My understand is that this programming information
is piggybacked onto the analog signal of your local
PBS station. It is part of the VBI vertical blanking
interval, so I am thinking this feature will end, but
am not sure.

If I remember correctly, only the information about that particular
channel is in the VBI. this data is still being sent digitally in the
data stream. It's in a standard format that any cable company can
decode. There is a lot of left over room in the new digital stream for
data. A few years ago, we were actually debating what we would put in
that left over bandwidth. I got out of the industry before digital
really took off in our market, so I'm not sure what the outcome was.
