Eky’okukola singa emikutu gya ttivvi za digito tegiraga era lwaki kino kibaawo

Omutindo n’obulungi bw’okuweereza emikutu gya digito bisobola okwonooneka olw’ebyuma okulemererwa. Toyanguwa kuyita mukama n’okuwa ssente. Oluusi ekizibu kigonjoolwa nga tewali bakugu.

Bizibu ki ebikosa okulaga emikutu gya digito

Olukalala lw’ebizibu ebivaayo lulimu okulemererwa okutera okubaawo buli mukozesa ow’okubiri kw’asanga. Ebikozesebwa mu kuweereza ku mpewo n’okusembeza abantu mu ngeri ya digito bikoleddwa eri abantu bangi, kale okumenya okutali kwa bulijjo tekuliimu. Naye, waliwo ebiseera nga:

• okunoonya mu mbeera ya otomatiki tekwazudde mukutu gumu;
• si buli kimu ekiweebwa ku mpewo mu kitundu kyo kye kyazuulibwa;
• emikutu girina ebikoppeddwa;
• set- top box eyungiddwa, naye menu telabika ku screen oluvannyuma lw’okunyiga ekisumuluzo ekikwatagana ku remote control;
• menu ya set-top box eri ku screen, naye bw’otandika okuteekawo, obubaka “No signal” bulabika;
• tewali kabonero konna, era tewali pulogulaamu yonna eraga;
• autosearch teyazudde kintu kyonna, obubaka ku screen: “Tewali mpeereza”;
• ekifaananyi kifuuka bbugumu ku fuleemu emu, ne kigwa mu cubes, eddoboozi “lifuumuuka”;
• ekifaananyi ekitali kitegeerekeka, omutindo gw’amaloboozi omubi oba tewali;
• ekifaananyi ekiddugavu n’ekyeru ku ssirini ya ttivvi eya langi.

Lwaki tebalaga mikutu gya digito?

Okulemererwa, ebyuma bwe bitafuna era nga tebikola decode signal ya digital, kulina ensonga eziwerako. Waliwo ebimu ebiraga nti kyetaagisa okuddaabiriza, okukyusa ebyuma, oba okukakasa okuyungibwa okutuufu n’okutereeza.

Mu kunoonya ekivaako, genda okuva ku kyangu okudda ku kizibu. Okulemererwa oluusi kyangu okuzuulibwa, era tekikwetaagisa budde bungi na kumanya okusobola okukimalawo. Bw’oba ​​ofiriddwa ekifaananyi, oba emikutu tegitungibwa, okusookera ddala buuza oba baliraanwa bo, ab’enganda oba b’omanyi ababeera mu kitundu kyo balina ku mpewo.

Okulemererwa kwa antenna

Okulemererwa
kwa antenna tekutera kubaawo. Ensonga eziviirako kino kwe kwonooneka kw’ebyuma, okukosebwa kw’embeera y’obudde (okumyansa, obunnyogovu, empewo ey’amaanyi), bwe kiba nga kya bweru. Oba okulemererwa kwa signal amplifier, bwe kiba nga waliwo.

Ebizibu ku waya n’okuyunga

Singa ebyuma biyungibwa mu bukyamu, ensobi zino wammanga ze zitera okubeerawo:

• socket enkyamu yakozesebwa okuyunga pulagi;
• set-top box ey’ebweru teyungiddwa bulungi;
• Ebyuma tebiyungibwa ku masannyalaze, era ebiraga amasannyalaze ku set-top box oba ttivvi tebiyaka.

Ebizibu bya Hardware

Okufuna siginiini ya digito, antenna ne tuner ey’ebweru oba ezimbiddwamu byetaagibwa. Okulemererwa okwa bulijjo okw’ebyuma byonna kusoboka:

• console okukola obubi ;
• low-quality receiver firmware , enkyusa ya pulogulaamu ya signal decoding eyali evudde ku mulembe, firmware teyamalirizibwa bulungi oba teyamalirizibwa;
• ebizibu by’okufuna siginiini , – obulagirizi obutatuufu bwa antenna okutuuka ku munaala gwa repeater, okutaataaganyizibwa mu kkubo lya siginiini (ebizimbe, engule z’emiti, obusozi);
• okuddamu okuteekawo ensengeka, firmware ya hardware evudde ku mulembe (esangibwa ku TV za LG);
• omulimu gw’okuddaabiriza, mu bwangu oba  okukomya okuweereza ku mpewo okutegekeddwa abaddukanya ttivvi za digito olw’okuzzaawo oba omulimu ogutegekeddwa.

Ebizibu mu kufuna siginiini

Decimeter frequency range ku digital broadcasting kwe kukolebwa yeetaaga ku direction ya antenna reception eri repeater tower. Okuyingirira kwonna mu kkubo lyayo kuleeta okufiirwa mu mutindo gwa siginiini efunibwa. Mu bino mulimu bino wammanga:

• Obudde obubi . Enkuba, okubwatuka, omuzira, ekifu bikola emabega era ne bitaataaganya siginiini ewereddwa okuva ku munaala.
• Ebiziyiza eby’omubiri (okuyingirira) mu ludda lw’akabonero.
• Okufuna siginiini okuva ku minaala ebiri oba okusingawo ebiriraanye ebiddiŋŋana .

Emikutu gya digito tegiraga, olw’okuba nti tewali signal ya DVB T2 – eky’okukola: https://youtu.be/iZn_YUFZTtw

Eky’okukola singa tewabaawo mikutu olw’ensonga emu oba endala

Nga tonnatuukirira mpeereza, kakasa nti okumenyawo tekusobola kulongoosebwa ku bubwo. Tuukirira abakugu ng’okugezaako kwonna okugumira embeera ku lwabwe kulemereddwa.

Ttivvi enkadde tezirina kiyungo kya cable emmyufu ekitegeeza nti ekuba eddoboozi lya mono. Okuyungibwa kwayo tekyetaagisa, naye ebisigadde birina okuyungibwa obulungi.
4. Singa antenna tefuna siginiini ya UHF, gikyuse okukebera .
5. Kyuusa ensibuko ya siginiini ku ttivvi . Nywa ku bbaatuuni ya “SOURCE” ku remote control ya TV. Ku model ezimu, eno ye button y’okuyingiza vidiyo – enzirugavu erimu akasaale munda oba emu ku nkola: “AV”, “AV / TV”, “INPUT”. Ebika bya TV eby’enjawulo okuva mu bakola eby’enjawulo biyinza okuba n’ensonda za vidiyo eziwera. Zilonde emu ku emu okutuusa ng’emmeeza ya menu ya digital tuner efulumye.
6. Ggyako enkola ya langi ya PAL oba SECAM .
7. Kakasa nti firmware etuukana n’omutindo gw’okuweereza ku mpewo . Button “Menu” ku set-top box, olwo “Installation” oba “Settings” okusinziira ku model ya set-top box n’oyo eyagikola. Mu Russia ziweereza ku mpewo mu nkola ya DVB-T2. Singa omutindo guba gwa njawulo, gukyuse.
8. Reflash ebyuma ng’obiyunga ku PC era osooke owanule firmware version empya ku mukutu gw’abakola ebyuma. Ebifo ebikola ku mpeereza biwa empeereza eno singa wabaawo obuzibu.
9. Gula ebyuma ebituukana n’omutindo gw’okuweereza ku mpewo .

Okukebera omutindo gw’okusembeza n’okubeerawo kwa siginiini y’emikutu gy’okuweereza ku mpewo

Si mutindo gwa kifaananyi kyokka ku ttivvi, wabula n’ensengeka y’emikutu esooka esinziira ku kubeerawo kw’okuweereza n’obukwakkulizo bw’okukifuna. Okuzuula ekizibu kino kye kisalawo okwongera okukola. Kola bino wammanga:

1. Kebera amaanyi ga siginiini efunibwa . Nga onyiga bbaatuuni ya “INFO” ku remote control ya set-top box (emirundi 2-3, okusinziira ku model ya set-top box), fuluma mu menu y’amawulire agakwata ku siginiini. Yawukana ku bika bya TV okuva ku bikola eby’enjawulo, naye bulijjo erina minzaani ya level. Osobola okulaba ekifaananyi kye kimu ng’okola “Manual Search”.
2. Kebera ku Maapu y’amawulire ag’okuweereza ku mpewo agakwata ku ngeri y’okuweereza ku mpewo ey’abaddukanya emirimu gy’okuweereza ku mpewo . Singa okuweereza ku mpewo kuyimirizibwa okumala akaseera, kyusa tuning n’okunoonya emikutu mu kiseera ky’okukola okutebenkedde.
3. Teekateeka antenna mu ludda lw’omunaala gwa repeater . Ekiraga ensengeka entuufu ye minzaani y’amaanyi ga siginiini ag’okwongera. Singa ensengeka teyayamba, olina okukyusa ekifo antenna w’eteeka oba okugiteekamu amplifier.
4. Kola okunoonya emikutu mu ngalo okusinziira ku bipimo by’okuweereza okuva ku minaala mu kitundu kyo . Data osobola okugifuna ng’olonda ekitundu kyo ku Maapu ya ttivvi ekwatagana.
5. Kebera waya eva mu antenna n’amaaso okulaba oba efunye ebizimba, okwonooneka . Pima obuziyiza bwa insulation nga okozesa ohmmeter. Wakati wa kondakita ow’omu makkati n’olugoye, omuwendo guba kumpi n’obutakoma, ku kondakita ow’omu makkati n’olugoye ku nkomerero zombi guba kumpi ne ziro, singa ekipimo ng’ekyo kibaawo.
6. Kyusa waya eva ku antenna okudda ku mpya . Resistance ya cable entuufu eri 75 ohms.

Emikutu gya ttivvi za digito, tewali siginiini, era ekifaananyi kimenyeka – ebivaako n’okubimalawo: https://youtu.be/4fRdee5g6xs

Autotune nga bwe kiri

Emikutu gya ttivvi egya digito gitereezebwa mu ngeri ey’otoma. Ensengeka y’ebikolwa ku byuma eby’enjawulo ya njawulo katono mu mannya g’ebintu ebiri mu menu, oba waliwo enkyusa y’Olungereza yokka ku byo. Okutandika okunoonya okw’otoma:
