Indawo yaseshashalazini yasendlini inabantu abaningi abakhetha ukuxhumana ngokuthumela izimpawu zomsindo namavidiyo ukuze usethe izithombe kwi-TV yakho noma iphrojekithri yevidiyo, futhi uzwe umsindo kusuka ohlelweni lwakho lokulalelwayo nezikhulumi. Uhlobo olulodwa lokuxhumeka komsindo olwenziwe ukuthi lusetshenziselwe umsindo luxhumano lwe-Digital Optical.
Ukuthi Ukuxhumeka Kokukhanya Kokudijithali Kuyini
Ukuxhumeka kwe-digital optical uhlobo lokuxhumeka ngokomzimba olusebenzisa ukukhanya ( fiber optics ) ukudlulisa idatha yedijithali evela kumshini osebenzayo ohambisanayo kudivayisi edlala ukudlala ngokusebenzisa ikhebula elenziwe ngokukhethekile kanye nomxhuma.
Idatha yomsindo iguqulwa kusuka kumathanga kagesi kuya ekukhanyeni kwempuphu ekupheleni kokudlulisa, bese ubuyela emuva ekufakeni kwezwi kagesi ekupheleni kokuthola. Ama-puls sound kagesi ahamba ngedivaysi ehambisanayo ebaqinisa ukuze bakwazi ukuzwa ngezikhulumi noma nge-headphones.
Ngokuphambene nenkolelo evamile, ukukhanya akukhiqizi i-laser - kodwa nge-bulb encane ekhanyisa i-LED eveza umthombo wokukhanya odingekayo ekupheleni kokudlulisa, okungathunyelwa ngekhebula le-fiber optical ekuxhumaneni okuhambisanayo ekupheleni kokuthola, iphi lapho iguqulwa khona kodwa kodwa ku-pulses kagesi engakwazi ukuhlelwa kabusha / isetshenziswe yeshashalazi yasekhaya noma isamukeli se-stereo futhi ithunyelwe kuzikhulumi.
Izicelo zoxhumano lwe-Digital Optical
Endaweni yaseshashalazini yasekhaya neyasekhaya, uxhumano lwe-digital optical lisetshenziselwa ukudlulisa izinhlobo ezithile zempawu zomsindo wedijithali.
Amadivaysi anganikeza lolu khetho lokuxhumeka afaka phakathi abadlali be-DVD, abadlali be-Blu-ray Disc, iMedia Streamers, Amabhokisi e-Cable / Satellite, Abamukeli be-Home Theatre, imivimbo eminingi yemisindo, futhi kwezinye izimo abadlali beCD kanye nabamamukelayo abasha abasha.
Kubalulekile ukuthi uqaphele ukuthi nakuba ukuxhumanisa kwe-digital optical kungafakwa kuma-DVD / Blu-ray disc abadlali noma abasakaza ama-media, aziklanyelwe ukudlulisela izimpawu zevidiyo. Lokhu kusho ukuthi uma uxhuma i-DVD / Blu-ray / Media streamer futhi ufuna ukusebenzisa inketho yokuxhumanisa optical digital, okuwukuphela komsindo kuphela. Ukuze ividiyo, udinga ukwenza okuhlukile, okuhlukile, uhlobo lokuxhumeka.
Izinhlobo zomsindo wedijithali ongadluliswa ngoxhumo lwe-digital optical zihlanganisa i -PCM ye-Stereo emibili , i- Dolby Digital / i-Dolby Digital EX, i-DTS Digital Surround, ne-DTS ES .
Kubalulekile ukuqaphela ukuthi izimpawu zomsindo wedijithali, njenge-PCM ye-5.1 / 7.1 yamanethiwekhi amaningi, i- Dolby Digital Plus , i- Dolby TrueHD , i- Dolby Atmos , i- DTS-HD Master Audio , i- DTS: X , ne- Auro 3D Audio ayikwazi ukudluliswa nge-Digital Optical ukuxhumana - Lawa mafomethi adinga uxhumano lwe- HDMI .
Isizathu salokhu umehluko wukuthi lapho kuthuthukiswa uxhumano lwe-digital optical, lwenziwa ukuba luhambisane namazinga womsindo wedijithali ngaleso sikhathi (ikakhulukazi ukudlala kwe-CD yesiteshi), engabandakanyi i-PCM ye-5.1 / 7.1 yesiteshi, i- Dolby Digital Plus, I-Dolby TrueHD, i-Dolby Atmos, i-DTS-HD I-Master Audio, noma i-DTS: X. Ngamanye amazwi, amakhodi e-digital optical ayinalo ikhono lomkhawulokudonsa ukusingatha ezinye zefomethi ezishaywayo zendawo yaseshashalazini entsha.
Kubalulekile ukuveza ukuthi nakuba bonke abatholi be-Home Theater, abadlali beDVD, abaningi beMedia Streamers, ama-Cable / Satellite Amabhokisi, kanye nabathile abathile be-Stereo Receivers banokukhethwa kokuxhumeka kwe-Digital Optical, kunezinye abadlali be-Blu-ray Disc abaqedile i-Digital Optical ukuxhumeka njengenye yezinketho zokuxhumeka komsindo, ukhetha ukuxhuma kuphela kwe-HDMI kokubili kokulalelwayo nevidiyo.
Ngakolunye uhlangothi, abadlali be-Ultra HD Blu-ray , ngokuvamile bafaka inketho ye-optical audio output output, kodwa kuya kumenzi - akuyona isici esidingekayo.
Ngamanye amazwi, uma une-receiver yekhaya yaseshashalazini ene-Digital Optical uxhumano lokuxhuma, kodwa ayihlinzeki ngokukhetha kokuxhumeka kwe-HDMI, qiniseka ukuthi uma uthengela isidlali esisha se-Blu-ray noma i-Ultra HD Blu-ray Disc umdlali, ukuthi wenza, ngempela anikele, inketho yokuxhuma ye-Digital Optical yomsindo.
QAPHELA: uxhumano lwe-Digital Optical lubizwa nangokuthi uxhumano lwe-TOSLINK. I-Toslink ifinyelele "i-Toshiba Link", ngoba i-Toshiba yinkampani eyayilungisa futhi yangenisa emakethe yabathengi. Ukuthuthukiswa nokusetshenziswa koxhumano lwe-digital optical (Toslink) kufanelana nokufakwa kwefomethi ye-CD yomsindo, lapho kusetshenziselwa khona kuqala kuma-CD abadlali abaphezulu kakhulu ngaphambi kokuthi yande ibe yingxenye yayo yamanje njengengxenye yezwe lomculo wezemidlalo yaseshashalazini.
Okubalulekile
Ukuxhumeka kwe-Digital Optical kungenye yezinketho eziningana zokuxhumanisa ezingasetshenziselwa ukudlulisela izibonakaliso zomsindo ngokwamadivaysi omthombo ohambelana nama-receiver yasekhaya (futhi, kwezinye izimo, isamukeli se-stereo).
Ukumba ngokujulile emlandweni, ukwakhiwa, kanye nokucaciswa kobuchwepheshe bokuxhuma kwe-Digital Optical / Toslink kubhekisela ku-TOSLINK Umlando Wokuxhumanisa Nezingqalasizinda (nge-Audioholics).
Kukhona olunye uxhumano lwe-digital olutholakala olunezincazelo ezifanayo njenge-Digital Optical, futhi yi- Digital Coaxial , okudlulisela izignali zomsindo wedijithali ngaphezu kwentambo yendabuko, kunokukhanya.
