Po n\u011bkolika dotazech \u010dten\u00e1\u0159\u016f jsem p\u0159ipravil pohled do nitra tohoto p\u0159ij\u00edma\u010de dod\u00e1van\u00e9ho k p\u0159\u00edjmu UPC v \u010cesk\u00e9 republice. Pokud se boj\u00edte sv\u016fj p\u0159ij\u00edma\u010d otev\u0159\u00edt, nebo jste jej je\u0161t\u011b nevid\u011bli, tak nyn\u00ed m\u00e1te mo\u017enost si jej prohl\u00e9dnout zevnit\u0159.
\n<\/a>Cel\u00fd p\u0159ij\u00edma\u010d je um\u00edst\u011bn do sk\u0159\u00edn\u011b v \u010dern\u00e9m proveden\u00ed s otvorem pro Smart kartu na p\u0159edn\u00edm panelu. Na prvn\u00edm obr\u00e1zku je pohled na cel\u00fd p\u0159ij\u00edma\u010d s odebran\u00fdm krytem. Je zde patrn\u00e9 rozd\u011blen\u00ed p\u0159ij\u00edma\u010de na jednotliv\u00e9 funk\u010dn\u00ed celky, kter\u00e9 dohromady tvo\u0159\u00ed cel\u00e9 za\u0159\u00edzen\u00ed. N\u00e1sleduj\u00edc\u00ed obr\u00e1zky V\u00e1m p\u0159ibl\u00ed\u017e\u00ed funkci jednotliv\u00fdch \u010d\u00e1st\u00ed p\u0159ij\u00edma\u010de. <\/p>\n

<\/a>N\u00e1sleduj\u00edc\u00ed obr\u00e1zek zachycuje blok pro komunikaci se Smart kartou. \u00dakolem tohoto bloku je zabezpe\u010dit procesoru mo\u017enost z\u00e1pisu a \u010dten\u00ed na kartu. Nap\u0159\u00edklad pokud neplat\u00edte pravideln\u00e9 poplatky UPC, tak p\u0159ijde z dru\u017eice povel k zablokov\u00e1n\u00ed Va\u0161\u00ed karty a procesor vyma\u017ee p\u0159\u00edstupov\u00e1 data k programov\u00e9 nab\u00eddce. Naopak pokud \u0159\u00e1dn\u011b plat\u00edte, doch\u00e1z\u00ed k obnoven\u00ed informac\u00ed na kart\u011b o tom, do kdy m\u016f\u017eete dan\u00fd kan\u00e1l sledovat.<\/p>\n

<\/a>N\u00e1sleduje dal\u0161\u00ed modul tvo\u0159en\u00fd satelitn\u00edm tunerem a modul\u00e1torem. Tento funk\u010dn\u00ed blok m\u00e1 za \u00fakol p\u0159ipravit mezifrekven\u010dn\u00ed satelitn\u00ed sign\u00e1l v p\u00e1smu 700 – 2100 MHz pro procesor a analogov\u011b digit\u00e1ln\u00ed p\u0159evodn\u00edk. Procesor mu pouze p\u0159ed\u00e1 informaci o tom na jak\u00e9m kmito\u010dtu chce p\u0159ij\u00edmat a o zbytek se ji\u017e postar\u00e1 tuner. Blok modul\u00e1toru (pro ty co jej je\u0161t\u011b pou\u017e\u00edvaj\u00ed) m\u00e1 za \u00fakol p\u0159ev\u00e9st analogov\u00fd videosign\u00e1l na televizn\u00ed sign\u00e1l zpracovateln\u00fd klasick\u00fdm ant\u00e9nn\u00edm televizn\u00edm vstupem.<\/p>\n

<\/a>A dostali jsme se a\u017e ke sp\u00ednan\u00e9mu zdroji. tato \u010d\u00e1st p\u0159ij\u00edma\u010de je pouze k vytvo\u0159en\u00ed po\u017eadovan\u00fdch nap\u00e1jec\u00edch nap\u011bt\u00ed pro chod cel\u00e9ho p\u0159ij\u00edma\u010de. K pozastaven\u00ed je tu snad jen jejich po\u010det, j\u00e1 jestli dob\u0159e po\u010d\u00edt\u00e1m jsem na\u0161el t\u0159in\u00e1ct v\u00fdvod\u016f k procesorov\u00e9 desce, co\u017e mi i p\u0159i \u010dty\u0159ech nap\u00e1jec\u00edch nap\u011bt\u00edch a vyp\u00ednac\u00edmu vstupu zdroje p\u0159ipad\u00e1 p\u0159eci jen p\u0159esp\u0159\u00edli\u0161. Ale n\u011bjak\u00fd d\u016fvod k tomu jist\u011b konstrukt\u00e9\u0159i od Philipse m\u011bli. \ud83d\ude42<\/p>\n

<\/a>Jako posledn\u00ed \u010d\u00e1st jsem si nechal hlavn\u00ed procesorovou desku s p\u0159evodn\u00edky. Je to vlastn\u011b cel\u00fd mozek satelitn\u00edho p\u0159ij\u00edma\u010de. Tato deska m\u00e1 na starost p\u0159evod p\u0159ij\u00edman\u00e9ho sign\u00e1lu do digit\u00e1ln\u00ed podoby pro procesor, dek\u00f3dov\u00e1n\u00ed MPEG + Cryptoworks, p\u0159evod obrazu do analogov\u00e9ho videosign\u00e1lu v\u010detn\u011b vlo\u017een\u00ed grafick\u00e9ho ONSCREEN, ovl\u00e1d\u00e1n\u00ed lok\u00e1ln\u00edho display a celou \u0159adu dal\u0161\u00edch funkc\u00ed. Bohu\u017eel se mi je\u0161t\u011b nedostalo do ruky sch\u00e9ma a tak si mohu jen d\u011blat p\u0159edstavy o tom, co kter\u00fd obvod d\u011bl\u00e1, ale o tom a\u017e n\u011bkdy po dal\u0161\u00edm zkoum\u00e1n\u00ed.<\/p>\n\n\n
