High Definition Interface Multimedia Interface (HDMI) yog ib qho digital video / audio interface technology uas yog kev sib koom tes rau cov duab xa duab uas tib lub sij hawm xa cov suab thiab video teeb liab. HDMI yog thawj tsim rau CRT. Cov ntsiab lus video ntawm DVI, HDMI thiab UDI kis tau zoo nyob rau hauv txoj kev ua haujlwm sai thiab siab. Qhov no saib xyuas kom cov kev sib tw hauv lub xov tooj yuav tsis muab thaiv thaum nws loj.
DisplayPort yog tsim los tsim rau cov kev ntsuas LCD. Nws siv "Micro-Packet Architecture" kis duab, thiab cov ntsiab lus yeeb yaj kiab tau xa mus rau hauv ib lub pob ntawv. Qhov no txawv ntawm kev yees duab yees yees duab xws li DVI cable thiab HDMI cable. Nyob rau hauv lwm yam lus, qhov tshwm sim ntawm HDMI cable hloov analog yees duab, thiab qhov tshwm sim ntawm DisplayPort interface hloov DVI thiab VGA interfaces.
Los ntawm lub cev, Lub HDMI cable thiab Displayport cable khiav lag luam ntawm tib lub hom phiaj thiab sib txawv coaxial twisted khub, siv high-speed, tsawg-voltage sib txawv teeb liab mus rau kis cov ntaub ntawv, tab sis ib yam yog qhov tseeb.
Txawm tias ob qhov qauv no zoo sib xws nyob rau hauv tsos, lawv yog cov sib txawv. Cov kev sib txawv no txiav txim siab qhov kev ua tau zoo ntawm qhov txuas thiab nws cov nqi, kev sib tw, kev ua tau zoo, thiab yooj yim ntawm kev ua tiav.
Tus qauv HDMI cable tam sim no qhia txog plaub tus connectors, A rau D. Tsuas yog hom B, tus so yog 19 pins. Hom C thiab D yog rau cov ntawv siv tau thiab cov ntawv me me. Cov cab siv hauv ob qhov qauv yog txawv me ntsis.
HDMI cable 1.0 version rau 1.3 version siv 4 shielded coaxial txawv officers, 4 ib txhiab tswj tseg, hluav taws xob mov (+ 5V) thiab hauv av. Tus 1.4 HDMI cable ntxiv ib lub suab xa rov qab thiab ib qho Ethernet channel, yog li ntawd qhov teeb meem ntawm kev tsim duab. HDMI 1.4 siv 4 coaxial officers, 1 khawm sib npaug, 3 teeb tseg ib zaug, fais fab tuag (+ 5V), thiab av.
Qhov no txhais tau hais tias 1.4 lub xov tooj HDMI cable thiab 1.3 cable HDMI cable siv ntau cov cables. Yog hais tias tus kab mob tsis yog HDMI 1.4 siv nyob rau hauv HDMI 1.4, lub suab yuav rov qab nqa thiab Ethernet kev ua haujlwm yuav poob. Txawm li cas los, tag nrho cov nta HDMI 1.3 thiab lwm yam tshiab nta ntawm HDMI 1.4 (xws li 3D) yuav khaws cia.
DisplayPort txhais ob lub nruas, Puv Ntev thiab Mini. Ob lub connectors muaj 20 pins, tab sis qhov dav ntawm lub mini connectors yog kwv yees li ib nrab ntawm tag nrho cov loj, thiab lawv yog 7.5 hli x 4.5 hli thiab 16 hli x 4.8 hli, feem. Lub tuam tsev ua tiav tag nrho yuav tsum muaj tsib lub koomhaum ua ke, peb cov cim tseg ib zaug, thiab lub zog thiab hauv av.
Lub scalability ntawm DisplayPort nws tus kheej pub rau cov creation ntawm qis-bandwidth DisplayPort mus nrog cov xov hlau, tab sis ob peb ua li ntawd vim nws muaj peev xwm ua rau cov teeb meem daws teeb meem rau cov neeg siv xaus.
