My copy has the UPC added as a sticker.

This demonstration disc discusses the History of Dolby laboratories, the differences between Dolby B, C and S types of Noise Reduction, a demonstration and in depth walkthrough of Pro Logic Surround decoding, HX Pro and Time Link Digital Delay.

The catalogue number is printed on the disc only, and not the sleeve.

Includes an insert with info on contacting Dolby and Time Delay graphs.

This title starts with the following (rolling) on screen text:

Program Notice  
The following program contains 
information describing the 
operating principles of 
technologies from Dolby Laboratories.


This educational material is 
intended for retail specialists, 
product trainers, and 
interested consumers.

Thank you.

From the rear cover:

This is not a "demo" disc, but an info disc. With computer graphics and concise narration, it explains just how the technologies from Dolby Laboratories deliver real benefits in sound reproduction.
