Zoyenera kuchita ngati TV sichifufuza ndikupeza njira zama digito – sizitenga chizindikiro ndi zovuta zina

Kulumikiza wailesi yakanema ya digito sikovuta, koma zimachitika kuti palibe njira. Ngati TV sichifufuza kapena sichipeza njira zamakono, muyenera kudziwa chomwe chimayambitsa ndikuchichotsa. Mutha kuthetsa vutoli nokha, popanda kuthandizidwa ndi katswiri, koma nthawi zina amatha kukonza vutoli muutumiki.

Chifukwa chiyani ma TV sagwira njira zama digito ndi choti muchite

Kuti mumvetsetse chifukwa chake makanema apawayilesi a digito sakuwonetsa , muyenera kudziwa komwe kulephera kudachitika. Popeza mwazindikira vutoli, ndizotheka kuthetsa nokha popanda kuthandizidwa ndi katswiri.

Mavuto a Hardware

Mavuto ndi zida zolumikizira TV ya digito. Pofuna kuthetsa cholakwikacho, ndikofunikira kuzindikira kusagwira ntchito kwa chipangizo chimodzi kapena china. Pankhaniyi, timalimbikitsa kulankhulana ndi akatswiri, osati kuyesa kuthetsa vutoli nokha.

Digital set-top box osapeza ma tchanelo

Kusagwira bwino kwa chipangizo cholandirira kumatha kuwerengedwa ndi zizindikiro zotsatirazi:

• maonekedwe a mawu akuti “palibe chizindikiro”;
• kuzimitsa modzidzimutsa kapena kuyambitsanso;
• Kuwala kwa LED pa cholandirira ndi mdima.

https://youtu.be/4fRdee5g6xs Pazifukwa izi, pakhoza kukhala firmware yolandila bwino kwambiri. Mutha kukonza vutoli mwa kuwalitsa zida. Pulogalamu yamapulogalamu imapezeka patsamba lovomerezeka la wopanga, ikhala yokwanira kutsitsa ndikusintha chipangizocho.

Ndi bwino kupereka kuwala kwa katswiri.

Mlongoti

Ngati pali vuto, yang’anani kaye mlongoti . Pakutumiza kwa siginecha ya analogi, ma antennas a MW amagwiritsidwa ntchito, chizindikiro cha digito – UHF. Ngati pali nsanja za TV pafupi ndi inu, muyenera kukwera amplifier , popeza popanda izo simungathe kugwira njira imodzi.

Chingwe

Zingwe zolakwika zimatha kusokoneza magwiridwe antchito a TV yanu. Mufunika:

1. Onani maulumikizidwe onse ndi kukhulupirika kwa waya.
2. Ngati chingwecho chili ndi okosijeni, chiyeretseni.
3. Ngati zawonongeka, sinthani.

Ngakhale kupindika pang’ono mu waya kumatha kukhudza kufalikira kwa kanema wawayilesi wa digito.

Mutha kuthetsa vuto la kutayika kwa ma siginecha ndi zovuta zina ndi chizindikiro cha TV pakali pano .

Kodi TV imathandizira TV ya digito?

Kuti muwonetsetse kuti TV imathandizira kuwulutsa kwa digito, phunzirani mosamala zolemba zaukadaulo. TV ndi yoyenera ikukonzekera njira digito ngati ndime “DVB-T2” ndi “inde”. Cholembacho chimapezeka pabokosi la fakitale la TV.

Ngati pali mawu akuti “DVB – T” – muyenera kugula bokosi lokhazikitsira, chifukwa mawonekedwewa ndi achikale ndipo sagwirizana ndi kuwulutsa kwa digito.

Kuthekera kwa ikukonzekera kumatsimikiziridwa ndi kukhalapo kwa chochunira chapadera. Nthawi zambiri kuthandizira kwa ” DVB-T2 ” muyezo kumasonyezedwa ndi chilembo “H”, koma chizindikirocho chimasiyana malinga ndi chitsanzo ndi wopanga. Ma module a DVB – T2 akhoza kukhala:

• omangidwa – gawo la hardware lomwe lili mkati mwa TV;
• kunja – chipangizo chodziimira chomwe chimagwirizanitsa ndi TV.

Pa ma TV okhala ndi chochunira chomangidwira, mutha kuyamba nthawi yomweyo kuwonera TV ya digito mutalumikiza chingwe cha mlongoti. Ngati TV ndi yakale ndipo ilibe zida izi, ndiye kuti muyenera kugula bokosi lapadera lapamwamba.

Zifukwa zina

Pakhoza kukhala zifukwa zina zingapo:

1. Kuwonongeka kwa TV . Uthenga “palibe chizindikiro chochokera pa router” udzawonetsedwa pa TV. Kotero chochunira chikugwira ntchito, koma chiri mu TV.
2. Zokonda zasokonekera . Zokonda zimatayika kwathunthu mwangozi. Pankhaniyi, bwererani chochunira ku zoikamo fakitale. Pambuyo pake, muyenera kufufuzanso ma tchanelo a TV ndikuwasintha.
3. Chizindikiro chosakhazikika . Mlongoti ukhoza kugwa kapena kusintha njira pazifukwa zilizonse. Ibwezereni pamalo ake pomwe zonse zikhala bwino.
4. nyengo . Makanema amatha kusokonezedwa kapena kutha. Zoyipa pawayilesi yakanema ya digito, zitha kukhudzidwa ndi:
   • mvula;
   • mkuntho;
   • kuzizira.

Ngati tchanelo chimodzi kapena zingapo zikusowa

Pali nthawi pamene, pofufuza, TV sipeza njira imodzi kapena zingapo za digito. Zomwe zimayambitsa:

• mavuto luso – ndi bwino kutenga TV ku utumiki;
• madalaivala achikale pa TV – sinthani pulogalamuyo (zosinthazo zitha kupezeka patsamba la wopanga);
• ntchito zoteteza;
• kutha kwa kanema wawayilesi.

Ngati palibe yeniyeni TV njira, ndiye anazimitsa kuwulutsa digito kapena kusintha pafupipafupi ntchito. Zambiri za izi zitha kupezeka patsamba la tchanelo.

Pamene diplexer ikugwirizana

Ngati antennas onse a digito ndi satana alumikizidwa kubokosi lapamwamba kudzera pa diplexer, ndiye kuti muyenera kumvetsetsa kuti amakhalabe zida zosiyanasiyana. Kwa wogwiritsa ntchito, zimagwira ntchito ngati imodzi. Koma chipangizo chilichonse chimagwira ntchito mosiyana.

Diplexer ndi chipangizo cholumikizira pafupipafupi chomwe chimapangidwa kuti chilandire ma siginecha awiri nthawi imodzi, omwe amachulukitsa (amaphatikiza) ndi ma demultiplexes (kuwachotsa).

Mawonekedwe ndi Kusiyana kwake:

• Kulandila kwa Signal. Kwa mlongoti, khalidwe la chizindikiro ndi nyengo ndizofunikira. Ndikofunikira kwa satelayiti kuti palibe kusokoneza mu mawonekedwe a nyumba zapamwamba pakati pake ndi mbale.
• Kuwulutsa. Mukayimitsa kwakanthawi kapena kusintha ma frequency pa imodzi mwa tinyanga, kuwulutsa kumapitilira kwina.

Ngati, pogwiritsira ntchito diplexer, TV ikuwulutsa pa imodzi mwa zizindikiro (DVB kapena DVB-T2), ndiye kuti vuto liri mu imodzi mwa izo. Ngati palibe njira imodzi pazizindikiro zonsezi, izi zikutanthauza kuti ntchito yokonza ikuchitika.

Ngati palibe chinathandiza

Ngati mwayesa zoikamo zonse, ndipo TV akadali sapeza njira, ndiye pali vuto mu chochunira kapena mlongoti. Kuti muwone, mutha kulumikiza mlongoti wina kapena bokosi lokhazikitsira pamwamba kuti muwonetsetse kuti vuto silili pa TV.

Zida zolakwika zimatumizidwa ku diagnostics ku utumiki, kumene chifukwa cha vutoli chimanenedwa.

Mawonekedwe akusintha kodziwikiratu komanso kusaka pamanja

Nthawi zina, makina osintha amatha kubwereza kapena kusabweretsa zotsatira zomwe mukufuna. Pachifukwa ichi, muyenera kugwiritsa ntchito njira yosinthira pamanja.

Kusaka zokha sikupeza njira za digito za Samsung – timathetsa vutoli pamanja

https://youtu.be/CkJUmsEG2SU Kuti mupeze mayendedwe a digito pa Samsung TV yanu, chitani izi:

9. Kusaka tchanelo kukamalizidwa, sungani.

Njira yosakira njira yamanja imatha kutenga mphindi 15 mpaka 20.

Sinthani pamanja kulandila kwa mayendedwe pa LG TVs

Ngati mukukhala kunja kwa mzindawu, ndiye choyamba muyenera kuonetsetsa kuti dera lanu likuphatikizidwa ndi malo oulutsira mawu. Kuti muchite izi, pitani patsamba la RTRS ndikupeza dera lanu komweko (zinambala zikuwonetsa komwe akubwereza). Ngati muli kutali kwambiri ndi iwo, timalimbikitsa kugwiritsa ntchito miyezo ina yowulutsa (satellite, analogue kapena iptv ). Momwe mungasinthire makanema pa LG TV:

1. Tengani chowongolera chakutali cha TV ndikudina batani la “Home”, sinthani ku tabu yotchedwa “ Zikhazikiko “ .
2. Sankhani “Zosankha”, ikani dziko lomwe mukukhala. Ngati tikukamba za chitsanzo chomwe chinatulutsidwa pambuyo pa 2011, sankhani dera la “Russia”, ngati sichoncho, sankhani limodzi mwa mayiko ku Western Europe.
3. Ngati TV idapangidwa isanafike 2011, ikani chilankhulo cha Chirasha pagawo loyenera kuti mupewe zovuta pakukhazikitsa kotsatira.
4. Bwererani ku tabu ya “Zikhazikiko”, sankhani lamulo la “Kusaka pamanja”.
5. Sankhani “Quick Jambulani” pofotokoza pafupipafupi, kuchuluka kwa jambulani ndi kusinthasintha monga zikuwonekera pachithunzichi. Dinani batani la “Update”.
6. Ngati ma tchanelo apezeka, asungeni.

Pafupifupi, kufufuza kumatenga mphindi 15-20 (malingana ndi mtundu wa TV ndi malo omwe alipo).

Sony Bravia – kuyika pamanja manambala ngati TV siipeza zokha ma tchanelo

Kuti muyambe kukonza tchanelo pamanja, muyenera kukhazikitsa tsiku ndi nthawi yeniyeni pa TV iyi. Izi zitha kukhudza zokonda pa TV ya digito. Tiyeni tipite kuzikhazikiko za Sony Bravia TV:
