I-DTS Multi-Dimensional Audio Ivakaliwe ... Okwenene
Iinkampani eziliqela zixhasayo ingcamango yeenkqubo ezizungeze i-surroundings ezingaphezulu kwe-7.1 zomsindo, okunye okubizwa ngokuba yi-audio immersive. Usenokuba uvile kakhulu-kwaye mhlawumbi uvile - i-Dolby Atmos, esetyenziswe kumafilimu angama-100 kwaye ngoku ifakwe kwiivenkile ezingaphezu kwama-300 emhlabeni wonke. Kukho nenkqubo yeBarco Auro-3D, leyo, ngo-2014, inama-150 engingqi kwaye isetyenziswe kumafilimu angaphezu kwama-30. Ngenxa yeziganeko zentlalo ye-movie, nangona kunjalo, i-consortium yeenkampani zomsindo ezivakalayo, ezidibaniswe ngokukodwa yi-Dolby umncintiswano we-DTS, iqhube ingcamango ehlukileyo: I-Multi-Dimensional Audio, okanye i-MDA.
I-DTS yenze i demos kwiindawo zokudlala eziseLos Angeles.
Ngenhlanhla, kwenzeka ukuba ndiphile ngaphakathi kweyure yecandelo le midlalo kwaye ndakwazi ukufumana idemo enkulu ye MDA, ekuseni kusasa ngaphambi kokuba le midlalo ivule. Ngokuqhelekileyo ndishiya ingqungquthela engqongileyo kwi-About.com yaseKhaya yezobuchwephesha uSt. Robert Silva, kodwa ngenxa yokuba isandi sokumamitha siya kuthi sichaphazele iinkqubo ze-stereo ngelinye ilanga, ndacinga ukuba ndiza kuthatha ithuba lokuva oko i-MDA enokuyenza.
Landela kunye nam kwaye ndiza kucacisa ukuba i-MDA isebenza njani ... kwaye yintoni efana nayo.

MDA: Indlela Esebenza ngayo
I-About.com I-Home Theater Expert URobert Silva sele sele echaze i-MDA ngokubanzi , kodwa nantsi iziseko. Ngendlela yesikhokelo se-7.1 kwikhaya lezemidlalo okanye kwi-cinema yezorhwebo, ukhangele phambili, iziko kunye nezivakalisi ezilungileyo; izibini zecala elijikelezayo; izibini ezijikelezayo ezimbini; kunye enye okanye ngaphezulu. Abanye abamukeli be-audio / video banokukhaba ukufikelela kwi-9.1 okanye i-11.1 ngokufaka izithethi zokuphakama eziphambili kunye / okanye isibini esongezelelweyo sesithethi phakathi kwesithethi sangasese esisekhohlo / sokunene kunye nesigxina seenxa zonke, usebenzisa i- Dolby Pro Logic IIz , i- Audyssey DSX okanye i- DTS Neo: X ukucubungula ukufumana iziteshi ezingaphezulu.
Izistim zangaphakathi zithatha eli nyathelo ngokungakumbi ngokuzongeza izithethi kwisilwanyana ukubonelela ngeempembelelo ezingaphezulu kunye neengqiqo. Bangakwazi ukongeza ezinye izithethi phambi kwekhohlo, eziphambili nezivakalisi ezilungileyo esele zikho emva kwesikrini, kunye nezithethi ezongezelelweyo ezijikelezayo kwiimpawu ezibekwe ngaphaya kweendawo ezikhoyo. Ezi zithethi zingasetwa ukuze zikwazi ukuqwalaselwa ngokwawo ukuze isiphumo sentsingiselo singasetyenziswa kwisithethi esisodwa. Okanye umphumo wokuphazamiseka ungahamba kakuhle kwaye uhlale ujikeleze i-theatre, uhamba phakathi, uthi, izivakalisi ezijikelezileyo eziphakathi kwe-16 okanye ezingama-20 kunokuba ziphakathi kwamaqela amane ezithethi njenge-7.1.
I-Dolby Atmos, ngokwenene, iqela lezithuba ezongezelelweyo ezixhaswe kwi-7.1 yenkqubo. Izithethi zingabhekiswa kumaqela njengama-7.1, okanye ngabanye kwimiphumo emininzi yokucwina, kwaye kukho iimilo ezimbini zeentetho ezifakwe kwiilesi.
I-MDA ikwazi ukujongana nazo zonke izithethi ezifanayo, kunye nokunye - idilesi endiyivileyo isebenzisa imiqolo emithathu yezithethi kwisilwanyana kunye neendlela ezimbini zokuphakamisa ukuphakama kwezithethi zezithethi ezijikelezayo zendawo engqongileyo, kunye nolongezelelweyo olusecaleni, eliphakathi kunye nolungileyo ukuphakama izithethi phezulu kwesikrini.
UJohn Kellogg, umlawuli ophezulu we-DTS isicwangciso soqhagamshelwano kunye nophuhliso lubonise, "Asinakucebisa ukuba ufuna zonke izivakalisi kwi-cinema edibanisayo. Olu fakelo luye lwahlanganiswa njengebrabhu ukuze sikwazi ukuvavanya size sibonise ukudibanisa ezininzi kwezithethi. Olu fakelo luquka iinkqubo zesikhulumi ezikhoyo kwiikhamera kunye nabazayo kwixesha elizayo. Kodwa ngokuqinisekileyo ukuyisebenzisa konke kuyamnandi. "
Uluhlu oluphambili lwezobuchwepheshe kunye ne-MDA luyindlela ecinga ngayo ngokuxuba kunye nentsimi yesandi.
I-MDA yinto ebizwa ngokuba yi-"system based based" system. Ingqungquthela nganye yeengxoxo, isandi ngasinye sesandi, isandi ngasinye somculo wezwi kunye nesixhobo ngasinye kwisixube somsindo, sithathwa njengesixhobo "somculo". Esikhundleni sokurekhoda izandi kwisitishi esithile okanye iqela leziteshi - ukurekhoda kwe-stereo yesibini, okanye i-soundtrack ye-multi-channel ye-5.1-okanye ye-7.1-umzekelo - bonke bayothunyelwa njengenxalenye yefayile ye-MDA. Ifayile ifaka imethadatha enikezela udidi oluthile okanye isikhundla sendawo kwisandi ngasinye okanye isandi; kunye nexesha apho isandi savela khona kunye nomthamo apho udlala khona.
"Iithethi ziba njengamaphikseli kunjengeziteshi," kusho uKellogg.
I-MDA ingenza "imephu" ngalaba bavumi kwiintetho zeentetho, ukusuka kwiintetho zesithethi kwi-cinema yezorhwebo ukuya kubambalwa, kubini, isethi yeTV. (Kakade, zonke iikhompyutheni zeDolby ezizungezile, kuquka iAmosi, zibandakanya amandla okunciphisa zibe zimbalwa njengeziteshi ezimbini.) Xa inkqubo ye-MDA efakwe, uchwepheshe usondeza ulwazi malunga neendawo zesithethi kwilo gumbi elithile kwinkqubo kwaye isofthiwe yesibonelelo ichaza indlela yokusebenzisa uluhlu ukuze luzalise ngakumbi isandi ngasinye. Umzekelo, ukuba isiphumo esingqongileyo sifanele siphume, sithi, ama-degrees angaphezu kwama-40 ngaphezulu kwakho kunye nama-80 degrees ngakwesokudla, kunokungabi nesikhulumi ngexesha elichanekileyo, kodwa i-MDA ingadala umfanekiso wesithotyana wesithethi kweso sikhundla ngokubethelela ukudibanisa okuchanekileyo kwesandi kwisithethi esiseduze kuloo nqaku.
Ukusuka kwimbono yezoshishino, i-MDA ihluke kakhulu kwi-Atmos. Inkqubo ye-Atmos kunye neprogram i-proprietary kwaye ilawulwa nguDolby. I-MDA, ngokuchaseneyo, ifomati evulekile, ibonakalisa intsebenziswano phakathi kweenkampani zecandelo le-cinema eziquka iDTS, i-QSC, i-Doremi, i-USL (i-Ultra-Stereo Laboratories), i-Auro Technologies kunye neBarco, kunye nee-studios ezimbalwa kunye nomboniso.
(Ngeli nqanaba ndimele ndongeze i-disclaimer.) Ndasebenza kuDolby ukususela ngo-2000 ukuya ku-2002, kodwa andinalo uxhumano lwezezimali kwi-nkampani ukususela oko ndabhala iphepha elimhlophe kwi-DTS kunyaka ophelileyo malunga nobuchwephesha obungathandaniyo. ukuphishekela kwaye akukho njongo yokuqhubela umsebenzi kunye nayiphi na inkampani. andinalo ulwazi olujulile lwemveliso ye-movie kunye nemiboniso yamashishini eya kufuneka ukuba yenze isichaso esinolwazi malunga nekamva lale nkqubo kunye nenyaniso, Andikhathaleli nje. Ndibhalela nje ngedemo epholileyo ndiyibonayo.)

MDA: I Gear
Umninimzi wokuthengisa we-QSC u-Paul Brink wayekho ukundithabatha kuyo yonke ikhonkco yesalathisi kwisixhobo sokuboniswa kwendawo yokuzonwabisa. Ingundoqo yenkqubo i-processor ye-QSC Q-Sys Core 500i yedijithali yedijithali, enegunya lokusingatha iziphumo ezili-128 kunye neziphumo ezili-128. I-500i ye-Core ithatha i-digital audio kunye neetadatha kwi-server ye-Doremi esetyenziselwa ukudlala i-movie kwiimoto ezinzima ezinikezwa yi-studio ye-movie. I-Core 500i ixhunywe kwi-QSC DCA-1622 amplifiers kwiifom ezi-5 ze-Q-Sys I / O, ezixhomekeke kwiinguqu ze-digital-to-analog. Uyakwazi ukubona zonke ezi zixhobo ngokusondeza kwiphepha elilandelayo.
Le nkqubo inamandla angama 48 iziteshi zesandi kunye nesitishi se- subwoofer esondla i-subwoofers ezisixhenxe. Njengoko ndachaza ngaphambili, i-array kwi-theatre yayiquka:
1) Izithethi ezisekhohlo, eziphambili kunye ezilungileyo emva kwesikrini
2) Izithethi ezisekhohlo, eziphambili nezisekunene kwesikrini
3) Imiqolo emithathu yeentetho eziphambili zihamba phambili ukuya ngasemva
4) Iintetho ezijikelezayo zijikeleza ngeenxa zonke kunye neendonga zangasemva
5) Udidi lwesibini oluphezulu lwezithethi ezijikelezileyo kwicala ngalinye lecala lusekwe malunga neenyawo ezi-6 ngaphaya kweyona ndawo.
Kucacile ukuba, iindleko zolu hlobo ziphezulu, kwaye ukufakwa - ngokukodwa kweziithethi zesilingi - ezibiza. "I-Scaffolds kwafuneka yenziwe kwaye ihlanjwe ngamaxesha ahlukeneyo ama-15 ukuphakamisa izithethi ezisezantsi apho," kusho uKellogg. "Kodwa akufanele ukuba yinto enzima." Inokuba yinto enokwenza ukubeka iiflethi ezipheleleyo, sivame ukucetyiswa ezimbini ngasekuqaleni, ezimbini ngasemva, kwaye enye ephakathi kwendawo yokuhlala. Siyifumana into ebalulekileyo ekunikeni ukuba 'ilizwi likaThixo liphumelele.'
Enye yezinto ezipholileyo kakhulu ngeDemo yiyo yokuba iBrink yayilawula konke ukusuka kwikhompyutheni yakhe yekhomputha xa ihleli kwindawo yokudlala kunye nam, kwaye iyakwazi ukuyibuyisela kwakhona inkqubo ngemizuzwana. Olu xanduva lwamvumela ukuba anginike impembelelo epheleleyo ye-MDA nazo zonke izithethi, aze aphinde ahlaziye isandi kwizicwangciso zesithethi ezahlukileyo kwiindawo ezifana nezo zisetyenziselwa i-Atmos kunye ne-Auro-3D, kunye ne-standard 7.1.

MDA: Amava
Iimpawu zedemo ye- Telescope yimizuzu eyi-10 enokufutshane, ongayibona kwisayithi yee-movie okanye ubukele kwi-YouTube (kodwa ngo-2.0 kuphela, kungekhona 48.1). Kwi-demo, ukuxuba okukhethekileyo kwe-MDA kwakhiwe, kunye nemiphumo yesandi esele ikhona njengezinto ezifunyenwe kunye ne-QSC Core 500i isigqibo sokuba yeyiphi isithethi okanye izithethi ukuhambisa izinto ezivakalayo. Ngokusebenzisa i-laptop yakhe, uBrink wakwazi ukupaka iimpawu kwiinkqubo ezahlukeneyo ezazixutyushwa ngaphambili.
Umxube uvale kakuhle kuzo zonke iindidi ezihlukeneyo, nokuba ngu-7.1, kunye nesimo esisisiseko sesandi asitshintshi. Yintoni eyatshintshileyo yayingumqondo wokuvuleka. Kanye ngokuthelekiswa okuthe ngqo kunye no-5.1 no-7.1 kubonisa ukuba ukulinganiselwa kwe-stereo, ukuthelekiswa okuthe ngqo kwe-MDA kunye nezinye izinto eziye zabonisa ukulinganiselwa kwazo.
I-Telescope yenzeke ngokupheleleyo kwikhabini le-spaceship encinci, kwaye oku, ngokumangalisayo, yabonisa i-MDA ukuba isebenze ngokupheleleyo. Xa iinqanawa zingaphumeleli kwi-space, iziphumo zomsindo zincinci kakhulu kunye neengqungquthela kunye nama-hums kuwo wonke umatshini ojikeleze kwikhabhinethi. Nge-MDA, ndandifumana ingqiqo epheleleyo kunye engapheliyo yokukhupha ngaphezu kokuba ndifumene namanye amafomathi ahlambulukileyo, kunye nempembelelo engaphezulu kunokuba ndivele kwi-7.1.
Ngethuba eli xesha iinqanawa zazingena kwindawo entsha, i-front-back-back-back swooshing iziphumo zazihamba kakuhle kunye ne-MDA kunye ne-Atmos, kwaye ngenxa yoluhlu olongezelelweyo lwendandatho ndava ukungafani kwale miphumo.
Ngokusekelwe kule demo, ubuncinci, i-MDA isandi kum njengento ephakamileyo kunayo yonke eyenza isandi. Kodwa ke, ndiqinisekile ukuba iziphumo zomsindo zaxutyushwa ukuze zibonise i-MDA. Kuya kubanjineli bokuxuba ukuba basebenzise olu buninzi. Ukuze i-MDA ibe nenzuzo yonyana kwizicelo zehlabathi zangempela, iinjineli zokuxuba ziya kufuneka zibe nexesha, uhlahlo lwabiwo-mali kunye nomnqweno wokudala i-mixes exhaphaza amandla ayo.
Yintoni le nto ithetha kwiinkqubo zomsindo wekhaya ? Ukususela ngo-2014, akukho sicwangciso saloo nto, ubuncinane akukho DTS enye ekulungele ukuxoxa. Kodwa ngamahemuhemu endijikelezayo malunga nokuqaliswa kwe-Atmos-abanako ukufumana i-A / V, kunzima ukucinga ukuba i-DTS ayinayo imakethe yasekhaya engqondweni.
