Umamukeli we-DVB-T2: incazelo, imininingwane, imfundo, amamodeli nokubuyekeza

Ithelevishini yedijithali kungekudala, kodwa kakade imiswe ngokuqinile emiphakathini yethu. Kodwa-ke, akubona sonke esakwazi ukuthola i-TV enezimboni zedijithali ezakhelwe ngaphakathi. Sombulula le nkinga ngezindlela ezimbili - uthenge i-TV entsha neyanamuhla noma ufake endlini yakho isamukeli encane se-DVB-T2. Ukhetho lwesibili luyinzuzo kakhulu futhi luyamukeleka, ngoba abamukeliyo ngumyalo wokunciphisa ubukhulu kunomshayeli "we-telejacket" entsha. Noma kunjalo, lapha ungaba nezinkinga ezithile, uma ungazi ukuthi yini okufanele uhambe ngesikhathi sokuthenga.

Abamukeli be-DVB-T2

Kuze kube manje, umbhoshongo we-TV nomlayezo we-analog ne-digital usakazwa ebangeni elifanayo. Ngakho-ke, ukuthola iziteshi zevidiyo eziphezulu, asikho isidingo sokufaka i-antenna entsha - i-UHF "yezimpondo" ezivamile, okuqinisekisiwe ukuthi ngamunye wethu uyoba nayo.

Kumele futhi kukhunjulwe ukuthi akuwona wonke amathelevishini akwazi "ukukhiqiza" isignali yedijithali. Yiqiniso, ukuxhuma isamukeli se-DVB-T2 "ebhokisini lithelevishini" elidala, ungabuka iziteshi zakho ezizithandayo, kodwa ngeke ubone noma yimaphi umehluko ekhwalithi yesithombe.

Abamukeli bedijithali banamuhla amadivaysi amancane abukeka afana kakhulu nabadlali beDVD. Eziningi zemibukiso zinokubonisa okulula kwe-LCD ngaphambili kwepaneli, izinkinobho zokulawula.

Ngemuva yale divayisi kukhona izixhumi zokuxhumeka ku-antenna ne-TV, izintambo ezengeziwe zekhadi le-flash, ama-adapter namanye amadivayisi, kanye nokushintsha kwamandla. Ukukhetha isamukeli se-DVB-T2, udinga ukugxila kuphaneli elingemuva.

Izici zokuthola

Isici sokuqala esibalulekile samukeli wedijithali yisisombululo sevidiyo esisekelwe. Lokhu kulungiselelwa kufanele kufane nesinqumo se-TV yakho. Ngakho-ke, uma isikrini sisekela kuphela i-SDTV, khona-ke akudingeki ukuthi uthenge ibhokisi elisethiwe-elisekela ividiyo ephezulu ye-HD - i-TV izosakazwa njengangaphambili. Okufanayo kusebenza emsebenzini we-3D owakhelwe ngaphakathi.

Ukuba khona kwezixhumi ezidingekayo zokuxhuma ibhokisi elibekiwe-ku-TV kuyiparamitha yesibili ebaluleke kakhulu. Iningi lemishini yokuxhuma usebenzisa i-RCA-cable, noma "ama-tulips". Ezinye izamukeli ezisezweni eziseDVB-T2 zisebenzisa izintambo ze-SCART kanye namachweba e-RCA.

Ngaphezu kwalokho, ungasebenzisa enye ye-interfaces eyakhelwe ngaphakathi ukuxhuma ku-TV. Ngokuvamile, lokhu ngokuvamile kuvimbela i-HDMI. Ukuba khona kwazo zonke lezi zixhumanisi kukuvumela ukuba uxhume ama-TV amabili kumamukeli oyedwa ngesikhathi esifanayo.

Ama-interfaces angene ngaphakathi

Emakethe ungathola ngokuvamile imishini ene-interface ekhonjiwe ye-USB, ngenxa yokuthi ungakwazi ukuxhuma idrayivu, ifoni nakwezinye izimo ngisho nekhompyutheni eya kumamukeli. Noma kunjalo, isamukeli esinjalo se-DVB-T2 sinokubiza kakhulu kunokufaka okujwayelekile. Izici ezivame ukuchazwa ngokuvamile zisetshenziselwa ukurekhoda uhlelo lwe-TV ekhadini le-flash noma ukudlala amafayela alalelwayo namavidiyo alondolozwe ku-flash drive.

Umthelela omkhulu kumanani unesakhiwo se-CI esakhelwe ukuxhuma ikhadi lokufinyelela elinemibandela, elikuvumela ukubuka iziteshi ezikhokhelwayo. Namuhla, cishe zonke iziteshi ezisakazwa ensimini yeRussia zikhululekile, kodwa esikhathini esizayo kungenzeka ukuthi lokhu kungasiza kakhulu.

Izici ezengeziwe

Umamukeli angaba nenani elikhulu lemisebenzi eyakhelwe ngaphakathi, abanikazi abangacabangi. Okuthandwa kakhulu yikhono "lokuyeka isikhathi" - Isikhathi sesikhathi. Kodwa ithuba elinjalo liyiqhinga elenza ukuthi isamukeli se-DVB-T2 ye-digital yabiza kakhulu.

Iqiniso liwukuthi lo msebenzi utholakala kuphela kumamukeli we-satellite. "Ama-antenna" amadivaysi, lapho "ukuyeka isikhathi" ukudubula kwesikrini kuthathwa futhi umsindo uvaliwe, kodwa ukudlulisa ngokwayo kuyaqhubeka nokuhamba.

Esinye isici esidumile - umhlahlandlela we-TV, okuvumela ukuba ubuke umhlahlandlela wohlelo, usebenza kangcono kangcono. Ukusebenza kwalo kuxhomeke esiteshini esithile. Ukusetha i-timer ukunika amandla ngokuzenzakalelayo noma ukukhubaza isiteshi yimisebenzi eyengeziwe eyengeziwe eyenza nakanjani.

Ixhuma i-console ku-TV yakho

Ungakwazi ukuxhuma ibhokisi le-digital set-top ngezindlela ezimbili. Uma i-antenna yakho inekhebula le-coaxial elenziwe ngomumo, bese umane ulifake ku-receiver ye-DVB-T2 yedijithali, bese uqala ukulungisa iziteshi. Kwezinye izimo, kufanele uthenge ikhebula le-coaxial ngokwakho, ikakhulukazi uma i-antenna yakho ine-amplifier eyakhelwe ngaphakathi. Kulolu cala, uzodinga futhi isixhumi se-f-type connector. Ukuze uyifake kwikhebula, kuyadingeka ukusika ungqimba wokuqhafaza, usakaze i-foil yensimbi kanye nemifino eceleni kwendwangu bese ufika emgodini wethusi. Khona-ke ungakwazi ukugoqa isixhumi ku-receiver.

Izindlela zokuxhuma i-TV ku-console ingaphezulu kakhulu. Ungasebenzisa "ama-tulips", i-RCA, i-SCART noma i-HDMI. Ngeke kube khona ubunzima lapha. Ngemuva kokuhlanganisa amadivayisi, ihlala kuphela ukulungisa i-digital receiver DVB-T2 ngendlela efanayo njengoba ukusesha kwesiteshi ku-TV kulungiswa.

Amamodeli webhajethi

Izindleko zezinhlobo zebhajethi ziphakathi kwama-ruble ayizinkulungwane ezingu-1-2. Ukusebenza kwabo kwanele ukubukwa ngokukhululekile kwemibukiso ye-TV. Ivula uhlu lwethu lwe-VVK SMP240HDT2 olubiza ama-ruble angu-1,5 ayizinkulungwane. Kukhona isikhombimsebenzisi se-USB esakhelwe ngaphakathi, okwenza kube lula ukurekhoda izinhlelo ze-TV nokubuka amafayela abezindaba. Isixhumi se-HDMI singasetshenziswa ukuxhuma i-TV ene-HD. Phakathi kwamaminithi, kufanele kuqaphele ukusabela okubi ekulawuleni okude futhi okungahambi kahle kwemilayezo enezibonakaliso zokudela kwe-TV. Isiqalo D-COLOR DC1302 sinemisebenzi efanayo eyakhelwe njengommeleli wangaphambilini. Kodwa lo mamukeli wedijithali we-DVB-T2 uthembekile kakhulu kumsebenzisi - uyaphendula kangcono kwimilayezo yesilawuli kude. Abathengi baphinde baphawula inkampani yensimbi yesitayela enokufakwa kwepulasitiki. Phakathi kwezinselele - iziteshi ezishintshayo.

I-receiver ye-Oriel 963 ingasebenzi kakhulu kunabamele abengaphambili - ayikho i-HDMI. Abasebenzisi bakuthanda ngokukhethekile ukusethwa kwesiteshi - kungenziwa ngokuchofoza okumbalwa nje. Kodwa imenyu ayiyona elula kakhulu futhi iyaqondakala - kuyodingeka uyihlangabeze.

Abamele Abakhethekile

Ikakhulukazi lezi zithuthukisi ezinikezwe ngezansi zingabizwa ezinye izici ezingekho ezitholakalayo kumamodeli asevele achazwe. Ngaphezu kwalokho, izindleko zala madivayisi nazo azidluli ama-ruble ayizinkulungwane ezimbili.

I-SUPRA SDT-94 - isamukeli sedijithali DVB-T2 enokusekelwa kwe-HD nesimo esibonakalayo se-USB sokubuka idatha kusuka kumakhadi e-flash. Ngokuhlukile, abasebenzisi babone ukwamukelwa okuhle kwempawu, kungakhathaliseki uhlobo lwe-antenna oluxhunyiwe, kanye nokuseshwa kwesiteshi esilula. Isici esikhethekile ngumsebenzi wokulawula wabazali, ovimbela iziteshi ezithile ngaphambi kokufaka iphasiwedi. Ukungalungi okuyinhloko ukwehla kwekhwalithi yesithombe uma kuxhunywe ngokukhipha okuhlanganisiwe.

Imodeli eyengeziwe yokuqala yiRolsen RDB-532. I-receiver ihlanganisa ubukhulu be-compact kanye nokusetshenziswa kwamandla aphansi, okuvumela ukuthi isetshenziswe njengesiphathi esithintekayo noma sezimoto. Ukuze wenze lokhu, udinga kuphela ukuthenga intambo yamandla. Awunawo umxhuma we-HDMI, kodwa ikhono lokudlala le-multimedia ligcinwe. Lesi samukeli se- TV DVB-T2 izimangalo ezivela kubasebenzisi abanakho. Ukusebenza kwalo ngokugcwele kuhambelana nentengo.

Abamukeli be-SMART

Leli qembu lamadivayisi libiza kakhulu. Kodwa-ke, zisebenza kahle futhi zikwazi ukuhamba ku-inthanethi, futhi nazo ezinye izici eziningi. Umamukeli we-4K we-Dune HD, ngaphezu kokubukela iziteshi ze-TV ngokuqondile kwi-inthanethi kwifomethi ye-4K, ukudlala kwe-multimedia, ukurekhoda kwevidiyo, ukufinyelela kwenethiwekhi yomhlaba wonke, imenyu elula nemisebenzi esele ichazwe kwamanye amamodeli, ingasetshenziswa njengendawo yokufinyelela engenazintambo kwi-Wi- Fi. Ngesikhathi esifanayo ukuhlinzeka ngesivinini esikhulu kubasebenzisi abaningana ngesikhathi esisodwa. Ezimayini, kufanele kuqashelwe intengo ephakeme - cishe ama-ruble ayizinkulungwane ezingu-24.

I-IconBIT XDS94K iyisamukeli se-digital DVB-T2 esisezingeni elincane. Kodwa kubiza izikhathi ezingaphansi kuka-4 kunommeleli wangaphambilini. Ngaphezu kokuphequlula izinsiza ze-intanethi, ukudlala kwe-multimedia, idivayisi ingasetshenziswa ukwenza amakholi wevidiyo, udinga kuphela ukuthenga ikhamera yewebhu. Ngaphezu komamukeli, ungaxhuma igundane nekhibhodi. Phakathi kwama-minuses kukhona ukulanda okude isikhathi eside kweziteshi.
