Yintoni iTV yedijithali iseti-phezulu ibhokisi, indlela yokudibanisa nokusebenzisa DVB T2 umamkeli

IiTV ezininzi zanamhlanje zixhotyiswe nge-tuner eyakhelwe-ngaphakathi evumela ukuba uthathe uphawu oluphezulu. Ukuba usebenzisa iTV ngaphandle kwalo msebenzi, ngoko ukubukela iimuvi kunye nemiboniso yeTV ngomfanekiso obalaseleyo kunye nesandi esiphakamileyo, unokuthenga isixhobo esikhethekileyo esibizwa ngokuba yi-digital TV set-top box (i-digital tuner, i-digital receiver).

Yintoni iTV yedijithali iseti-phezulu ibhokisi

I-TV yedijithali iseti-phezulu ibhokisi sisixhobo esincinci esikuvumela ukuba ubambe isiginali yerediyo yedijithali kunye nokwenzeka kokudluliselwa kwayo kwiTV yedijithali. Esi sixhobo sikwabizwa ngokuba sisixhobo sokuhambisa idijithali, umamkeli okanye idikhowuda. Igama elisemthethweni lamazwe ngamazwe lomgangatho yi -DVB-T2. Ibhokisi yedijithali yeTV iphucula umfanekiso kunye nomgangatho wesandi. Emva kokudibanisa, uya kufumana ukufikelela kwamahhala kuwo onke amajelo aseburhulumenteni kunye neengingqi (malunga neziqwenga ze-15-20). Ukongeza, unokuthenga ukufikelela kwiitshaneli zekhebula ezivaliweyo kubaboneleli bedijithali, kunye neenkampani ezinjengeBeeline, iMTS kunye nabanye zisebenza njengababoneleli abaphambili namhlanje. Ibhokisi yokusetha yedijithali iqhagamshela kwi-TV ukuze ikhuphe isignali kunye ne-eriyali ukufumana isignali. Iibhokisi ezininzi ezibekwe phezulu zixhotyiswe nge-amplifier ukuqinisekisa ukwamkelwa okungaphazamisekiyo kwesignali yedijithali ephezulu. [textbox id=’alert’]Mamela! Emva kokudibanisa, kufuneka uqwalasele isixhobo, kwaye izixhobo ezininzi zanamhlanje zixhotyiswe ngokhangelo lomqondiso oluzenzekelayo kunye nenkqubo yokulungisa, eyenza lula ukusebenza kwe-tuner.[/stextbox]

Zisetyenziselwa ntoni izamkeli zikamabonwakude zedijithali?

Uninzi lweetoni zangoku zinezi mpawu zilandelayo:

• Ukufumana kunye nokuguqula i-DVB-T2 isignali yedijithali yerediyo.
• Ubukho bezixhumi ze-USB zokudibanisa izixhobo zangaphandle (eqinisweni, ukuba ezo ziqhagamshelo zikhoyo, ibhokisi yokumisela ingasetyenziselwa njengomdlali weendaba).
• Ukwamkelwa kunye nokutolikwa komqondiso wesathelayithi ye-DVB-S2.
• Uxinzelelo kunye nokugcinwa kwevidiyo kwifomethi yeMPEG-4.
• Inkxaso yevidiyo yenkcazo ephezulu (1080p nangaphezulu).
• Ukukwazi ukuqhagamshela kwi-Intanethi usebenzisa igalelo le-LAN.
• Ubukho besiphequluli esakhelwe ngaphakathi.
• Ukudlala ividiyo enemisonto emininzi.
• Ukukwazi ukurekhoda kunye nokugcina umqondiso (ukurekhoda kunokuqhutywa zombini kwi-flash drives ekhutshwayo kunye ne-fixed hard drives).
• Yenza isandi esijikelezileyo senkcazo ephezulu.
• Ukukwazi ukulawula i-tuner usebenzisa isilawuli kude.

IiTV ezinebhokisi eyakhelwe-ngaphakathi yokuseta

Oomabonakude abaninzi banamhlanje banesixhobo esakhelwe ngaphakathi sokufumana umabonakude wedijithali, osasaza ngokuzenzekelayo umqondiso wedijithali. Umgaqo wokusebenza kunye neempawu zobugcisa zezixhobo ezinjalo azifani neziqhotyoshelo ezikhutshwayo. Zonke ii-tuners ezakhelwe ngaphakathi zibonelela ngokufikelela ngokukhululekileyo kuzo zonke iziteshi ezinkulu zelizwe kunye nezengingqi, kunye nokufikelela kwiitshaneli zentambo, kufuneka uthenge kwaye ufake ikhadi le-SMART kwi-slot ekhethekileyo. Namhlanje, phantse zonke iiTV zedijithali zinebhokisi eyakhelwe-ngaphakathi, kwaye abenzi beTV abadumileyo ziinkampani ezifana ne-LG, Samsung, Philips, njalo njalo. [textbox id=’alert’]Mamela! Ukongeza kumgangatho wosasazo we-DVB-T2 wale mihla, kukwakho nomgangatho ophelelwe lixesha weDVB-T. Namhlanje ayisasetyenziswa, nangona kunjalo, ezinye iithelevishini zinokuxhotyiswa ngebhokisi ye-DVB-T eyakhelwe-ngaphakathi. Akukhuthazwa ukuthenga iiTV ezinjalo, kuba azikwazi ukuvelisa kwakhona uphawu lwe-DVB-T2.[/stextbox]

Ukusebenzisa isamkeli sedijithali elizweni

Ukusetyenziswa kwebhokisi ye-digital set-top box inokulungiswa kokubili kwisixeko nakwilizwe, nangona kunjalo, ngaphambi kokuthenga isixhobo, kuyacetyiswa ukuba uhlolisise umgangatho wesiginali yedijithali. Ngethamsanqa, kuyo yonke imimandla emikhulu ye-Central Russia, umgangatho wesignali kwiidolophu ezincinci kunye needolophana zilungile, ngoko ukuthenga i-tuner yedijithali kukho ingqiqo. Ngokubanzi, usasazo lukhangeleka ngolu hlobo:

1. Eyona ndawo iphambili yeTV yengingqi isasaza umqondiso wamandla aphezulu.
2. Kude nenqaba, iireyitha zifakiwe ezithatha kwaye zikhulise umqondiso obuthathaka.
3. Isignali eyandisiweyo inokubanjwa usebenzisa i-digital set-top box. Ngokungagqibekanga, umsebenzisi uya kuba nokufikelela kumajelo eTV angama-20, kwaye ngentlawulo eyongezelelweyo, unokudibanisa iziteshi zekhebula kumnikezeli wendawo.
4. Ukubamba umqondiso kwilizwe, kucetyiswa ukuba ufake i-antenna ekunene endlwini. Ukuba umqondiso ubuthathaka ngokwaneleyo, ngoko kunengqiqo ukubeka i-eriyali ngaphandle kophahla lwendlu.
5. Ukongezelela, kunengqiqo ukufaka i-amplifier ukufumana usasazo oluzinzileyo.
6. Emva kokufaka i-antenna, kufuneka wolule ikhebula kwibhokisi yokumisela.

Kufuneka ucinge kwakhona malunga nocingo olufanelekileyo lwesignali:

1. Ukuba usebenzisa iishuneli ezindala ezinokusebenza kuphela ngomjelo omnye, ngoko kufuneka ufakele i-tuner kwi-TV nganye. Ngaphandle koko, bonke abahlali kuya kufuneka babukele isitishi esinye kuzo zonke iiTV.
2. Le ngxaki ingasombululwa ngokuthenga isixhobo esibiza kakhulu esivumela ukuba isignali ihlulwe ibe yimijelo emininzi eya kusebenza ngokuzimeleyo. Ngethamsanqa, namhlanje izixhobo ezinemisonto emininzi zitshiphu ngokwaneleyo kangangokuba ukuzithenga akuyi kuba ngumthwalo onzima wemali kuwe.

Kuhle ukwazi! Ukuba i-tuner iya kuma kwindlu yelizwe kwidolophana ekude nesixeko, ngoko xa uthenga, nika okuthandayo kwiimodeli ezibamba kwaye zichaze kakuhle umqondiso.

I-TV yedijithali iseti-phezulu ibhokisi iyafuneka ukuze ubukele iinkqubo zikamabonakude kunye neemuvi ezikumgangatho ophezulu.
