Abstract
Et widescreen-fjernsynssignal samples ned en høyere samplingstakt for å passe inn hele signalinformasjonen i den någjeldende, aktive videolinjetid på 52,5 >is. Et utvelgingssignal innlemmes også sammen med widescreen-billedsignalet, slik at ik.i^e-widescreen-f jernsynsmot- takere tillates å fremvise en sammen- hengende del av widescreen-bildet uten geometrisk forvrengning. Widescreen- fjernsynssignalet overføres enten i MAC- format eller widescreen-NTSC-format, og mottas av en dekoder. Dekoderen tillater hele widescreen-bildet å fremvises på en widescreen-mottaker, og gjør bruk av ut- velgingssignalet til å fremvise den utvalgte del av bildet på en normal mot- taker uten geometrisk forvrengning. I en annen utførelse tillater en dekoder fjernsynssignaler med det normale side- forhold å fretnvises på mottakere som har widescreen-sideforhold, uten geometrisk forvrengning.A widescreen television signal is sampled down a higher sampling rate to fit the entire signal information into the current active video line time of 52.5> ice. A selection signal is also incorporated with the widescreen image signal, so that non-widescreen television receivers are allowed to display a coherent portion of the widescreen image without geometric distortion. The widescreen television signal is transmitted either in MAC format or widescreen NTSC format and received by a decoder. The decoder allows the entire widescreen image to be displayed on a widescreen receiver, and uses the selection signal to display the selected portion of the image on a normal receiver without geometric distortion. In another embodiment, a decoder allows television signals with the normal aspect ratio to be displayed on receivers having widescreen aspect ratios, without geometric distortion.
