Amava asekhaya asetshenziswanga angagqibekanga ngaphandle kweTV okanye iprojekti yevidiyo ukujonga iinkqubo zakho ezizithandayo zeTV, iifilimu, kunye nomxholo wokusakaza. Xa uya kumthengi wendawo yokuthengisa i-electronics ukuze athathe iTV, umthengi onokubakho ngethuba ngezinye iinkxalabo ngokukhethwa kunye nobukhulu beTVs ukuba akhethe. Akukona nje ukuba iiTV ziza kubungakanani obukhulu kunye namancinci, kukho enye into ekumele ikwazi ukuyijonga kwi-Screen Aspect Ratio.
Uhlobo lweSkrini sokuBaluleka oluchazwe
Ukubonakala kobukhulu beSkrini kubonisa ububanzi obungqambileyo beTV okanye iProject screen (kubini iikhamera kunye nendawo yokuzonwabisa yasekhaya) ngokubhekiselele kuyo ukuphakama kwayo. Ngokomzekelo, ii-TV ze-CRT ezindala ze-analog (ezinye zisasetyenziswa) zinomlinganiselo weskrini we-4x3, obanika ngaphezulu ubukeka obukhulu.
Oko kuthethwa yi-4x3 kukuthi kuzo zonke iiyunithi ezi-4 kwibubanzi besikrini esingaphezulu, kukho iiyunithi ezi-3 zokuphakama kwesikrini.
Ngakolunye uhlangothi, ukususela kokusungulwa kwe-HDTV (kwaye ngoku i- 4K Ultra HD TV ), ukulinganiswa kwemilinganiselo yesikrini seTV kulungelelaniswa nobukhulu be-16x9, oku kuthetha ukuba kuzo zonke iiyunithi ezili-16 kwibubanzi besikrini esingaphezulu, isikrini sinamaqela angama-9 ukuphakama kwesikrini.
Kwiimpawu ze-cinematic, ezi zibonakaliso zibonakaliswe ngendlela elandelayo: 4x3 ibhekiselwa kumlinganiselo we-1.33: 1 (ii-1.33 iiyunithi zobubanzi obunqamle kwi-1 unit of height vertical) kunye ne-16x9 iboniswa njengomlinganiselo we-1.78: 1 (1.78 : Iiyunithi ezili-1 zobubanzi obunqamlekileyo malunga neyunithi ye-height height).
I-Diagonal Screen Size vs Ububanzi beSkrini / Ukuphakama Kwi-16x9 Imilinganiselo ye-TV
Nazi ezinye izicatshulwa eziqhelekileyo zeeskrini zeTV, eziguqulelwe kwisikrini ububanzi kunye nokuphakama (onke amanani achazwe kwiintshi):
- 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 bekrini kunye nokuphakama kwemilinganiselo echazwe ngasentla kunika umboleki ulwazi oluphambili malunga nendlela iTV ingafanelwa ngayo kwindawo esinikeziwe. Nangona kunjalo, ububanzi besikrini esicacisiwe, ukuphakama, kunye nemilinganiselo ye-diagonal ayifaki naluphi na uluhlu olongezelelweyo lweTV, i-bezel, kunye nobukhulu bomda. Ngokuqinisekileyo thabatha iteksi kunye nawe xa uthengela i-TV ukuze uhlolisise yonke imilinganiselo yangaphandle yesakhelo seTV, i-bezel, kunye nokuma.
Imilinganiselo yokujonga kunye ne-TV / I-Movie Content
I- LED / i-LCD kunye nee-TV ze- OLED ngoku iindidi ezikhoyo (ii-TV ze-CRT zisoloko zinqabile, iiTV eziPhambi kweeProjection zavalwa ngo-2012 kwaye iPlasma yavalwa ngasekupheleni kuka-2014 ), umthengi ngoku kufuneka aqonde ubukhulu be-screen ye-16x9.
I-TV kunye ne-16x9 yobukhulu besikrini se-screen zilungele ukunyuka kweprogram ye-16x9 yesikrini esiphezulu kwi-Ultra HD Blu-ray, Blu-ray, iDVD, kunye ne- HDTV .
Nangona kunjalo, kusekho abanye abathengi abasebenzisa ngakumbi kwisikrini esiphezulu se-4x3.
Ngelishwa, ngenxa yemali eyongeziweyo yenkqubo ekhusileyo, abanikazi bee-TV ezidala ze-4x3 zibukele inani elikhulayo leenkqubo zeTV kunye nee-movie ze-DVD kunye nemigca emnyama phezulu kunye nezantsi kwezikrini zabo (eyaziwa ngokuba yi-letterboxing).
Ababukeli abaninzi, abangaqhelekanga kule nto, bacinge ukuba baqeshwe ngokungenayo yonke ifowuni yeTV egcwele umfanekiso. Oku akunjalo.
Nangona i-16x9 ngoku iyona nto ichaphazelekayo oya kuhlangana ngayo nokubukela kweTV ekhaya, kukho ezinye iindidi ezibonakalayo ezisetyenziselwa ukubonwa kwethala leemidlalo, ukuboniswa kwe-cinema yezorhwebo kunye nokubonisa imifanekiso yekhompyutheni.
Uninzi lwamafilimu olwenziwe emva kowe-1953 lwalukho (kwaye luqhubeka lukho) lufakwe kwiifom ezahlukeneyo ezizikhuselekileyo, ezifana neCinemascope, iPanavision, Vista-Vision, Technirama, Cinerama, okanye ezinye iifomati eziqingqiweyo zefilimu.
Iifilimu eziKhenkcezayo ziboniswa njani kwii-TV ze-4x3
Ukuze ubonise iifilimu ezibuhlaza ukuze zizalise yonke isikrini kwi-TV emide ye-4x3, ngamanye amaxesha aphinde ahlelwe kwakhona kwifomathi yokuPhakanya kunye nokuSkena, kunye nomzamo wokubandakanya ubuninzi bomfanekiso wokuqala.
Ukuzekelise oku, khawuthathe umzekelo apho abalinganiswa ababini bexoxa omnye komnye, kodwa ngamnye umi kumacandelo athile omfanekiso weskrini. Ukuba uboniswe isikrini esipheleleyo kwi-TV ye-4x3 ngaphandle kokuhlelwa kwakhona, wonke umbukeli uya kubona kuza kuba yithuba elingenanto phakathi kwabalinganiswa.
Ukulungisa oku, abahleli kufuneka balandele umcimbi wokukhutshwa kwevidiyo ngokuxhuma kwisicatshulwa esinye ukuya kwelinye njengoko bethetha kwaye baphendulane. Nangona kunjalo, iinjongo zomlawuli wefilimu ziguqulwe kakhulu, kuba umbukeli akayi kubona yonke imifanekiso yendawo yangaphambili, kubandakanywa nasiphi na isibonakaliso sobuso okanye ulwimi lomzimba ngokuphendula komnye umntu othethayo.
Enye ingxaki ngale nkqubo yePan-and-Scan yempembelelo yokunciphisa imifanekiso yesenzo. Umzekelo wale yintambo yenqwelo yenqwelo ngo-1959 ngu-Ben Hur. Inqobo yomsindo wesibhakabhaka (efumaneka kwiDVD ne-Blu-ray - Thenga kwi-Amazon), unokubona yonke impembelelo kaBen Hur kunye nezinye iinqwelo zokuhamba ngeenqwelo zokulwa njengoko zilwa. Kwimiqulu ye-Pan-and-Scan, ngamanye amaxesha usasazwa kwiTV, yonke into oyibonayo ukukhawulwa kwekhamera ukuvalela amahashe kunye neengcongolo. Yonke into ekhoyo kwisiqalo sokuqala ayilahlekanga ngokupheleleyo, kunye nemiboniso yomzimba yabathathi beenqwelo.
I-Side Practical Of 16x9 Imilinganiselo yokulinganiswa kweTV
Ngokuza kweDVD, i-Blu-ray, kunye ne-switchover ukusuka kwi-analog ukuya kwi-DTV kunye ne-HDTV yokusasazwa, ii-TV kunye nezikrini ezithandwe ngokuthe ngqo kweso sihenqo se-movie ziboniswa bhetele ukubukela iTV.
Nangona i-16x9 yesilinganiselo somlinganiselo ingcono kakhulu ekubukeni umxholo we-movie, yonke i-TV yochungechunge (kunye nemibalwa embalwa) kunye neendaba zendawo, ziye zazuza kulolu tshintsho. Iziganeko zezemidlalo, ezifana nebhola okanye ibhola lebhola, zifanelekile kule fom ekuthi ngoku unako ukufumana yonke intsimi kwelinye ipopu ephakamileyo kwindawo ekufutshane nayo kunezibhengezo ezikude esasetyenzisiweyo.
I-16x9 iTV, iDVD, kunye ne-Blu-ray
Xa uthenge i-DVD okanye i- Blu-ray Disc, amaxesha amaninzi ifomathiweyo ukubukela kwideskrini. Kwi-DVD yokupakisha ungabona i-Anamorphic okanye i- Enhanced For Televisions kwi- 16x9 . Le migaqo ibaluleke kakhulu, kwaye iyasebenza, kubanikazi bee-TV ze-16x9.
Kuthetha ukuthini ukuba umfanekiso ubekwe kwiDVD kwifomati eqhotyoshelweyo leyo, xa idlalwe kwi-TV ye-16x9, ifunyenwe kwaye isetyenziswe ngokuphindaphindiweyo kwinqanaba elifanayo ukwenzela ukuba umfanekiso wesibrari uboniswe kwisilinganiselo esifanelekileyo ngaphandle kokuphazamiseka kwesimo.
Kwakhona, ukuba umfanekiso weskrini uboniswe kumabonakude omgangatho we-4x3, uboniswa kwifomati ebhaliweyo, apho kukho imigca emnyama phezulu nangaphezulu komfanekiso.
Kuthiwani Ngabo Bonke Abo Badala Abamafilimu ama-4x3 kunye ne-TV Programming
Xa ubukela iifilimu ezidala okanye i-TV kwi-TV ye-16x9 yobukhulu beTV, umfanekiso uhlala kwisikrini kunye nemivalo emnyama ibonakala emacaleni kwesikrini njengoko kungekho mfanekiso oza kubalwa kwakhona. Akukho nto iphosakeleyo ngeTV yakho - usabonayo yonke imifanekiso kwisikrini - oko nje ukuba i-TV yakho ngoku inebubanzi obubanzi besikrini, umxholo omdala awunazo iinkcukacha zokugcwalisa isikrini sonke. Oku kuphazamisa abanye ababukeli beTV, kwaye, ukuba bajikeleze le ntlungu, abanye abanikezeli bokuqukethwe banokufaka imida emhlophe okanye ephathekayo ukuze bazalise indawo ye-screen.
Nangona kunjalo, kufuneka kwakhona kubonakaliswe ukuba ngenxa yemilinganiselo eyahlukeneyo esebenzayo kwimveliso ye-movie, kwimizuzu ye-16x9 yohlobo lweTV yeTV, ababukeli beTV banokuthi bahlangane nemibhobho emnyama , ngeli xesha phezulu nangaphezulu komfanekiso.
Ngaphantsi
Iqonga lasekhaya lifumana ngakumbi kwaye lithandwa kakhulu ngabathengi. I-Blu-ray, i-DVD, i-sound surround, kunye neTV kunye ne-aspect ratio ye-16x9 izisa i-audio / video yamazwi angakumbi kwiindawo zokuhlala okanye zokuzonwabisa.
