Set-top box egaziya obusobozi bwa ttivvi. Ttivvi enkadde ziyinza obutakkiriza bubonero bwa DVB-T2. Emikutu egy’omulembe giweebwa mu nkola eno.

Mu mbeera eno, kirungi okuyunga set-top box esobola okuggya signal ya digito n’egikyusa mu analog. Waliwo ne set-top box za DVB-C ( cable TV ), DVB-S ( satellite TV ) ne set-top box nga zirina enkola z’emirimu ezigatta. Smart set-top boxes ( TV-Box ) zirina okuteekebwa mu kiti eky’enjawulo. Basobola okuyunga ddala ttivvi yonna ku yintaneeti. Era, tewerabira ku waya ya antenna: obuwanvu bwayo bulina okupimibwa nga bukyali, nga buweereddwa margin entono for obusobozi bw’okukola maneuvre. Ate era, ddala set-top box zonna zeetaaga cable okuyungibwa butereevu ku TV yennyini. Kino kiyinza okuba cable ya HDMI, mu mbeera ya TV empya, oba RCA oba SCART, mu mbeera ya TV ezisukka emyaka 6.

.

Okuzuula ekika kya cable gy’olina okuyungibwa, olina okutunuulira emabega wa ttivvi n’okebera oba waliwo interfaces ezeetaagisa oba okuzikebera mu biragiro bya ttivvi.

Obunene bw’okutuusa TV set-top box – cable

Mu kiti, ng’oggyeeko set-top box yennyini, osobola okulaba waya eziwerako ez’okuyunga ku ttivvi ez’enjawulo. Okugeza, ekitabo kiyinza okubaamu waya ya HDMI, RCA, SCART ne S-Video

Ku lwa HDMI interface waliwo enkyusa eziwerako:

1. HDMI 1.2 – ekusobozesa okufulumya ekifaananyi kya FHD.
2. HDMI 4 – ekusobozesa okulaga ebifaananyi bya 4K ku frame rate ya 30 fps.
3. HDMI 0 – ekusobozesa okufulumya ebifaananyi bya 4K ku frame rate ya 60 fps.

HDMI ye nkola ya digito ekusobozesa okuyunga set-top box ku ttivvi empya, era nga nayo erina layini z’amaloboozi ezizing’amya. Ku ttivvi enkadde, waliwo analog SCART interface, eringa ekiyungo ekigazi eky’enjuyi ennya, S-VIDEO, eringa ekiyungo ekiddugavu nga kiriko pulaagi wakati ne RCA, eringa ssatu eza langi ez’enjawulo (emmyufu, enjeru ne… emmyufu) pulagi za tulip.

Bw’okozesa emu ku nkola zino, olwo obulungi obusinga obunene bujja kuba 768 ku 576 pixels, era frame rate ejja kuba ekoma ku 25 fps.

Bokisi za TV nnyingi zirina emikutu gya USB egikusobozesa okuyunga okugeza USB flash drive n’okuzannya multimedia yonna (omuziki, vidiyo, ebifaananyi). Okuzannya ebirimu bya FHD ku 1920×1080, flash drive yonna eya USB 2.0 emala, naye ku 4K resolution, nga eno eri 3840×2160, weetaaga USB 3.1 second generation (gen2) drive ng’erina bandwidth ya gigabits ezitakka wansi wa 20 buli sikonda.
Era kirungi okujjukira nti remote control yokka y’erimu ne set-top boxes ez’okufuna emikutu gya ttivvi egya digito. Naye ekitabo ekirimu set-top boxes eziweereza signal ya satellite nakyo kirimu set ya waya ezeetaagisa okuyunga antenna, ne decoders.

Ebikozesebwa ebirala ku set-top boxes

Bw’oba ​​tokolagana na set-top boxes era nga tomanyi ngeri ya kugisengeka bulungi, olwo osobola okugula set ya set-top boxes ne wireless keyboard nga olina mouse. Seti ng’ezo zitera okusangibwa ne mmotoka ez’omutindo ogwa waggulu, ezitandikira ku 5000 rubles. Mouse ejja kukuyamba okutambula amangu mu console interface, ate keyboard ejja kukuyamba okuwandiika amangu ebiwandiiko. Ekirala, ebikozesebwa ebirala mulimu ebika by’emiguwa egy’enjawulo egy’okugaziya, adapta, splitters ne splitters, ebiyinza okuba eby’omugaso mu kuyunga ttivvi eziwerako mu kiseera kye kimu. Engeri y’okuyunga ttivvi bbiri ku set-top box emu eya digito Tricolor :

Enkomerero endala eya waya ya HDMI erina okuteekebwa mu set-top box yennyini. Omukutu gwa HDMI gutera okubeera emabega wa set-top box nga bwe guli. Bw’oba ​​ogenda okulaba ebirimu mu 4K resolution, olwo olina okutunuulira specifications za set-top box ne TV omanye oba biwagira resolution eno. Era kyetaagisa okukebera omulembe gwa cable yo eya HDMI, okuva omulembe bwe gusalawo oba interface esobola okutambuza ebirimu mu resolution eyagala ku frame rate eyeetaagisa.

Teekamu ttivvi yo ne set-top box.

Buli kimu bwe kiyungiddwa, ssaako set-top box okuva ku remote control oba okuva ku button eriko, bwe wabaawo ku case.

Ggyako ttivvi n’olonda set-top box ng’ensibuko ya siginiini. Okukola kino, nyweza bbaatuuni ya Input (era eyitibwa Source – output oba source) era olonde omukutu gwa HDMI oguyungiddwa.

Singa set-top box eyungiddwa bulungi, ojja kulaba eddirisa ly’ensengeka ezisooka eza set-top box. Bw’olaba obubaka obukwata ku butabeerawo siginiini oba ssirini enjeru, olwo kakasa nti waya ya HDMI ne set-top box yennyini bikola, era era kebera oba set-top box eyungibwa ku ttivvi.

Ttivvi enkadde

Ekitabo ekyasooka kyannyonnyola emitendera gy’okuyunga set-top box ku ttivvi empya ng’oyita mu waya ya HDMI. Bw’oba ​​oyunga set-top box ya ttivvi ya digito ku ttivvi enkadde, olina okufaayo ku kiyungo ky’ogenda okuyunga set-top box ku ttivvi.

1. Ebiseera ebisinga, okuyungibwa kukolebwa nga kuyita mu kiyungo kya RCA , ekiringa pulagi ssatu eza kyenvu, emmyufu n’enjeru – tulips. Yunga enkomerero esooka eya waya ku ttivvi ne ku set-top box. Kakasa nti langi z’ebiyungo ku set-top box oba TV zikwatagana ne langi ya pulagi eyungiddwa . Singa langi teziwandiikiddwa ku set-top box oba ku ttivvi, olwo ssaako pulagi mu ngeri ey’ekifuulannenge okutuusa lw’onoofuna ekifaananyi oba eddoboozi. Singa oyingiza pulagi mu socket enkyamu, olwo tewali kijja kubaawo – tekirina bulabe bwonna gy’oli n’ebyuma.
2. Oluusi olina okuyunga ng’oyita mu kiyungo kya SCART . Okukimanya kyangu: SCART eringa ekiyungo ekiwanvu ekya nneekulungirivu nga munda kirimu pulagi empanvu. Enkizo yaayo eri nti esobola okuyungibwa ku ludda lumu lwokka olw’enkula yaayo etali ya kigero, kale kizibu nnyo okukola ensobi ng’oyunga set-top box ku ttivvi.
3. Enkola eyokusatu ey’okuyunga set-top box ku ttivvi ye S-Video , ekiyungo ekyekulungirivu ekitera okuba ne langi ya kyenvu oba enjeru. Kyangu okutabula n’ekiyungo kya RCA, kale bw’oba ​​tokakasa kuyungibwa kutuufu, olwo tunuulira ebiragiro bya ttivvi ne set-top box era okakasa ekifo ekiyungo kino we kiri.

Waliwo n’embeera nga set-top box erina HDMI output yokka, ate TV enkadde erina analog outputs zokka. Mu mbeera eno, olina okugula converter ekyusa signal ya digital okudda mu analog. Ebimu ku bikyusa bino biyinza okwetaaga amaanyi ga USB, agayinza okufunibwa ng’oyunga ekikyusa ku mulyango gwa USB ku set-top box yennyini. Engeri y’okuyunga set-top box ya digito ku ttivvi ya LG n’okutuunya emikutu: https://youtu.be/LuMUNZTLb8s

Engeri y’okuyunga set-top box ku ttivvi eziwerako mu kiseera kye kimu

Okuyunga ttivvi eziwera mu kiseera kye kimu, olina okugula ekyuma ekigabanya waya za HDMI. Splitter ng’eyo egula ruble nga lukumi. Ekoppa siginiini efuluma n’egiweereza ku mikutu gyayo gyonna egya HDMI. Bw’oba ​​okozesa cable ya RCA, weetaaga divider ku signal ya analog, egula okuva ku rubles 400. Omusingi gw’enkola yaayo gufaananako ne splitter ya HDMI, naye omutindo gusingako awo.

Ebizibu ebiyinza okubaawo n‟ebigonjoolwa

1. Ekifaananyi kibula, kifuuka bbugumu oba “kimenya” . Kino kiva ku kifo ekikyamu antenna gy’eri n’okuyungibwa kwayo ku set-top box. Gezaako okutambuza antenna mu kifo eky’enjawulo olabe omutindo gwa siginiini bwe guli.
2. Set-top box ekola, naye bw’ogezaako okutandika omukutu, “oluyoogaano olweru” oba screen enjeru eraga mu kifo ky’ekifaananyi . Singa emikutu gyali gikola, naye kati tewali kifaananyi, olwo emirundi gy’emikutu gisinga kuteekebwa mu bukyamu. Kino oluusi kibaawo oluvannyuma lw’okulongoosa firmware ya set-top box oba okugwa kw’amasannyalaze ekivaamu okuggalwa nga tekunnabaawo. Mu mbeera eno, okuddamu okulongoosa (okunoonya) emikutu kijja kuyamba.
3. Ekifaananyi kifuuse kifu oba kizibu . Obuzibu buno buva ku kulonda obubi resolution ku set-top box, nga eno eri wansi okusinga resolution ya TV.
4. Set-top box tesobola kuzannya firimu ekwatibwa ku flash drive. Okusinga, set-top box tesobola kuzannya fayiro za nkola firimu mw’ekwatibwa. Okugeza, firimu oba fayiro ya vidiyo endala yonna erina okuzannyibwa ku TV set-top box yakwatibwa ku flash drive mu .mov extension, set-top box ky’etasobola kuzannya olw’obukwakkulizo bwa software obwateekebwawo omukozi ensonga emu oba endala. Okugonjoola ekizibu kino, olina okukyusa fayiro ya vidiyo eyasooka okudda mu ekyongerwako ekiwagirwa ng’okozesa pulogulaamu ey’enjawulo oba empeereza ey’oku yintaneeti, oba okuwanula fayiro endala eriko ekyongereza ekiwagirwa. Okusobola okumanya oba set-top box yo ewagira extension entongole, soma ebiragiro byakyo, ebyandibadde mu package. Kirungi okukozesa okunoonya okw’otoma emikutu gya TV. Mu nkola y’okuteekawo, set-top box yennyini ejja kukebera frequency zonna n’okulonda ezo emikutu gya TV kwe giragibwa. Singa auto tuning teyayamba, wandibadde okozesa manual channel search. Mu mbeera eno, olina okukyusakyusa frequency mu ngalo n’onoonya ezisaanira. Emirundi omukutu ogutali gumu gye gukolebwamu osobola okugusanga ku mukutu gw’omukutu ogwo.
