Nkag siab lub luag haujlwm ntawm cov txheej txheem ua yeeb yaj kiab thiab xa daim npav hauv kev tswj hwm theem coj lub vijtsam kom du, lag- pub dawb nyob hauv video playback.
Qhia rau theem LED Screen Control Systems thiab Processors
Qhov pom kev zoo ntawm atheem coj screennyob ntawm ntau dua li cov pixel panels; nws vam khom ntau ntawm cov khoom siv kho vajtse backend. Lub siab -kev ua tau zoo video processor txhais cov xov xwm hauv lub teeb liab uas LED phab ntsa tuaj yeem tso saib yam tsis muaj latency lossis xim txawv. Phau ntawv qhia no piav qhia txog cov ntsiab lus tseem ceeb ntawm kev tswj hwm tom qab ib qho kev tshwm sim video phab ntsa.
Kev ua haujlwm ntawm LED Control System
Ibcoj theem screentsis tuaj yeem txuas ncaj qha rau hauv lub computer tus qauv HDMI chaw nres nkoj zoo li lub monitor hauv tsev. Nws yuav tsum tau muaj kev tswj hwm ecosystem los qhia cov teeb liab video kom raug.
Cov ntaub ntawv xov xwm xa cov ntaub ntawv nyoos video mus rau video processor. Cov txheej txheem ntsuas, qoob loo, thiab kho cov duab ua ntej xa mus rau lub thawv xa khoom. Lub thawv xa khoom hloov cov yees duab mus rau hauv cov ntaub ntawv tshwj xeeb, uas taug kev los ntawm kev sib txuas hauv network mus rau tus neeg tau txais daim npav nyob hauv txhua lub txee ntawm lubcoj screen ntawm theem.
Lub luag haujlwm tseem ceeb ntawm theem Video Processor
Tus kws tshaj lij video processor yog lub hauv paus rau txhua qhov kev pom pom thaum lub sijhawm ua haujlwm nyob, ua ntau yam haujlwm tseem ceeb.
| Muaj nuj nqi | Kev piav qhia | Kev lag luam tseem ceeb |
| Splicing & Scaling | Resizes video inputs kom haum raws li kev cai daws teeb meem ntawm LED phab ntsa. | Tiv thaiv kom tsis txhob ncab lossis sau ntawv ntawm kev nthuav qhia slides. |
| Multi-Signal Switching | Smoothly switches ntawm txawv lub koob yees duab nyob thiab computers. | Ua kom muaj kev hloov pauv tsis sib haum yam tsis muaj cov ntxaij vab tshaus dub thaum lub sijhawm ua yeeb yam. |
| PIP (Duab-hauv-Daim duab) | Overlays ib lub qhov rais video nyob rau sab saum toj ntawm lwm lub qhov rais tom qab. | Tso cai rau kev nthuav qhia cov slides nyob ib sab ntawm lub koob yees duab noj. |
| Tsawg Latency Processing | Minimizes qhov ncua sij hawm ntawm qhov kev ua si nyob thiab qhov screen zaub. | Qhov tseem ceeb rau khaws suab hauv sync nrog IMAG sab qhia. |
Kev xa thiab txais daim npav piav qhia
Internal ntaub ntawv txhais lus yog tswj los ntawm ob lub ntsiab Cheebtsam nyob rau hauv lubtheem coj zaubecosystem.
Xa Daim Npav / Box
Nyob ze ntawm lub khoos phis tawj tswj hwm, cov khoom siv no siv lub teeb liab video los ntawm lub processor thiab faib nws hla ntau Ethernet outputs. Txhua qhov tso zis cable feem ntau tuaj yeem tsav qhov tshwj xeeb tshaj plaws ntawm pixels (feem ntau nyob ib puag ncig 650,000 pixels ntawm tus qauv 60Hz refresh npaum li cas), xav tau cov kws tshaj lij los qhia cov ntaub ntawv taug kev kom zoo.
Daim Npav Txais
Txhua tus neeg txee hauv ibtheem screen cojteeb muaj ib daim npav txais. Daim npav no lees txais cov ntaub ntawv ntws los ntawm lub thawv xa khoom thiab qhia txhua qhov SMD LED pixel ntawm lub vaj huam sib luag tshwj xeeb raws li qhov xim thiab qhov ci ci kom pom hauv lub sijhawm tiag tiag -.
Xaiv Tus Tswj Txoj Cai rau Live Staging
Rau kev nyob ib puag ncig, kev tswj hwm yuav tsum suav nrog cov yam ntxwv tshwj xeeb ntawm kev ntseeg tau:
EDID Management:EDID (Extended Display Identification Data, ib tug kos npe digital uas qhia lub computer seb qhov kev daws teeb meem ntawm lub vijtsam txhawb nqa dab tsi) kev tswj xyuas kom lub khoos phis tawj tswj tau qhov kev daws teeb meem tiag tiag uas yuav tsum tau ua los ntawmcoj screen theem.
Frame Synchronization:Genlock (Generator Lock, txheej txheem uas synchronizes video ncej tus nqi ntawm ntau yam khoom siv) synchronization tiv thaiv "screen tearing," qhov chaw sib txawv ntawm cov phab ntsa loj video tso tawm me ntsis offset video thav ntawv thaum lub sijhawm nrawm.
Cov ntsiab lus thiab cov lus pom zoo
Thaum qhia txog atheem coj screensystem, tsis txhob overlook lub txheej txheem hardware. Rau kev tshaj tawm hauv xov xwm thiab IMAG, xyuas kom koj cov video processor txhawb qis -latency hom thiab Genlock synchronization. Ib txwm npaj koj cov ntaub ntawv xaim layout kom tsis txhob muaj ib lub network cable tshaj nws qhov siab tshaj plaws pixel peev xwm, ua kom muaj kev ruaj khov, glitch- tsis pub pom kev ua haujlwm.
Cov lus nug nquag
Genlock yog dab tsi, thiab vim li cas nws thiaj li xav tau rau lub vijtsam coj ntawm theem?
Genlock synchronizes lub voj voog tshiab ntawm cov video processor nrog cov koob yees duab tshaj tawm. Yog tsis muaj nws, lub koob yees duab yuav ntes tau ib tug sib cais-frame artifact hu ua "tearing" thaum filming ceev- txav cov ntsiab lus ntawm lubcoj theem screen.
Muaj pes tsawg pixels tau tus qauv Gigabit network cable tsav ntawm lub vijtsam coj theem?
Raws li cov txheej txheem ntawm 60Hz refresh npaum li cas nrog 8-ntsis xim, ib lub network cable los ntawm ib daim npav xa tuaj yeem tsav mus txog 650,000 pixels ua ntej yuav tsum tau siv cov ntaub ntawv thib ob.
Yuav ua li cas yog tias ib daim npav txais tsis tau nyob rau hauv theem screen coj txee?
Yog tias daim npav txais ua tsis tiav, lub txee tshwj xeeb ntawd-thiab tej zaum yuav muaj cov txee tom ntej daisy- chained downstream los ntawm nws-yuav plam teeb liab thiab dub, tshwj tsis yog tias cov ntaub ntawv thaub qab rov qab ua haujlwm.
