At this point in their evolution, cable systems carry both analog and
digital signals down the same cable. As long as you have an analog
converter/tuner at the user end, the VBI should be passed intact. If cable
goes all digital, like DBS, then use of the VBI will no longer be an option.
However, since before cable can go all digital it must replace all the
customer converters, the cost-effectiveness of Internet delivery will likely
make cable delivery economically unviable long before then.

Subject: Re: Digital Cable
digital cable does not strip all channels,
just those channels using digital broadcast.
if your local carried say switched CNBC, TBS to
digital, then those channels' sideband (where
the DBC and BMI data are) will be stripped and
you will not be able to receive data from those
channels.
Your choice would be to switch over to another
channel that is not affected. For example, in
Toronto Canada one of the local channel is a
data carrier and is a free channel, thus not
affected.
In case all channels your data vendor use are
affected, you will need a new vendor if cable
broadcast is the thing you want.
