I-DTS Multi-Dimensional Audio ikhonjelwe ... Ngempela
Izinkampani eziningana ziphikisana nomqondo wezinhlelo ezizungezile-zomsindo ezingaphezu kuka-7.1 iziteshi zomsindo, okunye okubizwa ngokuthi umsindo omsindo. Kungenzeka ukuthi uke wazizwa okuningi-futhi mhlawumbe wezwa - i-Dolby Atmos, esetshenzisiwe kuma-movie angama-100 futhi okwamanje ifakwe kuma-theaters angaphezu kuka-300 emhlabeni jikelele. Kukhona futhi uhlelo lweBarco Auro-3D, oluthi, ngo-2014, lusezinkundleni ezingaba ngu-150 futhi lisetshenziswe kuma-movie angaphezu kuka-30. Ngemuva kwezigcawu emphakathini wokukhiqiza ama-movie, noma kunjalo, i-consortium yezinkampani zomsindo we-pro, ehlanganiswe ngokuyinhloko yi-Dolby umncintiswano we-DTS, ibilokhu igxila umbono ohlukile: I-Multi-Dimensional Audio, noma i-MDA.
Ama-DTS aqhutshelwa amademos endaweni yaseshashalazini ekhethekile endaweni yaseLos Angeles.
Ngenhlanhla, ngifika ukuhlala ngaphakathi kwehora lokushayela yilabo beshashalazi futhi ngakwazi ukuthola i-MDA demo enkulu, ekuseni kakhulu ngaphambi kokuba kuvulelwe imidlalo yaseshashalazini. Ngivame ukushiya ukwaziswa okuzungezile kuya kwi-About.com Home Theater Expert uRobert Silva, kodwa ngenxa yokuthi umsindo ozwakalayo uzothatha ama-stereo systems ngelinye ilanga, ngicabanga ukuthi ngizothatha ithuba lokuzwa ukuthi yini i-MDA engayenza.
Landela nami futhi ngizochaza ukuthi i-MDA isebenza kanjani ... nokuthi yikuphi okuzwakalayo.

I-MDA: Indlela Esebenza ngayo
I-About.com Home Theatre yaseshashalazini Uchwepheshe uRobert Silva usechazile kakade i- MDA ngokujulile , kepha nansi okuyisisekelo. Ngesistimu ye-7.1-wesiteshi kumidlalo yaseshashalazini noma i-cinema yezohwebo, unakho phambili kwesokunxele, isikhungo nesipikha sokunene; izinhlangothi ezimbili ezungeze izikhulumi ezungezile izikhulumi ezizungezile ezimbili; futhi eyodwa noma ngaphezulu subwoofers. Abanye abamukeli be-audio / video bangahle bakhishe lokhu kuze kufike ku-9.1 noma ku-11.1 ngokufaka izikhulumi zokuphakama zangaphambili kanye / noma ngaphezulu kwezipikha phakathi kwezipikha ezizungezile zangakwesokunxele / zangakwesokudla nangemuva, usebenzisa i- Dolby Pro Logic IIz , i- Audyssey DSX noma i- DTS Neo: X ukucubungula ukuze uthole iziteshi ezengeziwe.
Amasistimu amancane asithatha lesi sinyathelo ngokuqhubekayo ngokungeza izikhulumi kuleso sihlaba ukuze unikeze imiphumela engaphezulu evulekile neyengqayizivele. Bangakwazi futhi ukufaka izipikha ezingaphezulu ezingakwesokunxele, eziphakathi nezikhulumi ezilungile esivele ngemuva kwesikrini, kanye nezikhulumi ezungezile ezingxenyeni ezibekiwe ngaphezulu kwezigaba ezikhona. Lezi zikhulumi zingasethwa ukuze ziqondiswe ngendlela ngayinye ukuze umphumela womsindo ungahlukaniswa nesinye isikhulumi esithile. Noma umphumela we-panning ungahamba ngokushelelayo nangokungahambisani phakathi kwezemidlalo, uhamba phakathi, uthi, izikhulumi ezizungezile ezingu-16 noma ezingu-20 esikhundleni samaqembu amane ezikhulumi njengaku-7.1.
I-Dolby Atmos, empeleni, inqwaba yeziteshi ezengeziwe ezixhunyiwe kuhlelo olujwayelekile lwe-7.1. Izikhulumi zingabhekiswa emaqenjini njengama-7.1, noma ngabanye ngemiphumela engaphezulu yemithi, futhi kukhona nemigqa emibili yezikhulumi ezifakiwe.
I-MDA ingakwazi ukubhekana nazo zonke izikhulumi ezifanayo, nokuningi - i-demo engiyizwile isebenzisa imigqa emithathu yezikhulumi esihlahleni kanye nezinye izingxenye ezimbili zokuphakama-isikhulumi sezimpikiswano ezizungezile ezisezindaweni ezizungezile ezihlangene, kanye nolunye olwesokunxele, isikhungo nesokudla izikhulumi zokuphakama phezulu kwesikrini.
UJohn Kellogg, umqondisi omkhulu we-DTS weqhinga lezinkampani nezentuthuko wabonisa, "Asiphakamisi ukuthi udinga zonke lezi zikhulumi nge-cinema ecacile. Lokhu kufakwa kwahlanganiswa ngempela njengelabhu ukuze sihlole futhi sibonise inhlanganisela eminingi yezikhulumi. Lokhu kufaka kuhlanganisa ukulungiselelwa kwesikhulumi okwamanje kuma-cinema nalabo abazayo esikhathini esizayo. Kodwa empeleni ukuyisebenzisa konke kuyamjabulisa ngempela. "
Uhlobo olubalulekile lwezobuchwepheshe ne-MDA luyindlela engcono yokucabanga ngokuxuba kanye nensimu yomsindo womsindo.
I-MDA yilokho okubizwa ngokuthi "uhlelo oluthile lwamazwi". Ingqikithi ngayinye yenkhulumomphendvulwano, umphumela ngamunye womsindo, umculo omculo ngamunye wokudlala umculo kanye nesebenza ngayinye kumxube we-soundtrack, uthathwa njengokuthi "into" yomsindo. Esikhundleni sokurekhoda imisindo kumzila othize noma iqembu lamashaneli - ukurekhoda kwe-stereo yesiteshi ezimbili, noma ithrekhi ye-multichannel ye-5.1- noma ye-7.1 yesiteshi, isibonelo - konke ukuthunyelwa njengengxenye yefayela le-MDA. Ifayela liqukethe imethadatha enikeza isixhumanisi esithile noma isikhundla somzimba kunento ngayinye yomsindo noma yomsindo; kanye nesikhathi lapho umsindo uvela khona kanye nomthamo lapho udlala khona.
"Izikhulumi zifana namaphikseli kunjengeziteshi," kusho uKellogg.
I-MDA ingenza "imephu" lezi zivunguli kunoma yikuphi ukukhuluma kwezikhulumi, kusukela ezinkulumeni eziningi ze-cinema yezokuhweba kuya ezimbalwa njengokubili, kusho isethi ye-TV. (Yiqiniso, wonke ubuchwepheshe obuseduze bukaDolby, kufaka phakathi i-Atmos, faka ikhono lokunciphisa zibe iziteshi ezimbalwa njengezindlela ezimbili.) Uma uhlelo lwe-MDA lufakiwe, ochwepheshe uhlinzeka ulwazi mayelana nezindawo zesipikha ekamelweni elithile ohlelweni isofthiwe yokuhumusha ibonisa indlela yokusebenzisa i-array ukuze ikhiqize kakhulu umsindo ngamunye. Isibonelo, uma umphumela ozungezayo kufanele uvela, tshela, ama-degree angama-40 ngaphezu kwakho kanye nama-80 degrees ngakwesokudla, kungenzeka ukuthi angeke abe yisikhulumi ngesikhathi esifanele, kodwa i-MDA ingadala isithombe sephantom sesikhulumi ngaleso sikhathi ngokubethelela ukuxuba okulungile komsindo kuzikhulumi eziseduze lelo phuzu.
Kusukela ekuboneni kwebhizinisi, i-MDA ihluke kakhulu ku-Atmos. Uhlelo lwe-Atmos kanye nohlelo luyimfihlo futhi lulawulwa yi-Dolby. I-MDA, ngokuphambene nalokho, ifomethi evulekile, ibonisa ukusebenzisana phakathi kwezinkampani zemboni ye-cinema kuhlanganise ne-DTS, i-QSC, i-Doremi, i-USL (i-Ultra-Stereo Laboratories), i-Auro Technologies ne-Barco, nama-studios ambalwa kanye nemibukiso.
(Ngalesi sikhathi kufanele ngifake umshwalense. Ngasebenza kuDolby kusukela ngo-2000 kuya ku-2002, kodwa angizange ngithole uxhumano lwezezimali kule nkampani kusukela ngibhala iphepha elimhlophe le-DTS ngonyaka odlule mayelana nobuchwepheshe obungathintani. ukuphishekela futhi ngingenayo inhloso yokuphishekela umsebenzi ngenye inkampani. Anginalo ulwazi olujulile lokukhiqizwa kwe-movie nemiboni yombukiso okuzodingeka ukuba wenze isaziso esilandelayo mayelana nekusasa lenye yalezi zinhlelo futhi ngokukhululekile, mina ungakhathazeki. Ngibhala nje ngedemo epholile engiyibonayo.)

I-MDA: I-Gear
Umqashi wokuthengisa we-QSC uPaul Brink wayesesandleni sokungena kulo lonke uphawu lwama-signal ngaphakathi kwidokodo lokubona indawo ekhethekile. Umgogodla wesistimu yi-QSC Q-Sys Core 500i yedijithali yedijithali yedijithali, enekhono lokusingatha izinzuzo ezingu-128 kanye neziphumo ezingu-128. I-Core 500i ithatha umsindo wedijithali nemethadatha kusuka kuseva ye-Doremi esetshenziselwa ukudlala i-movie kusuka kumabhayisikili anzima anikezwa yi-studio ye-movie. I-Core 500i ixhunywe ku-27 QSC DCA-1622 amplifiers ngokusebenzisa amafomethi amahlanu we-Q-Sys I / O, okuyi-converter adijithali abaguqula i-digital-to-analog. Ungabona zonke lezi zingxenye ngokusondela kukhasi elilandelayo.
Lolu hlelo luneziteshi ezingu-48 zomsindo kanye nesiteshi se- subwoofer esondla ama-subwoofers ayisikhombisa. Njengoba ngichazile ngaphambili, uhlu olulondoloziwe luhlanganisa:
1) Izikhulumi ezingakwesobunxele, eziphakathi nendawo ezilungile ngemuva kwesikrini
2) Izikhulumi ezingakwesobunxele, eziphakathi nendawo ezilungile ngaphezulu kweskrini
3) Imigqa emithathu yezikhulumi eziphahleni egijima ngaphambili
4) Izimpikiswano ezizungezile zigijima nxazonke ezingxenyeni eziseceleni nangemuva
5) Isigaba sesibili esiphezulu sezikhulumi ezizungezile ohlangothini ngalunye lwahlangothini lubekwe cishe ngamamitha angu-6 ngenhla.
Ngokusobala, izindleko zalolu hlobo zingaba phezulu, futhi ukufakwa - ikakhulukazi kwezikhulumi eziphansi - ezibizayo. "I-Scaffolds kwakudingeka ihlelwe futhi ihlulwe izikhathi ezingu-15 ezihlukene ukuphakamisa izikhulumi eziphahleni lapho," kusho uKellogg. "Kodwa akudingeki ukuba kube yinkimbinkimbi. Kungaba yinoma yikuphi indawo yokudlala ekwazi ukuyikhokhela. Emidlalo yaseshashalazini lapho kungenakwenzeka ukufaka izigxobo ezigcwele, sinezincomo ezimbili eduze kwesaphambili, ezimbili ngemuva, futhi enye phakathi nendawo yokulala. Sithola ukuthi kubalulekile ukukunika lelo "lizwi likaNkulunkulu". "
Enye yezinto ezipholile kakhulu nge-demo yilokho i-Brink yayilawula konke kusuka kukhompyutha yakhe ephathekayo ngenkathi ihlezi enkundleni yaseshashalazini kanye nami, futhi ingakwazi ukulungisa kabusha uhlelo ngalunye imizuzwana. Lo mkhono wamvumele ukuba anginike umphumela ogcwele we-MDA nazo zonke izikhulumi, bese ukubuyisela kabusha umsindo kumalungiselelo ekhulumi ahlukene ezindaweni ezifana nalabo asetshenziselwa i-Atmos ne-Auro-3D, kanye ne-standard 7.1.

I-MDA: Okuhlangenwe nakho
Okuqukethwe kwedemo kwakuyi- Telescope emfushane emaminithi angu-10, ongawabona kumasayithi e-movie noma ubukele ku-YouTube (kodwa ku-2.0 kuphela, hhayi 48.1). Kulo demo, kuhlanganiswe ukuxuba okukhethekile kwe-MDA, nemiphumela yomsindo ekhona njengezinto ezifundwayo kanye ne-QSC Core 500i enquma ukuthi yisiphi isikhulumi noma izikhulumi zokuhambisa izinto ezizwakalayo. Ngokusebenzisa i-laptop yakhe, u-Brink wakwazi ukubeka ibalazwe ezintweni ezilungiselelweni ezihlukahlukene engangizixoxe ngaphambilini.
Ukuxuba kwakubonakala kuhle kuzo zonke izigaba ezihlukahlukene, ngisho no-7.1, futhi isici esiyisisekelo somsindo asizange sishintshe. Yini eyashintsha kwaba umqondo wokuvuleka. Njengoba kuqhathaniswa ngokuqondile no-5.1 no-7.1 kwembula ukulinganiselwa kwe-stereo, ukuqhathaniswa okuqondile kwe-MDA nezinye izinto ezivezwe ukulinganiselwa kwabo.
I-telescope yenzeke ngokuphelele ekamelweni elincane le-space spaceship, futhi lokhu, ngokumangalisa, kwabonisa i-MDA ukusebenza ngokugcwele. Lapho umkhumbi ungahambisani nesikhala, imiphumela yomsindo i-bleeps encane ne-bloops kanye nama-hums avela kuwo wonke umshini oseduze ne-cabin. Ngine-MDA, ngithole umqondo ophelele futhi ongenamandla wokuthuthukiswa kunokuba ngifinyelele namanye amafomethi okucwiliswa, nomphumela ongaphezulu kakhulu kunalokho engikuzwile kusuka ku-7.1.
Ngaso sonke isikhathi lapho umkhumbi uhambela indawo entsha, imiphumela ye-front-to-back swooshing yayisheshe ilula nge MDA nase-Atmos, futhi ngenxa yendawo eyengeziwe yokufaka ucingo ngangizwa ukwahlukana okuningi kulezi zindlela.
Ngokusekelwe kulo demo, okungenani, i-MDA izwakala kimi njengento ehamba phambili kakhulu ehamba umsindo. Kodwa-ke, ngiyaqiniseka ukuthi imiphumela yomsindo ixutshwe ukuze ibonise i-MDA. Kuya kubaxhumanisi bokuxuba ukuze basebenzise lokhu okungeziwe. Ukuze i-MDA ibe nenzuzo yomsindo ezinhlelweni zokusebenza zomhlaba wangempela, onjiniyela abaxuba kumele babe nesikhathi, isabelomali nesifiso sokwakha ama mixes asebenzisa amandla awo.
Lokhu kusho ukuthini amasistimu alalelwayo ala ekhaya ? Kusukela ngo-2014, akukho plan for lokho okwamanje, okungenani akukho DTS eyodwa uzimisele ukuxoxa. Kodwa ngamahemuhemu ashayela ngokuqaliswa kwama-receivers ase-Atmos-akwaziyo a-V, kunzima ukucabanga ukuthi i-DTS ayinayo emakethe yasekhaya engqondweni.
