Ungaxhuma kanjani ibhokisi le-digital set-top ku-TV endala? Ithelevishini yedijithali, eyangena esikhundleni sokusakazwa kwe-analogi, ithola ukuthandwa kakhulu unyaka nonyaka. Isithombe esisuka kumsakazi siya kumsebenzisi sidluliselwa ngokulungiswa okuphezulu kwe-Full-HD. Abasebenzisi bangaxhuma amabhokisi e-digital set-top ngisho nama-TV amadala. Asikho isidingo sokuphendukela kochwepheshe. Ungenza lo msebenzi uwedwa. Ngezansi kunezinketho eziyinhloko zokuxhuma, izinkinga ezingenzeka kanye nezici zezilungiselelo zomamukeli.

Okudingayo ukuze uxhume ibhokisi le-set-top ku-TV endala

Ngaphambi kokuqala umsebenzi, umsebenzisi udinga ukunakekela ukuthola izinto ezidingekayo, okungukuthi ishuna yokuguqula isignali yokufaka ibe yifomethi ye-DVB / izintambo zokuxhuma zesixhumi se-tulip.

Qaphela! Kumamodeli ohlobo oludala, lapho i-kinescope ifakiwe, uzodinga i-adaptha ekhethekile kanye ne-modulator ye-RF.

Kuye ngohlobo nemodeli kachwepheshe/ishuna, kungase kudingeke ukufakwa okwengeziwe kwe-antenna yasendlini.

Izinketho zokuxhuma

Ngezansi ungathola izindlela eziyinhloko zokuxhuma isamukeli se-DVB T2 ku-TV endala.

Ukuxhumana nge-RCA tulips

Le ndlela ibhekwa njengelula kakhulu. Iqoqo lezixhumi ze-RCA livame ukubizwa ngokuthi “i-tulip” / “bell”. Ukuze uxhume umamukeli ku-TV ephelelwe yisikhathi nge-“tulip”, umsebenzisi uzodinga ukunakekela:

1. Vala i-TV nesamukeli kumasokhethi.
2. Ukuxhuma izixhumi zekhebula kumasokhethi afanelekile. Kubalulekile ukunaka ilebula. Izimpawu zombala kumapulaki e-RCA kufanele zifane nezimpawu zombala zamasokhethi oxhuma kuwo. Uma kunezixhumi ezimbalwa kuphela, kubalulekile ukuxhuma ophuzi nomhlophe. Ungenza ngaphandle kwekhebula elibomvu.
3. Ikhebula le-antenna lixhunywe ku-set-top box.
4. Vula i-TV, uye kumenyu bese ukhetha imodi ye-AV, ngemva kwalokho baqale ukusetha iziteshi ebhokisini le-digital set-top.
5. Amashaneli agcinwe kumemori ye-set-top box.

Uma ulandela lolu hlelo, umsebenzisi ngamunye uzokwazi ukuxhuma ngokuzimela ishuna ye-TV ku-TV yakhe.

Nge-SCART

Isixhumi esibonakalayo se-SCART sahlala singesaseYurophu eyinhloko isikhathi eside, ngakho-ke uma unesixhumi esifanele, ungasisebenzisa ngokuphepha ukuze uxhume ishuna ye-TV.
Izici zokuxhuma i-set-top box nge-SCART:

4. Ngemva kwalokho, vula amandla bese ushintshela i-TV kumodi ye-AV.

Esigabeni sokugcina, bamatasatasa ekusetheni ibhokisi le-set-top ukuze bathole isignali yethelevishini.

Xhuma ngesixhumi se-antenna

Kuma-TV amadala afana ne-Horizon / Beryozka / Record, azikho izixhumi zesiginali ye-AV. Kulesi simo, ungasebenzisa okokufaka kwe-antenna kwesamukeli esidala saseSoviet. Kodwa-ke, kufanelekile ukukhumbula ukuthi enye inkinga ingase iphakame: iningi lamashuna e-TV alikusekeli ukuphuma kwamasignali amaza aphezulu kuphaneli ye-TV. Inani elincane lama-TV anokufakwa kwe-antenna. Ingxenye ethile kuphela yamamodeli athengiswayo ekwazi ukusakaza isignali ye-RF ekhishwe ikhodi. Nokho, ungathukutheli. Ochwepheshe bayeluleka kulesi simo ukuthi basebenzise imodulator ye-RF yangaphandle.

Izici zokuxhuma i-modulator ye-RF

Ngesikhathi sokuxhuma, kufanele unamathele kuhlelo olulandelayo:

1. I-antenna ixhunywe kukhonsoli.
2. Bese, imoduli ye-RF ixhunywa kokunamathiselwe. Ukuze wenze lokhu, sebenzisa ikhebula le-adaptha.
3. Imoduli ixhunywe ku-antenna okokufaka kwe-TV.

Amasiginali aphezulu e-analogi anamashaneli edijithali azoza ku-TV. Inqubo yokusetha idivayisi ukuze yamukelwe ifana nokusetha ukwamukela kwezinhlelo ze-TV ze-analogue terrestrial. Qaphela! Uma siqhathanisa isithombe nekhwalithi yomsindo nemoduli ye-RF kanye noxhumo lwe-AV, lapho-ke kuzoba phezulu. Ezimeni lapho kusetshenziswa i-TV yohlobo lwe-UPIMCT, kungenzeka ukuthi uphahlazeke kuyunithi ye-SMRK, lapho isignali ye-TV ihlukaniswa ngevidiyo / umsindo ukuze kuxhunywe izixhumi zanoma yiluphi uhlobo koxhumana nabo. Ngaphandle kokuba lula kwalo msebenzi, umsebenzisi kufanele okungenani abe nolwazi oluncane mayelana nesakhiwo se-TV.
Kunezimo lapho i-set-top box ingenakho okokukhiphayo okufanele noma izixhumi ku-TV neshuna ye-TV zingahlangani. Kulesi simo, kuhle ukuthi unakekele ukushintsha ibhokisi le-digital set-top noma ukusebenzisa ama-adaptha.
Phakathi kwezimo eziyinhloko zokusebenzisa ama-adaptha, kufanelekile ukugqamisa okulandelayo:

1. Esimeni lapho i-set-top box inokukhipha kwe-HDMI kuphela, kutuswa ukusebenzisa isiguquli se-RCA. Kufanele kukhunjulwe ukuthi ikhwalithi yesithombe nomsindo izoba ngaphansi kancane. Iziteshi zamafrikhwensi aphezulu ngeke ziboniswe, nokho, isiginali izoboliswa ngendlela efanele ibe izikhombisi-ndlela ezi-3 ezindala zibe umsindo wezipikha nevidiyo kwesokudla/kwesokunxele.
2. Uma usebenzisa i-plasma, i-LCD TV eyakhishwa ngasekuqaleni kwawo-2000, uzodinga ukuthenga ama-adaptha e-HDMI-VGA ukuze uxhume ibhokisi elibekwe phezulu, ngoba isixhumi sevidiyo kulawa madivaysi sidala (VGA). Ukuze udlulisele umsindo kuphaneli ye-TV, udinga ukunakekela ukuthenga intambo eyengeziwe ehlukile (Jack 3.5 mm).

Ezimweni lapho kunenkinga yokuhambisana phakathi kwe-S-Video ne-SCART, ochwepheshe bayeluleka ukusebenzisa i-adaptha. Ingxenye eyinhloko yamamodeli isekela ukuphuma kwe-RCA (i-tulip kathathu).

Indlela yokusetha umamukeli ngemva kokuxhumeka

Ngemuva kokuthi ishuna ixhunyiwe, udinga ukuqala ukuyisetha. Ukuze wenze lokhu, umsebenzisi uzodinga:

1. Usebenzisa isilawuli kude ngena kumenyu. Sicela uqaphele ukuthi amamodeli amaningi we-TV asekela amarimothi aku-inthanethi.
2. Yiya esigabeni esithi “Izilungiselelo Zesiteshi”.
3. Khetha izwe.
4. Cacisa izinga elifanele (isb i-DVB-T2).

Iziteshi zishunwa ngokuzenzakalelayo. Kubalulekile ukuthi ungakhohlwa ngesidingo sokulondoloza izinguquko ezenziwe.
Uma imodi ezenzakalelayo ingavuli, ungakhathazeki. Ungakwazi ukusetha ikhonsoli ngokwakho (mathupha). Kwalokhu:

• iya esigabeni sezilungiselelo zesiteshi bese usetha imingcele oyifunayo;
• chofoza imodi yokusesha ngesandla;
• faka idatha enembile/setha isiteshi ngasinye usebenzisa indlela yokukhetha imvamisa.

Esigabeni sokugcina, izinguquko ezenziwe ziyagcinwa.
