Yini Isixazululo Esikrini Esiphezulu Kakhulu seThebulethi?
Njengoba i-buzz engaphezu kwama-4K wezokubukwa kwethelevishini itshisa, siqala ukuzwa okuningi nokuningi mayelana ne-4k ehlasela izwe lamaphilisi. Kodwa ngenkathi izinkampani ezinjengo-Samsung zizungeze i-buzzword engu-4K, lawa maphilisi awanqamuki esigabeni sangempela sokuxazulula isikrini. Futhi nge-Apple manje esebenzisa iziboniso zabo ze-True Tone, sinomunye u-buzzword ozobhekana nawo. Ingabe sidinga ngempela amaphilisi angu-4K? Futhi i-4K ibambelela kanjani ku-Retina Display? Kuthiwani nge-Tone Yeqiniso?
Uyini ukubukwa kwe-Retina?
Ingxenye edidekayo mayelana nokubukwa kwe-Retina ukuthi iza nezinqumo eziningi zesikrini ezahlukene. Ukuboniswa kwe-4K ngokuvamile kuyisinqumo esingu-3,840x2,160 kungakhathaliseki ukuthi sibukhulu besiboniso, kodwa isinqumo se-Retina Display ngokuvamile sishintsha ngokususelwa kubukhulu besiboniso.
Njengoba kubizwa yi-Apple, ukuboniswa kwe-Retina kuyisikrini esinokuphakama kwamaphikseli okwanele kangangokuthi amaphikseli angeke akwazi ukubonwa ngeso lomuntu lapho idivayisi igcinwe ebangeni elibukwayo elivamile. I "ibanga elibukwayo elivamile" liyingxenye ebalulekile yalesi sibalo ngoba usondelene kakhulu nedivaysi, amancane amaphikseli ayodingeka abe ngaphambi kokuba ahlukaniswe omunye nomunye. I-Apple ibheka ibanga elibukwayo lokubuka i-smartphone ukuba libe ngu-10-12 amasentimitha futhi ibanga elibukwayo lokubuka ithebulethi libe ngu-15 amasentimitha.
Ukuhlukaniswa kokubukwa kwe-Retina kubalulekile ngoba noma yisiphi isixazululo sesikrini esiphakeme asihlinzeki nganoma iyiphi inzuzo yokubuka. Uma iliso lomuntu lingeke lisakwazi ukuhlukanisa amaphikseli athile, ukubonisa kubonakala njengokucacile njengoba kungaba khona. Eqinisweni, izinqumo eziphezulu zesikrini zidinga amandla amaningi wegrafu, okudonsa amandla amaningi ebhethri. Okudlulele "Ukubukwa kwe-Retina" kungaba empeleni kuphazamise kusuka kudivayisi.
Ingabe i-4k nje i-scam yi-Industry Television?
Kukhona umehluko obalulekile phakathi kwethebulethi kanye nethelevishini. Ithelevishini isetshenziswa ngokuyinhloko ukubukela ividiyo. Futhi ukuze uthole okuningi kuvidiyo esibukeleyo, isinqumo sethelevishini sethu kufanele sifane nesinqumo sevidiyo. Ngakho-ke noma amathelevishini afika ngobukhulu obuhlukahlukene, imboni idinga ukulungiswa kwesikrini okujwayelekile ukufanisa ividiyo ekhishwe ngesinqumo sethelevishini. Ngeke kwenzeke noma yini enhle ukuba nesinqumo esiphezulu sethelevishini enkulu lapho isithombe esibukweni sizoboniswa kwisinqumo esincane esinqunyiwe.
Ngakho, i-4K iyimfuneko ebalulekile embonini yethelevishini. Kodwa-ke, sisebenzisa amaphilisi ethu okuningi kakhulu kunokusakaza amavidiyo avela ku-Netflix nase-Amazon Prime . Ngokwethebhulethi, igama elithi "4K" linencazelo encane.

I-Retina Display vs 4K
Ngokuthenga ithebulethi , igama elithi "4K" kufanele libe nokukhathazeka kuphela uma ukusetshenziswa kwakho okuyinhloko ukusebenzisa idivayisi ukubuka ithelevishini nokusakaza ividiyo. Inombolo yangempela okufanele uyibuke yi-pixels-intshi (PPI) yesiboniso. I-PPI inqunywa ngokusekelwe usayizi weskrini nokulungiswa kwesikrini. Amaphilisi amaningi manje abonisa i-PPI ekuchazeni.
I -iPad Pro ye-9.7 intshi inesiboniso esingu-9.7-intshi esilinganiswa ngokulinganisa nge-2,048x1,536 isinqumo. Lokhu kunika i-PPI ye-264, i-Apple enaka ngokwanele ukuba yi-Retina Display yethebhulethi. I- Projekti ye- iPad engu-12,9-intshi inesinqumo esingu-2,732x2,048, esinika i-PPI ye-264.
Ekubukeni ithebhulethi, i-PPI yezingu-250 noma ngaphezulu ingukhiye wokushaya uhla lwe-Retina Display. Khumbula, noma yini engaphezu kokubukwa kwe-Retina nje ibangela ukuthi ithebhulethi iphonse amaphikseli amaningi asetshenzisiwe esibukweni, esondeza impilo engaphezulu kwebhethri . Okuthakazelisayo, i-iPad Mini 4 ine-PPI ye-326 esekelwe ekubeni nesisombululo sesikrini esifanayo njenge-iPad Air 2 ene-screen encane engu-7.9-intshi. Ngokungangabazeki, i-Apple icabanga ukuthi ukugcina isinqumo esifanayo kusuka kumbono wokubambisana kwakubaluleke ngaphezu kokudonsa okwedlulele ebhetri, kodwa ukubonisa ngokwayo kuzobukeka okufana nokuxazulula okuncane.
Isixazululo se-4K kuthebulethi kufanele kubhekwe kuphela kumathebulethi afana ngamasentimitha angu-12 ngokulandelana noma ngaphezulu. Yingakho amaphilisi okuqala angu-4K avame ukuba alobu bukhulu obukhulu. Amaphilisi amancane anezixazululo ezingu-4K agxuma kwi-bandwagon ngokubonisa okuzodla amandla amaningi ebhetri kepha anganikeli noma yisiphi isixazululo esicacile kune-iPad. Okuhle ngokwanele, i-Sony empeleni iveza i-smartphone ngesinqumo se-4K esinqunyiwe.

Lapho i-4K Isn & # 39; t ngempela 4K
I-Samsung yakamuva ikhishwe ithebulethi ye- "4K" ye-Galaxy Tab S3 edlala isinqumo esinqunyiwe esingu-4K esingu-2048x1536. Lesi yisinqumo esifanayo njenge-9.7-intshi iPad Pro. I-Samsung ithengisa le Galaxy Tab S3 njengethebulethi ye-4K ngoba ingayamukela ividiyo ye-4K nakuba ingenakuyikhiphela ekubonisweni kwayo. Lokhu ngokuyisisekelo kuthatha amagama okukhangisa ku-buzz endaweni yokuhlenga indawo. Kusho nokuthi kufanele ube nokungabaza kwanoma yiliphi ithebhulethi elibhekisela ngokwayo njenge-4K.
Futhi Kuthiwani Ngezwi Eliqiniso?
Iziboniso ezintsha ze-Apple zomzila wePhrojekthi ye-iPad Pro manje sezibhalwe ngokuthi "I-Tone True". Ukuboniswa kwe-True Tone kukwazi ukukhiqiza i-DCI-P3 Wide Color Gamut, okuyisilinganiso esetshenziswa umbonisi womculo. Ukuthuthela ekuchazeni "i-Ultra-High Definition" (UHD) embonini ye-TV kuhamba phambili ekubhekeni kombala wombala obanzi ngokuphambene nokwandisa isinqumo sesikrini ala 4K.
Esinye isici se-Apple's True Tone display yikhono lokubona ukukhanya okuhambisana nokushintsha umthunzi omhlophe oboniswe esikrinini ukuze ulingise umphumela wokukhanya 'ezweni langempela'. Lokhu kufana nokuthi ishidi lephepha lingase libukeke limhlophe kangakanani ngaphansi komthunzi futhi liluhlaza ngokwengeziwe ngaphansi kwelanga.

Ingabe i-4K Ekugcineni izohamba ngendlela ye-3D?
Ngenkathi i-TV ye-3D ibonakele njengengane, ama-4K amathelevishini cishe ahlala lapha. Noma kunjalo, kungathatha isikhathi eside kunokuthi abanye bacabange ngo-4K ukuze babe yizinga eliyiqiniso. Kuthatha isikhala esiningi ukugcina ividiyo engu-4K, futhi okubaluleke nakakhulu, kuthatha ukuhamba kwe-bandwidth ngaphezulu ukusakaza 4K.
Okwamanje ithatha cishe ama-Megidytes-per-second (Mbps) ama-5-6 ukuhambisa ividiyo ephezulu ye-1080p. Uma ucabangela isidingo sokuhlunga futhi uhlangabezane nezivinini ezihlukahlukene ze-Wi-Fi, ama-8 Mbps angaba ekahle kakhulu. Njengamanje, kuthatha u-12-15 Mbps ukuhambisa ividiyo engu-4K, futhi uxhumano lomqondo lube ngu-20 Mbps.
Kubantu abaningi, lokho kungadla iningi le-bandwidth abayithola kumnikezeli wabo we-inthanethi. Futhi ngisho nalabo abanokuxhumana okungama-50 Mbps bangase bazizwe behlupha kakhulu uma abantu ababili enethiwekhi yabo bezama ukubukela i-movie 4K ngesikhathi esifanayo.
Futhi ngenkathi singase sikwazi ukusebenza kulo mbandela, inkampani efana ne- Netflix noma i-Hulu Plus izobona ukwanda okukhulu kwezindleko zokusakaza ividiyo. Futhi ama-ISP afana ne-Verizon FIOS ne-Time Warner Cable kakade elwa nokubhekana nesilinganiso semikhawulthi Netflix yedwa ethatha ngesikhathi sesikhathi esiyinhloko. I-intanethi ngokwayo ingase ingabi namandla uma ngabe kuphakanyisiwe ukusakazwa kwevidiyo ye-4K yokusakazwa.
Ngakho asikho okwamanje lapho. Kodwa kusukela kumbono wamanani, amathelevishini angu-4K asondela futhi asondelene naleso silinganiso sabathengi. Eminyakeni embalwa, iningi lethu lingacabanga ukuthi imali engaphezulu kuka-100 eyichithelwe ukuthuthukiswa esibukweni se-4K ibalulekile kakhulu. Kungenzeka empeleni kuthathe isikhathi esincane kubahlinzeki be-intanethi ukuthi balungele, kodwa bayofika lapho.
Yini Ozoyidingayo Ukuze Ubone Ividiyo Ye-4K ku-Setha ye-4K ye-Television
