The analog switch-off ruling, which so far has met with little opposition from consumers or manufacturers, would render all non-digital televisions obsolete on the switch-off date, unless connected to an external off-the-air tuner, analog or digital cable, or a satellite system. An external converter box (an [[ATSC tuner]]) can be added to non-digital televisions to lengthen their useful lifespan. Several of these devices have already been shown, and while few are currently available, American industry and government statements predict that low-cost units will be available in January 2008.<ref>{{cite web |url=http://www.nytimes.com/2007/06/07/technology/07digital.html?ex=1338955200&en=1dfe5b2fbfdadf20&ei=5124&partner=digg&exprod=digg|title=Converters Signal a New Era for TVs}}</ref>

Some existing analog equipment will be less functional with the use of a converter box. For example, television remote controls will no longer be effective at changing channels, because that function will instead be handled by the converter box, although this could be easily fixed by designing the box to be able to be programmed to respond to the channel buttons on the remote control. Similarly, video recorders for analog signals (including both tape-based [[VCR]]s and hard-drive-based [[Digital video recorder|DVR]]s) will not be able to select channels, limiting their ability to automatically record programs via a timer or based on downloaded program information.
