Kungani owasungula le isixhumi SCART, futhi yini izinzuzo zayo

Ngasekupheleni kwawo-80-yalolucwaningo ezweni lethu iphutha videorevolyutsiya. Ama-movie, izinhlelo umculo ngisho namabhayisikobho zocansi, aqoshiwe on tape kazibuthe, batheleka eSoviet Union. muva zokufinyelela usezivalile odakiwe emasekisini okubangela ithemba elingacacile lokuthi maduze sonke 'ayoba njengemifudlana emazweni aphesheya. " Kodwa iyisici yezenhlalakahle Kwakunenye uhlangothi - lobuchwepheshe.

Isiqophi, ividiyo ...

Okokuqala, bonke imishini kwakubiza kakhulu. Akekho simemezelo isimanga emaphephandabeni iziphakamiso ukushintsha indawo ezweni, noma ngisho nekamelo efulethini ngokuhlanganyela kwi athandwayo kudivayisi VHS uhlelo. Futhi uma umgcini-mibhalo uqobo kwaba nje into ebizayo, izindleko TV angaphandle ushaye zonke irekhodi ongazicabanga futhi ezingqubuzana ngokuqondile ingqondo. In the Eighties sekwephuzile, amaJapane multi-uhlelo umamukeli kungadla izinkulungwane eziningana "ugodo", naphezu kweqiniso lokuthi kubhekwa iholo ohloniphekile onguchwepheshe ruble, anamakhulu mathathu.

Indlela ukuxhuma ividiyo ku-TV yasekhaya

abanikazi Happy isimangaliso Japanese noma South Korean ngokushesha wafinyelela esiphethweni ukuthi TV yethu kungenziwa ngempela esetshenziswa ukubukela Uhlelo isiqophi angaphandle. amayunithi Iningi Soviet, isihambile ngesikhathi, wayevele wonke amadivaysi kudingeke ukuba uxhume okokusebenza kwevidiyo okungukuthi esakhelwe isiqophi semithombo PAL-SECAM futhi SCART isixhumi phezu kwesembozo sangemuva. RC nje zimenyezelwe nakubo futhi ithuba noma ngabe ukufaka bavimba okulula amapulangwe kudingekile, ukulawula amamojuli kanye photodetectors isignali infrared. Ngokushesha kwaba khona ukushoda izintambo elihambisana yokuxhuma, okuyinto ngokulangazela yakhiwa ngenxa yabaningi-co-operatives bese amabhizinisi angasese.

I Wiring elula

Wiring SCART isixhumi ayikanye nzima, ikakhulukazi ngoba ividiyo lokuqala amateur edingekayo imisebenzi eyisisekelo kunazo. Kulabo nje bafuna ukubukela izinhlelo aqoshiwe ngaphambilini, ulahlekile oxhumana ezintathu eziyinhloko: yesibili nelesithupha (phakathi kwawo kwaba ukubeka jumper) unesibopho umsindo, amabili - yevidiyo futhi Yiqiniso, okudingekayo emhlabathini (ipuleti, izungeza lonke isixhumi). Kuyefana nasendleleni labo abathenge ngayo isidlali - ". Nevidyo rekhoda ngokugcwele" kudivayisi ayibizi kuqhathaniswa Sebenzisa efanele ikhebula kwakuvikela nge 75-Ohm impedance imvamisa, kodwa umkhuba, unikezwa ubude esifushane, kulesi simo, abakhiqizi abaningi abondliwa, ikakhulukazi njengoba iningi izinga amateyipu ukuqoshwa kwesokunxele okuningi okufanele oyifunayo, kanye ukucaciseleka izakhiwo isithombe isixhumi ngaphakathi the ngcosana abathintekayo.

Ukuze unike amandla ama-apharathasi ngokuchofoza sangaphandle ongaphakeme imvamisa umthombo (omunye VCR noma i-TV) ku "audiomono" Imodi, inani ompompi edingekayo ukuze kabili ngokwengeza 1st, 3rd (umsindo) kanye imizuzu 19 (ividiyo) oxhumana.

Lezi eziwuhlupho 20 oxhumana nabo "umhlaba"

Njengomthetho, intambo uxhumano kwaba ikhebula ngakolunye uhlangothi lwale okwakuwuphawu isixhumi SCART, ngakolunye - amabili, amaqembu amane noma ayisithupha contact American ejwayelekile RCA (okuthiwa ifomu ezithile "tyulpanchikami"). Empeleni yayo, kwaba adaptha elula ivumela uxhumano kukagesi umthombo qapha isiqophi (TV). Abanikazi of isiqophi ngokuvamile ukufunga, ukuqalekisa ama-ebumbene ngenxa ukuntuleka kokuzibophezela kwenziwe izilinganiso jikelele, uma ucabangela ukuthi lo 21 pin idivayisi lelula - kungcono kakhulu.

TV kuphela abantu-Ochwepheshe, okuyiwona SCART isixhumi isikimu wayengeyena "izincwadi Chinese" bakwazi ukuba siqonde nesithembiso Indlela ingxenye French Union of electronics abakhiqizi, ngemva kwalokho-ke lethiwa (Syndicat Des Constructeurs D'Appareils, Radiorecepteurs Et Televiseurs - SCART).

Kungani kunjalo nzima? Futhi yingakho!

Ngokungafani ezivamile "tyulpanchikov», RCA-SCART isixhumi has eziningi eziwusizo, ukuhlinzeka Ukuphathwa amakhono olunzulu, umbala ukukhiqizwa kabusha kangcono, ngisho engacabangeki ekuqaleni '80s (futhi yasungulwa ngo-1983) kusakata ngetinombolo kubahlali.

Namuhla futhi kancane ifundiswe electronics abathengi bazi ukuthi ezihlukahlukene imibala esikrinini kudalwa zonke izingxenye ezintathu: obomvu, oluhlaza, futhi okwesibhakabhaka. Hlukanisa zinamanzi module umbala aqede eziningi kokuthikanyezwa, futhi nokuthungatha kwenza isithombe esicacile. Lokhu ikhono inikeza isixhumi SCART lapho 7-th, 11-th noxhumana nabo 15-th zisetshenziselwa ukuphakela isignali RGB, futhi kushintshana kubo ne 5th, 9 futhi 13 eyenzelwe ukuvikela amagobolondo.

Kodwa akugcini lapho zonke izici ukuthi ine SCART isixhumi. Pinout kudinga ikhono ukuze ujike ngokuzenzakalelayo futhi ukuvala TV ngesikhathi esifanayo nge ephansi imvamisa isignali umthombo (DVD noma VCR), kungakhathaliseki ukuthi iyiphi inkampani kukhiqizwa imishini. Ngokuzimela esitshalweni kanye esibanzi ekubonisweni mode.

Ngaphezu kwalezi imisebenzi, kukhona contact ezimbili digital - 12 th-14 th, presciently kuqokonyiswa onjiniyela French ngo-1983, lapho cishe bonke electronics yasendlini babe analog. Kukhona isixhumi ngenxa timer, kuba inombolo eziyishumi.

Ngakho, 20-pin kanye eyodwa jikelele (inani 21) - akuyona kangaka. Ukuze nokuzijabulisa kwesimanje Videocenter eside yabo ngokwanele Nokho ukunika amandla Dolby Kaka Akasekho ngokwanele ...
