I-TV yakho iluhlaza kangakanani?
Ngamaxabiso akhulayo yamandla kunye nokufudumala kwehlabathi ngokuqhubekayo izihloko ezishisayo ngoku, abavelisi beTV bayazifumana phantsi koxinzelelo oluqhubekayo lokuhambisa umfanekiso wabo kunye neentloni xa besebenzisa amandla angaphantsi.
Ukufika kwesizukulwana esitsha se- 4K (esaziwa ngokuba yi-UHD) , kodwa kubonakala sengathi kubangela ukuba aba bakhiqizi beentsimbi ezinzulu be-headphone ecocekileyo, benombiko omtsha othi ii-TV ze-4K zisebenzisa i-30% ngaphezulu kwamandla kune- HD .
Inqaku lo mfanekiso ophazamisayo ngokuchasene nenani elichaziweyo lamaTV e-4K afumana indlela yawo emakhaya ase-US ekupheleni konyaka we-2016 kwaye unokukhangela ukuxhamla okudibeneyo kwiibhili zamandla ezizwe ezingaphezu kwezigidigidi zeedola.
Uphando
Iqela elisemva kwengxelo ebambe isohlo, iBhunga loKhuselo loLondolozo lweNdalo (NRDC), alizange nje linyathele la manani ngomoya ococekileyo, ongenanto yokuthetha. Lalinganisa ukusetyenziswa kwamandla ama-TV ama-21 - kugxininisa kumlinganiselo wesayizi we-intshi engama-55, njengokuba okwangoku kuthengiswa ngobukhulu be-TV 4K - kwinqanaba labakhiqizi kunye namanqaku exabiso, kunye nokuthatha idatha kwiinkcukacha zoluntu ze-UHD TV yamandla se benzisa. Uqikelelo lwayo lwamaninzi amakhaya aya kuba ne-TV ye-4K, okwangoku, esekelwe kuhlalutyo lwamaxabiso athengisa ngokuthengisa iTV.
Ukuya kwiinkcukacha zamabango, kuthatha njengento yokuqala ukuba kukho ii-TV ezigidi ezingama-300 ezikhoyo kwimimandla yase-US. Emva koko idibanise le nani kunye neziphumo zayo zokufunyanwa kwamandla e-TV ye-4K ukubala ukuba kwenzekani ukuba kukho ukutshintsha kwelizwe lonke ukusuka kuma-TV-36 kunye ne-TV ezinkulu kwii-TV ze-UHD, kwaye kwafika kwii-8 zeeyure eziyi-kilowatt zeeyure zokusetyenziswa kwamandla lonke. Elinganisa kathathu amandla angaphezu kwe-San Francisco yonke idla rhoqo ngonyaka.
Ixabiso lokungcola
I-NRDC yongezelela ukuba i-olowatt ezili-8 zezigidi eziliiyure ezingama-kilowatt zingagqiba ukudala izigidi ezingaphezu kwezihlanu zeetrikri ze-carbon extra pollution.
Inqakrazo namanani e-NRDC, kwakhona, kukuba ukutshintshwa kwizigqibo ezi-4K ze-UHD kukhokelela ekuthengiseni i-TV-screen. Ingxenye yesithathu yazo zonke i-TV ezithengiswa namhlanje, ngokubonakalayo, ubuncinane ubunama-intshi ezingama-50 ngobukhulu - kwaye yinyani elula ukuba iiTV ezininzi zivame ukudla amandla amaninzi. Enyanisweni, ngokweemvavanyo ze-NRDC ezinye i-TV-screen screen zibonakala zitshisa ngombane ongaphezulu kunefriji eqhelekileyo!
Njengokuba ukwanda kwamandla okusetyenziswa okwenziwe ngu-4K kwakungekho ukukhathaza ngokwaneleyo, i-NRDC ibonisa ukuba izinto ziyakwazi ukugqithisa ngokufikeleleka kobuchwephesha obuphezulu (HDR) iTeknoloji yeTV.
Impembelelo yeHRR
Ingcaciso epheleleyo ye-HDR inokufumaneka apha , kodwa ngokufutshane ingcamango engemva kwayo kukuba ikuvumela ukubukela ividiyo ngebala lokulumka olwandisiweyo-into efuna ukuba namandla angaphezulu kwiTV yakho ngenxa yokukhanya okubandakanyekayo okubandakanyekayo.
Imilinganiselo ye-NRDC ibonisa ukuba ukubukela ifilimu kwi-HDR idla phantse amandla angama-50% ngaphezu kokubukela ifilimu efanayo kwinqanaba eliqhelekileyo lezandla.
Ngeli nqanaba ndiziva ndibophekile ukuba ngiphakamise kwaye ndicinezele ukuba empeleni abavelisi beTV baye benza intsebenzo eninzi kwiminyaka yamuva nje xa kufikelelwe ekunciphiseni ukusetyenziswa kwamandla kweeTV zabo, kwaye andinakuqinisekiswa ukuba uphuculo oluqhubekayo luya kwenziwa njengoko beba ngakumbi wafumana ama-4K kwaye, ngakumbi i-HDR.
Izinyathelo ozithathayo
I-NRDC ngokwayo ichaza kumanqanaba okugqibela kwengxelo yayo yokuba sele sele uyenze izinto xa ungathenga nokusebenzisa i-TV entsha ye-4K ukunciphisa ukukhathazeka kokusetyenziswa kwamandla. Iingcebiso eziphambili ezinikezelwa kukuba usebenzisa i-TV yokukhanya ngokuzenzekelayo, apho umfanekiso uguqula ngokwamanqanaba okukhanya ekamelweni lakho; ukuba ukhangele i-TV efumana iileyile ye-Energy Star; kwaye ukuba ugweme ii modes zokuqala eziqalayo zeTV.
Njengomtsalane wekhwalithi yemifanekiso ye-TV ndineenkxalabo malunga nokuba luphi uhlobo lwamava e-AV olunokuthi luchaphazeleke ngokunyanzeliswa kwamandla okubonakala ngathi lukhuni kunikwe ukuba nzima kangakanani ihlabathi le-AV eliye lasebenza ukuze libe libala kwixesha langoku. Kodwa ngexesha elifanayo ndicinga ukuba sonke sifuna iindleko zamandla ezantsi kunye neplanethi enempilo, kunene ?!
