Yuav ua li cas thiaj paub qhov loj ntawm qhov sib txuas ntawm lub PCI Express Capture Card

Lub PCI-E interface ntawm lub capture card yog qhov ua rau koj muaj bandwidth ntau npaum li cas

PCI Express yog ib qhov tseem ceeb tshaj plaws uas cuag sib txawv rau bandwidth efficiency ntawm ib lub capture card. Capture card tuaj yeem hloov kho lwm yam hauv kompyuta, piv txwv li CPU, kev ua haujlwm ntawm memory, siv PCI Express lanes (fast path). Bandwidth ntawm PCI Express interface qhia cov bit rate uas tawm los ntawm IO device loss memory, tab sis, lub nruab ntawm lanes hauv PCI express interface qhia tus nqi ntawm cov ntaub ntawv uas yooj zoo li transfer nyob rau hauv ib lub sijhawm. Piv txwv li, ib lub PCI Express capture card uas muaj 16-lane interface yuav muaj bandwidth efficiency siab dua li ib lub card uas muaj 8-lane interface vim nws tuaj yeem txav cov ntaub ntawv ntau dua ib zaug.

Cov ncauj lus uas cuag sib txawv rau data transfer speed ntawm PCIE capture card

Ib co ncauj lus cuag sib txawv rau speed uas koj tuaj yeem txav cov ntaub ntawv nyob rau hauv PCI Express pci e video capture card . Qhov chaw tshwm sim dua yog qhov kev sib cuag PAC rau qhov kev hloov pauv ntau. Piv txwv li, kev hloov pauv ntev dua ntawm PCI Express, piv txwv li PCI Express 3.0 lossis PCI 4.0, muaj peev xwm hloov kho dua li qhov kev hloov pauv ntxiv. Txawm li ntawd, qhov nta khawm nrog qhov interface generation tshiab dua yuav muaj peev xwm hloov kho siab dua thiab nrog kev sib tham ntau dua.

Qhov kev kawm txog bus ntev/pauv rau kev hloov kho siab

Kev hloov kho ntawm a pci e capture card tseem nyob ntawm nws bus ntev. Bus Width Bus ntev qhia qhov ntau ntawm cov khawm sib txuas hauv PCI Express interface uas tuaj yeem tiv tauv lossis paub txog cov ntaub ntawv hauv ib lub sijhawm. Thiab rau qhov nta khawm nrog dav dav, hloov kho ntau dua hauv ib lub sijhawm, nws muaj kev hloov kho siab dua. Lwm yam, qhov dav dav nrog PCI Express interface generation tshiab dua tuaj yeem pab tiv thaiv kev hloov kho ntawm qhov nta khawm, thiab kho cov ntaub ntawv ntau dua nrog kev nplij siab.

Yuav li cas li sib txawv hom ntawm kev cim nrog qhov loj ntawm qhov chaw cim li ua rau PCI Express Capture Card

Tab sis nyob rau sab nraud ntawm pci express capture card bus interface, peb kuj tseem yuav tsum xav seb hom kev cim thiab qhov loj ntawm nws uas capture card siv los ua rau nws qhov siab thiab qhov siab ntawm kev siv kho vajtswm. Kev cim yog ib yam uas tseem ceeb rau kev cim kho thiab kev hloov pauv ntawm cov ntaub ntawv uas raug sib kis los ntawm capture card. Capture card uas muaj ntau kev cim ntau dua yuav tseg tau ntau ntaub ntawv hauv ib zog rau kev ua haujlwm zoo thiab siab. Tom qab ntawd, kev siv cov hom kev cim zoo thiab siab (DDR4, GDDR6 thiab lwm yam) kuj tuaj yeem pab rau kev ua haujlwm zoo thiab qhov bandwidth efficiency ntawm capture card.
