We recently received a notice from Comcast stating you are upgrading your network to an all-digital platform. What is the difference between a Digital Adapter and a Digital Converter and how do we tell which one we need? One TV has a digital converter; the second TV has no converter or adapter.

A digital converter (or "digital cable box", or "digital converter", or "full set-top box") is able to provide all the video services Comcast offers including all channels, program guide, On Demand, PPV, and Music Choice.
A digital adapter (or "digital television adapter", or "digital transport adapter", or DTA) is a limited function device that tunes many digital channels, but does not provide most of the features of a digital converter (ex. no program guide, On Demand, PPV, or Music Choice).
In most markets, if you have a TV package below Digital Starter, DTAs only tune Limited Basic channels. If you have a package above Digital Starter, like Peferred, S&EP, or premium channels, DTAs will only tune Digital Starter channels.
DTAs only have analog coax (channel 3 or 4) outputs. They do not have HDMI, component, composite video, or audio output connectors, and do not provide HD signals. They do not have "favorite" channels.
Comcast charges Additional Outlet fees (about $10/month) for each digital converter after the first one, but does not charge this fee for DTAs.
