Ungawaxhuma kanjani ama-TV amabili kusuka kwesinye isamukeli se-Tricolor – esisha nesidala [/ amazwibela]
Izinketho zokusakaza
Kunezinhlobo ezimbili zokudluliswa kokusakaza kumsebenzisi: okufakwe isibuko nokuhlukanisiwe. Ukwenza isibuko kusho ukudlulisela isithombe esifanayo kwamanye amadivaysi axhunyiwe. Le ndlela ayidingi ukusetshenziswa kwemishini eyengeziwe ngendlela yokwamukela i-TV ngayinye. Kodwa le ndlela ibacasula kakhulu ababukeli abangenawo umshini wokushuna, njengoba, eqinisweni, yilo onesilawulikude esilawula ukubukwa, futhi abanye bancishwa ithuba elinjalo. Mayelana nohlobo oluhlukile lokudlulisela, kusho igama layo. Ngalokhu kuxhumana, isithombe ngasinye sisakazwa kudivayisi ngayinye. Kuzwakala kukuhle, kodwa yini inkinga? Kulele eqinisweni lokuthi kulolu hlobo lokusakaza kuyadingeka ukuthenga imishini eyengeziwe ye-TV ngayinye futhi ngandlela-thile uhlukanise isignali engenayo emifuleni eminingana ephumayo.
Amasignali amabili afanayo nge-wi fi kanye nokupheya okusontekile akuvumela ukuthi uxhume i-Tricolor kuma-TV amabili ukusuka kumamukeli oyedwa [/ amazwibela]
Ungawaxhuma kanjani ama-TV amabili kwesinye isamukeli se-Tricolor TV?
Kunezindlela ezimbalwa zokudlulisa isignali eyinhloko isuka esitsheni sesathelayithi iye kumadivayisi asizayo:
- usebenzisa isixhumi esiphumayo esisisetshenziswa sokuqala esamukelayo;
- sebenzisa isihlukanisi esikhethekile (isihlukanisi) esihlukanisa isignali engenayo ibe yimifudlana eminingana;
- sebenzisa iziguquli ezinemiphumela eyengeziwe.

Yiziphi izisetshenziswa ezengeziwe ezidingekayo?
Isethi ejwayelekile ye-Tricolor TV ayinikezi isiguquli nesihlukanisi, ngakho-ke kuzodingeka uzifunele futhi uzithengele lesi sisetshenziswa. Nalapha futhi, kukhona ubuqili. [i-id yamagama-ncazo = “okunamathiselwe_3544″ align=”aligncenter” wide=”1000″]
Umgomo wokusebenza kwesiguquli se-antenna kokuphumayo okubili[/caption]
Akufanele neze ukhethe isiguquli esinenombolo eyisipele yemiphumela, ngisho noma ungahlela ukuxhuma izamukeli ezengeziwe ngokuzayo. Ukuba khona kwezikhala ezingenalutho kusiguquli kuzoholela nakanjani ekulahlekeni kwesignali yesathelayithi.
Kungakhathaliseki ukuthi yiluphi uhlobo lokuxhumana olusetshenzisiwe, ikhwalithi yesignali izokwehla futhi izobonakala kakhulu. Inketho engcono kakhulu kungaba ukumane uthenge imishini emisha uma udinga ukwandisa inethiwekhi yakho yasekhaya. Ake sikhulume ngesihlukanisi sesignali, esibizwa ngokuthi “splitter”. Ngenhla, sixoxe ngeziguquli ezinemiphumela eminingi. Kodwa kuthiwani uma unesiguquli esinokukhishwa okukodwa okuzimele, futhi ungafuni ukusishintsha ufake esisha esinwetshiwe? Kulesi simo, isihlukanisi sesignali sizoba usizo. [i-id yamagama-ncazo = “okunamathiselwe_6664” align = “aligncenter” wide = “363”]
I-splitter yesiginali ikuvumela ukuthi uthumele isignali kuma-TV angu-2 ngosamukeli oyedwa [/ amazwibela] Izihlukanisi, kanye neziguquli, ziza ngenani elihlukile lemiphumela. Kodwa kufanele uqonde ukuthi uma uhlukanisa isignali enamandla (ebuningini bokusakazwa), ukwamukela kumabonakude kuzoba kubi kakhulu. Lokhu kunengqondo impela, njengoba isiginali evela kokuphumayo kwesiguquli iklanyelwe ngokuzenzakalelayo ukuthi yamukelwe kudivayisi eyodwa. Futhi isihlukanisi sihlukanisa isignali eyodwa enjalo ibe amadivaysi amabili, amane, ayisishiyagalombili … Ngaphezu kwalokho, ubude bekhebula kudivayisi ehlosiwe futhi bunomthelela. Ngisho nasezintanjeni ezingcono kakhulu, kunephesenti elithile lokulahlekelwa ngamabanga. Lokhu akuwona kuphela ukonakala kokuhlukanisa isignali ngale ndlela. Isignali yesathelayithi inepharamitha efana ne-polarization. Iziteshi zisakazwa ngezindlela ezimbili: ezivundlile neziqondile. Basebenzisa ama-voltages ahlukene emsebenzini wabo, i-13v ne-18v, ngokulandelana. Uma usebenzisa isihlukanisi ukuhlukanisa isignali, umamukeli ulahlekelwa amandla okushintsha le voltage. Kalula nje, ukubuka ngesikhathi esisodwa iziteshi ezimbili ezihlukene ezine-polarization kuba yinto engenakwenzeka ngokobuchwepheshe. Eminyakeni embalwa edlule, lesi simo besingabucayi kangako, ngoba cishe zonke iziteshi zine-polarization efanayo.

Ama-TV amabili kuya kwabemukeli be-Tricolor ababili [/ amazwibela] Ase achazwe ngaphambilini, lezi izinkinga nge-polarization. Yiqiniso, ezimweni eziningi, abasebenzisi bazokwazi ukubuka iziteshi ezahlukene njengokungathi akwenzekanga lutho. Nokho, uma beqala ukubuka iziteshi ezine-polarizations ehlukene, esinye sazo sizomane sibe nesikrini esimnyama esikhundleni sokusakaza. Ungakwazi futhi ukucabangela le nketho yokuxhuma:
Kusikhumbuza kancane icala esilicabangele lapho sixhuma ama-TV amabili kushuna owodwa. Lapha, ngendlela efanayo, ikhebula elivela ku-converter lingena ku-socket kumamukeli oyinhloko, futhi lokhu okulandelayo, “kunikeza” isignali ephumayo kumamukeli wesigqila. I-TV yesibili isivele ixhumeke kweyakamuva futhi ithola isithombe. Kubonakala kuyizinhlelo ezimbili ezihlukene, kodwa kunezinkinga ezifanayo ncamashi. Isignali yokuphumayo isekunguqulo eyodwa futhi isivele ihlukaniswe yisamukeli esiyinhloko. Ngakho-ke, izinkinga nge-polarization aziyi ndawo.
Manje sifika kunketho yokuxhuma ebiza kakhulu futhi enethezekile. Njengoba kungabonwa emfanekisweni, lesi sijikelezo sesivele sisebenzisa isignali engaphezu kweyodwa ephuma kusiguquli. Isiguquli semiphumela emibili asiyona intokozo eshibhile, ngokusobala izobiza ngaphezu kokuthenga isihlukanisi esilula sesignali. Kodwa lezi zindleko zinezinzuzo zazo. Amasignali amabili alinganayo azimele afika kokokufaka okubili kwebhokisi eliphambili le-set-top. Ngesikhathi esifanayo, ishuna yesibili, ekhonjiswe esithombeni, ayinaso isamukeli sayo. Konke ukwamukela kwenziwa nge-master tuner. Kwenziwani lokhu? Ukunciphisa izindleko zomamukeli wesibili. Wonga “ipeni” eyengeziwe ongayisebenzisa kusiguquli se-2-output efanayo. Amashuna axhunywe kwelinye ngekhebula le-Ethernet elijwayelekile nelijwayelekile. Yiziphi izinzuzo zalolu hlelo? Futhi zisobala. Njengoba kukhona amasignali amabili angenayo avela kusiguquli, bese umamukeli ngamunye wokusakaza uzimele komunye nomunye. Iziteshi ezine-polarization ehlukene azisenayo inkinga, zingabukwa ngokuphephile ngesikhathi esisodwa kuma-TV amabili.
