Hi,
I want to point out that
the UVB does not eleminate Macrovision.
Macrovision is still present at the output of the UVB and the macrovision
code will be detected by recording equipment. Macrovision is a copyright
and it is forbidden to replace it like it is done in these illegal copy boxes.
The UVB is designed to make it possible to watch TV on vintage sets.
Attached a screenshot from the oscilloscope.
You can see that Macrovision is present at the output of the UVB.
Kind regards,
Darius
