Lub bandwidth yuav tsum muaj cov koob yees duab muaj nyob ntawm lub koob yees duab kev daws teeb meem, tus ncej, thiab cov nyom ntawm cov duab duab. Rau kev ua kom zoo thiab ceev cov duab kuaj pom kev ua haujlwm, kab ntawm lub txuas yuav tsum tau loj txaus kom tsis txhob muaj cov ntaub ntawv poob lossis xa cov ntaub ntawv qeeb. Nov yog ob peb yam tseem ceeb los pab txiav txim siab ntau npaum li cas bandwidth xav tau:
- Kev daws teeb meem: Qhov siab dua cov duab daws teeb meem, qhov loj dua cov ntaub ntawv cov duab ib tus duab. Piv txwv li, cov duab duab ntawm 1K daws teeb meem yog qhov me dua li ntawm 4K daws teeb meem. Rau cov koob yees duab kev daws teeb meem siab (xws li 4k, 8k), lub bandwidth yuav tsum nce ntxiv.
- Tus ncej: Qhov ntau dua tus ncej, cov duab ntau dua yog kis ib ob, uas tseem yuav nce bandwidth. Kev kub ceev cov koob yees duab feem ntau yuav tsum tau xa ib txhiab xyoo rau ib ob (FPS), yog li lawv bandwidth tej kev xav tau.
- Hom duab hom: yog tias lub koob yees duab tau txais cov duab xim, tus nqi ntawm ib pixel yog qhov loj dua tias ntawm grayscale cov duab. Ib qho ntxiv, txawm hais tias ib qho qauv compressed (xws li JPEG, H.264, thiab lwm yam) yog siv kuj tseem yuav cuam tshuam rau kev xa mus rau cov kev lis haujlwm. Compressed cov duab yuav tsum muaj cov duab tsawg dua, thaum tsis pom cov duab (xws li cov qauv raw) yuav tsum tau bandwidth ntau dua.
Bandwidth yuav tsum muaj cov sib txuas ua ke:
- Lub zeem muag gige: feem ntau siv rau cov ntawv thov uas muaj qhov tsawg rau nruab nrab bandwidth, thiab yog qhov tsim nyog rau cov ntawv thov daws teeb meem tsawg dua lossis tus lej qis. Rau cov ntawv thov nrog siab dua lossis tus lej lej, ntau lub gbps daws teeb meem thiab cov ntawv pom zoo nrog kev daws teeb meem nruab nrab, xws li kev lag luam kev lag luam, kev soj ntsuam, thiab lwm yam. Tej zaum nws yuav muaj me ntsis tsis txaus rau cov ntawv thov nrog bandwidth ntau dua (xws li cov duab siab tiag tiag).
- Lub koob yees duab txuas: Txhawb Bandwidths los ntawm 2 Gbps rau 6.25 Gbps, haum rau cov haujlwm zoo, haum siv tshuab ceev ceev tshuab muag lossis tshuaj xyuas zoo.
- Coaxpress: Txhawb Nqa Ib Leeg-channel bandwidth txog 6.25 Gbps, thiab cov txheej txheem muaj kev sib xyaw ua ke, xws li cov kab kev lag luam muaj kev sib xyaw ua kom zoo nkauj.
Yuav ua li cas xaiv bandwidth?
Thaum xaiv bandwidth, koj tuaj yeem txiav txim siab nws raws li cov ntsiab lus hauv qab no:
- Lub koob yees duab daws teeb meem: qhov siab dua cov kev daws teeb meem, ntau dua rau cov bandwidth yuav tsum tau.
- Tus ncej yuav tsum tau ua: High-ceev cov duab kuaj cov tshuab yuav tsum tau bandwidth.
- Cov ntaub ntawv sib kis hom: Yog tias cov duab duab tsis tau compressed lossis siab-precision cov duab yuav tsum tau ua, bandwidth tej yam yuav muaj siab dua.
- Piv txwv li Scenarios: piv txwv li cov kab ntau yam yuav tsum tau latency thiab high bandwidth, thaum kev soj ntsuam kev ruaj ntseg tuaj yeem tiv thaiv bandwidth.
Hauv ntej, cov kab ke bandwidth nyob ntawm seb cov duab uas tau txais yuav tsum tau ua. Xaiv lub choj txuas tuaj yeem ua kom pom tseeb cov duab du thiab kom tsis txhob muaj ntim lossis cov ntaub ntawv poob.
