What is a Handheld Digital TV?
A handheld digital TV is a portable device which allows users to receive digital broadcasts. This can offer users many more channels than a portable analog TV, usually with better picture quality. However, using such a device on the move can mean much more retuning to get a signal than with an analog set. The decoding necessary to display a digital signal can mean such devices use more power than older handheld TVs. The handheld digital TV became much more prominent in June 2009 when the United States switched off most of its analog TV signals. An estimated eight million people owned a handheld analog TV at this time. However, these devices became largely useless, as it was impractical to add a converter box in the same way as was done with full-size TV sets.
