Isihloko siqoqa amasignali emithonjeni eminingana, iwacubungule futhi iwasakaze kunethiwekhi yekhebula.
Okuqukethwe ochungechungeni lwezihloko
- Ingxenye 9: Isihloko
- Ingxenye 10: Ukuxazulula inkinga inethiwekhi ye-CATV
Sekuvele kunendatshana enhle ngoHabre mayelana nokuklanywa kwesihloko: . Ngeke ngilibhale kabusha ngamazwi ami futhi ngizovele ngincome ukuthi labo abanentshisekelo bazijwayeze ngayo. Incazelo yalokho okusesikhundleni sami ngeke ingathakazelisi kangako, ngoba asinazo izinhlobo ezihlukahlukene zemishini, futhi konke ukucutshungulwa kwesignali kuphathwa i-chassis ye-AppearTV enamakhadi ahlukahlukene okunweba, izinhlobonhlobo zazo ezivumela ukuthi konke ukusebenza kungene kukho. ama-chassis amayunithi amane amaningana.
Isithombe esivela kuwebhusayithi
Lawa madivayisi akuvumela ukuthi ulawule zonke izinqubo ngokusebenzisa isikhombimsebenzisi sewebhu esisebenzayo, esincike kokuqukethwe kwehadiwe ye-chassis.
Ngaphezu kwalokho, asiqoqi isignali esemoyeni, ngakho-ke okuthunyelwe kwethu kwe-antenna kubukeka kanjena:
Isithombe seforamu Angivunyelwe ukuthumela isithombe sangempela sesiteshi sethu.
Le nombolo yezitsha iyadingeka ukuthola iziteshi ezivela kumasathelayithi amaningana ngesikhathi esisodwa.
Isignali yesathelayithi ivamise ukuvalwa ngokukrwabha: lolu wuhlobo lokubethela lapho izimpawu zokulandelana zixutshwa ngokuya nge-algorithm ethile. Lokhu akudingi amandla amaningi ekhompyutha nesikhathi sokwenza, okusho ukuthi isignali icutshungulwa ngaphandle kokulibala. Ngefomu lehadiwe, isihlonzi sobhalisile (ngisho noma kungumhlinzeki odlulisela isignali kunethiwekhi yakhe) kuyikhadi elijwayelekile eline-chip, elishuthekwa kumojula yokufinyelela enemibandela (CAM) ene-interface ye-CI, efanayo kunoma iyiphi i-TV yesimanje.
Empeleni, zonke izibalo zenziwa ngaphakathi kwemojuli, futhi ikhadi liqukethe isethi yokhiye. Umsebenzisi angabhala ngemfihlo ukusakaza ngokhiye ikhadi elibaziyo (futhi u-opharetha ngokwakhe uzibhale ekhadini) futhi, ngaleyo ndlela, aphathe isethi yokubhaliselwe kuze kube yilapho enqamula ikhadi ngokuphelele ohlelweni, eshintsha isihlonzi “somqhubi” oyinhloko. Lena incazelo nje evamile yokuthi amasistimu okufinyelela anemibandela asebenza kanjani; empeleni, maningi ahlukene: ngakolunye uhlangothi, ahlala egetshengwa, kanti ngakolunye, ama-algorithms aba nzima kakhulu, kodwa lokho kuhluke ngokuphelele. indaba...
Njengoba u-opharetha ehlinzeka ngamaphakheji eziteshi ezikhokhelwayo kunethiwekhi yakhe, ngakho-ke kuyadingeka ukuthi uwafake ikhodi ngaphambi kokuwadlulisela kunethiwekhi. Lo msebenzi wenziwa imishini yomhlinzeki wesistimu yokufinyelela enemibandela yenkampani yangaphandle, ehlinzeka lokhu ku-opharetha njengesevisi. Izinto ezifakwe kusihloko ziqinisekisa ukusebenza kwesistimu yokufinyelela enemibandela kokuqukethwe: kokubili ukubethela nokulawula okhiye ababhaliswe kumakhadi ahlakaniphile.
I-PS Akekho owangisiza ngesihloko se-DOCSIS, uma kukhona onesifiso, ngizojabula, ngibhale.
