Ithelevishini yi ... Ziziphi iintlobo zethelevishini?

Kwimizuzu engaphezu kwesigama, umabonwakude ungenye yezindlela eziphambili zokuhambisa ulwazi kubantu abaninzi ngexesha elifanayo, kunye nendlela yokuphumla emva komsebenzi wosuku kwaye ujabule ngeveki.

Inkqubela phambili yezobugcisa ihamba ngokunyuka kunye nemida, iintlobo zokutshintshwa kwendlela yokusasazwa, kunye nokufumaneka komabonwakude kuluntu.

Umabonwakude waqala njani?

Umhla apho i-TV yeSoviet yaqala ukuhlawula kwayo ngo-Apreli 29, 1931, xa umfanekiso wokuqala wethelevishini usasazwa.

Ukususela ngoko, uphuhliso lwetheknoloji aluzange lumile. Ukuba kwixesha lamaSoviet, iiseti ezimbini zeTV zazinokuzithengisa intsapho, kwaye yonke intsapho yayiza kukhangela ukuhanjiswa kwamanqaku kwitheyardhi enye (kunye namaxesha angabamelwane), kodwa ngoku akukho mntu uyamangalisa ngokusasazwa kweTV kwi-tablet okanye kwi-laptop naphi na ukufikelela kwi-intanethi.

Ether TV

Uninzi, Mhlawumbi, umabonwakude ophezulu waseRussia ungokoqobo. Ukuhanjiswa kwayo kuzo zonke iidolophu, iifowuni zethelevishini zifakwe - ziphinda ziphinda zikhulise isignali engenayo.

Ngenxa yobukhulu kunye nokuphambili kwale hlobo lokusasazwa, iziteshi ezinkulu zeTV zifumaneka kubemi baseRussia nakwiinkalo ezincinci, ezikude zelizwe.

Ukuze ufumane isalathisi somhlaba ekhaya, kufuneka ufake i-antenna uze uyidibanise kwiTV. Ungasebenzisa kwakhona i-antenna eqhelekileyo, ukuba uhlala kwisakhiwo sezindlu.

Umabonwakude we-etheri u-analog, kodwa ngokusasazwa kwedijithali kwakusasazeka ngokukhawuleza nangokukhawuleza. Ukuze ukwazi ukufumana ithelevishini yomhlaba wedijithali, kufuneka ube neTV nge-switch-power-switching capacity ukusuka kwi-analog ukuya kwidijithali. Ukuba oku akunjalo, ungasebenzisa i-tuners ekhethekileyo yeTV (iibhokisi eziphezulu zeTVs).

Ngenxa yokuxhaphaka ngokubanzi kwe-TV emoyeni, isikhangiso esibekiwe kuso sinceda ukufikelela kwibala elibanzi lwabathengi.

I-TV yombane

Ukususela kwimbono yokufikelela kubaphulaphuli, umabonwakude uhlala kwindawo echasene nale ndawo. Injongo yaso ephambili ayikho ukusasazwa kwemali kunye nokuzisa iinkqubo zeTV kubaninzi ababukeli kangangoko kunokwenzeka, kodwa ukungafani nokwaneliseka kwezidingo zabantu abaneemfuno ezahlukileyo.

I-TV ye-Cable iboniswe ngeendlela ezahlukeneyo zezifundo ezahlukeneyo. Abo banomdla kwizemidlalo banokubukela ukusasazwa kwemincintiswano eyahlukeneyo. Kwiintsapho kunye nabantwana kukho iindlela ezikhethekileyo zabantwana nezengqondo. Kukho iziteshi zeTV, imini nobusuku ezibonisa iinkqubo zeendaba, ama-movie, amavidiyo omculo okanye iinkqubo zokuzonwabisa.

Ukuxhuma kwi-TV ye-cable, kufuneka uqhagamshelane nomqhubi osondeleyo (kaninzi nabo banika iinkonzo ze-intanethi). Ukuba uhlala kwisakhiwo sezindlu, ngokuqinisekileyo kukho enye okanye iinkampani ezininzi ezikulungele ukukhupha ukubhalisa kwakho kunye nokwandisa ikhefu kwigumbi.

I-TV yeThalamende

I-TV yeThalamende yenye uhlobo lokusasazwa kwabaphulaphuli. Ukusasazwa okunjalo kumabonwakude kuqhutyelwa ngoncedo lweetelletti ezininzi ezindizayo ezindizayo.

Ukufumana uphawu lwe-satellite ekhaya, kufuneka uthenge i-antenna ekhethekileyo ("isitya se-satellite") kwaye uyibeke phezu kophahla kwendlu okanye kwibhantshi. Kubahlali bezinye iindawo ezikude, yile ndlela yodwa ithelevishini ingabafumana ngayo.

Ukufihla ubuninzi bomhlaba womhlaba ngama satellithi kufumaneka kwindawo ethile kwindawo. Zifumaneka kunye ne-equator kwaye zihambela kwijubane elinjalo apho umbonisi uya kuziva ngathi ahlala ephakamileyo kwindawo.

Ngokwahlukileyo kwi-TV, i-satellite ye-satellite ithola inzuzo engenayo ngaphandle kwintengiso, kodwa ivela kwiirhafu zokubhaliselwa kwababhalisi. Ngoku kutshanje, ukufunyanwa kwetheyibhile ye- satelesi ye-satelliti yayingenakukwazi ukuthenga wonke umntu, kodwa imeko iya kutshintsha kancane.

TV kwi-intanethi

Ngethuba lethu lokusasazwa kwe-intanethi, i-TV ye-Intanethi yindlela yokuhlala kwintsimi yolwazi, kude kude nekhaya kunye nayiphi na indawo eneTV.

Ukongezelela kokufikeleleka, inzuzo enkulu ye-interactive (inthanethi) kumabonwakude yinkqubo yokulawula ukubhaliselwa kwiitoni zeTV, apho unako ukhetha ukhethe ngqo abo banomdla okwangoku.

Enye inzuzo yolu hlobo lokusasazwa kukungabikho kokuzibophelela kwixesha lokusasaza. Umbhalisi unokuhlala ebeka inkqubo yenzalo ngexesha lokuyeka okanye ukujonga kamva kwirekhodi.

Ungakhetha njani?

Kukho imigaqo ethile Unokukhetha uhlobo olulungileyo lokusasaza.

- Imali yokubhaliselwa. Ngoku ke kuphela kwi-TV kunye ne-satellite ye-satellite, kodwa nayo ingabonakala emoyeni emva kokutshintshwa ngokubanzi kwithelevishini yomhlaba we-digital. Kwi-TV yekhebula, ikhadi lihlala lihlala kwaye liquka ngokubanzi iitishi eziyi-100 (ngaphezu kweendawo ezisemhlabeni). Ixabiso lentetho ye-TV ye-satel ilawulwa liqela leziteshi zeTV ezixhunyiwe.

- Izixhobo. AmaTV kunye nama-antenna okufumana i-TV yomhlaba kwiidolophu zifakwe kwiindawo eziqhelekileyo kwaye ngokuqhelekileyo azidingi ukuthengwa kwezixhobo ezihlukeneyo. Kwiindawo ezikude okanye kwiidolophana zeeholide, okukhethwa kukho kukuthenga i-TV ye-satellite. I-TV ye-Cable ixhomekeke kakhulu kwi-intanethi kumsebenzisi wekhaya lakho.

- Ukufumana umqondiso. Kwizakhiwo ezininzi zezakhiwo, umfanekiso ochanekileyo ufezekiswa ngoncedo lweetambo, kanti kungcono ukuxhuma kwisitya se-satellite ngaphandle kwesixeko. I-TV ye-Analog ifanelekile kulabo baqhele ukusetyenziswa kweTV njengemvelaphi kwaye abayiqwalasela umgangatho wephawu.
