issued October 7, 1986) .
  • a dedicated home computer is used as the source of the subliminal messaging.
  • the computer is programmed to produce subliminal video messages as well as horizontal and vertical synchronization pulses that are then up- converted in frequency with an RF modulator.
  • This RF signal is then introduced into one leg of an RF switch, with the other leg of the switch being the actual RF television signal.
  • the television signal is the signal normally allowed to pass through the switch and onto the receiver of the television.
  • the computer generated subliminal message is switched in and the normal television signal is switched out in order to illuminate the screen with the "subliminal" message.
  • This approach attempts to provide the subliminal messaging, but falls short because of several reasons, for example:
  • the normal television signal is cut out during the period of time that the subliminal message is being displayed. The effect of this can be very observable, thus negating any "subliminal" affect generated by the message.
  • the vertical scan rate for NTSC television is 60 frames a second. Even if the computer and switch were fast enough (which they're not) to introduce the message for the shortest possible duration (1/60 of a second) , the blanking of the normal television screen image would produce a very noticeable flicker on the screen. 2.
  • the entire television image is replaced with a subliminal message enclosed in a white or black background, rather than the more "subliminal" approach of introducing the subliminal message on top of the normal image at a viewer selectable intensity.
  • the horizontal and vertical sync pulses generated by the computer are not synchronized with the equivalent signals provided by the internal circuitry of the television's receiver. This leads to timing and phase distortion that can lead to "tearing" of the image produced on the screen as well as to lost chrominance information (especially severe as the repetition rate of the introduction of the subliminal message is increased) that will adversely affect the displayed color effects.
  • embodiments of the present system utilize only the horizontal and vertical sync pulses generated by the receiver of the television itself, so there is no possibility of corruption.
  • the apparatus produces only video subliminal messages, rather than both video and audio subliminal messages. 5. The apparatus cannot subliminally influence prerecorded video tapes.
  • a television signal is received by a video cassette recorder (VCR) .

  • the VCR includes a demodulator which operates to separate the video baseband signal and the audio baseband signal from the television signal.
  • the video baseband signal is supplied to a video circuit and the audio baseband is supplied to an audio circuit.
  • Subliminal message information is pre-recorded on a floppy disk.
  • Information is read from the floppy disk via a floppy disk drive and a disk controller command circuit.
  • the information read from the floppy disk is supplied to the video and audio circuits.
  • information corresponding to the video portion of a subliminal message is added to the video baseband signal. Prior to such adding, the intensity of the information signals corresponding to the video subliminal message is adjusted.
  • information signals corresponding to an audio subliminal message are added to the audio baseband signal.
  • the intensity of the information signals corresponding to the audio subliminal message are adjusted prior to being added to the audio baseband signal.

  • the normal television signal is not interfered with, but only added to in order to "overwrite" the original signal for a small segment or pixel of the display.
  • the arrangement of these l's or O's determines the subliminal image that overwrites the normal television image.
  • the intensity of each added 1 is determined by the variable resistor 37 shown prior to the adder 36.

  • the subliminal video message can be added to the raw television message with varying repetition rates.
  • the vertical scan rate (the rate at which new complete video images are updated on the screen) of NTSC television is 60 cycles a second. That implies that the fastest a new image can be shown is 1/60 of a second. Therefore, the fastest one can interject a subliminal signal onto the television screen is also at that 1/60 of a second rate. That rate directly influences the persistence of the Cathode Ray Tube (CRT) , or television screen and therefore determines the intensity level that the added subliminal message should not surpass in order to remain unconscious to the casual viewer.

  • the repetition rate (or frequency) is user selectable via a repetition switch 42 (e.g., a multiposition user selectable switch).

This is accomplished by counting the horizontal sync pulses with a horizontal sync counter 39. At this point, the subliminal video is added to the original television signal until another horizontal sync counter 40 determines that the message is complete, shutting off the subliminal contribution to the image. Following this, the cycle begins anew by counting the selectable number of images, etc.

As shown in Fig. 5, the location switch 43 is arranged to selectively initialize the horizontal sync pulse counter 39. Since the horizontal sync pulse counter 39 determines the location of each subliminal message added to the television signal, by changing the switch setting of the location switch 43, one can thereby change the location of the added subliminal message image.

Abstract

Dans les modes illustrés de réalisation, un signal de télévision (en 10) est reçu par un magnétoscope à cassette (VCR) (11). Le signal de bande de base vidéo est envoyé à un circuit vidéo et le signal de bande de base audio est envoyé à un circuit audio. Les informations de message subliminal sont préenregistrées sur un disque souple (15). Les informations sont lues du disque souple par l'intermédiaire d'une unité à disque et d'un circuit de commande de disque (20). Les informations lues du disque souple sont envoyées aux circuits vidéo et audio (21, 22). Dans le circuit vidéo, les informations correspondant à la partie vidéo d'un message subliminal sont ajoutées au signal de bande de base vidéo. Avant cette addition, l'intensité des signaux d'information correspondant au message subliminal vidéo est ajustée. Dans le circuit audio, les signaux d'information correspondant à un message subliminal audio sont ajoutés au signal de bande de base audio. L'intensité des signaux d'information correspondant au message subliminal audio est ajustée (en 29) avant de les ajouter (en 30) au signal de bande de base audio. Les signaux vidéo et audio obtenus sont ensuite modulés (en 23) pour produire un signal de télévision.
