HDMI (High Definition Multimedia Interface) thiab SDI (Serial Digital Interface) yog ob qhov sib txawv digital video interface qauv, txhua tus muaj cov yam ntxwv tshwj xeeb thiab daim ntawv thov. Kab lus no yuav muab cov ncauj lus kom ntxaws sib piv ntawm ob lub interfaces no.
Ib, Transmission method
HDMI:
1. Kev siv cov teeb liab sib txuas ua ke.
2. Siv 19 tus pin interface, lub suab thiab cov teeb liab tuaj yeem sib kis tau ib txhij.
3. Txhawb ntau qhov kev daws teeb meem, suav nrog 4K, 8K, thiab lwm yam kev daws teeb meem siab.
4. Txhawb HDCP encryption tiv thaiv tus cwj pwm tsis raug cai.
5. Qhov kev ncua deb ntawm kev sib kis feem ntau yog luv, feem ntau nyob rau hauv 30 meters, thiab dhau qhov kev ncua deb, yuav tsum muaj lub teeb liab amplifier lossis converter.
SDI:
1. Kev siv serial teeb liab kis tau tus mob txoj kev, uas yog, lub teeb liab kis tau los ntawm me ntsis.
2. Siv BNC interface, feem ntau tsuas yog cov teeb liab video raug xa mus (txawm tias qee cov qauv txhawb nqa lub suab).
3. Txhawb kev daws teeb meem sib txawv, los ntawm Standard Definition (SD) mus rau High Definition (HD) thiab tom qab ntawd mus rau Ultra High Definition (UHD).
4. Qhov kev sib kis tau ntev ntev, txog li 100 meters lossis ntau dua, thiab tuaj yeem txuas ntxiv los ntawm cov khoom siv hluav taws xob cable.
2, Daim ntawv thov scenarios
HDMI:
1. Feem ntau yog siv rau pej xeem lub hom phiaj, xws li kev lom zem hauv tsev, lub computer saib, game consoles, thiab lwm yam.
2. Siv dav hauv cov khoom siv hluav taws xob siv hluav taws xob nrog cov neeg siv khoom zoo.
SDI:
1. Feem ntau yog siv rau hauv kev tshaj tawm kev tshaj tawm thiab kev tsim yeeb yaj kiab.
2. Haum rau daim ntawv thov scenarios uas yuav tsum tau ntev - kis tau tus mob nyob deb, siab tiag tiag - lub sij hawm ua tau zoo, thiab stability.
3, Nqi
HDMI:
1. Tsawg nqi, tshwj xeeb tshaj yog nyob rau hauv luv luv kis tau tus mob.
2. Tus nqi ntawm HDMI cables thiab interfaces nce nrog ntev.
SDI:
1. Tus nqi qis, tshwj xeeb tshaj yog nyob rau hauv ntev - kis tau tus mob.
4, Compatibility thiab Scalability
HDMI:
1. Nws muaj zoo compatibility thiab scalability, txhawb ntau lub suab tawm tswv yim thiab nta.
2. Nws tuaj yeem txhawb cov kev daws teeb meem siab dua thiab hloov tshiab los ntawm cov qauv tshiab xws li HDMI 2.1.
SDI:
1. Muaj kev sib raug zoo hauv kev tshaj lij, tshwj xeeb tshaj yog rau cov qauv tshaj tawm.
2. SDI systems feem ntau xav tau cov cuab yeej tshwj xeeb thiab cov hloov pauv rau kev nthuav dav lossis kev sib raug zoo nrog lwm cov qauv.
5, Anti- muaj peev xwm cuam tshuam
HDMI:
1. Kev tiv thaiv tsis zoo los tiv thaiv- muaj peev xwm cuam tshuam thiab cuam tshuam rau electromagnetic cuam tshuam.
2. Kev ceev faj yuav tsum tau them kom tsis txhob cuam tshuam nrog lwm cov khoom siv hluav taws xob thaum lub sijhawm teeb tsa.
SDI:
1. Vim yog siv cov coaxial cables, nws muaj zog tiv thaiv - muaj peev xwm cuam tshuam.
2. Tsim nyog rau siv nyob rau hauv complex electromagnetic ib puag ncig.
6, Teeb pom kev zoo
HDMI:
1. Txhawb siab - zoo suab thiab video teeb liab kis tau tus mob.
2. Kev sib kis tau zoo tshaj qhov luv luv.
SDI:
1. Cov teeb liab kis tau tus mob yog uncompressed, haum rau cov kev tshaj lij uas yuav tsum tau siab - video zoo.
2. Vim yog txoj kev sib kis ntawm serial, cov teeb liab zoo nyob ruaj khov nyob rau qhov ntev.
HDMI yog tus qauv siv dav uas tsim nyog rau feem ntau cov ntawv thov pej xeem, txhawb kev sib kis ntawm cov suab thiab video ib txhij ntawm tus nqi qis, tab sis muaj kev txwv nyob rau hauv ntev - kis tau tus mob. SDI yog tus txheej txheem kev tshaj lij feem ntau siv hauv kev tshaj tawm thiab tshaj tawm cov yeeb yaj kiab. Nws txhawb nqa ntev - kis tau tus mob nyob deb, muaj kev ruaj ntseg siab thiab tiv thaiv - muaj peev xwm cuam tshuam, tab sis tsis txhawb kev xa xov suab (tshwj tsis yog siv cov ntawv sau nrog suab).
