Yintoni iadaptha yeCI kunye nemodyuli yecam yeTV

Imodyuli yeCI (imodyuli yeCI + CAM) yindawo ebekwe ngasemva kwesixhobo. Le nkqubo ivumela umsebenzisi ukuba abonelele ngofikelelo kumxholo ofihliweyo ngaphambili ohanjiswe nge
-TV yesathelayithi . Oku kufanelekileyo xa kukho amajelo angafumanekiyo, okanye kukho isiseko sedatha ofuna ukuvula ukufikelela kuso, umzekelo, iifilimu okanye oopopayi.

Esi sishunqulelo simele iModyuli yoFikelelo oluneMiqathango (imodyuli yofikelelo olunemiqathango yeci cam), ngelixa imodyuli yona ngokwayo ifakwe kwi-CI ekhethekileyo (ujongano oluqhelekileyo) slot.

Ingaba isebenza kanjani

Kucwangcisiwe ukubeka ikhadi elithile le- smart kwimodyuli ye-CAM
ukwenzela ukuguqulwa kwekhowudi elandelayo, ebonelelwa ngumboneleli we-satellite okanye wentambo ye-TV. Ngaphandle kweli khadi, imodyuli ayiyi kusebenza, ngenxa yokuba yonke idatha , ezifanelekileyo kuguqulelo oluntsonkothileyo zibekwe ngokuthe ngqo kwesi siqalelo. Ubukho beli khadi bumele ukufikelela kwizinto ezihlawulelwayo ezibonelelwa ngumboneleli wenkonzo.

Ngaba zonke iiTV zixhotyiswe ngemodyuli yekhamera

Njengomthetho, imodyuli yeCAM ifakwe ngokuthe ngqo kunye neseti yeTV. Kodwa kunokuqatshelwa ukuba ayizizo zonke iiTV ezixhotyiswe ngesi sixhobo. Kwimeko apho i-modular element ayifumaneki, kuya kufuneka ithengwe ngokwahlukileyo kwixesha elizayo. Kungenjalo, ababoneleli-nkonzo baya kuba nako ukubonelela ngesi sixhobo ngokuthe ngqo ngenkonzo ngokwayo. Nangona kunjalo, ihlala inikezelwa ngerenti ngemali encinci kakhulu.

Izinto ezilungileyo zokusebenzisa imodyuli yekhamera yeTV

Inzuzo ephambili kukuba xa kukho imodyuli yekhamera eyakhelwe-ngaphakathi, inani lezixhobo ezifunekayo zokusasaza umabonwakude lincinci. Emva koko awudingi bhokisi yokusetha-phezulu ukufumana
iTV yedijithali , kunye ne-tuner esetyenziselwa ukusasaza umabonakude wesathelayithi. Izibonelelo zikwabandakanya:

1. Ukunciphisa izixhobo ezisetyenzisiweyo, kuthathelwa ingqalelo into yokuba imodyuli ye-TV yekhamera ngokuthe ngqo ithatha indawo eninzi.
2. Akukho mfuneko yokuphuma eyongezelelweyo apho i-tuner okanye i-set-top box ixhunyiwe.
3. Ungasebenzisa ngokulula ipaneli yokulawula enye, awudingi eyesibini, njengoko kwenzeka xa usasaza umabonwakude ngebhokisi yokumisela.
4. Azikho ezinye iintambo ezisetyenziselwa ukubonelela ngosasazo.
5. Azikho ezinye iibhloko, ubukho obunokuthi buchaphazele kakhulu umgangatho womfanekiso kunye nesandi.
6. Akukho mfuneko yokukhupha imali eqinileyo yokuthengwa kwezixhobo ezongezelelweyo.
7. Seta nje kwaye uqhagamshele.

Kusebenza njani ukwenza iikhowudi?

Ukuhanjiswa komxholo kumabonwakude wedijithali kuqhutywa ngokuthe ngqo kwifom efihliweyo. Ukuvula lo mqondiso, uya kufuna ikhowudi eguqulwa ngumboneleli ngokuthe ngqo ngokwe-algorithm ingentla. Ukhutshelo lwenziwa kwi-decoding smart card, ekhutshwa ngumboneleli ngokuthe ngqo ekuthengeni inkonzo. Imijelo ehlawulwa ngokukodwa, kunye naleyo ibandakanyiweyo kwisicwangciso sentlawulo, iya kuvulwa kwixesha elizayo.
Amanye amajelo aya kuhlala evaliwe ngokuthe ngqo. Ukuvula, kufuneka unakekele iishuni ezizodwa. Le miqondiso ifunyenwe kwi-cable TV kumgangatho we-DVB-C / DVB-C2, ngelixa i-satellite –
DVB-S / DVB-S2 .

Indlela yokudibanisa imodyuli yekhamera kwiTV: ukufakela kunye noqwalaselo

Ngokuxhomekeke kwimodeli ethile, imodyuli yekhamera inokudityaniswa ngokuthe ngqo kwi-slot yeCI okanye nge-adapter eyahlukileyo enikezelwa ngokuthe ngqo kwiTV. Isixhobo semodyuli sifakwe ngasemva kweTV: Kowokuqala kwimeko, kuya kufuneka wenze oku kulandelayo:

1. Faka ikhadi elihlakaniphile elibonelela ngofikelelo olunemiqathango kwimodyuli.
2. Khangela ukuba ikhadi lifakwe ngokuchanekileyo na, ngakumbi, abafowunelwa bechip kufuneka baqondiswe ngokuthe ngqo kwicala langaphambili lalo mnqongo.
3. Eli khadi alithengwanga kunye neemodyuli, kufuneka lihlawulwe kwaye lifunyenwe kumnikezeli wenkonzo yeTV.

Ukufakela nge-adapter ye-CI

I-adaptha inikezelwa kunye nomabonakude. Ukuba into ilahlekile, ungayithenga kwiziko lenkonzo ekhethekileyo. Inkqubo yokuhlohla ijongeka ngolu hlobo:

1. Kwiphaneli yangasemva yeTV, kufuneka ususe isitikha kwindawo apho iadaptha ifakwe khona.
2. I-adapter ifakwe kunye nezinto zoqhagamshelwano kwimingxuma enikezelwe kule nto.
3. Ngokucinezela phantsi kwi-adapter, unokuxhuma ngokulula kwikhonkco.
4. Qinisekisa ukuba into idityaniswe ngokuqinileyo ngokwaneleyo kwaye, kwangaxeshanye, ayiyi kugxadazela.
5. Faka ikhadi lofikelelo kwimodyuli efanelekileyo.
6. Kuya kufuneka uqinisekise ukuba ikhadi lidityaniswe ngokuchanekileyo, ngokuqwalasela ukuqhelaniswa koqhagamshelwano lwentsimbi yekhadi.
7. Ikhadi ngokwalo lithengwa ngokwahlukileyo kumboneleli wale nkonzo, umboneleli.
8. Isiqalelo semodyuli enekhadi elifakiweyo liqhagamshelwe kwiadaptha esebenzayo.

Iindidi zeemodyuli zeCAM kunye nee-adapter zeCI

Ngokuxhomekeke kwinguqulelo yale adaptha, ikhadi elinye okanye amabini okufikelela anokuxhaswa. Oku kufanelekileyo kwimeko xa kukho umnqweno wokusebenzisana nomxholo ngokuthe ngqo kubaboneleli ababini. Ukongeza kwi-adapter yendabuko, unokufumana kwakhona ukuguqulwa ngophawu “+”. Olu phuhliso luhlaziywe ngokupheleleyo lwemveliso yenkqubo enokubonelela ngokhuseleko olupheleleyo kubutsotsi. Ezinye izinto ezongezelelweyo zomsebenzisi ziphunyeziwe, ezibandakanya:

1. Ukwalelwa ukurekhoda imveliso yesoftware.
2. Imvume yokujonga umxholo wemidiya kube kanye.
3. Ukuthintelwa kokubonelelwa kwemisebenzi yentengiso.

Iimodyuli ngokwazo zinokuba:

1. Yenzelwe inkqubo enye.
2. Uyilo oluguquguqukayo.

Izinto zemodyuli zenkqubo enye zinokusebenza kuphela ngegama elinye lokukhowudwa. Ziziswa kunye nekhadi elihlakaniphile xa kugqitywe isivumelwano. Izixhobo zendalo yonke zixhasa ii-algorithms ezahlukeneyo kunye neekhowudi. Emva koko ukufakwa kwekhadi lababoneleli abahlukeneyo kuyafumaneka. Ngexesha elifanayo, izixhobo zinquma ngokuzimeleyo ukuba yiyiphi i-decoding elandelelanayo eya kufaneleka kwimeko ethile. Xa umsebenzisi enemodyuli yendalo yonke, kuya kwanela nje ukufumana ikhadi kumnikezeli.

Imodyuli ye-ci cam elahlekileyo kunye nezinye iimpazamo – indlela yokusombulula iingxaki

Imodyuli yekhamera engekho

Kwanele ukujonga ukuba into yemenyu “I-interface eqhelekileyo” ikwimo esebenzayo. Oku kwenziwa ngale ndlela ilandelayo. Kwiimodeli ezichazwe kwi-F, H, J series (2013-2015), kuya kufuneka ufake imenyu ethi “Broadcast”, kwaye ngayo ukhethe into ethi “Common interface”. Kuthotho C, D, E (2010-2012), kuya kukwanela ukungena kwimenyu ebizwa ngokuba yi-“System”, kwaye emva koko uphume kwimenyu ye-“Common interface”. Ukuba le nto ayisebenzi, kuya kufuneka ukhuphe i-TV kwizinto eziphambili. Emva kokudibanisa kwakhona i-adapter kunye nemodeli. Nangona kunjalo, ukuba kukho ithuba elinjalo, kuya kufuneka uqhagamshele enye imodyuli ukwenza itshekhi.

Iitshaneli ezikhutshiweyo

Xa umsebenzi usebenza, kodwa amajelo awasayi kunqunyulwa, kuya kufuneka wenze inkqubo yohlengahlengiso olufanayo lwetshaneli. Ekugqibeleni, ukuba kuyimfuneko, kuya kufuneka uqhagamshelane neziko lenkonzo ukucacisa ulwazi oluchanekileyo.

Imodyuli ye-CAM yeTV ngaphandle komrhumo wenyanga – apho ungayifumana kunye nendlela yokuyimisa

Kule meko, kuya kufuneka uqhagamshelane nenkonzo ekhethekileyo eya kukunceda ufumane amakhadi ayimfuneko kwiTV yakho.

Okuhle nokubi

Kumabonakude anenkxaso kamabonakude wedijithali kwindawo ethile, kuya kufuneka uhlawule iimali ezongezelelweyo ezinomtsalane kwixesha elizayo. Kodwa ukongeza kwintlawulo eyongezelelweyo, kuya kufuneka uhlawule intlawulo eyongezelelweyo yemodyuli ngokwayo. Ngokukodwa, umrhumo uya kuhlala uthelekiswa ngqo neendleko zomamkeli opheleleyo. Xa usebenzisa i-cammodule, iiTV aziyi kukwazi ukubonelela kuphela ulwamkelo lwesignali yeTV, kodwa kunye neenkqubo zokurekhoda kunye neminye imixholo, ngaloo ndlela idala ugcino lwangoku lweenkqubo zeTV. Kwixesha elizayo, kucetywa ukuba kuhlaziywe inkqubo okanye kuyinqumame ukuze ijongwe ngaphandle kokuyeka.
