Yes, this is a concern. But you could still do PIP with other
sources, including an NTSC tuner. This will take place in the image
processing portion of the box. And I guess you could do PIP with
different PIDs within a single ATSC transport stream.
I wonder if there are any portions of the "tuner" that can be shared
with the demod/equalizer chips?
