Umbuzo: Ingabe amaDVD angabhala angadlalwa kuphi emhlabeni?
Impendulo: Impendulo emifushane ngu "CHA".
Nokho, kunezixazululo ezingasebenza, uma unayo imali nesikhathi.
Izwe lisebenza nezinhlelo ezimbili ezinkulu zevidiyo, i-NTSC ne-PAL.
I-NTSC isekelwe emigqeni engu-525, amasimu angu-60 / ama-30 ozimele-ngomzuzwana ohlelweni lwe-60Hz lokudlulisa nokubonisa izithombe zevidiyo. Lena yinkimbinkimbi ehleliwe lapho ifreyimu ngayinye iskena emikhawulweni emibili yemigqa engu-262, ehlangene ukuze ibonise uhlaka lwevidiyo ngemigqa engu-525 yokuskena. I-NTSC iyinhlangano esemthethweni yevidiyo ye-analog e-US, Canada, Mexico, izingxenye ezithile zaseCentral naseNingizimu Melika, eJapane, eTaiwan naseKorea.
I-PAL iyimfomethi evelele e-World ye-analog yezokusakaza ithelevishini ne-video display (i-sorry US) futhi isekelwe kumzila we-625, amasimu angu-50 / ama-25 wesibili, uhlelo lwe-50HZ. Isibonakaliso siyaphambana, njenge-NTSC, emasimini amabili, enziwe imigqa engu-312 ngayinye. Izici eziningana ezihlukanisayo ziyisodwa: Isithombe esiphezulu esiphezulu kune-NTSC ngenxa yenani elandayo lemigqa yokuskena. Okubili: Njengoba umbala wawuyingxenye yezinga kusukela ekuqaleni, ukungafani kombala phakathi kweziteshi nama-TV kungcono kakhulu. Ngaphezu kwalokho, i-PAL inesilinganiso sefreyimu esiseduze nalokho yefilimu. I-PAL inama-25 ozimele ngesilinganiso sesibili, kuyilapho ifilimu inesilinganiso sehlaka lohlaka olu-24 ngomzuzwana. Amazwe ohlelweni lwe-PAL afaka i-UK, i-Germany, iSpain, iPortugal, i-Italy, i-China, i-India, iningi le-Afrika, ne-Middle East.
Abanye abarekhoda be-DVD bangabhala ku-PAL emithonjeni ye-PAL noma i-NTSC emthonjeni we-NTSC, kodwa, abaguqulwa isignali ngesikhathi sokurekhoda - ngamanye amazwi, awukwazi ukurekhoda i-PAL disc uma umthombo wakho kuyi-NTSC noma ngokuphambene nalokho. Futhi, abarekhoda be-NTSC DVD abakwazi ukurekhoda kusuka kwi-tuner yayo ye-NTSC kuya kwi-disc kwifomethi ye-PAL.
Okuphela kokusebenza kwangempela kwalokhu kungukuthi:
Uma abangane bakho bane-DVD player ene-converter ye-NTSC-PAL eyakhelwe ngaphakathi - ezobavumela ukuba badlale i-NTSC disc bese beyibuka ku-PAL TV (noma ngokuphambene nalokho).
OK
Uma uthenga i-Converter ye-NTSC kuya ku-PAL bese uyibeka phakathi kwe-camcorder noma i-VCR kanye nerekhodi le-DVD ene-PAL yokuqopha ukuze i-DVD irekhodi ingakwazi ukurekhoda i-DVD ku-PAL.
