Satellite channel cov cim tsim los tiv thaiv kev xa rov qab, theej tawm lossis saib tsis raug cai, nrog rau kev tiv thaiv kev saib tsis tau tso cai ntawm cov neeg saib. Txhawm rau tiv thaiv piracy hauv lub tshav pob ntawm TV TV, lawv los nrog ntau dua thiab ntau qhov kev cai coding uas nyuaj rau kev nrib pleb. Tab sis, dhau sijhawm, qhov kev hloov kho tshiab tshaj plaws yog yooj yim tawg los ntawm hackers thiab pirates.
Viaccess encoding tshuab
Viaccess 2.3 yog tam sim no hacked tus txheej txheem tseem ceeb. Nws tau tsim los ntawm Fabkis lub tuam txhab Fabkis Télécom los tshaj tawm cov tshooj raws ntawm kev them nyiaj. Tom qab nyiag nkas, nws tau zoo dua los ntawm kev ua kom pom ib qho cim ntxiv TPS-Crypt teeb liab ntawm lub cev ntawm tus yuam sij. Siv cov txheej txheem encryption no, cov neeg tsim tawm tuaj yeem xa tawm ntau lub teeb liab ntawm ib zaug ntawm tib lub zaus. Tom qab ntawd, tus neeg tau txais xov tooj cua zoo li tsis tuaj yeem paub txog cov yuam sij, txawm tias nws tau nruab nrog emulator. Txhawm rau saib cov channels encryption nrog Viaccess 2.3 coding, cov neeg rau npe yuav tsum yuav AEC-hom yuam sij los ntawm tus neeg xa xov tooj satellite.
Viaccess 2.4, 2.5, 2.6 - peb hacked thiab tam sim no tsis muaj txiaj ntsig encodings, tab sis qee qhov kev ua haujlwm nyob rau hauv qhov encoding mus txog rau hnub no, piv txwv li, Mezzo classical music channel los ntawm Hotbird 13E satellite.
Viaccess 3.0, 3.1 yog qhov tsim kho xyoo 2007. Nyob rau lub sijhawm lawv tsis raug hacked, tabsis cov channels uas ua haujlwm hauv lawv tuaj yeem saib tsis raug cai, siv kart sib qhia.
Viaccess 4.0, 5.0 - tsim nyob rau xyoo 2012, nquag siv los ntawm cov neeg xa xov liaison los ntawm Fabkis, nrog rau tus neeg xa xov tooj ntawm Lavxias teb sab NTV-Ntxiv. Tsis hacked, tab sis them nyiaj raws tau yooj yim saib tsis raug cai los ntawm cartsharing.
Nagravision 2 coding system
Nagravision 2 tau siv dav dav los ntawm cov neeg xa xov tooj xaib hauv Tebchaws Europe. Nws tau qee qhov hacked, tab sis txhua qhov tsis muaj peev xwm raug tshem tawm los ntawm kev hloov kho cov kev hloov kho tshiab thiab hloov daim npav tseem ceeb rau ntau dua 4 lab cov neeg rau npe. Lub teb chaws Yelemees tau raug kev txom nyem tshaj plaws vim muaj daim npav pauv.
Yog hais tias lub Nagvision 2 encoding yog tawg dua, German kev khiav lag luam satellite yuav tau hloov 17 lab ntau daim npav, uas yuav nkag rau cov teeb meem kev poob peev nyiaj txiag.
Videoguard thiab Irdeto 2 encoding tshuab
Lub Videoguard thiab Irdeto 2 encoding tshuab yog cov muaj kev tiv thaiv tiv thaiv kev paub zoo tshaj plaws. Lawv siv los ntawm ib tug xov tooj ntawm lub satellite TV muab kev pabcuam hauv Tebchaws Europe, Russia thiab Ukraine. Txawm hais tias lub kaw lus yuam sij tsis tau muaj kev cuam tshuam thiab ua rau cov pej xeem muaj kev ywj pheej dawb, cov kab raws tau nkag ntawm Videoguard thiab Irdeto 2 cov tshuab tau yooj yim tuaj yeem saib tsis raug cai los ntawm cartsharing.
Videoguard coding system yog siv los ntawm Ukrainian satellite TV tus kws kho mob Viasat, thiab Irdeto 2 system yog siv los ntawm Lavxias teb sab neeg teb xov tooj Raduga TV.
BISS qhov system coding
BISS encoding system yog qhov yooj yim tshaj plaws thiab muaj qhov cuam tshuam rau kev nyiag nkas. BISS yuam sij tau yooj yim sib piv los ntawm kev xam cov qauv, txij li lawv tau muab zais hauv cov lus tshaj tawm hexadecimal. Tsis tas li ntawd, qhov teeb meem tseem ceeb ntawm lub system yog cov channel tso cai ncaj qha rau hauv lub satellite ntawv txais. Yog tias tus neeg tau txais lub pob hluav taws xob nrog qhov tseem ceeb emulator, nws yuav tsis nyuaj rau tawg BISS encoding rau nws.
