Tshawb nrhiav qib siab XR thiab tshaj tawm studio coj cov tshuaj ntsuam hom. Kawm paub yuav ua li cas cov hom tshwj xeeb ntawm cov coj zaub xa tawm tiag tiag - lub sijhawm pom kev rau kev ua yeeb yaj kiab virtual.

XR thiab Broadcast Studio LED Screen Hom

Cov kev lag luam ua yeeb yaj kiab thiab kev tshaj tawm hauv xov tooj cua tau dhau los ua qhov hloov pauv loj hauv lawv li cas lawv tsim ib puag ncig yav dhau los. Cov ntxaij vab tshaus ntsuab ib txwm muaj, uas yuav tsum muaj kev tshaj tawm dav dav - kev tsim khoom sib xyaw, tau nce ntxiv los ntawm Extended Reality (XR) ntim. Nkag siab cov kev tshwj xeeb noLED npo homyog qhov tseem ceeb rau studio engineers thiab cov thawj tswj kev tsim khoom uas xav sync lub koob yees duab nyob nrog lub sijhawm tiag tiag -ib puag ncig digital.

Txhais XR thiab tshaj tawm hom ntawm LED zaub

Ib qho XR ntim yog qhov chaw ua yeeb yaj kiab lub cev uas nyob nrog siab -kev ua tau zoo LED vaj huam sib luag. Cov kab ke no feem ntau suav nrog cov duab nkhaus ntsug thiab qhov sib tham sib LED pem teb. Lub hom phiaj tseem ceeb ntawm engineering thaum tsim cov nohom coj zaubcov qauv yog kom phim cov kev xav tau sai ntawm cov koob yees duab xinesmas.

Tsis zoo li cov qauv kev lag luam, cov xov xwm tshaj tawm suav nrog siab - kawg tsav ICs (Integrated Circuits, cov microchips uas tswj xyuas lub zog ntws mus rau ib tus pixel diodes) los tswj cov xim qhov tob thiab thav duab synchronization. Cov khoom no xyuas kom meej tias cov kev hloov tshiab hauv keeb kwm yav dhau ntawm lub sijhawm millisecond lub koob yees duab shutter qhib.

Common Application Scenes rau Virtual Production

Zaj duab xis Studios thiab Virtual Production theem

Hauv kev tsim yeeb yaj kiab, cov thawj coj siv cov kev tshwj xeeb nohom LED zaub screenphab ntsa los ua kom muaj tseeb 3D ib puag ncig, xws li cov neeg txawv teb chaws toj roob hauv pes lossis hauv nroog txoj kev, tom qab cov neeg ua yeeb yam. Vim tias lub vijtsam emits lub teeb tiag tiag, nws ib txwm ua kom pom cov neeg ua yeeb yam thiab cov khoom siv ntawm theem, tshem tawm cov kev xav ntsuab tsis muaj tseeb uas tshwm sim nrog cov qub qub chroma- teeb tsa tseem ceeb.

Tshaj tawm hauv TV thiab koom nrog cov xwm txheej

Cov xov xwm hauv xov tooj cua, xov xwm kis las, thiab kev tshaj tawm cov khoom lag luam loj tau txais cov kev tshaj lij nohom LED zaublos tsim dynamic virtual sets. Cov neeg tshaj tawm tuaj yeem sawv hauv lub studio thiab sib cuam tshuam nrog tiag tiag - lub sijhawm cov ntaub ntawv kab kos lossis 3D cov yeeb yaj kiab uas tshwm sim nyob ib puag ncig lawv, txhim kho qhov pom kev pom rau cov neeg saib nyob deb.

Kev sib txawv thiab cov ntsiab lus tseem ceeb

Thaum qhia txog XR- ntsuashom coj screenconfigurations, engineers yuav tsum tau saib yav dhau los cov zauv daws teeb meem thiab ntsuam xyuas lub koob yees duab compatibility metrics.

Scan Rate thiab Refresh Frequency:Kev tshaj tawm cov ntxaij vab tshaus feem ntau siv qhov ntsuas qis qis (qhov sib faib feem ntawm cov kab pixel ntau npaum li cas tau tsav los ntawm ib kab hluav taws xob ib leeg) thiab ua kom muaj zog dua 7,680Hz. Qhov kev tsim no tiv thaiv cov kab dub dov scan tsis tshwm sim ntawm cov yeeb yaj kiab kaw.

Xim Space thiab Gamut:Virtual ntau lawm yuav tsum tau muab cov xim luam tawm meej. High-end XR panels txhawb cov xim gamuts, xws li DCI-P3 (ib qho xim xim qhov chaw uas feem ntau siv hauv cov yeeb yaj kiab digital projection), kom ntseeg tau tias cov xim backdrop zoo phim cov khoom siv hauv lub cev.

Moire Pattern Mitigation:Thaum lub koob yees duab tsom rau ntawm lub vaj huam sib luag LED, ib qho kev cuam tshuam kho qhov muag hu ua moire qauv tuaj yeem tshwm sim. Kev txo cov nyhuv no yuav tsum xaiv qhov zoo pixel suab lossis kho lub diode nto nrog optical diffusion txheej.

Qhov zoo ntawm XR Media Ib puag ncig

Kev siv cov khoom siv tsim khoom siv virtual ua kom pom tseeb ua haujlwm zoo rau lub studio muaj tswv yim. Nws tso cai rau cov neeg ua yeeb yam pom lawv qhov chaw nyob ib puag ncig tsis yog ntsia ntawm phab ntsa ntsuab dawb, uas tuaj yeem txhim kho kev ua tau zoo thiab kev paub txog qhov chaw thaum ua yeeb yaj kiab.

Tsis tas li ntawd, vim hais tias ib puag ncig yav dhau los raug kho thiab ua tiav thaum lub sijhawm tua, cov tuam txhab tsim khoom tuaj yeem txo lub sijhawm thiab nyiaj txiag siv rau kev tshaj tawm - tsim cov teebmeem pom. Tus ncej siab- tus nqi peev xwm kuj txhawb cov txheej txheem siab heev xws li ntau- lub koob yees duab taug qab, qhov twg ib qho screen qhia txawv keeb kwm yav dhau los cais lub koob yees duab ib txhij.

Cov ntsiab lus thiab cov lus pom zoo

Rau cov theem ua yeeb yaj kiab tshaj lij, TV studios, thiab qhov chaw zoo tshaj plaws virtual, kev nqis peev hauv XR-cov qauv ntawv pov thawj yog qhov tsim nyog kom ua tiav kev tshaj tawm - cov txiaj ntsig zoo. Thaum tsim koj lub ntim, xyuas kom meej tias koj lub koob yees duab taug qab qhov system, media servers, thiab LED processors siv tib yam genlock (cov txheej txheem synchronization uas ua kom txhua yam khoom siv yees duab ua haujlwm ntawm tib lub sijhawm pulse) cov cim.

Nws raug nquahu kom ua qhov ntsuas lub koob yees duab nrog koj qhov kev teeb tsa lub lens tshwj xeeb ua ntej kev teeb tsa kom paub meej tias moire artifacts tseem nyob hauv qhov kam rau ua.

Cov lus nug nquag

XR coj screen hom twg yuav tsum tau rau studio ceilings?

Studio ceilings feem ntau siv siab - tso zis, dav - suab LED vaj huam sib luag hu ua skylights. Cov vaj huam sib luag no tau tsim ua feem ntau los muab qhov tseeb ib puag ncig teeb pom kev zoo thiab muag muag ambient reflections rau cov neeg ua yeeb yam hauv qab no, tsis yog siab - daws teeb meem.

Vim li cas cov qauv ntawm cov coj zaub flicker thaum saib los ntawm lub koob yees duab?

Flicker tshwm sim thaum qhov screen qhov refresh npaum li cas tsis phim lub koob yees duab shutter ceev. Tshaj tawm- qib cov ntxaij vab tshaus siv ultra- siab refresh zaus kom ntseeg tau tias lub voj voog diodes ceev txaus kom tsis pom lub koob yees duab sensors.

Lub peev xwm thauj khoom siab tshaj plaws rau pem teb yog dab tsi -raws li hom coj zaub screen?

Thaum qhov hnyav sib txawv los ntawm tus qauv, hnyav -cov haujlwm sib tham sib hauv pem teb feem ntau yog tsim los txhawb ntau pua kilograms ib square meter. Qhov kev tsim vaj tsev no tso cai rau lawv los tuav cov koob yees duab studio hnyav, taug qab cov cranes, thiab cov tswv cuab tsis tau tawg.

Puas yog XR hom coj zaub txhawb nqa HDR cov ntsiab lus?

Yog lawm, feem ntau cov khoom siv virtual yog tsim los txhawb High Dynamic Range (HDR) cov qauv, tso cai rau lawv khaws cov duab ntxoov ntxoo zoo thiab cov ntsiab lus ci hauv tib lub thav duab.

Yuav ua li cas sib txawv ntawm LED screen kov taug qab sensors?

XR cov ntxaij vab tshaus tshwj xeeb feem ntau suav nrog cov ntsiab lus txuas lossis infrared- cov cim cuam tshuam ncaj qha rau hauv lawv cov thav duab, tso cai rau lub koob yees duab taug qab cov tshuab ua kom pom qhov chaw ntawm lub cev hauv lub sijhawm.
