Liyini ibhokisi le-TV yedijithali, indlela yokuxhuma nokusebenzisa isamukeli se-DVB T2

Ama-TV amaningi esimanje afakwe ishuna eyakhelwe ngaphakathi ekuvumela ukuthi uthathe isignali yekhwalithi ephezulu. Uma usebenzisa i-TV ngaphandle kwalokhu kusebenza, bese ubuka amamuvi nezinhlelo ze-TV ezinesithombe esihle kakhulu nomsindo wekhwalithi ephezulu, ungathenga isisetshenziswa esikhethekile esibizwa nge-digital TV set-top box (ishuna yedijithali, isamukeli sedijithali).

Liyini ibhokisi le-TV yedijithali

Ibhokisi lokusetha phezulu kwe-TV yedijithali iyisisetshenziswa esincane esikuvumela ukuthi uthwebule isignali yomsakazo wedijithali okungenzeka ukuthi idluliselwe ku-TV yedijithali. Lolu cingo lubizwa nangokuthi ishuna yedijithali, umamukeli noma idekhoda. Igama elisemthethweni lamazwe ngamazwe lezinga elithi
DVB-T2. Ibhokisi le-TV yedijithali lithuthukisa isithombe nekhwalithi yomsindo. Ngemuva kokuxhuma, uzothola ukufinyelela kwamahhala kuzo zonke iziteshi ezinkulu zesifunda nezesifunda (cishe izingcezu eziyi-15-20). Ukwengeza, ungathenga ukufinyelela eziteshini zekhebula ezivaliwe kubahlinzeki bedijithali, futhi izinkampani ezifana ne-Beeline, i-MTS nezinye zisebenza njengabahlinzeki abakhulu namuhla. Ibhokisi le-digital set-top lixhuma ku-TV ukukhipha isignali kanye nothi ukuze lwamukele isignali. Amabhokisi amaningi aphezulu afakwe i-amplifier ukuqinisekisa ukwamukela okungaphazamiseki kwesignali yedijithali yekhwalithi ephezulu. [textbox id=’alert’]Naka! Ngemva kokuxhuma, udinga ukulungisa idivayisi, futhi amadivayisi amaningi esimanje afakwe ngosesho lwesignali oluzenzakalelayo nesistimu yokushuna, eyenza ukusebenza kweshuna kube lula.[/stextbox]

Zisetshenziselwa ini izemukeli zikamabonakude zedijithali?

Amashuni amaningi esimanje anezici ezilandelayo:

• Ukwamukela nokuqopha isignali yomsakazo wedijithali ye-DVB-T2.
• Ukuba khona kwezixhumi ze-USB zokuxhuma amadivaysi angaphandle (eqinisweni, uma izixhumi ezinjalo zikhona, ibhokisi le-set-top lingasetshenziswa njengesidlali semidiya).
• Ukwamukela nokuchazwa kwesignali yesathelayithi ye-DVB-S2.
• Ukucindezelwa nokugcinwa kwevidiyo ngefomethi ye-MPEG-4.
• Ukusekelwa kwevidiyo enencazelo ephezulu (1080p nangaphezulu).
• Ikhono lokuxhuma ku-inthanethi usebenzisa okokufaka kwe-LAN.
• Ukuba khona kwesiphequluli esakhelwe ngaphakathi.
• Ukudlala ividiyo enemicu eminingi.
• Ikhono lokurekhoda nokugcina isignali (ukurekhoda kungenziwa kokubili kuma-flash drive akhiphekayo kanye nama-hard drive alungisiwe).
• Dala umsindo ozungezile onencazelo ephezulu.
• Ikhono lokulawula ishuna usebenzisa isilawuli kude.

Ama-TV anebhokisi le-set-top eyakhelwe ngaphakathi

Omabonakude abaningi besimanje baneshuna eyakhelwe ngaphakathi yokuthola umabonakude wedijithali, osakaza ngokuzenzakalelayo isignali yedijithali. Isimiso sokusebenza kanye nezakhiwo zobuchwepheshe zamadivayisi anjalo azihlukile kokunamathiselwe okukhishwayo. Wonke amashuna akhelwe ngaphakathi anikeza ukufinyelela kwamahhala kuzo zonke iziteshi ezinkulu zikazwelonke nezesifunda, futhi ukuze ufinyelele iziteshi zekhebula, udinga ukuthenga nokufaka ikhadi le-SMART endaweni ekhethekile. Namuhla, cishe wonke ama-TV edijithali anebhokisi le-set-top eyakhelwe ngaphakathi, futhi abakhiqizi be-TV abadumile kakhulu izinkampani ezifana ne-LG, Samsung, Philips, njalonjalo. [textbox id=’alert’]Naka! Ngaphezu kwezinga lokusakaza lesimanje le-DVB-T2, kukhona nezinga le-DVB-T eliphelelwe yisikhathi. Namuhla ayisasetshenziswa, nokho, amanye amathelevishini angase afakwe nebhokisi elakhelwe ngaphakathi le-DVB-T set-top. Akunconywa ukuthenga lawo ma-TV, ngoba awakwazi ukukhiqiza kabusha isignali ye-DVB-T2.[/stextbox]

Abakhiqizi nabahlinzeki abadumile: indlela yokukhetha ibhokisi le-digital set-top box le-TV

Manje ake sibheke amabhokisi aphezulu edijithali angatholakala emakethe yaseRussia:

1. Idatha ye – DC1002HD Idivayisi ibamba isignali kahle, inemenyu elula eyakhelwe ngaphakathi futhi izindleko ziphansi kunezimbangi. Okubi okuyinhloko ukuthi idivayisi ayisebenzi kahle ngomsindo futhi ijwayele ukushisa ngokweqile. Abanye abasebenzisi bakhononda ngomklamo ongemuhle wesilawuli kude, nakuba lokhu kungeyona into embi kakhulu. Ngokuvamile, idivayisi ifaneleka kahle kuma-cottage ehlobo namakhishi, kuyilapho kunganconywa ukuxhuma i-TV eyinhloko kuyo endlini.
2. I-TF-DVBT201 . Idivayisi ithatha amasignali kahle kokubili edolobheni nasemaphandleni, futhi idivayisi ngokwayo ayibizi kakhulu. Kukhona izimbobo ze-USB ezimbalwa, ngakho-ke leli bhokisi lokumisa phezulu lingasetshenziswa njengesidlali semidiya. Kungase kushise kakhulu ngesikhathi sokusetshenziswa isikhathi eside, kodwa le nkinga ingaxazululwa ngokuhlubula ifilimu yokuzivikela. Iyancipha kancane uma ivuliwe. Idivayisi ingaba efanelekile kumakotishi asehlobo namakhishi; ingaxhunywa ku-TV eyinhloko.
3. I-DSR-10 . Le divayisi ingabizwa ngokuthi isiqalo sesigaba somnotho esingcono kakhulu. Izinzuzo eziyinhloko – ibamba kahle isignali, ukusebenza okucebile, ukuba khona kwenani elikhulu lezixhumi, intengo ephansi. Ububi obuyinhloko akuyona imenyu esebenziseka kalula kanye ne-adaptha yomsindo ebuthakathaka uma kuqhathaniswa. Le modeli ingafakwa kokubili ekhaya nasezweni.
4. Idatha ye – SMP136HDT2 Isici esiyinhloko sale divayisi yiqiniso lokuthi ibamba ngokuphelele isignali ebuthakathaka. Le modeli inesistimu yokupholisa enamandla futhi ayibizi kakhulu. Kodwa-ke, futhi inezihibe – izixhumi ezimbalwa, imenyu engalungile, nesilawuli kude esingelula neze. Le divayisi ithatha isignali yomsakazo kahle, ngakho ilungele idolobhana nedolobhana, ezitholakala kude kakhulu nabaphindayo. Kodwa endabeni yedolobha, kunconywa ukunikeza okuthandayo kwezinye iziqalo.
5. I-SMP242HDT2. Idivayisi ibamba isignali kahle, inezixhumi eziningi futhi ixhumeka kalula ku-TV. Leli bhokisi le-set-top lihlanganisa izinhlelo eziningi zokurekhoda nokudlala ividiyo. Ububi obuyinhloko intengo ephakeme kakhulu yedivayisi kanye nemenyu engalungile kakhulu yokusetha. Le divayisi ifaneleka kahle ekhaya, kuyilapho ukunikeza kungcono ukuthenga idivayisi elula.
6. I-M8 Android TV Box . Eqinisweni, le divayisi ayilona ibhokisi lokubeka phezulu njengedivaysi eyinkimbinkimbi ye-multimedia. Izici eziyinhloko – kunezixhumi eziningi zokuxhuma amadivayisi angaphandle, kukhona ithuba lokuxhumana okuqondile kwi-Inthanethi, kukhona isiphequluli sokuphequlula amakhasi e-inthanethi, kukhona ukusebenza okuthuthukisiwe kokurekhoda nokudlala amavidiyo, njalonjalo. Ububi obuyinhloko intengo ephakeme kakhulu yedivayisi. Leli bhokisi lokusetha phezulu liyanconywa ukuthi lixhunywe ku-TV eyinhloko endlini.

Ukusebenzisa isamukeli sedijithali ezweni

Ukusetshenziswa kwebhokisi le-digital set-top kungalungiswa kokubili edolobheni nasezweni, noma kunjalo, ngaphambi kokuthenga idivayisi, kuhle ukuhlola ikhwalithi yesiginali yedijithali. Ngenhlanhla, kuzo zonke izifunda ezinkulu zaseCentral Russia, ikhwalithi yesiginali emadolobheni amaningi amancane namadolobhana inhle, ngakho-ke ukuthenga ishuna yedijithali kunengqondo. Ngokuvamile, ukusakazwa kubukeka kanjena:

1. Umbhoshongo we-TV oyinhloko wesifunda usakaza isignali yamandla aphezulu.
2. Kude nombhoshongo, kufakwe iziphindaphinda ezithatha futhi zikhulise isignali ebuthakathaka.
3. Isignali ekhulisiwe ingabanjwa kusetshenziswa ibhokisi le-digital set-top box. Ngokuzenzakalelayo, umsebenzisi uzokwazi ukufinyelela eziteshini ze-TV ezingaba ngu-20, futhi ngenkokhelo eyengeziwe, angaxhuma iziteshi zekhebula kumhlinzeki wendawo.
4. Ukuze ubambe isignali ezweni, kunconywa ukuthi ufake i-antenna khona kanye endlini. Uma isignali ibuthakathaka ngokwanele, khona-ke kunengqondo ukubeka uthi ngaphandle ophahleni lwendlu.
5. Ukwengeza, kunengqondo ukufaka i-amplifier ukuze uthole ukusakaza okuzinzile.
6. Ngemva kokufaka i-antenna, udinga ukwelula ikhebula ebhokisini elibekwe phezulu.

Udinga futhi ukucabanga ngezintambo zesignali ezifanele:

1. Uma usebenzisa amashuna amadala angasebenza ngokusakaza okukodwa kuphela, kuzomele ufake ishuna ku-TV ngayinye. Uma kungenjalo, zonke izakhamuzi kuzodingeka zibukele isiteshi esisodwa kuwo wonke ama-TV.
2. Le nkinga ingaphinde ixazululwe ngokuthenga idivayisi ebiza kakhulu evumela ukuthi isignali ihlukaniswe ibe yimifudlana eminingana ezosebenza ngokuzimela. Ngenhlanhla, namuhla amadivaysi anemicu eminingi ashibhile ngokwanele kangangokuthi ukuwathenga ngeke kube umthwalo osindayo wezezimali kuwe.

Ngiyathokoza ukwazi! Uma i-tuner izoma endlini yezwe edolobhaneni elikude nedolobha, lapho-ke uthenga, nikeza okuthandayo kumamodeli abamba futhi achaze kahle isignali.

Ibhokisi le-TV yedijithali liyadingeka ukuze ubuke imidlalo ye-TV namamuvi ngekhwalithi ephezulu. I-set-top box inikeza ukufinyelela kwamahhala kuzo zonke iziteshi ezinkulu ze-TV, futhi ukuze uxhume amashaneli ekhebula, udinga ukuxhumana nomhlinzeki wakho kamabonakude wedijithali. Amamodeli ayinhloko wamabhokisi abekwe phezulu yi-DC1002HD, DSR-10, SMP136HDT2 namanye.
