Okuhlangenwe nakho kwendawo yaseshashalazini akuphelelanga ngaphandle kwe-TV noma iprojekti yevidiyo ukubuka izinhlelo zakho ezizithandayo ze-TV, ama-movie, nokusakaza okuqukethwe. Lapho uya kumthengi we-electronics esitolo sendawo yokuthengisa ukuze athathe i-TV, umthengi ongase akwazi ukuphazamiseka ngezinye izikhathi ngokukhetha nokuphakama okukhulu kweTV ukuze akhethe. Akukona kuphela ukuthi ama-TV afika ngobukhulu obukhulu namancane, kunesinye isici okufanele siqaphele ukulinganiswa kokubonakala kwesikrini.
Ukulinganiswa kokubonakala kweskrini
Ukulinganiswa kokubonakala kweskrini kubonisa ububanzi obuningi be-TV noma iProjection screen (kokubili ama-cinema neshashalazi yasendlini) maqondana nalo ukuphakama kwalo. Isibonelo, ama-TV amaningi andala ase-CRT (amanye asetshenziswayo) anezinga lesici se-screen ye-4x3, okubanika ngaphezulu kokubukeka kwe-squarish.
Lokho okushiwo yi-4x3 ukuthi yiwo wonke amayunithi angu-4 ekubukweni kwesikrini esinqunyiwe, kunamayunithi angu-3 wokuphakama kweskrini okuqondile.
Ngakolunye uhlangothi, kusukela kokusungulwa kwe-HDTV (futhi manje i- 4K Ultra HD TV ), izilinganiso zesici se-TV zesikrini manje zilinganiselwe nge-aspect ratio ye-16x9, okusho ukuthi kuwo wonke amayunithi angu-16 ekubukweni kwesikrini esinqunyiwe, isikrini sinamayunithi angu-9 ukuphakama kwesikrini.
Ngamazwi wesimbulo, lezi zilinganiso zivezwa ngendlela elandelayo: 4x3 kuthiwa yi-1.33: 1 aspect ratio (amayunithi angu-1.33 wesigcawu esinqunyiwe kuya ku-1 unit yokuphakama okuqondile) futhi i-16x9 iboniswa njenge-1.78: 1 aspect ratio (1.78 : Amayunithi angu-1 ububanzi obunqamule ngokumelene neyunithi eyodwa yokuphakama okuqondile).
Usayizi we-Screen Diagonal vs Umbukiso Weskrini / Ukuphakama Kwama-16x9 Ukulinganisa I-TV
Nazi ezinye izilinganiso ezijwayelekile ze-diagonal ze-TV, ezihunyushwe ebubanzi beskrini nokuphakama (zonke izinombolo zishiwo amayintshi):
- 32 (Diagonal) = 27.9 (W) x 15.7 (H)
- 40 (Diagonal) = 34.9 (W) x 19.6 (H)
- 42 (Diagonal) = 36.6 (W) x 20.6 (H)
- 43 (Diagonal) = 37.5 (W) x 21.1 (H)
- 46 (Diagonal) = 40.1 (W) x 22.6 (H)
- 47 (Diagonal) = 41.0 (W) x 23.0 (H)
- 50 (Diagonal) = 43.6 (W) x 24.5 (H)
- 55 (Diagonal) = 47.9 (W) x 27.0 (H)
- 60 (Diagonal) = 52.3 (W) x 29.4 (H)
- 65 (Diagonal) = 56.7 (W) x 31.9 (H)
- 70 (Diagonal) = 61.0 (W) x 34.3 (H)
Ububanzi beskrini nobude bokuphakama okubalulwe ngenhla kunikeza umthengi imininingwane eyinhloko yokuthi i-TV ingafanelana kanjani nendawo esinikeziwe. Noma kunjalo, ububanzi beskrini obukhulunywe, ukuphakama, nokulinganisa okufakiwe akukhipha noma yiliphi uhlaka olwengeziwe lwe-TV, i-bezel, kanye nobukhulu bokuma. Ngokuqinisekile thatha ithayinti nawe lapho uthengela i-TV ukuze ukwazi ukuhlola konke ububanzi obungaphandle befrimu ye-TV, i-bezel, nokuma.
Izilinganiso zemibukiso kanye nokuqukethwe kwe-TV / movie
Nge- LED / i-LCD ne- OLED TV manje izinhlobo ezitholakalayo (i-CRT TV manje ayifani kakhulu, ama-TV avamile we-Projection avaliwe ngo-2012 futhi i- Plasma yavalwa ngasekupheleni kuka-2014 ), umthengi manje udinga ukuqonda isilinganiso se-screen ye-16x9.
Ama-TV ane-16x9 yesici sombukiso weskrini afaneleke kakhulu kunani elikhulayo lezinhlelo ezibukwayo ezibucayi ezingu-16x9 ezitholakala kwi-Ultra HD Blu-ray, Blu-ray, iDVD, ne- HDTV ukusakazwa.
Noma kunjalo, kusekhona abanye abathengi asetshenziselwa ukubuka isikrini esiphezulu se-4x3.
Ngeshwa, ngenxa yenani elikhulayo lohlelo olubanzi, abanikazi bama-TV asebekhulile angu-4x3 babukela inombolo ekhulayo yezinhlelo ze-TV nama-DVD ama-movie anamabha amnyama phezulu nangaphansi kwezikrini zabo (eyaziwa ngokuthi ibhokisi le-mailbox).
Ababukeli abaningi, abangajwayele lokhu, bacabanga ukuthi bayakhohliswa ngokungenawo wonke umshini we-TV ogcwele isithombe. Lokhu akunjalo.
Nakuba i-16x9 manje isici esijwayelekile kunazo zonke ozothola ukubukwa kwe-TV ekhaya, kunezinye izilinganiso eziningi ezibonakalayo ezisetshenziselwa ukubukwa kwemidlalo yaseshashalazini, isethulo se-cinema yezohwebo, nokubonisa ihluzo zekhompyutha.
Amaningi amafilimu ayenziwe emva kuka-1953 abe (futhi aqhubeka) aqoshwa emafomethi ahlukahlukene ajwayelekile, njengeCinemascope, Panavision, Vista-Vision, Technirama, Cinerama, noma amanye amafomethi amafilimu amakhulu.
Indlela Ama-movie Wesikrini Abonakala Ngayo Ama-TV angu-4x3
Ukuze ubonise amafilimu wesikrini ukuze agcwalise isikrini sonke ku-TV eyayidala ye-4x3, ngezinye izikhathi aphinde ahlelwe kabusha kufomethi ye-Pan-no-Scan, ngomzamo wokufaka okuningi ngangokunokwenzeka njengesithombe sokuqala.
Ukufanekisa lokhu, thatha isibonelo lapho abalingiswa ababili bekhuluma khona, kodwa ngamunye umile ezinhlangothini eziphambene nesithombe esibuhlaza. Uma kuboniswe isikrini esigcwele ku-TV ye-4x3 ngaphandle kokuhlelwa okunye, wonke umbukeli uzobona kungaba isikhala esingenalutho phakathi kwezinhlamvu.
Ukulungisa lokhu, abahleli kumele balandele isimo sokukhululwa kwevidiyo ngokuzulazula kusuka kumlingiswa owodwa kuya komunye lapho bekhuluma futhi bephendula omunye nomunye. Kulesi simo, noma kunjalo, inhloso yomqondisi wefilimu ishintshwe kakhulu, ngoba umbukeli akawuboni konke okwakhiwa kwesimo sokuqala, kufaka phakathi noma yikuphi ukubonakala komzimba noma ulimi lomzimba ngokuphendula omunye umlingiswa okhuluma.
Enye inkinga ngale nqubo ye-Pan-and-Scan yithonya lokunciphisa izigcawu zesenzo. Isibonelo salokhu yikhosi yezinqola ngo-1959 kaBen Hur. Esikhathini sokuqala esibucayi esibucayi (esitholakala kwiDVD nase-Blu-ray - Thenga From Amazon), ungabona wonke umthelela kaBen Hur nabanye abagibeli bezinqola njengoba bexabana ukuze babeke isikhundla. Esikhathini se-Pan-and-Scan, ngezinye izikhathi kusakazwa ku-TV, konke okubonayo ukusika ikhamera ukuvala amahhashi nezinsolo. Zonke ezinye izinto ezikulo luhlaka lwangempela alukho lutho, kanye nezinkulumo zomzimba zabashayeli bezinqola.
I-Side Practical Of 16x9 Ukulinganisa Ukulinganisa Ama-TV
Ngokufika kwe-DVD, i-Blu-ray, nokushintshanisa kusuka ku-analog kuya ku-DTV ne-HDTV yokusakazwa, ama-TV anezikrini ezisondelene kakhulu nakweyesikrinini se-movie eseshashalazini angcono kakhulu ekubukeni kwe-TV.
Nakuba i-16x9 aspect ratio ingase ibe ngcono ekubukeni okuqukethwe kwe-movie, yonke i-TV yenethiwekhi (enezimbalwa ezimbalwa) kanye nezindaba zendawo, iye yazuza kulolu shintsho. Imicimbi yezemidlalo, njengebhola noma ibhola lezinyawo, ifaneleka kahle kule fomethi ngokuthi manje ungathola yonke insimu ekudutsheni okubanzi okude endaweni yokude eseduze nendawo eseduzane esivela kuyo.
I-TV ye-16x9, i-DVD, ne-Blu-ray
Uma uthenga i-DVD noma i- Blu-ray Disc, izikhathi eziningi zifomathiwe ukubukwa kwesikrini. Ekufakweni kwe-DVD ungabona imibandela ye- Anamorphic noma iphakanyisiwe kumathelevishini angu-16x9 emaphaketheni. Lawa magama abaluleke kakhulu, futhi ayasebenza, kubanikazi bama-TV angu-16x9.
Lokho kusho ukuthi isithombe sibekwe kwi-DVD ngendlela efomile ehambelanisiwe, lapho idlalwa ku-TV ye-16x9, itholakele futhi ibuyele emuva ngokulinganayo ngesilinganiso esifanayo ukuze isithombe esiphezulu sikhonjiswe kulesilinganiso esifanele ngaphandle kokuphazamiseka kwesimo.
Futhi, uma isithombe esibuhlaza sikhombisa kuthelevishini ejwayelekile ye-4x3, kuboniswa ngesakhiwo se-letterboxed, lapho kukhona khona imigwaqo emnyama phezulu nangaphansi kwesithombe.
Kuthiwani Ngawo Wonke Awamabhayisikobho ama-4x3 asebekhulile ne-TV Programming
Uma ubukela ama-movie amadala noma izinhlelo ze-TV ngendlela ye-TV ye-16x9 yobude be-TV, isithombe sisekelwe esibukweni futhi imishayo emnyama ivela ezinhlangothini zesikrini njengoba kungekho sithombe okufanele senziwe kabusha. Akukho lutho olungalungile nge-TV yakho - usabona yonke isithombe esikrinini - kuwukuthi njengoba nje i-TV yakho manje inebubanzi beskrini, okuqukethwe okudala akunawo ulwazi lokugcwalisa isikrini sonke. Lokhu kuphazamisa abanye ababukeli be-TV, futhi, ukuze bahambisane nalesi sikhathazo, abanye abahlinzeki bokuqukethwe bangase bafake imingcele emhlophe noma ephathekayo ukuze bagcwalise izindawo zesikrini esimnyama.
Noma kunjalo, kufanele futhi kuboniswe ukuthi ngenxa yezilinganiso ezihlukahlukene ezisetshenziselwa ukukhiqizwa kwe-movie, ngisho nokubukwa kwe-TV ye-16x9 ye-TV, ababukeli be-TV bangase bahlangane nemigoqo emnyama , manje kuphezulu nangaphansi kwesithombe.
Okubalulekile
Indawo yaseshashalazini yasendaweni ithola ukuthandwa kakhulu ngabathengi. I-Blu-ray, i-DVD, umsindo ozungezile, nama-TV ane-16x9 ye-aspect ratio iletha isipiliyoni somsindo / ividiyo esiyiqiniso ngaphezulu ekamelweni lokuphila noma lokuzijabulisa.
