Ungaxhuma kanjani ikhebula le-TV mahhala futhi ubuke amashaneli

I-Cable TV ingaxhunywa ngokukhokhelwa futhi mahhala. Yiqiniso, izakhamuzi eziningi zilwela ukukhetha indlela eyongayo. Okulandelayo, sizocabangela izindlela okungenzeka ngazo ukufaka ithelevishini yedijithali yamahhala futhi ubuke iziteshi ngaphandle kokuphula umthetho.

Izindlela zokuxhuma ikhebula le-TV mahhala – ungawakhokheli kanjani amashaneli ekhebula ngokusemthethweni

Uma indlu noma omakhelwane benekhebula le-TV, udinga nje ukusabalalisa ikhebula bese ulixhuma kuwo wonke ama-TV. Noma yisiphi isitsha sesathelayithi kufanele sibe namashaneli amaningana. Zenzelwe ukuxhuma izintambo. Uma kukhona iziteshi zamahhala, ungenza okuthile.
Okokuqala, udinga ukuthenga ikhebula, isihlukanisi, isiguquli kanye nezinye izingxenye ezizofika kahle lapho uxhuma. Ukuthenga kungenziwa esitolo se-hardware noma emakethe, lapho ungathola khona izeluleko. Uma konke sekukhona, kufanele uqale ukufaka izintambo izintambo.
Kuzoba ngu-3 kubo:

1. Okubomvu kuzodinga ukudonswa ku-antenna uqobo, kuye kusihlangu. Futhi ukusuka lapho ukuya ku-TV. Ngale khebula, ungakwazi ukucosha isignali yesathelayithi.
2. Okuluhlaza kusethwe ngendlela efanayo neyangaphambili. Kuyadingeka ukuze kudluliselwe isignali ye-antenna yasemhlabeni.
3. Ikhebula eliphuzi linamathiselwe esihlangu futhi liya ku-TV (noma eziningana).

Zingaki izintambo ezidingekayo ukuze kuxhunywe okuvamile. Noma kunjalo, inombolo yabo incike ekutheni mangaki amaphuzu azimele akhona.

Ungawabuka kanjani amashaneli abethelwe

Ukuze ubuke iziteshi ezibethelwe, ungahamba ngendlela esemthethweni (uyedwa) kanye nendlela engekho emthethweni (izinketho ezimbalwa). Okuwukuphela kwendlela ethembekile ukukhokhela umhlinzeki ngezinkonzo. Lokhu kungenziwa nge-akhawunti yomuntu siqu kuseva yenkampani yesevisi. Kukhona ezinye, izindlela ezinobuqili zokubuka iziteshi ezibethelwe.

Kodwa ukusetshenziswa kwabo kubhekwa njengecala. Kulokhu, udinga ukulungiselela izinhlawulo ngendlela yezinhlawulo.

Uzodinga isidlali semultimedia esiklanyelwe ngqo ukubuka amashaneli abethelwe. Idivayisi kufanele ibe ne-emulator. Uma ingekho, udinga ukuthenga imodeli yesimanje noma ukhanyise kabusha ekhona. Kukhona abamukeli abanikeza ukufinyelela eziteshini ze-TV zekhebula, ngenxa yokwabelana nekhadi. Lokhu kusiza ukuxhuma idivayisi ku-inthanethi.

Ungawaqoka kanjani amashaneli ekhebula

Uma inketho yangaphambilini ingafaneleki, futhi umsebenzisi udinga ukufinyelela eziteshini ezifihliwe ezidumile, kuzodingeka afunde amaqhinga athile. Umsebenzisi ongenalwazi mancane amathuba okuthi akwazi ukuqhekeza ikhodi yesiteshi sekhebula ngokwakhe. Kuyafaneleka ukuqasha uchwepheshe noma ukuzama ukuthola okhiye enetheni. Yebo, ayikho neyodwa isayithi evuliwe ezoshicilela amakhodi eziteshi ezikhokhelwayo ukuze zibonwe yiwo wonke umuntu. Kodwa ikhona indlela yokuphuma. Kunconywa ukubhalisa kumaforamu anezihloko futhi ubhale isikhalazo esifanele kubasebenzisi. Mhlawumbe kukhona ozoba nekhono kule ndawo futhi angasiza. Kunezingxoxo ezixoxa ngokukhipha amakhodi ngesinyathelo ngesinyathelo. Ungacela iseluleko kubangani abane-cable TV. Kungenzeka ukuthi abanye babo bebesebenza eziteshini zokukhipha amakhodi. Futhi, abangani bangeluleka uchwepheshe omuhle wokukhipha amakhodi. Ngayo, uzokwazi ukufinyelela imithombo eminingana yethelevishini ngesikhathi esisodwa. Futhi ukuchezuka kwezinga lesignali ngeke kubonakale. Ungakwazi futhi ukungena esivumelwaneni somuntu ngamunye nenkampani yesevisi yomnikezeli we-cable TV. Iphakheji ekhona yamashaneli inganwetshwa kakhulu, kuyilapho imali yenyanga izokhuphuka kancane.

Awukwazi ukukhokhela i-cable TV ngaphandle kokwephula umthetho

Kukhona indlela elula yokuxhuma i-cable TV mahhala. Ngaphezu kwalokho, akudingekile ukuhlupheka ngezintambo futhi uphazamise omakhelwane. Okuwukuphela kokubi kwalesi sixazululo ukuthi asisebenzi ngaso sonke isikhathi. Uma unekhebula le-TV elixhuma ngentambo ye-coaxial (kunokusebenzisa i-inthanethi), unganciphisa izindleko zibe ziro.
Udinga ukuvakashela ihhovisi lika-opharetha (noma uye kuwebhusayithi esemthethweni) futhi ukhubaze isevisi. Abaningi bayawungabaza lo mbono, ngoba uzosebenza 50/50. Ngemva kokwenqaba, umhlinzeki uthumela inkosi ukuthi ivale i-TV yekhebula. Umqondo uwukuthi izinkampani ezithile zithumela isisebenzi ngemva kwezinyanga ezimbalwa, noma zingasithumeli nhlobo. Uma isikhathi sokusebenzisa ikhebula likamabonakude isikhathi eside, makhulu amathuba okuthi lolu hlelo luzosebenza.

Okubalulekile! Uma ithelevishini isebenzisana, iqhinga ngeke lisebenze. Ngemuva kwakho konke, inkampani izokwazi ukukhubaza insizakalo ngaphandle kokuvakasha kwenkosi – ukude ngenethiwekhi.

Inqubo yokuxhuma ikhebula yedijithali enemininingwane ye-TV

Ukuxhuma i-TV yekhebula yedijithali ngokwakho futhi okungenani izindleko, udinga ukulandela izinyathelo ezimbalwa. I-algorithm yezenzo ihlanganisa izinyathelo ezilula. Ungakukhokheli kanjani i-TV yekhebula futhi ubukele iziteshi ze-TV zamakhebula mahhala ngokusemthethweni uma i-TV yakho ine-Smart TV: https://youtu.be/U9Ohb4qs9P4

Ukusekelwa kwe-TV

Udinga ukuthola ukuthi ingabe i-TV ethile inokusekelwa kwezobuchwepheshe kwefomethi ye-DVB-T(2). Lolu lwazi luseshidini ledatha. Uma kungekho ukusekelwa, ngakho-ke kubalulekile ukunaka igama eliphelele lemodeli yedivayisi. Kufanele ifakwe kubha yokusesha.
Uma imodeli ingatholakali, ngakho-ke kunconywa ukuthi uye kuseva esemthethweni yomkhiqizi futhi uthole igama nolwazi lapho.
Incazelo kufanele iqukathe into “Amasistimu okusakaza”. Lapho udinga ukubheka ifomethi. Uma unokusekela, kufanele uthenge uthi kanye nesitsha sesathelayithi. Ukuze uthole i-TV yedijithali yamahhala, kufanele uthenge uthi lwe-analogi.

Uxhumano lwe-antenna neshuna

Uma umbhoshongo ungekho kude, ngakho-ke akudingekile ukuhlomisa i-antenna. Ngakho-ke, uma itholakala kude, kunconywa ukufaka i-antenna nge-amplifier. Uma ufaka idivayisi ngokwakho, kufanelekile ukuyiqondisa ngqo embhoshongweni. Uma unemodeli ye-TV endala, kuzodingeka uthenge ibhokisi elibekwe phezulu, ngoba ngeke libe nesamukeli esikhethekile esakhelwe ngaphakathi.

Amabhokisi okusetha phezulu edijithali ayahluka ngezindleko nokusebenza. Amamodeli amaningi abonakala ngezingxenye ezifana nembobo ye-USB ye-flash drive, ikhono lokurekhoda ukusakazwa bukhoma, ukuxhuma kunethiwekhi ye-Wi-Fi nokusebenza ohlelweni lokusebenza lwe-Android.

Ukusetha okuzenzakalelayo

Ukuze uxhume ukushuna okuzenzakalelayo, kufanele ucindezele inkinobho ethi “Imenyu” kuphaneli yokulawula. Ithebhu ethi “Ukucushwa Kobuchwepheshe” izovela esikrinini se-TV, ngemva kokuchofoza, isigaba “sezilungiselelo zesiteshi se-TV” sizovela. Ngemuva kwalokho, vele uqinisekise ukushuna okuzenzakalelayo bese ulinda imizuzu embalwa. Ekugcineni, chofoza inkinobho ethi “Phuma”.

Ukulungiselelwa mathupha

Ukuze uzilungise ngokwakho, kufanelekile ukuya ku-“Menu” bese ukhetha indlela “yokushuna mathupha”. Kuleli qophelo, inkambu yokufaka izovela, lapho udinga ukucacisa imvamisa kanye nenye idatha edingekayo. Ngemuva kwalokho, kufanelekile ukucindezela inkinobho yesilawuli kude “Kulungile”. Ukuze ukusesha kuqhubeke, kufanele uchofoze “Okulandelayo” isikhathi ngasinye. Indlela isetshenziswa isikhathi eside, kodwa isignali izoba ngcono kakhulu. Ungayibuka kanjani i-TV ngaphandle kwe-antenna efulethini, ezweni nangaphandle kwama-opharetha we-TV esemthethweni: https://youtu.be/mcZmzht4_R8

Ixhuma nge-console

Ukuze uxhume ibhokisi le-set-top, uzodinga izimbobo eziningana, phakathi kwazo okufanele kube yi-HDMI. Ngakho-ke kuzokwazi ukufeza isixazululo esingcono nekhwalithi, efanele i-multimedia.
Amamodeli amadala angasebenzisa imbobo ye-AV. Lapho ungafaka amapulaki aphuzi, abomvu namhlophe. Kumamodeli amadala kakhulu, imbobo ye-Scart inikezwa. Uma uxhuma ikhebula kusuka ku-antenna, kuyadingeka ukuxhuma izintambo ngokwemibala. Bese kufanele ufake isiqalo. Kamuva, vula i-TV bese ucindezela inkinobho kusilawuli kude ebonisa indawo ekhethiwe. Bese kufanele ubheke iziteshi ngesilawuli kude esisuka ku-set-top box.

Izinkinga nezisombululo ezingenzeka

Ngosuku lokuqala, amaphutha athile angase avele. Isibonelo, akuzona zonke iziteshi ezizoboniswa, isithombe singanyamalala noma sisebenze ngokubambezeleka, ama-artifact azovela. Kodwa lezi zinkinga ezincane kulula ukuzilungisa. Ukuthola amanye amashaneli, kufanele usebenzise ukulungiselelwa (okuzenzakalelayo noma okwenziwa ngesandla). Uma isithombe singekho, kuphakanyiswa ukuthi uhlole ukuthi izintambo zixhumeke kahle yini. Futhi, umamukeli angase angasekeli ifomethi yamanje. Uma kukhona ukubambezeleka, isikhathi esiqondile kufanele sishiwo. Ngezinye izikhathi, inkinga ilele kukhebula ngokwayo, kungase kube buthaka. Khona-ke kunconywa ukuthi esikhundleni salo kube namandla kakhulu.
