Yilungiselele Izinketho Zezingxenyeni Zengxubevange Zezingxubevange ze-TV
Njengoba ama-TV athola amandla amasha, kanye nezinketho ezintsha zokuxhumeka, kufika isikhathi lapho izinketho zokuxhumana ezindala, ezisetshenzisiwe ezingasetshenziselwa ukufakwa. Njengomphumela, wehla ngenombolo, ehlanganisiwe, noma empeleni aqedwe. Yilokho okwenzekayo ngobuningi be- LCD ne- OLED TVs manje ezinikezwa ukudayiswa emphakathini.
Ukuxhumeka kwe- S-Video ne-DVI sekuvele kuvele, nenombolo ye- Component , nomphathi wesilinganiso eside-eside, Umhlanganisi, ukuxhumeka kwevidiyo manje sekumbalwa ngenombolo - eqinisweni, ukuthambekela manje kuhlanganisa ukuxhumana kokubili kwevidyo nokwakhiwa kwevidyo ungakhetha kokufaka ividiyo eyodwa. Lokhu kubizwa ngokuthi "uxhumano olwenziwe". Noma kunjalo, ngaphambi kokuba ngifinyelele eminye imininingwane, ake sibuke ukuthi yikuphi ukuxhumeka kwevidiyo okuhlanganisiwe nokwakhiwa.
Ividiyo ehlanganisiwe
Ukuxhumeka kwevidiyo okuhlanganisiwe yilabo uxhumano olude olujwayele ukusebenzisa ikhebula "eliphuzi eline-RCA". Uxhumano lwevidiyo oluhlanganisiwe luthumela isignali yevidiyo ye-analog lapho izingxenye zombili zeMbala neB / W zidluliselwa ndawonye.
Lokhu kuxhumano sekusetshenziselwe amashumi eminyaka kuma-TV, ama-video projectors, abamukelayo yaseshashalazini, ama-cable / satellite amabhokisi, futhi atholakala njengesixhumi sesibili kuma-DVD abadlali / amarekhodi, ngisho nabadlali be-Blu-ray asebekhulile.
Ividiyo ehlanganisiwe, njengoba isetshenziswe kule fomethi yokuxhumeka, ihlotshaniswa nesinqumo esincane (esibizwa nangokuthi incazelo ejwayelekile) ividiyo. Futhi, kuma-TV amaningi, okokufaka ividiyo okuhlanganisiwe kuvame ukubizwa ngokuthi "ividiyo", "i-video line-in", futhi, uma kubhanwe nezimpendulo zomsindo we-analog, "AV-in".
Ividiyo Eyingxenye
Ukuxhumeka kwevidyo yevidiyo, njengoba kukhishwe kumikhiqizo yevidiyo esekelwe kubathengi empeleni kunezinhlobo ezintathu ezihlukene ezixhunyaniswe "uhlobo lwe-RCA" nezintambo ezinamacebiso okuxhumanisa okubomvu, okuluhlaza okwesibhakabhaka nobandayo, okudingeka ukuthi axhunyiwe kwizimpendulo ezihambisanayo noma iziphumo ezine-Red Green , nemibala yangaphakathi.
Emadivaysi ahlinzeka ngemigomo yevidiyo kanye nemiphumela, ukuxhumana okufakwayo / okukhiphayo kungase kuthwale izinhlamvu ezengeziwe ze-Y, Pb, Pr noma Y, Cb, Cr. Lokho okushiwo okuqala ukuthi izintambo ezibomvu neziluhlaza zithwala imininingwane yombala yesignali yevidiyo, kanti ikhebula elihlaza liphethe i-B & W noma "Luminance" (ukukhanya) ingxenye yesignali yombala.
Ividiyo esebenzayo iyashintshashintsha kakhulu, yize ukuxhumeka kwekhebula kudlula ividiyo ye-analog, amakhono akhulu kakhulu kunezingxube zevidiyo eziningana njengoba zikwazi ukuphumelela izinqumo kuze kufike ku- 1080p futhi zingaphinde zidlulise izimpawu zevidiyo ezithintekayo futhi zithuthuka .
Kodwa-ke, ngenxa yezimfuneko zokuvikela ikhophi, ukufika kwe-digital TV yokudlulisela, ne-Blu-ray disc, ikhono eliphezulu lezincazelo zokuxhuma kwevidyo le-video lishona ilanga ngoJanuwari 1, 2011 ngokusetshenziswa kwe-Image Constraint Token.
I-Image Constraint Token iyisignali engabhaliswa emthonjeni wokuqukethwe, njenge-Blu-ray Disc, ethola ukusetshenziswa kokuxhumeka kwevidiyo. Uma kutholakala, ithokheni yokucindezela yesithombe ingakhubaza ukuphakanyiswa kwe-high-definition (720p, 1080i, 1080p) ngokuvumelana namadivaysi angagunyaziwe, njenge-TV noma iprojekti yevidiyo. Noma kunjalo, lokhu akuthinti imithombo yokuqukethwe ekhona ngaphambi kokuba lokhu kukhishwa kuqaliswe.
Futhi, njengesinyathelo esilandelayo, ku-video ye-2013 yomsindo isuswe ngokusemthethweni njengendlela yokuxhuma kwi-Blu-ray Disc abadlali, futhi sikhuthazwa ukuthi abakhiqizi banciphise noma baqede le nketho kwamanye amadivaysi omthombo wevidiyo. Isibonelo, nakuba abaningi abamukelayo yaseshashalazini besakhiwa futhi bethengiswa namanje banikeza inketho yokuxhumeka kwevidiyo, ungabona inombolo yokuxhumeka etholakalayo kuncishisiwe njengoba umnyaka ngamunye olandelanayo ufinyelela emashalofini esitolo.
Ividiyo ehlanganisiwe neyengxenye kanye nama-TV amasha
Ngenxa yokuthi ukwamukelwa kwe- HDMI njengezinga eliphezulu lokuxhumeka kwevidiyo yaseshashalazini yasendlini, abakhiqizi be-TV baye bakhipha okusheshayo kwabathengi abangaziwa - "Okokufaka kwevidyo okwabelwana ngokuhlanganyela / okuhlanganyelwe" - okufanekiselwa esithombeni esingenhla.
Indlela le ndlela yokufakelwa okwabiwe ngayo ukuthi i-TV ye-input input circuit ishintshwe ukuze kokubili uxhumano lomthombo wevidiyo nomumo (kanye nokufakelwa komsindo we-analogi ehlobene) kungabanjwa. Njengoba ungabona emfanekisweni wezithombe ezingenhla, izingcingo zevidiyo ezixhunyiwe zingakwazi ukuxhumeka njengoba zingavamile, kodwa ungasebenzisa uxhumano lwe-Green component lokufaka ividiyo ukuze uxhume uxhumano lwevidiyo oluhlanganisiwe.
Kodwa-ke, uma ungaqapheli kuze kube manje, kukhona ukudoba - ngalolu hlobo lokuhlelwa "okwabiwe", awukwazi ukufaka kokubili ividiyo ehlanganisiwe kanye nomthombo wesignali wevidiyo womculo (nge-audio analog stereo audio) kuya ku-TV Ngisikhathi esifanayo.
Ngamanye amazwi, uma une-VCR, i-Camcorder endala (umthombo wevidiyo ohlanganisiwe) futhi, ake sithi, isidlali se-DVD esidala noma ibhokisi lekhebula (umthombo wevidyo wevidiyo), awukwazi ukuxhuma kokubili ku-TV efanayo kuphela inikeza uxhumano lwevidiyo oluhlanganisiwe / oluyingxenye. Kubalulekile ukuphawula ukuthi cishe kuzo zonke izimo, ama-TV anexhumano lomculo ohlanganyelwe / ohlangene kuphela olunikezwa isethi eyodwa - ngakho uma ufuna ukuxhuma kokubili i-VCR yakho ne-DVD isidlali ku-TV ngesikhathi esifanayo, uphumile inhlanhla - ngaphandle ...
I-Receiver yasekhaya yasekhaya isebenza kahle
Uma ngabe unayo yonke i-TV enikeza uxhumano lwevidiyo ohlanganyelwe / ohlangene futhi kudingeka uxhumane kokubili izingxenye nomakhi (noma ngaphezulu kwengxenye eyodwa noma ingxenye) kuleyo TV, yebo, awukho inhlanhla.
Kodwa-ke, uma une-receiver yemidlalo yaseshashalazini ehlinzeka ngama-composite, i-S-video, kanye, noma okukhethwa kukho okufakwayo kwamavidiyo, kanye nokuguqulwa kwe-analog-to-HDMI noma ukuguqulwa ngevidiyo upscaling - ke okukhethwa kukho kungaba ukuxhuma konke i-composite yakho, i-S-video, nemithombo yevidyo yevidiyo (kanye nomsindo we-analog ohambisanayo) kumamukeli wendawo yaseshashalazini bese uxhuma isamukeli sekhaya yaseshashalazini ku-TV yakho ngokukhishwa kwayo kwe-HDMI.
Njengoba ngishilo ngenhla, izimpendulo eziningi zendawo yaseshashalazini zihlinzeka kokubili okufakwayo komsindo, ingxenye, kanye nomsindo we-analog audio. Futhi, uma umamukeli wakho ekhiphe ngaphakathi-upscaling, isignali yevidiyo evela emithonjeni yakho yevidyo kanye neyomthombo ingathuthukiswa ngokuqinisekile ngandlela-thile ku-TV yakho.
Kodwa-ke, qaphela ukuthi kunezinombolo ezikhulayo zamukeli bemidlalo yaseshashalazini okwamanje ehlinzeka kuphela ngemigomo ye-HDMI yevidiyo, noma nje unikeze nge-HDMI futhi inhlanganisela, kodwa akukho okukhethwa kukho kokuxhumeka kwamavidiyo, ngakho-ke uma udinga ukuvula i-AV gear endala, qiniseka ukuthi lapho uthengela isamukeli esisha seshashalazi yasendlini, lokho kunokukhetha okuxhumekayo okudingayo.
I-External Video Scaler Workaround
Uma une-receverer yasekhaya yaseshashalazini enganikeli ukuguqulwa kwe-analog-to-HDMI noma ukuphakamisa, lokho kuvimbela inkinga. Kodwa-ke, uma uthanda ukusebenza komsindo wommukeli wakho futhi ungafuni ukuthuthukisa ngaleyo ndlela, unakho ukhetho lokusebenzisa i-processor / scaler yevidiyo yangaphandle. Lokhu kuzokunika indlela yokuxhuma imithombo yakho yevidiyo nomakhi, bese usebenzisa nje ukukhishwa kwe-processor / scaler sika-HDMI ukuxhuma ku-TV - nebhonasi eyengeziwe yokunikeza isignali eyithuthukisiwe eya ku-TV esuka kulawo mthombo. Noma kunjalo, kubalulekile ukukhomba ukuthi inqubo yevidiyo yangaphandle / i-scalers ingaba yabiza kakhulu. Nazi ezinye izibonelo: Gefen, Lumagen, Atlona.
Iziphakamiso ezengeziwe
Ubhekene nenkinga yokuhlanganiswa kwezingxenye zomculo eziyingxenye / izingxenye zama-TV amasha (ngezinto ezengeziwe zokunyamalala kwazo) - ungase ucabange ngokwenza ukuhlela kwesikhathi eside.
Okokuqala, cabanga ukukopisha wonke amathoni akho e-VHS akwenzayo ku-DVD (awukwazi ukwenza amakhophi amatheyimu we-movie e-VHS amaningi athengiswa ngawo kusukela ngo-1984 ngenxa yokukopisha-ukuvikela ).
Okwesibili, uma unomdlali omdala we-DVD ongenayo i-HDMI, yisikhathi sokuthuthukisa kumdlali we- Blu-ray Disc . Labadlali abadlali nje kuphela ukudlala ama-Blu-ray Discs, kodwa ama-DVD (aphakanyisiwe ukuqala ukuqala!), Nama-CD kanye nawo. Kanti futhi, amathuba okuba, ngesimo samanje samanani kufanele ukwazi ukuthola isidlali se-Blu-ray Disc okungenani ukuthi ukhokhele lelo dala elidala leDVD uma liqala. Ngisho noma ungenasithakazelo ekuthengeni ama-Blu-ray Discs, umdlali uzodlulisa impilo yokudlala yama-DVD akho, futhi azobukeka kangcono futhi.
Okwesithathu, thuthukisa ibhokisi lakho lekhebuli / satellite kumuntu onemiphumela ye-HDMI - futhi, cabanga ngenkonzo ye-DVR ukuze ubeke esikhundleni se-VCR esebenzayo noma irekhodi le-DVD. Kubalulekile ukuphawula ukuthi ngenxa yokukhulisa ikhophi yokuvikela ikhophi ye-DVD akuyona into ewusizo yokurekhoda izinhlelo ze-TV njengoba beyiqala lapho bephuma - futhi manje kunzima ukuthola . Kodwa-ke, ungasasebenzisa ukukopisha amateyimu akho e-VHS, ongayicabangela ngaphambi kokuba i-VCR ikhala uthuli (kuleli phuzu, cishe ngeke ukwazi ukuthola elisha ukulifaka esikhundleni).
Thatha okokugcina
Ngakho-ke, ngazo zonke izinguquko zendlela esifinyelela ngayo ukuzijabulisa ekhaya, yikuphi okuzobe usalindele? Enye into eqinisekile ukuthi nakuba ama-DVD ne-Blu-ray Disc azobe eseduzane isikhathi eside, lo mkhuba ubheke ngokuqondile ukuxhuma kwe-intanethi ye-equation - ekugcineni, imidiya yemvelo izoba nemakethe emakethe amaningi njengoba ukwanda kwengqalasizinda ye-broadband ekutholakaleni , ukuzinza, nokukwazi ukukhokhela.
Futhi, kukhona umkhuba osathuthuka, nakuba usesezinyathelo zawo zokuqala, ukuqeda isidingo sokuxhumana kwangaphakathi phakathi kwezingxenye ngokusebenzisa izinketho eziningana zokuxhumana ezingenantambo . Sivele sibe ne-Wifi ne-WirelessHD (WiHD) namazinga we-WHDI we-audio nevidiyo, ne- Bluetooth, kanye nezinye izinketho , ezisetshenziselwa ukufinyelela nokusabalalisa umsindo.
Ngaphezu kwalokho, ngokusungulwa kwe- WISA (uSomlomo ongenazintambo kanye no-Audio Association) , kwenziwa izinyathelo zokwenza umgomo wokusetshenziswa kwezinketho ze-wireless ezingasetshenziswa ngisho nasezindaweni eziphezulu zokudlala ekhaya.
Ukuhlanganiswa kokuhlanganiswa kwevidyo neyomculo kuma-TV kungomunye, kuncane kakhulu, okuyingxenye yalokho okugcinwe ezinyangeni nasezinyangeni ezizayo zokuxhumana kwendawo yaseshashalazini.
