Defeating SCMS
(Serial Copy Management System)

I found this on the net sometime ago, and after a lot of requests, decided to setup a local copy also. This is not my work. Refer to the accompanying text from the designer. I only merged the GIF picture showing the PCB layout from the ones in the GIF archive. Also, I added a list of components used.

With a bit of work, any electronic geek can figure out how things work here. Basically, this board features:

• high performance jitter correction;
• removes SCMS copy protection;
• multiple inputs/outputs, both optical and coaxial;

Contrary to earlier statements, the SCMS killer does seem to remove track marks in most cases.

I disclaim any responsibility from you using anything presented here. Please read the designer's notes and disclaimers also.
Here are the appropriate files:

• Some notes by the designer (which is not me).
• ZIP archive with PCB layout in GIF format.
• ZIP archive with PCB layout in PS format.
• ZIP archive with PCB layout in HPGL format.
• GIF picture showing the PCB layout.
• Text file containing the bill of components.

Have fun, Leon Woestenberg.
