Imithombo ye-HD iningi
Abathengi abathengisa i-HDTV yabo ngezinye izikhathi bacabanga ukuthi konke abakubheka kukho kuncazelo ephakeme, futhi badumazeka lapho bethola ukuthi i-analog yabo eqoshiwe ibonisa ukuthi ibonakala kakhulu kunayo yonke i-HDTV yabo entsha kunokuba isetshenziswe kwisethi yabo yokudala. Ngemuva kokutshala imali eningi kwi-HDTV entsha, uthola kanjani isithombe esiphezulu esiphezulu wonke umuntu okhuluma ngaso?
Udinga Imithombo Ephezulu-Definition
Uma une-HDTV, indlela yokubuka i-HD yangempela kufanele ibe nemithombo ye-HD yangempela, njenge-satellite satellite ne-HD isevisi yekhebula, imidiya ye-HD yokusakaza, noma uhlelo lwe-HD yendawo. Ngonyaka we-2009, wonke ukusakazwa kwethelevishini kushintshwe kusukela ku-analog kuya kokuthunyelwa kwe-digital, eziningi zazo eziphezulu-definition. Enye imithombo ephezulu-definition inezingcingo ze-Blu-ray, abadlali be-HD-DVD, nekhebula noma i-satellite HD-DVRs.
Ama-DVD abhala nge-ATSC noma i-QAM tuners bangathola izibonakaliso ze-HDTV, kodwa bahlehliselwa ekuchazeni okujwayelekile ukurekhoda kwi-DVD, futhi umrekhoda weDVD akadluli isignali ye-HDTV ngokuqondile kusuka kumathuluzi ayo kuya ku-TV.

- Ikhebula le-HD noma isevisi yesathelayithi ye-HD
- Ikhebula le-HD DVR, i-HD satellite DVR, noma i-TIVO-HD noma idivayisi efanayo
- I-antenna engaphezu kwe-air ihlanganiswe nesitoreji se-ATSC ku-HDTV
- Isidlali se-Blu-ray Disc
- Ukuqeda isidlali se-DVD noma umrekhodi we-DVD nge-HDMI okukhiphayo. Lokhu akuyona i-HD yangempela, kodwa isidlali se-DVD esiphezulu singanikeza isithombe esingcono kakhulu kwi-HDTV kunesidlali se-DVD esingajwayelekile.
- Amakhamera ephezulu-definition afana ne-HDV noma ama-camcorder yefomethi ye-AVCHD, ne-compact hard drive namakhamera ememori khadi abene-HDMI yokuxhumana okukhiphayo.
Imithombo ethi Don & # 39; t Inikeza i-HD Signal
- Amarekhodi e-DVD, ukuhlanganiswa kwe-DVD / i-hard drive, kanye ne-DVD recorder / i-VCR inhlanganisela engafaki imiphumela ye-HDMI ne-DVD upscaling.
- VHS VCRs.
- Izixazululo ezijwayelekile ze-analog namakhamera edijithali.
Incazelo ephezulu kanye nokuqukethwe okuhanjiswe kusuka ku-Intanethi
Izinhlelo zokusakaza ze-TV, ama-movie, namavidiyo ngumthombo ovame kakhulu wokuqukethwe kwe-TV. Ngenxa yalokho, ama-TV amaningi amasha, abadlali be-Blu-ray Disc, namabhokisi aphezulu-ke manje ahlanganisa amandla okufinyelela okuqukethwe kwe-intanethi esekelwe e-intanethi, okuningi okungukuthi isinqumo se-high definition. Noma kunjalo, ikhwalithi yesignali yokusakaza ekugcineni ixhomeke ekutheni ukuxhumana kwakho kwe-intanethi kushesha kangakanani. Ukuxhumeka okusheshayo kwe-broadband kunconywa ikhwalithi yesithombe esihle kakhulu.
Isibonelo, amasevisi wokusakaza anganikeza isignali ephezulu-definition ye-1080p ye-HDTV yakho, kodwa uma isivinini sakho sokuxhumeka kwe-intanethi sihamba kancane, uthola izitayela zesithombe nokuphazamiseka. Ngenxa yalokho, kungadingeka ukhethe ukhetho oluphansi lokubheka okuqukethwe.
Ezinye izinsizakalo zibona ngokuzenzakalelayo isivinini sakho se-intanethi bese zifanisa ikhwalithi yesithombe yemidiya yokusakazwa kwijubane lakho le-intanethi, okwenza ukubukwa kube lula, kodwa ungase ungaboni umphumela ophezulu wezincazelo.
Isiqinisekiso I-HDTV Yakho Ithola i-HD Signal
Indlela engcono kakhulu yokuqinisekisa ukuthi ngabe i-HDTV yakho iyithola yini ngempela isignali yevidiyo ephezulu yokuthola inkinobho ye-INFO ukude kwakho kwe-TV noma ubuke umsebenzi wemenyu esesikrinini ofinyelela ulwazi lwesignali noma isimo.
Uma ufinyelela noma yimuphi wale misebenzi, umlayezo kufanele uboniswe kusikrini se-TV esikutshela isinqumo sesignali yakho engenayo, noma emibhalweni yokubala ye-pixel (740x480i / p, 1280x720p, 1920x1080i / p), noma nje ngo- 720p noma ngo-1080p .
I-4K Ultra HD
Uma unayo i- 4K Ultra HD TV , awukwazi ukucabanga ukuthi lokho okubonayo esibukweni nganoma isiphi isikhathi kungu-4K weqiniso. Kunezinto ezibalulekile, ezengeziwe, izici okufanele zicatshangelwe ngokuqondene nalokho okubonayo esibukweni. Njengoba nje nge-HD, udinga ukuba ne-Ultra HD-quality izinhlelo ukuze ubone ukuthi kungenzeka yini ithelevishini yakho.
