Do cable or satellite customers need DTV converters?
Despite what you may have heard from someone trying to sell you a new TV, older analog TV sets that are connected to cable, satellite, or other pay services do not require a DTV converter box to receive DTV programs. (See DTV2009, the US Department of Commerce website regarding DTV conversion.) Cable and satellite providers can continue to support analog TVs indefinitely because they do not send programs over-the-air on the old analog channels that are being retired. Precisely how your provider supports your old TV may vary – for example, most set-top-boxes have analog coaxial outputs for this purpose. Note that DTV conversion does NOT require you to upgrade your cable service to High-Definition (HD) TV.
