Indlela yokuxhuma i-TV kumamukeli? Indlela yokuxhuma umamukeli kumabonakude amabili?

Umbuzo wendlela yokuxhuma i-TV kumamukeli uvela ngokuyinhloko kulabo benzi bezandla abafuna ukwenza le nqubo ngokwabo. Uma kukhona uxhumano olujwayelekile oluvela enkampanini yomhlinzeki, kuhlale kunomchwepheshe omele inkonzo yokufaka yale nkampani futhi enze yonke imisebenzi edingekayo ekuxhumaneni. Futhi emva kwayo yonke imisebenzi eyenziwa nguye, iklayenti ithola uhlelo olulungile oluvumela ukubuka ividiyo, futhi akanayo imibuzo mayelana nokuthi uhlelo luzohlangana kanjani, kodwa luvele luyixhase. Kulesi sihloko, sizobuka ukuthi yiziphi izinhlobo zamamukeli ezitholakalayo nokuthi yiziphi izimo ezixhunyiwe ku-TV.

Izinhlobo

Okwamanje, kunezinhlobo ezintathu eziyinhloko zamamukeli. Ngamunye wabo unqunywe ngenhloso yedivayisi ekulawuleni kwevidiyo ethile kanye nesistimu yokuguqula. Ngakho-ke, impendulo yombuzo wokuthi ungaxhuma kanjani i-TV kumamukeli izoxhomeke kakhulu kunhlobo nendawo yesistimu yevidiyo. Manje ake sibheke ukuthi yiziphi izinhlobo zamadivaysi anjalo akhona kanye nezici zabo zokusebenza. Izinhlobo eziyinhloko:

• I-TV yesathelayithi.
• Ngethelevishini yekhebula.
• Isikhungo sevidiyo sasekhaya.

Uma sikhuluma ngenjongo yokusebenza yale divayisi, kufanele sikhulume imisebenzi eminingana ehlanganiswa nohlobo oluthile lomamukeli. Iyini le misebenzi?

• Ukushintsha imvamisa yenkampani yenethiwekhi kanye nokuhlelwa kwezimpawu zesignali ephezulu kakhulu.
• Shintsha isignali yevidiyo kusuka emithonjeni ehlukene.
• Ukuphakanyiswa kwesignali yomsindo kumandla adingekayo.

Manje ake sibheke ukuthi iyiphi yale misebenzi esetshenziswa kuhlobo oluthile lwedivayisi.

Umamukeli we-TV ye-satellite

Lokhu kungenye yezinhlobo ezivame kakhulu. Esinye sezici zayo eziyinhloko iyinani elingathengi.

Umbuzo wendlela yokuxhuma i-TV kumamukeli wethelevishini ye-satellite ilula kakhulu. Futhi lokhu kungenxa yokuthi umsebenzi oyinhloko wedivayisi enjalo ukuguqula isignali ephezulu-imvamisa evela kwisiphequluli se-satellite antenna, esinciphisa imvamisa yesignali izikhathi eziningana futhi ikulethe kufika ku-1-2 GHz. Ngemuva kwalokho, isamukeli se-satellite sinquma lesi siginali futhi sidlulisela isignali yevidiyo ephansi edivaysi yokudlala efana ne-TV noma iphrojekthi yevidiyo. Inombolo yezixhumi zokuxhuma idivayisi yokudlala ividiyo incike eklasini lomamukeli futhi ingaba nezinhlobo eziningana. Elula kakhulu isethi yezixhumanisi ezifana "ne-tulip".

Ngethelevishini yekhebula

Umamukeli weklayenti yethebula ithelevishini akafani kakhulu nomunye umlingani we satellite. Kuyinto idivayisi efanayo, ngesethi efanayo yemisebenzi, nje isethi yamasethingi encane. Uyini umehluko phakathi kwala madivaysi amabili?

Ngokungafani nedivayisi yesathelayithi, ikhebula alixhunyiwe ku-converter yesignali ephezulu, kodwa kusukela ekushintsheni kwekhebula. Futhi le divayisi ayinayo i-satellite ehlukene. Lesi samukeli sibhalwa kumvamisa wokuthwala womhlinzeki, okudlulisela isignali ephezulu-yevaysi ngesethi yamashaneli ekhebula kusukela ekushintsheni kumthengi. Ikhwalithi nenombolo yezixhumanisi zokuxhuma i-cable receiver kuya ku-TV ayifani neze satellite.

Isikhungo sevidiyo sasekhaya

Uhlobo oluhlukile ngokuphelele lomamukeli yidivayisi eyenzelwe ukusebenza njengengxenye yesikhungo sevidiyo sasekhaya. Kulula ukucacisa ngokubukeka, uma uhambisa futhi ubona kusuka ohlangothini olungemuva.

Le divayisi inenani elikhulu kakhulu lezixhumi ezisemuva. Kungani kuningi kangaka? Umsebenzi oyinhloko wale divayisi ukuguqula imithombo eminingi yevidiyo yokufakwayo nama-audio kumadivaysi amaningana wokudlala ividiyo. Ngakho-ke, umbuzo wendlela yokuxhuma umamukeli ku-TV uhambelana kakhulu, ngoba leyo divayisi inezinombolo zokuxhumeka kokuxhuma ama-TV amaningana noma amanye amadivaysi. Lolu hlobo lwedivayisi aluguquli ividiyo, kodwa luvele lushintshe ividiyo ephansi. Ngaphezu kwalokho, umsebenzi obalulekile walowo divayisi ukukhuliswa nokushintsha kwesignali yomsindo evela emithonjeni ehlukene.

Izinhlobo zezixhumi zokuxhumana

Ukuze uqonde ukuthi yiziphi izinhlobo zezixhumi ezisetshenziselwa ukuxhuma umamukeli ku-TV, kubalulekile ukuthola ukuthi yiziphi izinhlobo zezixhumi ezisetshenziswa kulolu hlobo lwenqubo. Kuye ngesigaba se-TV nesigaba somamukeli, izixhumi zihlukaniswe ngezigaba ezimbili:

• Izixhumanisi zokuxhuma isignali yevidiyo.
• Izixhumanisi zokuxhuma isignali yomsindo.

Uma ubuka isithombe sesokunxele samukeli wesathelayithi, ungabona zonke izinhlobo zalezi zixhumanisi.

Uma uphendula umbuzo mayelana nokuthi ungaxhuma kanjani i-TV kumamukeli ngekhebula levidiyo, kufanele kuthiwa ukuthi izixhumi kule divayisi zingaba izinhlobo ezintathu: i-composite, i-S-Video ne-HDMI. Futhi lo mdlalo udlulisa ividiyo kanye nomsindo ngesikhathi esisodwa. Ukuze uthole impendulo yombuzo mayelana nokuthi ungaxhuma kanjani owamukelayo ku-TV ngekhebula lomsindo, kufanele wazi ukuthi izinhlobo zoxhumano zingaba ezimbili: okufanayo, njengamavidiyo, ne-fiber. Yiqiniso, ikhwalithi ezwakalayo yokuxhumanisa kwe-fiber optic izoba ngaphezulu kakhulu.

Imidwebo yokuxhumana

Cabanga ukuthi ungaxhuma kanjani i-TV ngokusebenzisa umamukeli, isibonelo, idivayisi yekhebula enezixhumi ezihlanganisiwe. Futhi ngokuvamile umbuzo wokuxhuma i-TV eyodwa isethi ixazululwe. Uhlelo loxhumano olunjalo lungabheka into enjengale.

Kulesi simo, umbala wombala wezixhumanisi kuzosiza umsebenzisi wesistimu enjalo ukuthi angaphambuki ekuqineni kokuxhumeka. Umbuzo wendlela yokuxhuma i-TV yesibili kumamukeli ngokuvamile uvamile kakhulu, kepha ngezinye izikhathi kudinga impendulo. Lokhu kuvela nini?

Ngokuyinhloko, ezimweni lapho ufuna ukuhlela ukubuka ividiyo efanayo emakamelweni ahlukene. Kungani, uma uxhuma umamukeli kuma-TV amabili, ingabe ividiyo izodlalwa efanayo? Nakuba izamukeli zinemiphumela eminingana, isignali esithunyelwa kubo iyafana. Ngakho-ke, abamukeli abaningi kudingeka babheke izinhlelo eziningana ngesikhathi esisodwa.

Ukwamukela okhethekile kumhlinzeki othile

Ngokuvamile, abanye abahlinzeki be-TV be-satellite banikeza isethi yokuxhumana yokuxhumana esiteshini sabo. Isibonelo somhlinzeki onjalo ngu- "Tricolor". Ngokuvamile inikeza idivayisi yayo, ikhonyiwe ngaphansi kwe-satellite yomhlinzeki. Indlela yokuxhuma umamukeli "Tricolor" ku-TV? Uhlelo lokuxhumana alufani ne-satellite evamile, okukhulunywe ngaye ekuqaleni.
