Yini okufanele ibe yindawo yanamuhla ye-Audiovideo Complex? Izici zobuchwepheshe zezakhi zemultimedia.
I-Planatron 2 Model Case eyenziwe ngengilazi ne-aluminium
Ama-cinema asekhaya avame ukuhlomela ama-TV ngezilinganiso zesikrini 16: 9
Qedela i-Theatre yasekhaya Zonke izinto ezikhethwe ngokucophelela ngokubambisana.
Imvamisa, amasistimu we-acoustic anesimo sokufana okungunxande ukunwetshwa ngokuqondile, kepha kwesinye isikhathi abaklami bamaphupho abanikeza amafomu angajwayelekile ngokuphelele.
Ikholomu eshumekiwe ngokuphelele
Yini okufanele ibe yindawo yanamuhla ye-Audiovideo Complex? Maye, akulula ukuphendula lo mbuzo, vele uvule umlomo wakho - futhi okusha okuzovela. Ama-Flat Plasma Panles nama-projektha wevidiyo, kanye namafomethi wevidiyo e-DVD, afika esikhundleni sokubuyisela ama-TV ajwayelekile nge-tube-kinescope yendabuko.
Ukuthuthuka okusha nemiqondo ethuthukisa ikhwalithi yomsindo nezithombe zivela cishe unyaka ngamunye. Khumbula ukuqala kwama-90s lapho izinkundla zokuqala zasekhaya zihlomele uhlelo lokudlala umsindo weDolby Pro Logic. Lowo kwakungumkhawulo wamaphupho wabathandi bomculo abafuna kakhulu. Namuhla, wonke la machibi asemnyakeni engu-10 edlule awaphelelwa yithemba.
Igama elithi "ithelevishini", elixakile ngokwanele, ekuqaleni kusukela ngekhulu leminyaka elidlule. Ngokokuqala ngqa ukwethula umqhathano sethu, usosayensi Konstantin Dmitrievoch ePeresky. Ukhulume ngombiko we-24AVGUST 1900G. EParis engqungqutheleni ye-electrotechnical yezwe lonke, enikezelwe ezinkingeni zokuhanjiswa kwezithombe kude ".
Ake sixoxe ngesimo sokuzijabulisa, ngenye indlela ebizwa ngokuthi isikhungo se-multimedia. Igama lesiNgisi igama le-multimedia lenziwa kusuka ku-latin multum - okuningi nabezindaba, ukugxila okuphakathi kwezinhlobo ezahlukahlukene zemidiya ye-elekthronikhi. Isikhungo seMultimedia siyaqondakala njengemidlalo yaseshashalazini yasekhaya ekwazi ukuxhumanisa amadivaysi ahlukahlukene okulalelwayo namavidiyo: ikhompyutha, ithelevishini ye-satellite, i-camcorder, njll. Yiziphi izinto, ngaphezu kwethiyetha yaseshashalazini yasekhaya, zizofakwa kule nkambiso, zinqunywa kuphela ngokuthandwayo ukunambitheka kwabanikazi. Kepha kunoma yikuphi, phakathi kwezinto eziphoqelekile "ze-Amazidingo" zesikhungo se-multimedia kuzoba nemithombo yesithombe nomsindo.
Ubona iso ...
Ake siqale ngemithombo yesithombe. Noma kamuva nje, kwakukhona amathelevishini ezinamazwi. Kepha namhlanje, ithelevishini i-monopoly kancane kancane inika isikhundla sayo, futhi amaphaneli we-plasma kanye nezinhlelo zokuqagela ziya ngokuya zisatshalaliswa. I-UNIC Eminye Izinzuzo: Ukuhlangane, ikhwalithi ephezulu yesithombe, amandla okuthola isithombe sosayizi omkhulu ngempela (kuze kufike kumamitha ambalwa we-diagonally). Ngasikhathi sinye, amasistimu wokuqagela acacile amaphaneli we-plasma akhange avela endaweni yokubuka intengo. Izindleko zamamodeli wakamuva awedluli ku- $ 7,000-24,000 edonsa wonke ama- $ 7,000-24,000.Ukuthola umsindo noma isithombe, idivaysi iyadingeka ukukhipha imininingwane evela kumphathi noma ether ukucubungula lolu lwazi, kanye nokudlala isithombe noma umculo ngendlela enobungane. Ubulukhuni ukuthi njengamanje kuluhlobo oluningi oluhlukile lwemithombo ye-audio nevidiyo, ngokwesibonelo:
- Ukuqoshwa kwe-analog komsindo kumapuleti namakhasethi ama-compact;
- Ukuqoshwa kwesithombe se-Analog kumathegi evidiyo (ama-VHS, S-VHS);
- I-FM Image Record kuma-laser disks (LD);
- Ukuqoshwa komsindo wedijithali (CD) kuma-CD;
- Irekhodi lesithombe sedijithali kanye ne-multichannel (inombolo yesiteshi - ngaphezulu kwemisindo emibili) kuma-DVD;
- Digital (DVD Audio, SACD) Qopha umsindo we-multichannel kuma-DVD.
Yini i-projektha yesimanje yevidiyo? Ake sithi: Nge-projektha yefilimu yasekhaya yesampula yama-70s, kuvamile, incane ngosayizi nobuningi (njengomthetho, kungabi ngaphezu kwe-5kg) nedivayisi yokusebenza esibulelekile. Kunezinhlobo ezintathu eziphambili zamaphrojekthi wevidiyo ahluke Ubuchwepheshe be-Imaphu Playerback: Lawa amadivaysi afakwe nge-elektroni beam tube (ama-cry projektha), kanye nama-phrojekthi we-LCD ne-DLP. Ukwakheka kwesithombe sangaphakathi, ukubola kwemibala eyinhloko (ebomvu, eluhlaza okotshani, okuluhlaza okwesibhakabhaka) kusetshenziselwa ukwakha isithombe. Kwenziwa ngezindlela zokubona. Ama-Projectors we-LCD ne-DLP ahlukile komunye nomunye ngesithombe sokulawulwa kombala. Amaphrojekthi we-VLCD alesi sisetshenziswa se-Liquid Crystal Matric ngokushintsha kube sobala kwezinto eziyi-microscopic (okubizwa ngokuthi yi-LCD Technology). ICineza VPL-HS1, i-Sony; I-PT-L701E, Panasonic; I-VT540, NEC.
Ngo-1955 ... inkinga yokwakha isikhungo esisodwa somculo (ukuze ungasebenzisi imali eyengeziwe yezimali ezibizayo) abakhiqizi bemishini yomsakazo bedidekile ngaphambi kweMpi Yezwe Yesibili. Imisakazo, amarekhodi wetheyipu yomsakazo kanye nama-magnutodioles, amadivayisi ahlanganisa umsakazo, rekhoda ye-tepi nomdlali avele ekukhanyeni.
Ku-DLP-Type Projectors (VPD-MX10, Sony; UGE S-Lite, Philips), umthombo wesithombe uyi-microcircuit ngedivayisi yokuhambisa micromirror (idivaysi ye-Digital Micromirror). Iqukethe cishe izibuko zensimbi ezincane, ezishintsha i-angle yokuthambekela ngaphansi kwesenzo sesiginali yokulawula. Ngenxa yalokhu, imisebe eboniswa izibuko ziwe (ngokusebenzisa i-Projection Lens) esikrinini, noma cha, ukudala isithombe. I-HalfTone itholakala ngokubamba isibuko esikhundleni esifanayo phakathi nesikhathi esibaliwe sesikhathi. Amamodeli ahlukanisiwe asebenzisa i-matrix eyodwa ye-DMD nesihlungi esikhanyayo. I-Canon Ethuthuke kakhulu (i-LV-7105, iCanon; I-LP530, i-Infocus) - Sekuvele imilobane emithathu enezibuko zokuhlunga, ngokwahlukana ngombala ngamunye oyinhloko. Izindleko zamadivayisi lapho kusetshenziswa khona ubuchwepheshe be-DLP kuphakeme kunalokho okuseleyo, nokho, ikhwalithi yesithombe esiphumela. Ngakho-ke, ama-DLP ama-projektha (aqhathaniswa namaqoqo awo we-LCD) ahlinzeke ngokuhamba okukhanyayo okukhanyayo futhi adlulisele kangcono izigcawu ezinamandla ngokushintsha imininingwane eshintsha ngokushesha.
Ekugcineni, inani eliphakeme lobuchwepheshe be-Projection (izimpesheni zokubuka kwekhwalithi yesithombe) zibhekwa njengemodeli esebenzisa amashubhu amathathu e-elektroni anokukhanya ngokukhanya okukhulayo kokukhanya. Ngokusho komklamo, la mashubhu ahluka kancane kusuka ku-Kinescops ezijwayelekile ezimnyama namhlophe, ngaphandle kwengilazi enkulu kanye nokukhanya okuphezulu kakhulu. Isibhedlela, ama-Projectors anamadivayisi we-CRT abiza kakhulu (amanani abo asuka ku- $ 15,000 kuya ku- $ 100,000). Ngaphezu kwalokho, amashubhu we-elektroni aRay adinga ukushintshwa ngezikhathi ezithile (iqoqo elisha lamashubhu azobiza amadola ayizinkulungwane eziningana) kanye nokulungiswa kobungcweti, zombili ngemuva kokufaka i-projektha endaweni futhi njengokukhanya kwe-flux ekhanyayo kwehla. Kodwa-ke, wonke amaphutha anxephezelwa yikhwalithi yezithombe eziphumayo, ziphelelwe ngumncintiswano.
Ingxenye eyinhloko yanoma iyiphi i-TV ibhekwa njenge-kinescope (i-electron beam tube), i-B1998 enelungelo lobunikazi. EMelika, unjiniyela waseRussia uVladimir Kuzmich zvirkyn njengengxenye ye- "Television" ye-elekhtronikhi ".
Ama-video aklanywa ama-video ayakwazi ukudala isithombe sosayizi abakhulu kakhulu, nge-diagonal efinyelela ku-4-5 m. Kepha, maye, ikhwalithi enkulu yesithombe, imbi kakhulu (ikakhulukazi ngenxa yokwehla kokukhanya). Imvamisa abakhiqizi be-Projector bakhombisa ubukhulu bezithombe eziphezulu futhi ezinconyiwe zale modeli. Uma uzosebenzisa izinto eziphakeme kakhulu, nakekela umnyama ogcwele we-cinema - noma yikuphi ukukhanya kwangaphandle kuzokwenza isithombe se-fad. Ama-projectors e-CRT azwela kakhulu izingqimba ezikhanyayo, ngoba zivame ukukwazi ukuhlinzeka ngokusakazwa okukhanyayo okuncane kakhulu kunamadivayisi we-LCD ne-DLP. Izinhlobo ezimbili zokugcina zama-projektha zingasetshenziswa emakamelweni amnyama ngokwengxenye, kepha ama-CRT aprojekthi adinga ubumnyama obuphelele.
Ngakho-ke, esinye sezici ezibaluleke kakhulu ze-video projekli zingabhekwa njengokukhanya kwenani eliphakeme lokukhanya okubonakalayo okukhishwe yiwo. Enye inkomba efanelekile kwipharamitha isisombululo, esiyisiko ukuhlola inani lamaphoyinti (amaphikseli), aqondwe ngokwehlukile esikrinini esivundlile ne mpo. Ukulungiswa kokuqoshwa kwamavidiyo ku-DVD kungu-720576Pixels, kudingeka imvume eningi kuphela ukubuka izithombe zezithombe ezinziwe ngedijithali.
Amathelevishini aqagele asathandwa (abhale esihlokweni esithi "Amabhayisikobho, lapho ahleli khona kuma-slipper").

Isikrini esikhulu sakhe
Ngaphandle kwazo zonke izinzuzo zama-video projekli, amathelevishini (kokubili okwejwayelekile nokuqagelwa) ziyaqhubeka nokujabulela ukufunwa okuqinile njengengxenye yesikhungo se-multimedia sasekhaya. Ukuthenga i-Video Projector kunengqondo kuphela kulezi zimo ezilandelayo: a) Uma kufanele kusetshenziswe kuphela njengengxenye yaseshashalazini yasekhaya; b) Uma kunesikhafu esanele (ubuncane be-20-25, kodwa mhlawumbe ngaphezulu kwe-30m2) nehholo elibucayi. Isikhungo seMultimedia esifakwe i-TV sifunwa kancane kwemvelo ezungezile futhi singase sisetshenziselwe ukubukwa kwethelevishini yansuku zonke. Ngamanye amagama, uma unegumbi lemitha engu-14-18, alisetshenziswa hhayi njenge-cinema kuphela, njengoba umthombo wesithombe amukelekile impela i-TV. Namuhla, amasethi wezemidlalo yasekhaya, ehlanganisa ama-TV ngesikrini 25-29, "nikeza abakhiqizi abaningi: Samsung, JVC, LG. Lawa masethi ahlanganiswe nesidlali se-DVD, i-Hi-Fi video Recorder, i-AV Receiver kanye nesethi yama-acoustics, kwesinye isikhathi kufaka i-TV. Konke lokhu, njengomthetho, kufanelekile isethi ebishibhile ephelele yemishini egcwele izobiza umthengi ngo- $ 1500-3000.Njengamanje, njengamanje i-TV Vertigars ethandwa kakhulu nge-diagonal yesikrini 29 "iyathandwa kakhulu. Zishibhile kakhulu kunabalingani bawo abakhulu futhi ngasikhathi sinye aziphansi kwekhwalithi yesithombe kanye nezinga lokuphelela kwezobuchwepheshe. Ngaphezu kwalokho Ukuhlola amasayizi, izinzuzo zobuchwepheshe ezibalulekile ze-TV enhle zingabangelwa yi-100- ukuskena okumnene kwesithombe, esinyamalala iso elicasulayo lokuvuselelwa kwesikrini. Ngaphezu kwalokho, uma uzosebenzisa i-TV njengengxenye Isikhungo sevidiyo yasekhaya, kuyinto efiselekayo ukuthi ibe nzima, ngezilinganiso eziyi-16: 9, kuyadingeka ukubuka okuphelele kwama-movie.
Ngokuxhumana okujwayelekile kwemithombo eminingi "yemithombo", i-TV kufanele ifakwe nge-SCART, S-Video, izixhumi ze-RCA (kuzoxoxwa ngazo ngezansi). Yebo, hhayi okungenani umsebenzisi kubalulekile ukuze kube lula ukuphathwa i-TV. Kuyaziwa, imisebenzi enjalo yesevisi ifanelekile ngokuthi "isithombe esithombeni" (KV-28FD1, Sony; TX-32WS100T, ukulungiswa okuzenzakalelayo kwesilinganiso sevolumu kusiza ukuqeda izikrini zokukhangisa ezibandayo (CF-21F89, LG). Ngingathanda futhi ukuqaphela ukuthuthukiswa kwezinhlelo ezimbili ezihlanganisa i-TV kanye ne-DVD Player. Lokhu kufana kokuthandwa okuthandwayo okuthandwayo kubenikeza abathengi grundig (imodeli yeLenardo 92Flat). Ukuhlanganisa isidlali se-DVD kanye ne-TV kwesinye isikhathi kunikeza izindleko ezibonakalayo zokonga futhi kunikeza isibonakaliso esezingeni eliphakeme (izixhumi ezimbalwa, izindleko zokuxhuma ikhebula, imiphumela ephumayo kwisiginali yevidiyo).

Ikhompyutha
Amakhompyutha akho ezizukulwaneni zokugcina athembisa kakhulu imithombo ye-multimedia. Le nsizakalo ingathola umsindo nesithombe sekhwalithi ye-DVD, ukusindisa kakhulu izindlela. Ukuqhathanisa: Izindleko zeyunithi yesistimu yekhompyutha ezikwazi ukudlala ividiyo ku-DVD Standards Level ingama- $ 500-600. Abakhiqizi abaphambili bezinsizakalo zomsindo nezamavidiyo bakhiqiza i-gamut yemikhiqizo engabizi engaguqula ikhompyutha yakho ibe uhlelo lwe-DVD ngomsindo wedijithali wesiteshi eziyisithupha. Isibonelo, isidlali se-Video Logic DVD (kusuka ku-visidelogical), okuyiprosesa le-audiovideo ebhodini lekhompyutha, libiza ama- $ 95. Ividiyo yokuphuma ingaboniswa ku-TV, iphaneli ye-plasma noma i-projektha, ngaleyo ndlela ijike ikhompyutha ibe "ekhaya le-multimedia Center".Ngokuvela ekugcineni kwama-60s. Iteyipu kazibuthe evumayo (ubukhulu bokuhleleka kwe-13 mk) inkinga yenzekile, le tepi imnene kakhulu kangangokuba bekuvele kungenzeki ukugcwalisa kabusha ngengozi. Bekumele ngize ngecala elikhethekile lekhasethi, okwavela ntofontofo ekusingatheni lokho ekuqaleni kwama-90s. Amarekhodi we-Cassette Tape asuswe ngokuphelele ama-tape ama-coopers ama-coils.
Futhi akudingekile ukukhohlwa ngesizukulwane esincane, esidale imidlalo yama-computer (lokhu kusebenza nakubanikazi be-Sony Play Station Game Prefix). Ngokuxhuma ikhompyutha noma ikhonsoli yomdlalo kwi-projektha yevidiyo futhi usebenzisa i-Home Theatre Acoustics, ungafinyelela ngokuphelele, kuze kube nemininingwane emincane kakhulu, ukuphinda kabusha okuhlukile efulethini. Ubunzima bemizwa buqinisekisiwe!
Kungani ikhompiyutha yomuntu siqu ingavamile ukuhlanganisa nge-cinema yasekhaya kwi-multimedia tata? Isizathu ukuthi kunzima ngokwezobuchwepheshe ukuphatha ikhompyutha, ukubheka kalula ama-DVD ku-DVD Player, kanye ne-CD Player CDS. I-wizard ayisebenzi "Inkinobho yenkinobho eyodwa": ifake ikhasethi noma idiski, icindezele inkinobho futhi uthole umphumela. Ulwazi ngohlelo lokusebenza lwe-PC (imvamisa) kanye nekhono lokusebenza ngezinhlelo ezikhethekile. Ngakho-ke, ikhompyutha njengengxenye yohlelo lwe-multimedia yasekhaya inganconywa kuphela kubantu, kahle kuyo ukudiliza.
Ake sithi ungumnikazi ojabulisayo wengobo yomlando yevidiyo yasekhaya. Ikhompyutha izokusiza ukuletha ngoku-oda: Ukubuyisa amarekhodi, ukususa izingcezu ezingeziwe zazo; "Ngokweqiniso" ukuhlanza isithombe; Lungisa ukugqama nephalethi yombala; Sekela amarekhodi nabafundisi abahle kanye nethrekhi yomsindo efanelekile. Ukufeza zonke lezi zinqubo, uzodinga ikhompyutha nge-Pentiemiii processor nekhadi levidiyo elisekela okokufaka / ukuphuma kwesiginali yevidiyo (kumele ifakwe ama-videoin / videot sockets). Ngaphezu kwalokho, kufanele ufake uhlelo olukhethekile lohlelo lokucubungula ividiyo ekhompyutheni, njenge-Adobe Premiere Premio Studio. Maye, imvamisa uhlelo olunjalo lubiza kakhulu kunekhompyutha uqobo, i-premiere ephelele izobiza umthengi ngenani elingama- $ 700.
Hlanganisa futhi unqobe!
Ukuqoqa zonke izingxenye zohlelo lwe-multimedia oluphelele oluphelele, kudingeka isethi eqinile yezintambo. Ukusuka kwikhwalithi yentambo yokuxhuma ikakhulukazi kuncike ikhwalithi ephelele yomsindo nezithombe, ngakho-ke akunangqondo ukonga "kwi-wiring". Ngokusho kwama-connoisseurs, izindleko zekhebula lokuhlinzekwa zisukela ku-5 kuye ku-15% wezindleko zohlelo lonke.
Ikhebula lakhiwa kusuka ezintweni ezine eziyinhloko: umqhubi wesiginali; dielectric, i-infaulang conductor; ukuvikela okuvikela umqhubi emithonjeni yangaphandle yemisebe ye-electromagnetic; Futhi izixhumi zihlinzeka ngokuxhumana okuthembekile phakathi kwekhebula kanye nebhlokhi yohlelo oluxhunyiwe. Abakhiqizi bezintambo zokuxhuma zemikhiqizo e-elite (efana nekhebula le-Eagle, ikhebula le-monster, i-Persuthold) ekwenziweni kwemikhiqizo yalo basebenzisa ithusi le-99.9997%!). Zonke izinto nokuxhumeka kucutshungulwa ubuchwepheshe banamuhla kakhulu futhi kuyahambisana ngokucophelela namapharamitha. Akumangazi ukuthi izindleko zekhebula elinjalo zibalwa ngamashumi, noma amadola angamakhulu. Ngakho-ke, ukuthatha ikhebula, kufanelekile ukukhumbula igama elithi "ukufa amahlandla ayisikhombisa - futhi." Kulungile ukuthenga ikhebula lokuxhuma, ukulicabanga ngokucacile ngokwakho, lapho zonke izingxenye zohlelo lwemultimedia zizotholakala khona, amamitha angeziwe ngeke aguqule izindleko ezengeziwe, kepha kungenzeka ukuthi azokwehlisa ikhwalithi yale threnti Isiginali.
Qaphela: Intambo yomsindo kulula ukuyilimaza! Unezintambo zokuzithoba egumbini, ungazibeki ngaphansi kombhoxo wena nemindeni yakho. Kuhle ukumongatha ukubekwa kwentambo ezindongeni, ngesimo se-wiring evaliwe. Ngasikhathi sinye, ungakhohlwa ukuthi i-wiring yenethiwekhi ingakunxenxa ukuphazamiseka ku-cable, yavalwa kakhulu - ngcela uhlenze okungenani i-20cm kusuka komunye nomunye.
Ukuphuma kuhlale kukhona
Emibhadweni yokukhangisa ehlobene nemishini yevidiyo, ihlangana kaningi "Ukufakwa kwezakhi", "okokufaka okuhlanganisiwe", "Skart" (scart), "i-S-Video-Input", "i-RGB-Input". Ungakuthola kanjani "okumnandi ngazo zonke izindlela" ngalokhu kuchichima kokungena?Hhayi ikhebula kuphela elixhuma amadivaysi ahlukahlukene (ngokwesibonelo, isidlali se-DVD kanye ne-TV) kubalulekile ukuqinisekisa ukuhanjiswa kwevidiyo okuphezulu kwesiginali yevidiyo (isibonelo, isidlali se-DVD ne-TV), kodwa futhi nendlela yokufaka ikhodi uqobo lwashintshwa. Iqiniso ngukuthi ezifundweni zethelevishini isithombe sidlula uchungechunge oluyinkimbinkimbi kakhulu lwezinguquko. Kukhethwe njengesiginali ye-RGB-HV (amasiginali amathathu abomvu anemibala, eluhlaza, eluhlaza okwesibhakabhaka nokuvumayo), bese kuguqulwa ku-sonal ebizwa ngokuthi yi-Enternent Signal, yona, - ividiyo ehlukile) ngezakhi ezihlukile zokukhanya neChroma. I-Inconto, kusuka ku-S-Video ithola isinali eyinhlanganisela lapho izingxenye zokukhanya kanye ne-chromatity zihlangene. Isiginali eyinhlanganisela iguqulwa ibe yimvamisa yomsakazo futhi ngenxa yalokho ngenxa yesiginali egcwele ether.
I-Transformation TV eqinisweni, ngokuhleleka okuhlelekile: Isinali ye-ETHER siphenduka ibe yinhlanganisela, bese ku-S-video, isakhi futhi, ekugcineni, singena kwi-tube yemisebe ye-RGB-HV. Ngokwemvelo, kuzo zonke izigaba, ukulahlekelwa okuthile kwekhwalithi yesithombe kungenzeka, ngakho-ke, ngokweqiniso, kungcono ukurekhoda nokukhiqiza kabusha ngaphandle kokuguqulwa amasiginali RGB-HV.
Kungani kudingeka uguqule isinali ye-RGB-HV kwingxenye, ngaleyo ndlela kukhulisa isithombe? Kuvela ukuthi isibonakaliso sefomethi ye-RGB-HV asikwazi ukubona ama-TV amnyama namhlophe, okukhona emhlabeni kwakukhona iningi lapho izindinganiso zokusebenzisa ngocingo zivunywa. Ngaphezu kwalokho, isibonakaliso se-RGB-HV sasihlala "strip" ebanzi kakhulu emoyeni - bekufanele sinqume cishe amahlandla amathathu inani leziteshi ze-TV. Yebo, nomehluko phakathi kwe-RGB-HV ne- "Ingxenye" isithombe siyabonakala kuphela ngemishini esezingeni eliphakeme.
Isibhedlela, amasiginali wokushintshana ngezinga le-RGB-HV ayakwazi hhayi yonke impahla yasendlini. Ngaphezu kwamakhompyutha angeniswe kumqapha, isiginali enjalo, mhlawumbe, mhlawumbe, ama-video ama-video. Amadiski e-CDD lapho enza ukuqoshwa kokuqoshwa, kusetshenziswa isibonakaliso sengxenye, ngakho-ke abadlali be-DVD abahamba phambili baxhuma ekufakweni kwengxenye. Kodwa-ke, ithelevishini nayo ivame ukungabikho. Amamodeli we-TV angabizi anokufaka kuphela kwesiginali eyinhlanganisela, i-ALO, ikhwalithi ephansi kakhulu yakho konke okungenzeka. Isiginali ye-SATIM futhi isebenza amarekhodi wevidiyo e-VHS. Kepha njengoba amarekhodi e-VCR ngokwawo anekhwalithi ephansi, kulokhu ukusetshenziswa kwesiginali eyinhlanganisela kufanelekile. I-Avot Xhuma isidlali se-DVD ngaphezulu kokufaka okuhlanganisiwe (imvamisa ifakwe ukuxhumana kwe-RCA noma i-Scart) akusizi ngalutho kwi-TV, isithombe sizoba seMediocre.
Ama-TV asezingeni eliphakathi kakhulu aphakathi nendawo afakwe okokufaka kwesiginali ye-S-video, okuphelelwa yisikhathi kancane njengesiginali yengxenye. Ukuba khona kwe-S-Video Ukufaka isikhathi sokufaka isidingo esincane sokulungiselela sedivayisi esiveza isithombe ngohlelo lwemultimedia noma yaseshashalazini yasekhaya.
Kudalwe ekuqaleni kweminyaka yo-1930. Isidlali sikagesi esingaphezu kweminyaka engama-50 sasala umthombo ophambili womsindo ekufakweni kwe-elite acoustic ye-hi-fi ne-hi-ukuphela. Ama-Dest-end Decks wokudlala ama-Vinyl Disc ("Turntables") ukuqondiswa kwemikhawulo kusatholakala.
Imibandela ye-RCA ne-SCART ikhombisa uhlobo lwesixhumi esisetshenziswa kukhebula. I-RCA, noma i-AV (Audio / Video), ebanzi, ebizwa nge- "Tulip", ingenye yezinhlobo ezivame kakhulu kwezixhumi. "I-SCART" noma "I-comb" ibizwa nge-plug yamashumi amabili anqamula avele ku-Video Engineering muva nje. Ekuqaleni, i-scart yakhulelwa njenge- "switch" yendawo yonke, lapho ungadlulisela khona nanoma yisiphi isiginali, umsindo, imiyalo yokulawula. Umoya wokungenisa izihambi, neminye imisebenzi enjalo, ikhwalithi yekhwalithi yahlupheka ngokungafanele, isethi ayisabazitha kakhulu abavinjelwe. Kuze kube kuzo zonke ezinye izimo ezilinganayo, isixhumi se-Scart siholela ekuhlanekezelweni okukhulu kwesiginali.
Yiziphi iziphetho ezizibuza ngenxa yalokho? Uma ufuna ukusebenzisa i-TV noma iphaneli ye-plasma njengomthombo wesithombe ohlelweni lwe-multimedia yasekhaya, qiniseka ukuthi banengxenye kanye / noma okokufaka kwevidiyo (kulokhu kwanele ukubheka iphaneli, lapho AmaJacks ezixhunyiwe okokufaka okuhlukile ahlukaniswa kalula). Ngaphezu kwalokho, kuyinto efiselekayo ukuthi izixhumi zokuxhuma imithombo yevidiyo zenziwa ngendlela yama-plugs ahlukene, futhi hhayi obomvu oqinile.
Ama-70s. - Peak of the Heyday of the reco Record Record. Kuyathakazelisa ukuthi ikhwalithi yesiginali yomsindo etholwe kulawa madivaysi ngenxa yejubane eliphezulu le-tape ezokuhamba kwamakhasethi asaqhubeka namarekhodi we-cassette angenakuqhathaniswa.
Hhayi nje izikhulumi
Ngonyaka owedlule, ukugibela ukuphelela kwakubhekwa njengeDolby Digital5.1 uhlelo lokukhiqiza kabusha lomsindo, olungasebenzisi ezimbili (njengasezinhlathini ze-stereo), kanye nambili amakholomu ayisihlanu kanye ne-subwoofer. Kepha namhlanje, "okujwayelekile kwekhwalithi ephezulu" sekuvele kungumsindo wedijithali ayisikhombisa, okwenziwe, ngokwemvelo, ngosizo lwamakholomu ayisikhombisa (ifomethi7.1). Uhlelo olusha luqukethe amakholomu angaphambili, ama-satellite aphakathi nendawo, ama-satellite amabili, angemuva kanye ne-satellite engemuva (kanye ne-subwoofer, njengasesistimu yekholamu engu-5). Ingabe sikhona isidingo sokusebenzisa inani lama-acoustics anjalo? Kuvela yebo. Ososayensi bathole ukuthi umuntu uphendula ngobuqili kakhulu imisindo ayiphonsa ngemuva kwakhe. Umbono wokuziphendukela kwemvelo uyaqondakala impela, izindlebe, futhi hhayi amehlo abhekene nalo ukuze aqinisekise ukuphepha ngemuva. Okwamanje, bonke abakhiqizi be-acoustics ngezinga elikhulu noma elincane abazinaka izikhulumi ezingemuva, cishe zazihlala zisezingeni eliphansi ngaphansi komphakathi "wazo."
Manje i-acoustic ingemuva "lilinganiswe ngamalungelo" nabakhiqizi bangaphambili baye baphendula ezifundweni zososayensi ngokushesha okukhulu. Ngaso leso sikhathi, amafomethi wokuhambisa wedijithali aneziteshi ezimbili athuthukiswa ngasikhathi sinye: I-digitalEx eyodwa evela kwaLolby Labs, amanye ama-DTS asuka ezinhlakeni zemidlalo yaseshashalazini. Zombili lezi zinhlaka zithuthukisa ukuhanjiswa komsindo ozungezile. Kuliqiniso, amafilimu alotshwe kunguqulo yedijithali eyisikhombisa asencane kakhulu futhi ayikho ngaphezu kweshumi nambili.
Kodwa-ke, kuhle, njengoba besho, kufanele futhi kube ngokulingana. Inani elikhulu lamakholomu egumbini lamamitha ayi-14-18 lizoholela ekuhlanganeni kwemithombo enomsindo, ukugcwala okugcwele kanye nokuhlanekezela amasiginali. Ungahlola ngokweqiniso ikhwalithi yefomethi 7.1. Ungakwazi kuphela ngaphakathi kwe-40m2.
Kukholakala ukuthi, ngokungafani, ake sithi, abadlali beDVD, amasistimu e-acoustic asevele efinyelele kuzinga lokuphelela. Ngalo mqondo, lezi yi- "Grande" yama-acoustics, ezinjengezinkampani zesiNgisi ziqapha umsindo, amandla acoustic, bw, atc, i-elac heco, kudala ukukhiqiza izinhlelo eziphakeme kakhulu ze-acoustic.
Khetha okuhle kakhulu komsebenzi omuhle kakhulu ongabongi. Indlela kuphela enokwenzeka isixazululo sayo ukulalela ama-acoustics owuthandile ngokukhethekile kuleli gumbi-salon. Ama-acoustic amasistimu amaningi angomakhelwane aphansi, asho kahle ithiyetha yaseshashalazini yasekhaya evezwa kahle, kepha amakona angathandeki ngomculo "ohlanzekile". Izikhulumi ze-Universal, kunjalo, kungenzeka ukuthi ukhethe, kepha intengo izoba phezulu futhi ingafinyelela itende lamakhulu amadola. Cabanga, ingabe uyawadinga ngempela ama-acoustics esifundo se-hi-end sokulalela umculo we- "ophilayo" we-symphonic, uma ulalela umculo onjalo kungakapheli kanye ngonyaka othanda kuye? Thola izidingo ezibaluleke kakhulu ezizohanjiswa kwizikhulumi. Kungcono ukubamba i-DVD ukulalela i-salon ngerekhodi elaziwayo, osuvele likwazile "ukushayela" kwimishini ephezulu.
