Macrovision works by distorting video signals through the use of automatic gain control chip in a VCR, if the video is being recorded. In order to understand the entire mechanism as to how Macrovision works, you need to have at least some technical know-how of the region free DVDs working methodology. Most of the region free DVD players support certain standards like NTSC, SECAM, or PAL. These standards, which are incorporated in the code free DVD players, could vary from country to country. For instance, countries like USA, Canada, and Japan use the NTSC video standard, while European countries like Italy, Spain, France, or UK usually use PAL standards. The standards are based on the resolution of the video signal. There are certain control codes present in the signals. Macrovision works by adding certain codes to these control codes, which are interpreted through the automatic gain control chip present in a VCR. This entire process scrambles the video signal, in case a video is being recorded. Copies from Macrovision-encoded material will usually be of poor quality, especially when it comes to color or brightness. One is likely to come across picture instability in such cases. It is estimated that around 80% of VCRs have automatic gain control circuitry incorporated in them. What this means is that nearly millions of videocassettes are being provided with copy protection. It must be mentioned here that there are products available in the gray market, which can defeat Macrovision protection. There are also several models of VCRs which ignore Macrovision signals, passing on uncorrupted signals to television sets. There are several models of zone free DVD players which do not have copy guard protection. One can find out by checking out the specifications on a player to find out if it is Macrovision free. A recent development in this area has been the introduction of a new system called Regional Code Enhancing, which is a part of new DVD releases in Region 1. This technology prevents consumers from watching DVDs purchased in North America with their region free DVD players. As with every technology, manufacturers have found ways to circumvent this too, with most players supporting RCE discs. All one needs to do is to change the region using the remote. It is therefore always important to check for the specifications, when one is going to purchase a code free DVD player.
