Upconvert - The process which increases the number of pixels or frame rate used to represent an image by creating new pixels at closer spacing. For instance SDTV video having 720 x 480 pixels may be upconverted to 1280 x 720 pixels for use as HDTV. The upconversion process does not increase the resolution of image.
PPI (Pixels Per Inch) - Often used interchangeably with DPI, PPI refers to the number of pixels per inch in an image.
Megabyte - 1000 kilobytes
Pixel - The smallest unit of color on a computer screen. High resolution devices have more pixels per square inch.
Automatic Advanced Film Enhancement - When film is transferred to video, the process can combine information from two very different film frames into a single mixed video frame, causing motion blurring and jittery sequences. Part of Hitachi's VirtualHDT digital video processor, 3:2 Pulldown Correction ensures that new video frames are only constructed from discrete film frames for a smooth, seamless picture.
COFDM modulation technique. This technical standard has been used in Europe and other places for digital TV. 8VSB is used in the U.S.
Viewing Screen, New VVLL - The new VVLL (variable vertical lenticular lens) viewing screen on projection TVs transfers more light to the outer edges of the picture to improve the overall brightness uniformity, resulting in a more natural looking image.
