-=IDENTIFY HOW YOUR CABLE HAS BEEN SCRAMBLED=-

You can't win the war if you don't know your enemy, right. Well then how do you expect to descramble your cable without knowing how it's scrambled. Just compare the images below to your scrambled stations to find out how the channels are scrambled.

Sync Suppression

If you can't see this, then this page is worthless to you!
Sync Suppression is easily identified by the "wavy bar" that 
wiggles through the picture. This bar is actually the horizontal 
blanking interval. 

A close look at the bar, will show 4 bands 
(white,black,colored,white). The black band is the sync (or lack 
of it) and the colored one is the color burst. This information is 
normally hidden behind the right edge of the picture tube. 

 

Video Inversion

If you can't see this, then this page is worthless to you!
Video Inversion involves more than just inverting all the video 
information. The active video (the stuff that lies between the two 
sync intervals) is all that gets inverted. The sync and color 
information remain at their proper polarity. This causes the 
color burst to be phase shifted 180 degrees, in respect to the 
chroma. The end result is a negative image (dark = light) with a 
color shift (ie: yellow = blue). 

This method is usually coupled with sync suppression. 

 

SSAVI Suppression

If you can't see this, then this page is worthless to you!
The SSAVI system is easily identified by the "dotted" line that 
appears near the top of the screen. These "dots" are actually the 
authorization data contained on lines 10-13 of the vertical 
interval.
