Yintoni i-ATSC 3.0 tuner
Ukufumana umfanekiso opheleleyo wokuba yintoni i-ATSC 3.0 tuner, masiqale sifunde malunga nokuba i-ATSC imele ntoni. Ngokupheleleyo, ibhekisela kwiKomiti yeeNdlela eziPhambili zeTelevishini, i-Inc., eyiNPO yehlabathi jikelele (umbutho ongenzi nzuzo) oye waphuhlisa umgangatho we-ATSC 1.0 ukususela. 1996. Indima yayo ephambili kukuphuhlisa imigangatho kamabonwakude yedijithali eyenza i-high-definition (HD) kunye nosasazo lwesandi esijikelezileyo.
Ngokungafaniyo ne-ATSC 1.0, exhasa usasazo lwe-HD ngesisombululo esiphezulu se-1080 (1920 × 1080) kunye nomlinganiselo we-16: 9, i-ATSC 3.0 eyasungulwa ngo-2020 inika umgangatho ophezulu kakhulu kuyo yonke ividiyo, iaudio, kunye nemiba yokusebenzisana. Umgangatho wevidiyo ngokusisiseko utsiba ukusuka kwi-HD egcweleyo yangaphambili ukuya kwisisombululo se-4K Ultra HD nge-HDR kunye neefomathi zomsindo ezintywilayo ezixhaswayo, umzekelo, iDolby Atmos kunye Umsindo weMPEG-H.
Nangona kunjalo, zonke ezi mpucuko ekujongeni nasekuphulaphuleni umgangatho ayisiyiyo eyona nto ibalulekileyo eqinisekisa ukuba i-ATSC 3.0 ibhalwe njenge "NextGen" yeTV, ebonisa umgangatho wokusasaza wesizukulwana esilandelayo. Kukudityaniswa kunye nokusasazwa kweProtocol ye-Intanethi (IP) kulo mgangatho mtsha ochaza ubume bayo benguqu. Isiseko se-IP esinikwe amandla yi-intanethi, sivumela usasazo lweTV lwendabuko ukuba ludibanise kunye neempawu ezisekelwe kwi-intanethi, ezifana nevidiyo kwimfuno, iintengiso ezijoliswe kuyo, kunye nomxholo owenziwe ngumntu.
Ukuhanjiswa komqondiso ophuculweyo kunye nokwamkelwa komgangatho omtsha wokumodareyitha we-orthogonal frequency-division multiplexing (OFDM) ukuguqula idatha yedijithali ibe yimiqondiso yefrikhwensi kanomathotholo efanelekileyo yokuhanjiswa yenye imbalasane ye-ATSC 3.0. Xa kuthelekiswa nokumodareyitha kwe-8VSB endala kwi-ATSC 1.0, i-OFDM isebenzisa amaza okuthutha amaninzi ahanjiswa ngaxeshanye kwiinqununu zedatha ezincinci, ezithumela ngaphezu kwee-subcarriers ezininzi ze-orthogonal (ezingekho ngaphezulu). Oku kuqinisekisa ukuba abaphazamisi omnye komnye, okwenza inkqubo ixhathise ngakumbi kwiindlela ezininzi ezigqwethekileyo kwaye zilungele izixhobo eziphathwayo neziphathwayo.
Ulwamkelo olwandisiweyo kunye nokusebenza okubanzi kuzo zombini izixhobo ezisisigxina kunye nezixhobo eziphathwayo zifumana ukongezwa kokwamkelwa kwabasebenzisi kunye nokuhambelana ngasemva kweetuneli ze-ATSC 3.0 kuba ngokuqhelekileyo zibandakanya iishuni ezimbini zokuphatha zombini i-ATSC 1.0 kunye nemigangatho ye-3.0. I-ATSC 3.0 tuner, ngoko ke, inokufumana kwaye idlale zombini i-ATSC 1.0 kunye ne-ATSC 3.0 yosasazo ye-ATSC XNUMX, iguqule ibe yifom enokuthi ijongwe ngeefomathi zomsindo eziphuculweyo nakweyiphi na isikrini seTV. Ngokusisiseko iguqula iseti yeTV eqhelekileyo ibe sisixhobo esikrelekrele ngakumbi, esiguquguqukayo ngakumbi, kunye nesixhobo esisebenzisanayo esibonelela kungekuphela nje ukujongwa okuphezulu kunye nomgangatho wokwenza ngokwezifiso kodwa kunye nokusebenzisana kunye nobuntu obungakumbi.
I-ATSC 3.0 igubungela imarike
Ngokufana nezinye iitekhnoloji zokubonisa imidiya ehambelanayo, kukho iimfuneko ezithile ekufuneka zizaliseke ngaphambi kokuba itekhnoloji yokubonisa ibonise ngokupheleleyo amandla ayo. Kwi-ATSC 3.0 tuners, enye yezona zinto zicacileyo zezinto ezifunekayo kukulungelelaniswa kwemithombo yosasazo kunye nomxholo okwazi ukuhambisa iimpawu ze-ATSC 3.0.
Iindaba ezimnandi zezokuba ngasekupheleni kuka-2024, ukusuka kuMntla Merika ukuya eMzantsi Merika naseAsia, ngaphezulu kwe 80% yabasasazi kumazwe afana ne-United States, iSouth Korea, kunye neJamaica sele beyi-ATSC 3.0-ilungile. Amanye amazwe, anje ngeBrazil, Canada, India, kunye neMexico, kulindeleke ukuba afumane i-ATSC 3.0 yokwamkelwa kwamaza.
Amathuba omthengisi kwi-ATSC 3.0 tuner market
I-ATSC 3.0 tuners: Iifom ezahlukeneyo zezinto
Imakethi ye-ATSC 3.0 tuner yangaphandle ibonelela ngezinto ezininzi ezahlukeneyo, ezisebenza njengethuba elinengeniso kubathengisi kuba nganye yezi fom imela izibonelelo ezahlukeneyo kunye nabaphulaphuli ekujoliswe kubo. Enye yezona ndlela ziqhelekileyo kunye neendleko ezisebenzayo yi-ATSC 3.0 tuner, eziza kwifomathi ye-dongle ye-USB. Ezi I-ATSC 3.0 iishuni ze-USB zikhaphukhaphu kwaye kulula ukuzithwala ngokujonga ubungakanani bazo obubambekayo nobuphathekayo. Zihlala zi-plug-and-play kwaye zinokudibaniswa ngokulula ngaphandle kwenkqubo yokufakela enzima. Enyanisweni, ezi I-ATSC 3.0 izinti ze-USB zibonelela ngobulula kunye nobubhetyebhetye obusebenziseka lula obulungele ukusetwa kwezinto eziphathwayo nezimileyo, apho abathengisi banokuzuza kuzo ukuze bajolise kuzo zombini iimarike eziphathwayo nezisisigxina.
Ngaphandle koguqulelo olulula nolungenangxaki yeATSC 3.0 USB TV tuners, ezimele ATSC 3.0 iibhokisi zeTV or Iibhokisi ze-ATSC 3.0 zokuseta-phezulu bandakanya elona thuba lintsokothileyo, eliphambili lokuthengisa le-ATSC 3.0 yabalandeli betuna abanomdla okanye abachwephesha ngakumbi. Ezi tuner eziza kwiibhokisi zokuseta-phezulu zihlala zibizwa ngokutshintshana ATSC 3.0 abaguquli.
Nangona kunjalo, kuyafaneleka ukuba uqaphele ukuba igama elithi "umguquli" linokudukisa kuba, ngokungafaniyo neebhokisi ze-analog-to-digital converter ezivela kwixesha le-ATSC 1.0, abaguquli be-ATSC 3.0 abavelisi uphawu lwe-analog. Endaweni yoko, bakhupha isignali yedijithali (ngokuqhelekileyo nge-HDMI) efanelekileyo kwiiTV zanamhlanje. Yiyo loo nto, i-ATSC 3.0 yebhokisi yokuguqula iyafana nje netuner, ngaphandle kokuba yituner yangaphandle eyenza ukuba i-ATSC 3.0 yamkelwe kwi-TV engayihlanganisiyo.
Ukubhukuqa ngokupheleleyo imbonakalo yemveli yokusetyenziswa kweetuneli zeTV, enye imo ye-ATSC 3.0 tuner inika umdla kuba nangona iyitonela yeTV, isebenza kakuhle ngaphandle kweeTV. Indima yeTV, endaweni yoko, ithatyathelwa indawo yi-motherboard yekhompyuter ngePCIe slots, evumela abasebenzisi ukuba babukele kwaye barekhode emoyeni i-ATSC 3.0 kamabonwakude ngokuthe ngqo kwiiPC zabo emva kokufaka i-ATSC 3.0 PCIe Tuner Cards. Ngeetuneli ze-ATSC 3.0 ezifumaneka kwiifomu zekhadi le-PCIe, iikhompyuter ziyakwazi ukufumana kwaye zichaze usasazo lwe-NextGen TV, ukuphelisa imfuno yeeTV, kunye nokubonisa ithuba elihle lokuba abathengisi bangene kwimarike esekwe kwiPC.
I-ATSC 3.0 iityhuna: Ngeempawu eziphambili
Ehlabathini apho ukudibanisa kubonakala kungekuphela nje into eqhelekileyo kodwa isiqhelo esibalulekileyo, ngokuqinisekileyo kuyanceda ukuhenda abathengi abaninzi ngokunikezela ngeeshuni ze-ATSC 3.0 kunye nezinye iimpawu ezongezelelweyo. An Ituner ye-ATSC 3.0 enerekhodi yevidiyo yedijithali (DVR) ukusebenza, umzekelo, kuvumela abasebenzisi ukuba barekhode abayithandayo kumxholo we-OTA (phezu kwe-air), ukongeza ixabiso elibonakalayo elibonakalayo kubasebenzisi abafuna ukuguquguquka kunye nokulawula umxholo wabo wokubukela.
Ngeli xesha, kukho nezinye iituneli eziphambili ze-ATSC 3.0 eziza neenkonzo ezongezelelweyo zoqhagamshelo, kubandakanya iimpawu ezinjengeBluetooth, Ethernet, kunye neWi-Fi.
