A Satellite descrambler is an electronic device used to descramble the premium channel signals received through your home satellite dish. The descrambler is often used as an alternative to paying the monthly subscription fee per channel - or group of channels - you are charged by your local provider. These descramblers use technology to break through the encryption applied to the premium and pay-per-view channels.

Most Descrambler sources will carry the common brands such as Jerrold(GI), Pioneer, Scientific Atlanta, Oak, Tocom and Zenith. When your company doesn't carry your brand then you need to find out if they either have in stock or have a source for your uncommon make and model. Usually the source has another outlet or may need to do research on your request.

The universal descrambler utilizes the color burst signal, which is present in all NTSC video signals ( 3.58 MHz ). This signal is the key for regenerating all other timing signals to produce a clear picture. The circuit uses a CD2240 CMOS LSI ( video sync generator ) to produce the vertical and horizontal sync pulses.
