Kodi satellite transponder ndi chiyani?

Kanema / kamangidwe kamene kamatsimikizira kuphatikiza ndi
kutumizanso chizindikiro cha satana amatchedwa transponder. Chipangizocho chimatumiza chizindikiro poyankha cholandira. Dongosolo loterolo limatheketsa kufalitsa ma multiplex osiyanasiyana kuchokera ku satana iliyonse ndikupereka mautumiki osiyanasiyana. Pali mitundu iwiri ya ma transponder a satellite: ma transponder osinthika ndi machubu opindika.

Afilisti amagwiritsidwa ntchito kuyimba ma transponder ma frequency omwe amawulutsidwa kuchokera pa satelayiti, ngakhale, kwenikweni, ichi ndi chipangizo chomwe chimawulutsa pafupipafupi.

Ma transponders opindika

Mtundu uwu wa transponder umatenga chizindikiro cha mawonekedwe a microwave. Imakonzanso ma frequency a siginecha yolowera kukhala ma frequency a RF ndikuwonjezera. Chipangizo choterocho ndi choyenera kutumiza zizindikiro za analogi ndi digito. [id id mawu = “attach_3450” align = “alignright” wide = “768”]
Kutumiza kwa chizindikiro cha satellite kumadutsa ma transponder angapo[/ mawu]

Regenerative transponders

Zida zoterezi zimagwiranso ntchito zonse za transponder yokhotakhota ya chitoliro, koma pamenepa pali kutembenuka kwafupipafupi ndi kuwonjezereka kwa mphamvu ya chizindikiro. Kuphatikiza pa ntchito za 2 izi, transponder yobwezeretsa imachita ma frequency spectrum demodulation komanso kuchira kwazizindikiro ndikusintha. Transponder imagwira ntchito ziwiri. Amalandira ndi kutumizanso chizindikirocho, pamene machitidwe amakono amayeretsa momwe angathere kuchokera ku phokoso losafunika.

Mfundo ya ntchito

Satellite transponder ndi gulu lazigawo zomwe zimayikidwa pa satelayiti, zomwe zimapangidwira kuti zizilandira ndi kutumiza chizindikiro pafupipafupi. Imafanana ndi gawo la satellite lomwe lili ndi tinyanga.

Setilaiti iliyonse imakhala ndi ma satelayiti angapo omwe amawulutsa ma frequency angapo. Chifukwa cha kukhazikitsidwa kwa ukadaulo woulutsirawu, kuchuluka kwa ma satelayiti pa satelayiti imodzi kwachulukirachulukira, kuchokera pagawo limodzi la orbital ndizotheka kuwulutsa pafupifupi tchanelo chikwi. Mfundo yogwiritsira ntchito satellite transponder ndi motere – chizindikiro cha TV cha satellite, chomwe chimakhazikika pa mlongoti wa transpoder, ndipo chifukwa cha mawonekedwe ake amtundu wa mbale, amapangidwanso ngati kuchokera pagalasi kupita kumalo enaake – mbale yolandira wogwiritsa ntchito. , yomwe imatumiza chizindikiro kwa wolandirayo, yomwe imasandulika kukhala TV yowerengeka. Zigawo zazikulu za transponder ndi:

• mlongoti kulandira chizindikiro – chipangizo chachikulu cholandirira chizindikiro cholumikizira;
• amplifier mphamvu – kumakulitsa mphamvu ya siginecha analandira pa mlingo wokwanira;
• duplexer (frequency separation fyuluta)  – chipangizo chopangidwa kuti chilinganize kulumikizana kwapawiri kwa wailesi pogwiritsa ntchito mlongoti umodzi wamba polandila ndi kutumiza chizindikiro;
• purosesa yowongolera – kusankha ndikusintha ma frequency azizindikiro.

Ma Transponder amakanema satana kuti muwonere kwaulere satellite TV mu 2021

Pali mayendedwe a satelayiti a TV omwe mungawonere kwaulere, pali mayendedwe otsekedwa ndi kiyi ya BISS yokhazikika. Makanema mu encryption ya BISS amatsegulidwa mwaulere pogwiritsa ntchito emulator yamkati ya wolandila. Pazochitika zonsezi, muyenera kukhala ndi tebulo laposachedwa la ma frequency ndi ma transponder omwe ali pafupi kuti mukhazikitse kanema wa satellite. Gome lapano la transponders likuperekedwa pansipa, njira yolembera, ma frequency amaperekedwanso, transponder yotsekedwa kapena yaulere ikuwonetsedwa. Mndandanda wamakanema apakanema ndi ma transponder a 2021 a satellite Eutelsat 36B, 36.0E:

Kukonzekera kwa Broadcast

Tiyerekeze kuti tasankha pa satelayiti. Mwachitsanzo, iyi ndi Eutelsat 36B, 36.0E. Ndikofunikira kukhazikitsa mbale ya satellite ndikugwira chizindikiro, kudziwa mtundu wa chizindikirocho. [id-caption id = “attachment_3195″ align=”alignright” width=”688″]
Ubwino wa siginoyi umawunikidwa pa chipangizo cha TV[/ mawu ofotokozera] Momwe mungayikitsire dishi la satellite ndi kuyika TV ya satellite mwatsatanetsatane pa ulalo . Gawo loyamba ndi “Frequency” – titha kutenga ma frequency ofunikira kuchokera patebulo la transponders ndi ma frequency. Poyamba, muyenera kumvetsetsa kuti ma frequency awa akuphatikizidwa. Timayendetsa mofunikira pogwiritsa ntchito chowongolera chakutali.
Mtundu wa polarization umayikidwa mugawo lomwelo (chilembo pafupi ndi icho). Oyima kapena yopingasa (“H”, “V”). Onse olandila amakono amathandizira pafupifupi mitundu yonse ya polarization. Gawo lachiwiri ndi “Speed/SR”. Deta yalowetsedwa mugawoli – SR (chizindikiro) ndi FEC (kukonza zolakwika). SR – mtengo uwu ndi wofanana ndi kuchuluka kwa chizindikiro chomwe wolandila wanu amathandizira. Koma olandila amakono a satana amathandizira mitundu yonse ya parameter iyi, chifukwa chake izi zitha kudumpha. Mtengo wa FEC– mukamagwiritsa ntchito mabokosi amakono a satellite set-top, parameter iyi imathanso kudumpha. Mzere wachitatu “Dzina la Channel” ndilo dzina la satana, chizindikiro chomwe chimafalitsidwa kuchokera ku transponder inayake. Mwachitsanzo, dzina la TV kapena wailesi, kapena dzina la utumiki wa pa Intaneti. Gawo lachinayi ndi “BISS/ID”. Mtundu wa encoding ndi kupezeka kwake / kusakhalapo kumawonetsedwa ndi gawoli.
Mwanjira ina, ngati pali mtundu wina wa encoding mu transponder, ndiye kuti ntchitoyi imalipidwa. Kukhazikitsa zida za satana muzochitika zamakono, muyenera kudziwa mfundo zitatu – pafupipafupi, mtundu wa polarization, mtundu wa encoding. Kodi ndingapeze kuti ma frequency ndi ma transponder a tchanelo cha satellite? Zamakono pakali pano (pakati pa 2021) pamwamba ndi pansi palemba, ngati mukufuna zaposachedwa, pali njira ziwiri. Kuchokera m’mabuku osindikizidwa a mutu womwe mukufuna, kapena pa intaneti. Ngati njira yoyamba ili yoyenera, mwachitsanzo, kwa anthu akumudzi, ndiye kuti m’pofunika kufufuza kuti magaziniyi yachedwa kwambiri, chifukwa ma satellites amasintha maulendo ndi transponders nthawi ndi nthawi. Pa intaneti, ndikwanira kuyendetsa pempho lotere “tebulo la satellite transponders”.Tsitsani tebulo

Satellite TV transponders kuchokera MTS

Ma frequency ndi ma transponder a satellite TV kuchokera ku MTS . Ma frequency a MTS pa satellite ya ABC-2:

Kukhazikitsa makanema apa TV pa MTS TV kutha kuchitidwa zokha kapena, ngati mukufuna, izi zimachitika ndi wolembetsa mumachitidwe amanja. Pomaliza, muyenera kuyendetsa nokha ma frequency. [id id mawu = “attach_3200″ align=”aligncenter” wide=”512″] Kulumikizidwa
ndi siginecha ya satellite yochokera ku MTS TV[/mawu] Mawu achidule pakukhazikitsa TV ya satellite kuchokera ku MTS:

• Konzani mlongoti woperekedwa pakhoma la nyumbayo m’njira yoti mitu ikhale pakona yofunikira kwa transponder.
• Ikani chotchingacho kuti mbaleyo ikhale pakona ya 30 ° mpaka yopingasa.
• Azimuth ya kupendekeka kwa “mlongoti” iyenera kukhazikitsidwa ndi 1 °.
• Ikani mbale pakona ya 137 °.
• Yatsani TV ndikuyang’ana mtundu wa chizindikiro.
• Ngati khalidwe lofunikira palibe, m’pofunika kuzungulira mlongoti ndi digiri 1 ndikuyang’ana khalidwe la chizindikiro pa sitepe iliyonse.
• Ngati muli ndi “TV yochokera ku MTS”, ndiye kuti ma TV ayenera kukhazikitsidwa okha.
• Ngati mukufuna kuyimba TV nokha, gwiritsani ntchito transponder data yomwe yaperekedwa pamwambapa.

Malangizo atsatanetsatane amomwe mungakhazikitsire mbale ya satana kuchokera ku MTS.

Kupanga koyamba

Musanagule zida za satellite TV kuchokera ku MTS, muyenera. Yang’anani kuthekera koyika zida. Pazifukwa izi, ndizotheka kugwiritsa ntchito pulogalamu yaulere yamafoni yomwe imatha kutsitsidwa kuchokera ku App Store kapena Play Market (https://play.google.com/store/apps/details?id=com.esys.satfinder&hl=en&gl =US). Pulogalamu yotchedwa “SatFinder”, mutayiyika pa foni yanu, zidzatheka kuzindikira ma satellite omwe akupezeka kudera linalake.
Pulogalamuyi imakupatsani mwayi wodziwa komwe ma satelayiti ali, komanso ikuwonetsani momwe mungayikitsire mlongoti. [id id mawu = “attach_3101” align = “aligncenter” wide = “660”]
