The digitalized terrestrial broadcasting system provides another major benefit: stable reception onboard vehicles and trains in motion. With conventional analog broadcasts, high-speed movement of receiving equipment and factors that affect radio wave interference, including topography, buildings, and weather, can significantly affect signal strength and quality. Poor signal reception results in image disturbances. Digital broadcasts, on the other hand, use special digital processing to restore received signals even when data fragments are dropped, thereby maintaining image and audio quality under less than ideal reception conditions.

Car-mounted digitalized terrestrial TV tuners, which take advantage of this unique feature, are now under development. In 2003, experiments performed in Tokyo by NHK Science & Technical Research Laboratories confirmed that digitalized terrestrial broadcasts would provide clearer, more stable reception of High-Vision images from moving vehicles than current analog broadcasts. Clear image reception can currently be maintained up to speeds of about 80 km/h; NHK's Mr. Ikezawa believes future technical developments will allow equivalent image reception at speeds exceeding 100 km/h.

Under yet another plan, part of the bandwidth allocated to digitalized terrestrial broadcasts will be used to provide broadcasting services for dedicated mobile terminals and third-generation (3G) mobile phones. By compressing data at high rates, these services will transmit large data volumes to mobile equipment, which generally feature low communication rates, limited battery life, and small screen size. Several manufacturers have already announced prototypes of digitalized terrestrial-broadcast-ready cellular phones. The advent of such services will allow people to enjoy sports broadcasts and TV programs in real-time, anytime, anywhere outdoors or in moving vehicles.
