Mavuto ndi wailesi yakanema ya digito: chifukwa chake mayendedwe sagwira ntchito, palibe chizindikiro, pali zosokoneza

Ngakhale kukhazikika kwa chizindikirocho, chifaniziro chapamwamba komanso phokoso panthawi yowulutsa pawailesi yakanema ya digito, zovuta nthawi zina zimabuka powulutsa kanema wawayilesi wa digito. Pachifukwa ichi, ma TV a digito sangakhalepo ndipo samawoneka. Ndikofunika kumvetsetsa zomwe zimayambitsa vutoli ndikuzichotsa.

Zoyenera kuchita ngati palibe chizindikiro cha kanema wawayilesi komanso zomwe zimayambitsa vutoli

Musanayambe kukonza vutoli, muyenera kudziwa tanthauzo lake. Chizindikiro cha digito cha TV chikhoza kuzimiririka pazifukwa zina:

• multiplex anasiya kuulutsa chizindikiro TV;
• kugwira ntchito yokonza;
• zotsatira za nyengo;
• zida zolakwika.

Choyamba muyenera kuonetsetsa kuti TV ili mu zone yodalirika kulandira chizindikiro. Ngati chipangizocho chikuwonetsa chithunzi ndikuyimitsa, ndiye kuti mlongotiyo sunalumikizidwe bwino . Ngati zida zomwe zayikidwa ndizo zomwe zimayambitsa vutoli, ndiye kuti muyenera kudziwa kuchuluka kwa njira zama TV za digito: mapulogalamu kapena zida. Kuphatikiza apo, zokonda pa TV zitha kulakwika, pambuyo pake zidasiya kuwonetsa.

Kuyimitsa kuwulutsa kwa TV

Ngati chizindikiro cha kanema wawayilesi sichinagwire, muyenera kuwonetsetsa kuti palibe kukonza zodzitetezera. Mutha kudziwa za izi patsamba lawayilesi, pomwe ndondomeko yachitetezo ndi kukonza iyenera kusindikizidwa. Pa ntchito yoyesera, multiplex yachiwiri imazimitsidwa ndipo zofunikira zimasonkhanitsidwa, ndiye kufalitsa kumayimitsidwa. Tsopano m’madera ambiri a ku Russia ndi phukusi limodzi lokha lomwe limagwiritsidwa ntchito poulutsa pawailesi yakanema.

Ntchito yokonza

Mutha kudziwa za ntchito yokonza patsamba la rtrs.ru. Nthawi zambiri zochitika zoterezi zimachitika chifukwa cha kuwonongeka kwa zida pa nsanja ya TV chifukwa cha nyengo yoipa.

Simawonetsa TV chifukwa cha nyengo

Chizindikiro chofooka cha digito cha TV chingakhalenso chifukwa cha nyengo yoipa. Mphepo yamphamvu, mvula, mvula yamkuntho zimakhudza mtundu wa kulandira chizindikiro. Pankhaniyi, khalidwe la chithunzi ndi phokoso likuwonongeka, chithunzicho chikuwonetsedwa m’mabwalo, kapena sipangakhale chizindikiro konse.

Pankhaniyi, muyenera kuyang’ana pa zizindikiro mlingo chizindikiro. Ngati mtengo wake ndi wotsika, uyenera kukwezedwa mpaka pamlingo waukulu.

Zotsatira za nyengo sizingakhale chifukwa cha kutaya kwathunthu kwa ma TV a digito. Izi zitha kufooketsa chizindikirocho.

Zida zolakwika

Ngati phokoso limakhala lachidule, ndipo chithunzicho sichili bwino, ndiye kuti vutoli limapangidwa ndi zipangizo zolakwika. Kuwonongeka kungayambitsenso kusakhalapo kwathunthu kwa chithunzi cha digito. Zolakwika zitha kukhala zogwirizana ndi:

1. Ndi mlongoti . Muyenera kuwonetsetsa kuti mlongoti walunjika ku nsanja ya TV. Nyanga za m’nyumba zimalephera mobwerezabwereza kuposa zakunja. Monga lamulo, zovuta zimachitika chifukwa cha mvula yamkuntho, mphepo yamkuntho kapena mphepo yamkuntho. Kukonzanso wolandila sikungapereke zotsatira. Kuti muwone cholakwika ndikuchikonza, muyenera kuchita izi:
   • fufuzani voteji mu gwero la mphamvu;
   • fufuzani chingwe ndi mapulagi;
   • ngati kuyang’ana zipangizo sikuthetsa vutoli, gwirizanitsani mlongoti watsopano.
2. Ndi attachment . Ndikosavuta kukonza bokosi lokhazikika. Ikayatsidwa, diode yapadera imawunikira ndi kuwala kocheperako kapena siyiyatsa konse. Ngati palibe chomwe chikuchitika ndikukanikiza mabatani kuchokera pa chowongolera chakutali, ndiye kuti bokosi lokhazikitsira pamwamba ndilolakwika. Iyenera kusinthidwa kukhala ina ndikuyang’ana kuperekedwa kwa chizindikiro cha digito. Mavuto omwe angakhalepo ndi prefix:
   • Kuwulutsa pa TV mwina sikungapezeke chifukwa cha mtundu wachikale wa wolandila , womwe uyenera kusinthidwa ndi watsopano.
   • Firmware yabwino kwambiri ya bokosi lokhazikika ikhoza kukhala chifukwa chosowa chizindikiro. Ngati bokosi lokhazikitsira ndi lachikale, muyenera kutsitsa firmware yatsopano kuchokera patsamba lovomerezeka la wopanga, ndikuyisintha. Kuti muzitha kuwunikira bwino, ndi bwino kutembenukira kwa akatswiri.
   • Zolemba za kusakhalapo kwa chizindikiro zitha kuchitikanso chifukwa chokhazikitsanso modzidzimutsa . Kuti muthane ndi vutoli, muyenera kuwonetsetsa kuti chizindikiro cha TV chikulandiridwa bwino ndikufufuzanso njira zatsopano zapa TV.

   Bokosi la set-top likufunika kukonzedwa ngati:

   • palibe chiwonetsero pazenera ngati pali zolumikizira za tulip;
   • pali kuyambiransoko modzidzimutsa kwa nthawi ina pambuyo poti zosinthazo zapangidwa;
   • pofufuza ma tchanelo a TV, palibe chidziwitso chokhudza mtundu wa chizindikiro cha TV pamene mlongoti wakonzedwa.
3. Ndi chingwe ndi maulumikizidwe onse . Mavutowa amapezekanso pafupipafupi. Pang’ono, chingwecho chili mumsewu, chifukwa chake, ndikugwiritsa ntchito nthawi yayitali, mafunde amawonongeka ndikupukuta, ming’alu imawonekera. Ndikofunikira kudziwa ngati pakhala kuphwanya kukhulupirika kwa kulumikizana kwa chingwe chilichonse. Ngati kuwonongeka kwapezeka, chingwecho chiyenera kusinthidwa.

Chifukwa chiyani TV ya digito sakuwonetsa (kapena kuwonetsa molakwika) komanso zoyenera kuchita ngati matchanelo sakugwira ntchito (palibe chizindikiro): https://youtu.be/ZL5Qs_K4xvU

Mavuto omwe angakhalepo chifukwa chomwe TV sichigwira ma digito / sichigwira pang’ono

Mavuto owonetsa makanema apawayilesi a digito amatha kukhala amitundu ingapo. Tiyeni tikambirane mwatsatanetsatane.

Sitinapezeke mndandanda wamakanema onse

Kusaka kodziwikiratu kwachitika, si njira zonse zapa TV zomwe zingapezeke. Zikutheka kuti wolandirayo sanalandire paketi yachiwiri, ndipo tsopano padzakhala kofunikira kufufuza maulendo a nsanja yapafupi yowulutsa TV. Pankhaniyi, mutha kupeza njira zonse pogwiritsa ntchito kusaka pamanja. Nthawi zambiri chifukwa chomwe si njira zonse zomwe zimapezeka zitha kukhala mlongoti womwewo. Iyenera kusankhidwa molingana ndi mtunda wa nsanja m’dera linalake:

• ngati nsanja ili pamtunda wa 1-2 km, ndiye kuti mlongoti wamba wamba ungagwiritsidwe ntchito;
• ngati nsanja ili pamtunda wa 20-30 km, ndiye kuti mlongoti wokhala ndi amplifier wa chizindikiro uyenera kugwiritsidwa ntchito;
• pa mtunda wa 30-70 Km, muyenera kugula mlongoti wakunja ndi amplifier.

Momwe mungapangire mlongoti wa DVB-T2 pawailesi yakanema ya digito nokha ikufotokozedwa m’nkhani yotsatirayi .

Kugwiritsa ntchito amplifier yamphamvu mopanda chifukwa kungayambitse kuwonongeka kwa ma sign.

Chifukwa chiyani sizikuwonetsa TV ya digito kwathunthu

Izi zitha kukhala chifukwa chosankha mavidiyo olakwika kapena kusasintha TV kukhala AV kapena HDMI. Muyeneranso kuyang’ana ngati prefix ndiyololedwa . Izi zitha kudziwika ndi chowunikira chowunikira, chomwe chimayatsa zobiriwira zikayatsidwa. Kuti muyatse bokosi la set-top, gwiritsani ntchito remote control kapena batani lomwe lili pamenepo.

Wolandira wayatsidwa, koma palibe chizindikiro cha digito cha TV

Pachifukwa ichi, ndiye kuti ndi mlongoti wotsekedwa kapena amplifier kwa izo. Muyenera kuyang’ana ngati chikugwirizana, kuchikoka ndikuchiyikanso, ndikubwereza kusaka kodziwikiratu.

Zalembedwa kuti palibe mautumiki, ndipo autosearch sapeza kalikonse

Mukalandira chizindikiro chofooka, kusaka kodziwikiratu kumadumpha njira zapa TV, ndipo kusaka kwapamanja pamafupipafupi aliwonse kumawonetsa mphamvu ya siginecha yofooka kwambiri.

Pali “friezes”: chithunzicho chimagawanika kukhala ma cubes

Muyenera kuyang’ana mphamvu ya chizindikiro. Kuti muchite izi, dinani Info batani pa remote control. Kusokonezeka kwa chithunzichi kumawoneka chifukwa cha kutali kwambiri kwa nsanja kapena nyumba zazikulu zomwe zimasokoneza kulandira chizindikiro cha TV. Mutha kuthetsa vutoli mwa kukulitsa chizindikirocho pogwiritsa ntchito mlongoti wokhazikika. Pakuthamanga kwambiri komanso kutsika kwambiri, mudzafunika kukonza antenna. Mutha kuyesa kubweretsa mlongoti panja ndikuyesera kupeza malo abwino (mwachitsanzo, kwezani). Ndi khalidwe lochepa komanso mphamvu, pakufunika kukulitsa chizindikiro.

Ngati “friezes” ikuwoneka kawirikawiri, izi zimasonyeza chizindikiro choipa kapena kusintha kwa mlengalenga.

Kusawoneka bwino kwa kanema wawayilesi wa digito – chizindikiro chosawoneka bwino komanso mawonekedwe azithunzi

Ngati mphamvu ya siginecha ili yayikulu ndipo mawonekedwe azithunzi ndi osavomerezeka, mlongoti uyenera kusinthidwa kapena kusinthidwa. Iyenera kutembenuzidwa. Masharubu amagwirizana ndi kutalika kwa mita, ndipo mpheteyo imagwirizana ndi mtundu wa decimeter. Ndicho chimene chiyenera kuzunguliridwa. Muyenera kupeza malo abwino a mlongoti – yendani kuzungulira chipindacho, pitani pawindo. Makoma a konkire olimbikitsidwa, mawindo apulasitiki (mafelemu) amatha kusokoneza kuwulutsa kwa digito.

Chithunzi chosawoneka bwino

Ichi ndi chimodzi mwa mavuto ambiri pakati pa digito TV Intaneti. Mwachitsanzo, TV yokhala ndi diagonal ya mainchesi 40 kapena kupitilira apo ikhoza kukhala ndi chithunzi chosawoneka bwino. Magawo wamba a kanema wawayilesi wa digito amatengera kuwulutsa kwa chithunzi chokhala ndi malingaliro a 720×576. Ngati TV ili ndi diagonal yayikulu, chithunzicho chidzakhala chosawoneka bwino kapena ma pixel adzawoneka. Kwa oyang’anira okhala ndi diagonal yotere, kuwulutsa kwapa TV kwabwino kumafunika – mwachitsanzo, HD (1280×720) ndi Full HD (1920×1080). Pali njira ziwiri zothetsera vutoli:

1. Itanitsani ma phukusi a tchanelo cha HD ndi wopereka chithandizo . Poganizira chithunzi chomveka bwino komanso chokongola pawindo lomwe lili ndi diagonal yaikulu, iyi idzakhala njira yabwino kwambiri.
2. Gwiritsani ntchito TV yakale yokhala ndi diagonal yaying’ono . Ngakhale zoperewerazi, chithunzicho chidzakhala chapamwamba kwambiri.

Kuwoneka kwa kunyezimira (chipale chofewa) pazenera

Mavuto ngati amenewa ndi otheka ngakhale kuonera TV digito. Izi zitha kuchitika chifukwa cha waya wolumikiza STB kapena wolandila ku cholandila TV. Kuti muthetse vutoli, muyenera kugwiritsa ntchito waya wina.

Pali kuzizira, chithunzicho chimasweka

Pankhaniyi, ndi bwino kulumikizana ndi chithandizo chaukadaulo cha wopereka chithandizo kuti akatswiri aphunzire olembetsa kapena zida zamasiteshoni ndikuzindikira komwe kumayambitsa vutoli. Chifukwa cha malangizo omwe alipo, n’zosavuta kuzindikira chifukwa chake televizioni ya digito sikuwonetsa ndikuchotsa. Ngati zonse zomwe zachitika sizinaphule kanthu, mutha kufunsa kwaulere ku malo othandizira ukadaulo mdera lanu ndikuyimbira akatswiri okonza makina kunyumba kwanu.
