Ukuhlanganyela Ngomhlaba We-Digital ngezinsiza ze-Analog
Nakuba izinsuku zezingxoxo ze-analog nama-video cassette ( ama-VCRs ) aphezu kwalokho, abanye abantu basenama-TV angama-analog . Basebenzisa amabhokisi wokuguqula i-digital TV (DTV) ukubuka amasignali amadijithali kuma-TV awo a-analog. Inkinga ifika lapho befuna ukubhala umbukiso. Yilapho amaVCR afika khona.
VCR kuya Rescue
Imigomo yokusebenzisa i-VCR ukurekhoda kusuka ebhokisini lokuguqula i-DTV ihlanganisa:
- I-VCR kufanele ilandelwe ukurekhoda kusiteshi 3.
- I-VCR ixhuma kwisignali yokukhipha ibhokisi lokuguqula i-DTV. Ngamanye amazwi, ibhokisi lokuguqula kumele lixhunywe phakathi kwe-antenna ne-VCR. Ngakho-ke, ukumiswa okungenzeka oyisebenzisayo ngekhebula le-coaxial yi-antenna ku-DTV converter ku-VCR kuya ku-TV.
- Xhuma umguquli we-DTV esiteshini ofuna ukurekhoda ngaphambi kokurekhoda. I-VCR ngeke ikwazi ukushintsha iziteshi kumguquleli we-DTV.
Uyakwazi ukusebenzisa umsebenzi wokuqopha ophelelwe isikhathi kwi-VCR uma unamathela kulezi zici.
Uma lokhu kuzwakale ngokujwayelekile ukurekhoda kwikhebula ledijithali noma i-satellite set-top box, uqinisile. Kufana nokurekhoda isignali ebhokisini lekhebula ledijithali noma i-satellite receiver. Ngenkathi kungase kube yinto engathandeki, okungenani ukhetho lukhona ukurekhoda kwi-VCR ngenkathi usebenzisa ibhokisi lokuguqula i-DTV.
Ukuntuleka kokusebenzisa i-DTV Converter
Ulahlekelwa ikhono lokubuka uhlelo olulodwa bese uqopha enye ngomguquleli we-DTV.
Isizathu yi-tuner. I-VCR tuner ayinalutho ngeziteshi zedijithali ngaphandle kokubona isiteshi 3. I-converter yedijithali iyinto eyodwa ye-tuner ngakho ithola isiteshi esisodwa ngesikhathi esisodwa.
Mayelana neziteshi
Isiteshi esisakazwa esisodwa singathumela izibonakaliso eziningi kwi-band yabo ye-digital. Lezi zibizwa ngokuthi izigcawu. Ngokujwayelekile, uthola ukufinyelela kokurekhoda kulezi ziteshi uma usebenzisa ibhokisi lokuguqula i-DTV nge-antenna.
Iziteshi ezingezansi zivela into efana ne-42.1, 42.2, 42.3 nokunye okunye. Isibonelo, endaweni eyodwa, abambisene nabo be-ABC bangase bathumele ukuphakela kwe-ABC kumgudu wamasentili 24.1 kanye nesignali kuphela sezulu se-24.2.
Lokhu kungenye yezinzuzo zethelevishini yedijithali ezithwala umhlaba we-analog ngebhokisi le-DTV converter.
