    Hi everyone, has anyone bought a vice1000 or can they sus it out on that auction site. It replaces the Vertical blanking area with its own code so dose that get rid macrovision as that is in the VBI. If it dose then whoever is making this might have got round the laws as this is legal.

    Hope you can help

    The vertical blanking interval (VBI) or vertical interval for short is an interval in a television or VDU signal that temporarily suspends transmission of the signal for the electron gun to move back up to the first line of the television screen to trace the next screen field.

    The VBI is necessary mostly because of the inductive inertia of the magnetic coils which deflect the electron beam vertically: the magnetic field cannot change instantly. For horizontal deflection, there is also a gap between successive lines, to allow the beam to return from right to left, called the horizontal retrace or the horizontal blanking interval.

    The vertical blanking interval can be used to carry data, since anything sent during the VBI would naturally not be displayed; various test signals, time code, closed captioning, teletext, CGMS-A copy-protection indicators, and various data encoded by the XDS protocol (e.g., the content ratings for V-chip use) and other digital data can be sent during this time period.

    Most consumer VCRs use the known black level during the vertical blanking interval to set their recording levels. The Macrovision copy protection scheme uses pulses in the VBI on videotapes to disrupt recording.

    I dont believe it can/or will remove the Macrovision protection
    that it already present in the VBI, not positive though.

    Hi Guys, I bought one of these and it works a treat. It works 100% to remove copy protection..

    It puts its own information in the macrovision area as you play your film through it, so essentially it overwrites the existing information and all traces of cgms and macrovision are removed from the copy.
