| UHF | Ultra High Frequency. This is the part of the radio spectrum from 300 to 3000 megahertz, which includes TV channels 14-69. After the DTV transition, UHF TV will be changed to 470 to 698 MHz, which includes channels 14-51. |
| Upconvert | A process by which a digital, high-definition television takes a lower-definition picture and converts it into a higher-definition picture. This may be done by doubling each line as it is drawn on the screen, or by using advanced algorithms to interpolate the data between each lower-resolution line, filling in the missing image. |
