Iziteshi ezisebhokisini le-digital set-top zanyamalala, ithelevishini yedijithali iqhwa – yini okufanele uyenze uma ingekho isignali?

I-TV kwimodi evamile ibonisa iziteshi zedijithali ezingu-20, kodwa kwenzeka ukuthi ngisho nale nombolo encane iyanyamalala ngokuzumayo. Njengoba iziteshi zimahhala,
ukwehluleka kokusakaza kungaba ngenxa yezinto ezihlukahlukene, kodwa ngokuvamile lezi yizinkinga ohlelweni noma kudivayisi ethola isignali. Ezinye izinkinga ungabhekana nazo uwedwa.

I-TV yedijithali ayibonisi ngenxa yokwephulwa kwezobuchwepheshe noma umsebenzi wobuchwepheshe

Ezimweni eziningi, izici zokunyamalala kweziteshi ezimbalwa ebhokisini le-digital set-top ziwukuphazamiseka kwezobuchwepheshe okuhlotshaniswa nokwamukela isignali. Kuyenzeka futhi ukuthi ukusakazwa kwethelevishini yedijithali kuphazamiseke ngenxa yomsebenzi wezobuchwepheshe, okuyiphuzu eliphoqelekile lokugcina ukusebenza kwesistimu. Ngaphambi kokuthi uthole inkinga noma ushayele iwizadi, kufanele uzame ukuzifunela iziteshi ezingekho:

1. Yiya esigabeni sezilungiselelo ku-TV.
2. Khetha “Izilungiselelo ezizenzakalelayo” kuqala, bese “Sesha ngokuzenzakalela”. Uhlelo luzozama ukuthola iziteshi.
3. Uma ungekho umphumela, kufanele uzame ukusesha mathupha. Ukuze wenze lokhu, khetha isigatshana esithi “Ukucushwa kwe-Manual”, setha imingcele edingekayo kuyo, emva kwalokho inqubo iqala.

Indlela yokusetha ibhokisi le-digital set-top kumodi yezandla ichazwe kuvidiyo elandelayo (into kuphela okudingeka uyenze ukuthola ipuleti elinamaza nezinombolo zeziteshi zikamabonakude wedijithali wedolobha lakho noma isifunda ku-inthanethi) : https://youtu.be/hcioy_kAZYQ

Ngemva kokuzama kokuqala, ezinye iziteshi kodwa hhayi zonke zingatholakala. Khona-ke inqubo kufanele iphindwe kuze kube yilapho kuvela isiteshi ngasinye esinyamalele.

Uma imizamo ingenamsebenzi, kuzodingeka ubheke inkinga ebaluleke kakhulu. Isiteshi esinyamalele ebhokisini le-digital set-top singavele sivalwe. Khona-ke kungokwemvelo ukuthi ayikho kunethiwekhi. Isiteshi singabhalwa ngekhodi, kodwa lesi simo singalungiswa uma uthanda: udinga ukuthenga ikhadi le-SMART kumhlinzeki. Ezinye izimbangela zokuphazamiseka kokwamukela isignali yedijithali nokuqedwa kwazo kunikezwe ngezansi.

Iziteshi ezilahlekile ebhokisini le-digital set-top ngenxa yombhalo wekhodi ongalungile wesiteshi se-DRE

Kwesinye isikhathi into edala ukunyamalala kweziteshi ezimbalwa ebhokisini le-digital set-top wumbhalo wekhodi oyiphutha wesiteshi se-DRE. Kubonakala uma ibhokisi le-set-top lisesimweni sokunqanyulwa kunethiwekhi isikhathi eside. Awudingi ukulungisa noma yini: udinga nje ukuvula idivayisi futhi uyishiye isebenza amahora ambalwa. Lesi sikhathi sanele ukuvumelanisa umsebenzi. Ibhokisi lokusetha elibuyisiwe lizoqala ukubonisa amashaneli futhi.

Ayikho isignali ye-TV yedijithali ngenxa yokuntuleka kokubhaliswa kweshuna yedijithali

Esinye sezizathu zokunyamalala kweziteshi eziningana ngesikhathi esisodwa ukuntuleka kokubhaliswa kwe-tuner. Ukuba khona kokubhaliswa kuwebhusayithi esemthethweni yomhlinzeki kuyahlolwa. Uma ingekho, khona-ke udinga ukubhalisa isiqalo: faka inombolo kamazisi – izinombolo ezingemuva kwecala ledivayisi.

Ukunqanyulwa kokubhalisa ezinsizeni ezihlinzekwa umhlinzeki

Uma umsebenzisi engakakhokheli ukusetshenziswa komabonakude wedijithali ngesikhathi esifanele, khona-ke ukusakaza kuyaphazamiseka, futhi kuvela inkomba esikrinini yokuthi iziteshi ziyakhokhelwa. Isixazululo senkinga sisobala: udinga ukukhokhela isevisi, futhi iziteshi ezikhokhelwayo zizovela futhi. Nokho, isexwayiso sesimo esikhokhelwayo singase sivele nasesiteshini samahhala, okungafanele kube njalo. Kulokhu, udinga ukudinga incazelo kumhlinzeki. Mhlawumbe iziteshi zisuke kwezamahhala zaya kwesikhokhelwayo.

Umthelela wesimo sezulu esibi othini

Umabonakude wedijithali uvamise ukunyamalala noma ukhombise kabi ngenxa yezimo ezingezinhle zomkhathi. Phakathi nokuduma kwezulu, isignali idluliselwa ngezikhathi ezithile. Umoya oshisayo uphazamisa ukusebenza
kwe- antenna , ngenxa yalokho amashaneli asebhokisini le-digital set-top alahleka ngokuphelele noma kancane.

Awudingi ukwenza lutho: lapho isimo sezulu sibuyela kwesijwayelekile, amashaneli azoqala ukusebenza futhi. Donsa uthi, ungalunyakazi. Ngemuva kokuphela kokuduma kwezulu, kufanelekile ukuhlola ukuthi ikhebula elixhuma i-antenna ne-set-top box liphelele.

Ayikho isignali yethelevishini yedijithali: kungani futhi kufanele wenzeni

Izizathu zeqiniso lokuthi umlayezo othi “Ayikho isignali” ephuma esikrinini sethelevishini ingaba yizici ezihlukahlukene. Ukuze uqonde inkinga, umsebenzisi kufanele aqhubeke ngezigaba:

1. Hlola isimo nokuzinza kokuxhumeka kocingo ngalunye . Kwenzeka ukuthi izintambo ze-antenna ziklebhukile, zigobile, zine-oxidized. Kwanele ukuhlanza ikhebula eline-oxidized, futhi izintambo ezilimele kufanele zishintshwe. Ngisho nokugoba kancane kwekhebula kungabangela ukungasebenzi kahle kwedivayisi.
2. Qiniseka ukuthi imenyu yokusebenza ye-set-top box iboniswa esikrinini . Uma kungenjalo, kuzomele uhlole izixhumi ze-RCA. Ngokuvamile amapuleti angaphandle awonakaliswa kuwo, ngenxa yokuthi isignali iphazamiseka.
3. Bheka imephu ye-TV yedijithali . Abanye abasebenzisi bathenga i-set-top box ngaphandle kokwazi ukuthi ukuxhumana kwedijithali akukakasungulwa endaweni abahlala kuyo.

Kungani ingekho isignali kumamukeli wedijithali futhi zingekho iziteshi eziboniswayo: https://youtu.be/eKakAAfQ2EQ Kungani ibhokisi le-digital set-top libonisa iziteshi ezingu-10 esikhundleni sika-20 nokuthi yini okufanele yenziwe: https://youtu.be /3kk8rVSYMA4

Isofthiwe engahambelani

Kusamukeli sesathelayithi se-GS-HD, udinga ukufaka imenyu, khetha inketho ethi “Buyisela uhlu lwesiteshi”. Uma ukungahambisani kwesofthiwe kuqinisekiswa, khona-ke kusilawuli kude udinga ukuthola izinkinobho ze-CHANNEL ne-TV/REDIO. Lezi zinkinobho kufanele zicindezelwe kanyekanye ku-set-top box naku-remote control, ngemva kwalokho umyalo othi STANDBY kumelwe kukhethwe kusilawuli kude.

Ukuhluleka kwezilungiselelo ze-antenna

Ingxenye yamashaneli ingase ilahleke uma izilungiselelo zothi zihluleka. Uchwepheshe kuphela ongabhekana nale nkinga, ngakho-ke kufanele ushayele ihhovisi lomhlinzeki futhi ucele ukulungiswa kabusha. Ukuxhumana phakathi kwekhebula nothi noma ibhokisi le-set-top nakho kuba buthakathaka. Kuyadingeka ukuhlola ukuthi ucingo luxhumeke kahle yini kusixhumi se-LNB IN.

Amandla e-antenna anganele

Ukudluliselwa kwesignali yedijithali endaweni ethile kwenziwa ngemvamisa efanayo, okungukuthi, iziteshi zisakazwa ngokuhlanganyela. Uma iziteshi ezimbalwa zingekho, khona-ke imbangela ingase ibe amandla e-antenna angafanele. Ukuze uhlole ukuqagela kwakho, udinga ukuthatha isilawuli kude bese uchofoza kabili kusithonjana “i”. Inqubo yokuxilonga i-antenna izoqala. Amabha amabili azovela kusikrini se-TV, abonise izinga lamandla edivayisi. Uma inkomba ibuthakathaka, khona-ke udinga ukuhambisa i-antenna ukuze uthole okungenani amandla angu-50%. Ngakho isignali izothuthuka, iziteshi ezinyamalale zizoqala ukusebenza. Indlela yokuhlola isignali ye-antenna, bheka ividiyo elandelayo: https://youtu.be/R-IKTeVhGvc

Uma singekho isithonjana esithi “i” kusilawuli kude, kuzomele ubheke emiyalweni yegama lenkinobho yokuxilonga amandla. Kufanele kube, kodwa ngaphansi kwegama elehlukile.

Lapho ukhetha i-antenna esitolo, udinga ukucabangela ukuthi kude kangakanani nendawo yokuhlala umbhoshongo wethelevishini utholakala:

• uma ibanga lifika ku-2 km, khona-ke kwanele ukuthenga i-antenna yasekhaya elula;
• uma ibanga lifinyelela ku-30 ​​km, khona-ke idivayisi ithengwa iphelele nge -amplifier yesignali ;
• ibanga elifika ku-70 km – lidinga i-antenna yangaphandle, ehambisana ne-amplifier.

Amandla we-amplifier nawo kufanele acatshangelwe. Akufanele uthathe idivayisi enamandla kakhulu – ingase ingathuthuki, kodwa yenza buthaka isignali.

Indlela
yokwenza i-antenna ye-TV yedijithali ichazwe kwesinye isihloko sethu. Mhlawumbe kuyoba usizo kuwe.

I-TV ayiwatholi amashaneli edijithali ngenxa yokulimala kwe-set-top box

Isiqalo kufanele siyiswe esitolo sokulungisa uma:

• ulwazi mayelana nalo aluboniswa ku-TV, kodwa izixhumi ze-RCA ziyasebenza nakanjani;
• idivayisi emisiwe iziqalisa kabusha;
• lapho ucinga isiteshi, ulwazi mayelana nekhwalithi yesiginali eyamukelwe aluboniswa, kodwa uthi lushuniwe.

Ukulimala kwe-TV

Uma i-TV ingavuli nhlobo, khona-ke inkinga ingase ibe nkulu, edinga ukulungiswa okumba eqolo. Kodwa akufanele ugijimele esikhungweni senkonzo – okokuqala kufanele uzame ukulungisa isimo ngokwakho. Mhlawumbe isizathu sokungasebenzi kwe-TV asisibi. Udinga ukwenza ngezigaba:

1. Hlola ukuthi ikhebula lixhumekile yini endaweni yokuphuma nokuthi ingabe ukhona yini ugesi ekamelweni . Izingane ezidlala ekhaya noma izilwane ezifuywayo zinganqamula intambo ngokungaqondile.
2. Qiniseka ukuthi amabhethri kusilawuli kude ashajiwe . Zishintshe uma kunesidingo.
3. Hlola ukuthi ingabe ingaphezulu lebhokisi le-set-top lapho isilawuli-kude sikhonjwe khona alivinjwanga yini .
4. Hlola ukusebenza kwesilawuli kude . Ku-TV icishiwe, kufanele kukhanyiswe isibani esincane, okubonisa ukuthi okokusebenza kuyasebenza. Uma isibani singacimi, kodwa i-TV ingavulwa, isilawuli kude sinephutha.
5. Qiniseka ukuthi okokusebenza kusebenza kahle . Uma umsebenzisi ecindezele izinkinobho ezingalungile ngephutha, evula imodi engalungile, efakwe nge-software interface, khona-ke isikrini se-TV esebenzayo sizoba mnyama. Udinga ukubuyela kumodi efanele. Uma ungakwazi ukulungisa iphutha ngokwakho, kuzodingeka uxhumane nomphathi.
6. Thatha i-TV uyiyise endaweni yokusebenzela uma yonakele ngesikhathi kuduma izulu . Kulesi simo, akunakwenzeka ukuthi kuzokwazi ukwenza ukulungiswa ngokwakho.

Ezikhathini eziningi, iziteshi ezisebhokisini eliphezulu ziyanyamalala ngenxa yezenzo eziyiphutha zabasebenzisi ngokwabo, ukungazi ngendawo yokumboza ithelevishini yedijithali. Akufanele ulungise inkinga engathi sína ngokwakho, ukuze ungenzi kube kubi nakakhulu, kungcono ukuxhumana nenkosi efanelekayo.
