1394 interface, IEEE1394 tsheb npav yog lub siab - tsheb npav ceev, tseem hu ua "FireWire", uas txhawb nqa kub ntsaws, tiag - lub sijhawm xa cov ntaub ntawv, cov qauv tsheb npav, ntsaws thiab ua si. Nws yog siv los txuas cov khoom siv digital nrog cov khoos phis tawj thiab lwm lub tshuab. Nws yog dav siv nyob rau hauv industrial teb. Cov txheej txheem thiab coding txoj kev yog zoo heev, thiab kev sib kis ceev yog ruaj khov. Qhov siab tshaj plaws kis tau tus mob ceev ntawm 1394a yog 400Mbps, thiab qhov siab tshaj plaws kis tau tus mob ceev ntawm 1394b yog 800Mbps, xws li 3.2Gb, tab sis nws yog ib tug kuj tsis tshua muaj thiab tus interface nkag mus yog tsawg. Nws tau monopolized los ntawm Apple thaum ntxov, thiab lub khoos phis tawj feem ntau tsis muaj nws qhov cuam tshuam, yog li xav tau cov npav ntxiv ntxiv. Yuav tsum tau them sai sai rau nws PacketSize cov ntaub ntawv pob ntawv qhov loj me. Packet Size yog bandwidth ntawm tag nrho cov npav 1394. Nrog tsawg CPU cov peev txheej, ntau chav nyob tuaj yeem siv tib lub sijhawm, tab sis vim tias qhov nkag mus rau qhov sib cuam tshuam tsawg, nws tau maj mam tshem tawm los ntawm kev ua lag luam. 1394 interface muab faib ua 4 cores thiab 6 cores. Muaj ob khub ntawm cov ntaub ntawv kab hauv 4 cores, thiab 6 cores tsis suav nrog cov ntaub ntawv. Nws kuj tseem suav nrog cov kab hluav taws xob los muab lub zog rau cov khoom siv sab nraud. IEEE 1394 interface tsis tas yuav muaj tus maub los thiab tuaj yeem paub cov phooj ywg-rau- sib kis. Qhov siab tshaj plaws kis tau tus mob ntawm 1394a yog 4.5 meters, thiab kis tau tus mob nrug ntawm 1394b feem ntau yog 10 meters. Nws tuaj yeem txuas mus rau 100 meters (100Mbps) thaum cov ntaub ntawv tus nqi txo. Cov khoom siv relay yog siv. Kev them nyiaj yug tuaj yeem ua kom qhov sib kis tau zoo ntxiv.
