Moreover, with DRC, each field is processed separately, so there's never
a need to compensate for motion between two fields. And while the dou-

What it all means
Digital Reality Creation circuitry greatly enhances the television viewing
experience. Now you can sit up close to the screen, immersing yourself
in the magic of home entertainment – and still not be bothered by visible
scanning lines. Pictures appear denser and more seamless. And in the
coming world of Digital TV (DTV) broadcasting, televisions with Digital
Realty Creation circuitry will narrow the perceived gap among NTSC ana-
log sources, standard definition digital and full High Definition digital video.
