Ukufinyelela ama-Dolby, i-DTS, ne-PCM Imifula Audio kusukela kumdlali we-Blu-ray Disc
Ifomethi ye-Blu-ray disc ayihlinzeki kuphela ngesipiliyoni sokubuka esithuthukisiwe kodwa futhi inikeza ukulalela okuzwakalayo okuzungezile okuphezulu.
Abadlali be-Blu-ray Disc banikeza izinketho eziningana zokusetha zokukhishwa kwe-audio nevidiyo, kuye ngokuthi unomdlali wakho ohlangene kanjani nesitholi sakho semidlalo yaseshashalazini .
Ukuze ulalele, uma uxhuma isidlali sakho se-Blu-ray Disc kwi-homemaker receiver yakho nge- HDMI , kunezilungiselelo ezimbili zokukhishwa komsindo ezitholakalayo: I- Bitstream ne- PCM (aka LPCM) . Ngokuphathelene nekhwalithi yomsindo wangempela, kungakhathaliseki ukuthi unomsindo wakho we-HDMI womculo we-Blu-ray disk esethwe ku-PCM noma i-Bitstream ayinandaba. Noma kunjalo, nansi okwenzekayo uma ukhetha noma ukuhlela:
I-PCM Option
Uma usetha isidlali se-Blu-ray Disc ukukhipha umsindo njenge-PCM, umdlali uzokwenza ukukhipha ukulalelwayo kwezo zonke izingoma ezihambisanayo zeDolby / Dolby TrueHD kanye ne- DTS / DTS-HD ngaphakathi ngaphakathi futhi uthumele isignali yomsindo ekhokhisiwe ngesimo esingagxiliwe isithandwa semidlalo yaseshashalazini. Ngenxa yalokho, umamukeli wakho wendawo yaseshashalazini ngeke adingeke enze noma yikuphi ukucushwa kokulalelwayo ngaphambi kokuba umsindo uthunyelwe ngesigaba se-amplifier kanye nezikhulumi. Ngalolu khetho, umamukeli wendawo yaseshashalazini uzobonisa igama elithi "PCM" noma "LPCM" ekubonisweni kwepaneli langaphambili.
I-Bitstream Option
Uma ukhetha i-Bitstream njenge-setting ye-HDMI yokukhipha umsindo yomsindo wakho we-Blu-ray, umdlali uzodlula ama-decoder wangaphakathi we-Dolby no-DTS womsindo futhi athumele isignali engafakiwe engakamukeli we-HDMI ehambelanayo yasekhaya. Umamukeli wendawo yaseshashalazini uzokwenza konke ukukhipha ukulalelwayo kwesignali engenayo. Ngenxa yalokho, lo mamukeli uzobonisa i-Dolby, i-Dolby TrueHD, i-DTS, i-DTS-HD Master Audio, i- Dolby Atmos , i- DTS: X , njll ... ekubonisweni kwepaneli langaphambili kuye ngokuthi yiluphi uhlobo lwesignali encane ekhonjisiwe.
QAPHELA: I-Dolby Atmos ne-DTS: X izakhiwo zomsindo ezizungezile zitholakala kuphela kumdlali we-Blu-ray Disc ngokusebenzisa inketho ye-Bitstream setting. Alukho abadlali be-Blu-ray Disc abangakwazi ukukhetha lezi zakhiwo ngaphakathi ku-PCM bese bedlulisela ukuthi kuyisamukeli semidlalo yaseshashalazini.
Unesinqumo sokuthi iyiphi isilungiselelo oyisebenzisayo (i-Bitstream noma i-PCM), futhi njengoba kushiwo ngenhla, noma ngabe ukulungiselelwa kufanele kube nekhwalithi efanayo yezwi (ukukhumbula engqondweni yeDolby Atmos / DTS: X exceptions).
Umsindo wesibili
Kunesinye isici okufanele sicatshangelwe: Umsindo Wesibili. Lesi sici sinikeza ukufinyelela kokuhlaziya okulalelwayo, umsindo ochazayo, noma amanye amathrekhi alalelwayo angeziwe. Uma ukufinyelela kulezi zinhlelo zomsindo kubalulekile kuwe, bese ugcina i-Blu-ray isidlali esivela ku-PCM sizohlinzeka ngemiphumela engcono kakhulu yekhwalithi.
Uma uhlanganisa izilungiselelo zomsindo we-bitstream nesesibili, i-disc-Blu-ray player izoba "phansi-res" amafomu azungezile, njenge-Dolby TrueHD noma i-DTS-HD, kwiDolby Digital noma i-DTS ejwayelekile ukuze ukwazi ukucindezela izinhlobo zombili izimpawu zomsindo ezingeni elifanayo lomkhawulokudonsa. Kulesi simo, umamukeli wendawo yaseshashalazini uzobona isignali njengeDolby Digital ejwayelekile bese ekhetha kahle.
I-HDMI vs Digital Optical / Coaxial Connections
Ngemuva kokuthi unqume ukuthi yiziphi izilungiselelo zomsindo ofuna ukuyisebenzisa ukudlulisa umsindo kusuka kumdlali wakho we-Blu-ray Disc kuyo yonke indawo yakho yaseshashalazini yasendlini, udinga ukunquma ukuthi hlobo luni lokuxhumene oludingayo ukusebenzisa.
Uma usebenzisa i- digital optical noma i-digital coaxial uxhumano lokukhetha kusuka kumdlali wakho we-Blu-ray wediskithophu kumamukeli wakho wasekhaya wasekhaya (okunokwenzeka uma umamukeli wakho wendawo yaseshashalazini engenakho uxhumano lwe-HDMI), ungakhetha futhi i-PCM noma i-Bitstream yokukhethwa kokukhipha kanye lezo zixhumanisi.
Kodwa-ke, kulokhu, ngenkathi inketho yokukhipha okukhiphayo ingathumela isignali ejwayelekile yeDolby Digital noma i-DTS 5.1 esondelene nomuntu owamukelayo ukuze uhlaziye ngokuqhubekayo, inketho ye-PCM izothumela kuphela isignali yesiteshi ezimbili. Isizathu salokhu ukuthi i-digital optical noma i-digital coaxial cable ayinayo amandla okwenyuka kwe-bandwidth ukudlulisela isignali yomsindo ozungezile, ongenakunyakaziswa, ogcwele njenge-HDMI uxhumano.
Kumele futhi kubonakale ukuthi amakhodi e-digital optical / coaxial ayikwazi ukudlulisa i-Dolby Digital Plus, i-Dolby TrueHD, noma i-DTS-HD Master Audio kunoma yiliphi uhlobo noma i-PCM ifomu - i-HDMI iyadingeka.
QAPHELA: Nakuba ingxoxo engenhla igxile kwi-Bitstream vs PCM ngokuphathelene nabadlali be-Blu-ray Disc, ulwazi olufanayo lungasetshenziswa futhi kuma -Players Disc Disc-ray Blu-ray .
