When analogue signals are no longer available will my analogue television become obsolete? No. Consumers will be able to continue watching analogue broadcasts, cable, videocassettes, DVD and satellite as well as watch the new HDTV broadcasts using a DTV-to-NTSC set-top box. The set-top box will deliver many of the benefits of DTV broadcasting including HDTV programming, superior picture and clear sound. However, an analogue television cannot display the full quality of High-Definition images or sound.
