The most common source of LDTV programming is the Internet, where mass distribution of higher resolution files could overwhelm servers and take too long to download. Portable devices such as Apple's video IPod or Sony's PSP use LDTV video, as higher resolution files would be excessive to the needs of their small screens. An upcoming source of SDTV using standard broadcasting techniques are mobile TV services powered by DVB-H or DMB . The Video CD format uses a Progressive LDTV signal (352 × 240 or 288), which is half the vertical resolution of SDTV. A professionally duplicated VHS tape could be considered borderline SDTV , but any attempt to use VHS for production will yield results comparable to LDTV. VHS supports Interlace and High Motion , which are not typical of LDTV signals. SEE ALSO |
