DTV Tuner Cards For PCs to Cost 1/10 the Price of DTVm Tuners!

This according to John Abel, Pres. of Datacast. His company, in particular, makes use of the DTV standard to simulcast IP-standard data as part of the MPEG stream. That means they can put things like Web pages, catalogs and software into the TV signal, letting the computer’s CPU extract this data according to Internet protocol and display it during the telecast or later.
One implication: though PC/TV owners may spend a bit more for their systems, they can use them to decode the DTV signal without buying a separate DTV tuner–and can receive not only higher res pictures, but data enhancements as well.

A guess: it seems likely that non-PC-set-top-box makers (e.g. virtual vcr makers) will find a way to decode this IP data from the MPEG stream too.
