Isingeniso Kumjikelezo Uzungeza
Uma unayo ibha yomsindo endala, i-HDTV, noma umamukeli wendawo yaseshashalazini, ungase ubone isilungiselelo kwimenyu yokubeka umsindo ebizwa ngokuthi "Umjikelezo Uzungeza" - kodwa yini ngempela?
Esikhathini eside ngaphambi kokuthi i- Dolby Atmos , ne- DTS: X zifake izakhiwo zomsindo, inkampani eyaziwa ngokuthi i-SRS Labs isebenza ngezindlela zokwakha ifomethi yomsindo ozungezile eyayigxilile kakhulu kunamafomethi eDolby ne-DTS ayatholakala ngaleso sikhathi.
Ngesikhathi sokuthuthukiswa kwalo, i-Circle Surround yavakashela umsindo ozungezile ngendlela ehlukile. Ngenkathi i- Dolby Digital / Dolby TrueHD ne- DTS Digital Surround / i- DTS-HD indlela ye- Audio Omusha ehambisana nomsindo ovela endaweni eqondile yokuqondisa (imisindo ethile evela ezikhulwini ezithile), Umjikelezo Surround ugcizelela ukucwiliswa komsindo.
Yeka ukuthi Isiyingi Sibheke Kanjani Imisebenzi
Ukuze ufeze lokhu, umthombo ovamile we-audio umsindo ukhonjiswe phansi eziteshini ezimbili, bese uphinde uhlelwe kabusha kumashaneli angu-5.1 uphinde uphinde ubuyiselwe kuzikhulumi ezingu-5 (ngaphambili kwesokunxele, isikhungo, phambili ngakwesokudla, okuzungezile kwesokunxele, okuzungezile kwesokudla, kanye ne-subwoofer) ngendlela yokuthi udale umsindo ozwakalayo ngaphandle kokulahla iziqondiso zencazelo yokuqala yomthombo wesiteshi 5.1. Futhi, i-Circle Surround ingaphinde yandisa izinto ezimbili zomthombo wesiteshi zibe yilapho egcwele isipiliyoni esizwakalayo sokulalela umsindo wesiteshi esingu-5.1.
Yungeza izicelo ezizungezile
Ngokungeziwe, kungenzeka ukuthi umculo nomculo we-movie baqoqe okuqukethwe ngaphakathi kwefomethi ye-Circle Surround, futhi uma idivaysi yokudlala (i-TV, ibha yomsindo, isamukeli semidlalo yaseshashalazini yasendlini) ine-Circle Surround encoder, umlaleli angakuthola ngempela umphumela ozwakalayo wezungezile ozungezile ohlukile kulokho ozobhekana nakho kusuka kumafomethi aqondile eDolby Digital noma e-DTS.
Isibonelo, kunamanani ama-CD alalelwayo abhalwe nge-Circle Surround. Lezi CD zingadlalwa kunoma yimuphi umdlali we-CD, ne-Circle Surround-encoded idlule ngemiphumela ye-analog stereo yomdlali bese ihlelwe yumamukeli wendawo yaseshashalazini ene-Circle Surround encoder. Uma isamukeli semidlalo yaseshashalazini singenalo i-decoder efanele, umlaleli uyakwazi ukuzwa umsindo we-standard stereo CD. Bona ukuphela kwalesi sihloko ngokuxhumanisa kuhlu lwe-CD yama-CD ekhokhelwe ku-Circle Surround okungenzeka itholakale.
Ukuzalwa kwangaphakathi kwamuva kwe-Circle Surround (2001) kubizwa ngokuthi i-Circle Surround II, okwandisa imvelo yangempela ye-circle Circle Surround kusuka ezinhlanu kuya kwesithupha (ngaphambili ngakwesokunxele, phakathi, phambili ngakwesokudla, okuzungezile kwesokunxele i-subwoofer), futhi wanezela okulandelayo:
- Ukuthuthukiswa kokucubungula nokuthuthukiswa kwendawo.
- Ukuthuthukiswa kwe-Bass
- Ibanga eligcwele lemvamisa yazo zonke iziteshi.
- Ukuhlukaniswa kwesiteshi okuthuthukisiwe.
Ulwazi oluningi
Izibonelo zemikhiqizo yangaphambilini efaka phakathi i-Circle Surround noma i-circle Circle Surround II ihlanganisa:
I-Marantz SR7300 ye-AV Receiver (2003) - Funda ukubuyekeza kwami
I-Vizio S4251w-B4 5.1 Isiteshi se-Sound Bar Home Theatre System (2013) - Funda Ukubuyekeza
Ukufakwa ohlwini kwe-Circle Ama-CD ahambelana ne-surrounds
Ubuchwepheshe obumayelana ne-Sound Surround ekuqaleni okwakhiwa yi-SRS futhi kudluliselwe ku-DTS kufaka phakathi i-TruSurround ne-TruSurround XT. Lezi zimemo zokucubungula zomsindo zinekhono lokuthola imithombo yemisindo eningi yeziteshi ezizungezile, njengeDolby Digital 5.1 futhi iphinde iphinde ibuyele isipiliyoni sohlu lwezansi nxazonke usebenzisa izikhulumi ezimbili kuphela.
Kusukela ukuthathwa kwe-SRS Labs nge-DTS ngo-2012, i-DTS ithathe izakhi ze-Circle Surround no-Circle Surround II futhi yazifaka ku-DTS Studio Sound ne-Studio Sound II.
I-DTS Studio Sound inezela izici ezifana ne-Volume Leveling, ukuze kube lula ukushintsha phakathi kwemithombo kanye nalapho kushintsha iziteshi ze-TV, ukuthuthukiswa kwebhasi okuthuthukisa ama-bass ezikhulwini ezincane, iSomlomo EQ yokulawulwa kwezinga eliphezulu lesikhulumi, nokuthuthukiswa kwe-Dialog.
I-DTS Studio Sound II ikhulisa ukuguquguquka komsindo okuzungezile okuqhubekayo ngokuqhubekayo ngokunemba kokuqondisa kokuqondisa, kanye nokuthuthukiswa okuyisisekelo okuyisisekelo. I-Studio Sound II iphinde ihlanganise inguqulo ehlukahlukene ye-DTS TruVolume (eyayiyi-SRS TruVolume) ehlinzeka ngokulawula okungcono kwe-voltage fluquation kokubili ngaphakathi kokuqukethwe, naphakathi kwemithombo.
I-DTS Studio Sound / II ingahlanganiswa kokubili ekhaya (ama-TV, imisindo yemisindo), ama-PC / ama-laptops, namadivayisi weselula.
