He's just talking about making a universal switchbox.

The cost would probably outweigh the value.

It's got to have he output hardware onboard because it's not
attached to anything else. It's not a "card". More than anything
else it looks like something akin to a macrovision descrambler.

Something that could descramble encrypted HDMI and ATSC would be
quite cool and rather useful and probably very illegal.
