Yuav Paub
- Digital audio sib txuas siv fiber ntau optics thiab pom muaj nyob hauv qee lub tsev ua yeeb yam thiab lub tso suab tsheb.
- Cov khoom siv uas txhawb nqa cov kev sib txuas kho qhov muag muaj xws li lub thawv cable, game consoles, Blu-ray players, thiab TVs.
- Qee ntau cov qauv xws li Dolby Atmos thiab DTS: X tsis tuaj yeem siv cov kev sib txuas kho qhov muag.
Kab lus no piav qhia qhov kev sib txuas ntawm cov khoom siv kho qhov muag yog dab tsi thiab teev cov khoom siv uas txhawb nqa tus qauv no.
Digital Optical Connection yog dab tsi?
Digital optical yog hom kev sib txuas suab hauv tsev ua yeeb yam thiab lub tso suab rau lub tsheb. Cov khoom siv tsawg dua tau ua nrog cov khoom siv kho qhov muag tso tawm cov chaw nres nkoj, yog li nws yog ib qho tseem ceeb kom nkag siab txog hom kev sib txuas uas koj cov khoom siv suab tuaj yeem txhawb nqa.
Digital optical yog ib qho kev sib txuas ntawm lub cev uas siv fiber ntau optics los hloov cov ntaub ntawv suab los ntawm cov khoom siv sib xws rau cov khoom siv ua si tau siv tau tshwj xeeb uas tsim los ntawm cable thiab connector. Cov ntaub ntawv suab tau hloov dua siab tshiab los ntawm digitally encoded hluav taws xob pulses mus rau lub teeb ntawm kev sib kis kawg siv lub teeb ci LED.
Tom qab lub teeb dhau los ntawm digital optical cable mus rau nws qhov chaw, lub teeb pulses hloov rov qab mus rau hluav taws xob pulses uas muaj cov ntaub ntawv suab. Cov hluav taws xob lub suab pulses tom qab ntawd mus ntxiv los ntawm cov khoom siv uas siv tau (xws li lub tsev ua yeeb yam lossis lub tso suab receiver) uas ua rau lawv, thaum kawg hloov lawv mus rau cov teeb liab analog thiab nthuav dav rau lawv kom lawv hnov los ntawm cov neeg hais lus lossis lub mloog pob ntseg.
Lwm lub npe rau kev sib txuas ntawm cov khoom siv kho qhov muag yog TOSLINK kev sib txuas. TOSLINK yog luv luv rau "Toshiba Link" txij li Toshiba yog thawj lub tuam txhab los tsim cov thev naus laus zis. Kev txhim kho thiab kev siv ntawm cov khoom siv kho qhov muag (Toslink) kev sib txuas ua ke ua ke nrog kev qhia txog CD audio format, qhov twg nws tau siv thawj zaug hauv high-end CD player ua ntej nws nthuav dav hauv tsev ua yeeb yam.
Devices uas tuaj yeem muaj Digital Optical Connections
Kev sib txuas ntawm qhov muag pom feem ntau tshwm sim hauv cov khoom siv hauv qab no:
- DVD player
- Blu-ray Disc player
- Ultra HD Blu-duab tshav Players
- Media streamers
- Cable/satellite boxes
- DVRs
- Game consoles
- CD player
- Home theatre receivers
- Soundbars
- Tsheb stereo receivers
- TVs
SomeBlu-duab tshav players tau tshem tawm digital optical raws li kev sib txuas suab, hloov pauv rau HDMI-tsuas tso zis rau ob qho tib si suab thiab yees duab. Yog tias koj muaj lub tsev ua yeeb yam hauv tsev nrog cov kev sib txuas kho qhov muag tab sis tsis muaj HDMI kev sib txuas, xyuas kom tseeb tias cov cuab yeej koj xav siv suav nrog cov khoom siv kho qhov muag digital.
Digital optical txuas tsuas yog xa suab. Rau kev yees duab, koj yuav tsum tau siv ib hom kev sib txuas, xws li HDMI, tivthaiv, lossis sib xyaw.
Digital Optical Connections thiab Audio Formats
Cov hom digital audio signals uas tuaj yeem hloov pauv los ntawm kev sib txuas digital optical suav nrog ob-channel tso suab PCM, Dolby Digital / Dolby Digital EX, DTS Digital Surround, thiab DTS ES ib puag ncig suab hom.
Qhov kev sib txuas digital optical tau tsim los ua kom haum rau cov qauv suab digital ntawm nws lub sijhawm (feem ntau yog 2-channel CD playback). Yog li, 5.1/7.1 multi-channel PCM, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, DTS: X, thiab Auro 3D Suab cov suab digital tsis tuaj yeem hloov pauv los ntawm kev sib txuas digital optical. Cov hom suab teeb liab hom no yuav tsum tau siv cov kev sib txuas ntawm HDMI.
Digital Optical vs Digital Coaxial Connections
Digital coaxial yog lwm qhov kev sib txuas suab digital nrog cov kev qhia tshwj xeeb thiab cov kev txwv ib yam li digital optical. Txawm li cas los xij, siv RCA-style connectors es tsis txhob siv lub teeb los hloov cov suab paj nruag, cov ntaub ntawv txav ntawm ib txwm xaim.
Qhov sib txawv loj ntawm coaxial thiab optical cables yog tias yav dhau los muaj ntau dua bandwidth. Kev sib txuas coaxial kuj muaj zog dua, tab sis lawv muaj feem cuam tshuam rau electromagnetic cuam tshuam.
