DTS Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele DTS?

DTS (Digital Theater Systems) is a multi-channel audio format for cinema and home theater.

Ingabe i-DTS idinga ukudlalwa nge-headphones?

Akunalutho - lokhu kuyi-cinema delivery bitstream. I-DTS stream ifaka i-multichannel mix esetshenziselwa ukucutshungulwa yi-AV receiver futhi ithunyelwe kuma-speakers angempela abekwe endaweni. Ifoni noma i-laptop kufanele ivuleke ngezansi kuma-channels amabili ngaphambi kokuba ikwazi ukudlala ngaso sonke isikhathi, futhi le-downmix ivame ukuba ne-soundless futhi i-flatter kune-stereo track e mastered njenge-stereo. Guqula uma indawo esiya kuyo i-headphones; gcina uma indawo esiya kuyo i-receiver. I-DTS's bitrate ephezulu inikeza i-headroom engaphezulu kune-Dolby Digital, futhi abathola i-cinema yasekhaya bayiphatha njengendlela ekhokhelwayo.

Ingabe ubuhle bulahlekile kuhele DTS?

Noma yini encoder yakuqala ekhetha ukuyisusa, futhi ayikwazi ukubuyiselwa. DTS icindezela ngokumodela lokho okungekuqaphela indlebe - imisindo ekhululekile ehlala ngaphansi kwezikhulu, iziqongo eziphezulu zokulalela - futhi isuse ngokuqhubekayo. Ku-bitrate ephephile engeke ikwazi ukulalela wonke umuntu. Okunye okungaba khona kubuyiselwa emuva, ngakho ukushintshana kufomethi engalahlekelwa yisimo samanje ngaphandle kokubuyisela okungaphambili. I-DTS iyisandi esiningi esilahlekile esingenazo izintambo esiphezulu kakhulu kuna-AC-3 — ngokuvamile 768 kuya ku-1509 kbps nge-5.1.

Kungani umsindo ophumayo ecwecweni uhlala DTS?

Ngenxa yokuthi isilinganiso sediski siyibiza ngokuthi. Umdlali wadinga ukucisha umsindo kwihardware esebenza kahle eqinile ngaphandle kwesoftware noma ukuhlaziywa, ngakho ukucaciswa kwakhetha uhlobo olulodwa futhi wonke umsindo ocindezelwe kusukela wathwala. Lokhu kusho ukuthi umthumeli uphatha ngaphandle kokukhathazeka futhi umsakazo awuzowuchofoza — uhlobo lwahamba lapho isilinganiso sihamba khona, futhi akukho kuphi. I-DTS iyi-Digital Theater Systems audio, i-cinema-derived rival to Dolby Digital evela ku-laserdisc ne-DVD kusukela ngo-1993.

Kungani ihele lami DTS livela ngaphandle kwegama lesiqongo noma isithombe?

Ngenxa yokuthi ifomu alikho indawo efanele yokuzigcina. DTS yacaciswa ngaso sonke isikhathi ngaso sonke isikhathi, ngaphandle kwendawo ejwayelekile yesihloko, i-album noma isithombe sokuzivikela, ngakho abadlali babuyela emuva ukukhombisa igama lefayela. Ukushintshana kufomethi ephawuliwe kwenza i-library ifinyeleleke — amathegi abhalwe ngesikhathi sokuguqulwa ngaphezu kokubuyiselwa, ngakho-ke cabanga ukugcwalisa noma yini engingakhombisi i-source. I-DTS license isho ukuthi i-TV, i-soundbars kanye ne-browser ngayinye iyisiyeka, ngakho-ke kufanele ibe yi-AAC noma i-AC-3 ukuze isebenziseke.

Ingabe ihele DTS lingathwala i-5.1 surround mix?

Yebo - ifomu liphatha iziqhagamshelanisi ezingaphezu kwezingu-2 ngokufanele, ngakho-ke ukuhlanganisa okugqamile kugcina isakhiwo sesiqhingi saso ngaphandle kokucindezelwa kwe-stereo ngendlela efanele. Uma ukhuluma ngayo njenge-surround kuxhomekeka kukuphela kokuphela: umlayezo uzosusa wonke ama-channels, ifoni izocindezela phantsi ngesikhathi sokudlala ngaphandle kokukhathazeka. Ukushintshana ku-stereo-only format kwenza ukuthi ucindezelwe ngokuqhubekayo.

Ingabe kubaluleke ukuthi DTS ingaphezu kweminyaka engu-30?

Ubudala bukhona akuyona inkinga - amafomethi amaningi onyaka akhona alungile, ngokucacile ngoba konke kudlule iminyaka eminingi ukuwafaka. Okubalulekile ukuthi unyaka uthathe isinqumo: amafayela amancane, amaprosesa aphansi, akukho nethiwekhi, futhi amakhono angeke afune umuntu. lapho amanani ahlala khona, ifomu lilungile. lapho ayikho, lena yisizathu sokushintsha.

Kungani ihele DTS alidlalwa kumsakazo wami?

Amabhuleki aqopha uhlu oluncane, oluqinile lwefomethi yomsindo futhi DTS ungaphandle kwalo, ngakho ihele likhuphuka endaweni yokudlala noma umdlali ukhombisa iphutha. Isofthiwe yedesktop enesethingi se-codec esibanzi ivula ngaphandle kwezinkinga. Uma umsindo udlala kukhasi le-web, ukushintsha kuyinto elungile — akukho ukumiswa komdlali kuzongeza umbhalo oqoshiwe umbhukeli awuthumeli.

Yini i-bitrate okufanele ngiyiguqule amafayela ami DTS?

Uhlu lwendawo esiya kuyo, hhayi umsuka. Ukudlalwa kwengoma, 256 kuya ku-320 kbps kucacile kuwo wonke umuntu olalelayo; ukukhuluma nokulalela ipodcasts, 96 kuya ku-128 kbps kuningi futhi kushiya ihele ngaphesheya. Ukungenisa umsindo ngaphezu komsuka we-bitrate kulahlekile isikhala — kugcina umsindo osele udlulele nge-lossy pass futhi akubuyiseli lutho umngenisi wokuqala olahlekile.

Ingabe ukusebenzisa DTS kuthatha ilayisense lepatenti?

Ukuguquka kugcina umsuka wezinga — 48 kHz uhlala 48 kHz, 44.1 kHz uhlala 44.1 kHz — ngoba ukusatshalaliswa kabusha kubiza kakhulu futhi akusebenzi uma akukho okudingayo. Iziphuzo zikhona: ama-CD omsindo adinga u-44.1 kHz, abanye abadlali behardware abadala bamukela okuthile, futhi amapayipi omsindo avame ukudinga u-16 kHz. Misela izinga ngokucacile kulezi zinkinga bese ushiya icala linye.

Ingabe ngingenza ngiphinde ngibize isiqephu endaweni yokushintsha DTS?

Kunzima kakhulu, futhi kufanelekile ukuqonda ukuthi kungani: isithonjana siyisihloko, ngenkathi ama-bytes ngaphakathi kufakwe ngefomethi eyodwa ekhethekile. Ukushintsha igama kwenza ihele igama lakhe lithembisa okuthile okuqukethwe kwayo akusho ukunikela, futhi noma yini evula ihele noma liyiphoqa noma liyifunda kabi. Ukuphela kwephutha elincane yifomethi ezimbili ezikhona ngokusemthethweni ibhokisi elifanayo ngaphansi kwezinhlamvu ezahlukene — futhi ngisho lapho ukuphinda uphinde
