Digital Copy Control
A beginners guide to copy control CD, DVD, Audio & Video
Copy control is the ability to control if a user may make copies of something. This may be print copies or computer copies or both.
Copy control may be difficult to achieve. In the article on copy prevention we noted that stopping people from copying computer files is very difficult indeed, if not almost impossible, and copy control is very similar.
At one level of copy control, it is impossible to stop someone from sitting in front of a computer screen with a camera and taking a picture of every screen they see (just as you cannot stop someone from putting a tape recorder in front of the loudspeakers of a hi-fi unit and recording what is being played back). Sometimes the laws of physics get in the way of the desires of companies to be able to protect their IPR.
At another level, it can be made very difficult or very inconvenient for someone to be able to make a copy of something. After all, it isn’t everyone who has a camera capable of taking good quality pictures from a high resolution screen in order to produce an acceptable quality copy, just as it isn’t everyone who has a studio quality recording system to make a decent copy of their favorite CD track. Hey, it’s so much easier if you can just do it on the computer because the copies are always perfect!
So getting some ability to impose copy control may not be so simple. You may, as the article on copy-prevention noted, make sure that only the authorized user can make copies, but if they can make copies that someone else can then use, you are back to square one.
So, as the video industry finally figured out, if you have a system where the quality of the copy is acceptable, but not better, and certainly not top quality, then you might have a system that works for both suppliers and customers. Because customers can have printed reference copies that are alright, but nothing better, because the main on-screen copy is better quality and gives them the real result.
So copy control is about making sure that where you do authorize copies to be made of your intellectual property, you have digital rights management tools in place that enable you to make sure that the quality of copies is not sufficiently good that the copies can undermine the value of your work.
