SPECIFIC SERVICE INSTRUCTIONS
2.1 FEATURES
2.1.1 FUNCTION / CIRCUITS
• DIST (Digital Image Scaling Technology) employs an interpolation
method that doubles the scanning lines to realize 1250-line flickerfree picture making it especially suitable for reproducing highresolution pictures even on large-screen displays.
• New chassis design enable use of an interactive on screen
control.
• The TELETEXT SYSTEM has a built-in FASTEXT (UK
system), TOP (German system) and WST (world standard
system) system.
• Because this TV unit corresponds to multiplex broadcast,
users can enjoy music programs and sporting events with live
realism. In addition, BILINGUAL programs can be heard in
their original language.
• Users can make VCR dubbing of picture and sound by
controlling the AV selector to select an optional source at the
EXT-2 output shown in figure.
