Nrog rau kev loj hlob sai ntawm network thiab codec thev naus laus zis, txhawm rau ua kom tau raws li qhov chaw hais kom ua, cov ntaub ntawv chaw thiab lwm cov kev daws teeb meem loj hauv suab thiab video.
Qhov kev thov ntawm kev daws teeb meem kev sib txuas, kev faib tawm tshwm sim.
LED muaj qhov zoo tshaj plaws vim nws txoj hlua khi tsis sib haum, hloov pauv qhov loj me, thiab cov xim zoo nkauj hauv cov ntawv xa tawm.
Yog li vim li cas cov kab ke faib tawm ib txwm muaj yuav tshwm sim cov teeb meem no, thiab Nova [saum ntuj ceeb tsheej lub zog faib hluav taws xob] los ntawm kev siv zog dab tsi, kom ua tiav kev ua si rau cov khoom zoo ntawm LED, kom ua tiav qhov kev nkag siab tshaj plaws ntawm LED faib.
Ib txwm faib qhov system
Tam sim no, cov kev faib tawm nrov hauv kev ua lag luam feem ntau yog siv tus qauv H264 / H265 sib sib zog nqus compression algorithm los txhawm rau thawj HD video teeb liab rau hauv txoj kev teeb liab.Txawm hais tias lub siab compression piv zoo heev txo qhov yuav tsum tau ntawm kev sib kis bandwidth, qhov tsis zoo kuj tseem pom tseeb heev.
Qhov tsis zoo: ①: Tsis zoo compression ua rau cov duab loj tsis zoo
Lub compression piv ntawm tus qauv sib sib zog nqus compression algorithm tuaj yeem ncav cuag 50-300 zaug, thiab qhov sib piv siab compression yuav tsum coj cov duab tsis zoo.Kev faib tawm ib txwm tsuas yog txhawb nqa 8bi t 4: 2 ∶ 0 kev ua haujlwm, ua rau cov xim tsis txaus ntawm tag nrho cov kev faib tawm, tshwj xeeb tshaj yog nyob rau hauv cov ntawv nyeem cov duab thiab cov xim sib txawv, rau cov zaub
Qhov tsis zoo.②:qhia qhov loj latency
H.264/H.265 Lub inter thav duab compression algorithm qhia txog kev ncua sijhawm ntawm 2-3 thav ntawv hauv ob qho tib si kev txiav txim siab thiab kev nkag.Ntxiv nrog rau kev cuam tshuam ntawm kev sib kis raws tu qauv, kev ua duab thiab lwm qhov chaw, kev ncua sijhawm ntawm qee cov khoom txawm tias tshaj 120ms, thiab muaj qhov pom tseeb qeeb thiab lag kev xav, uas ua rau cov neeg siv kev ua haujlwm tau zoo.
Disadvantages ③: splicing loj screen synchronization tsis zoo, muaj zog tsim kua muag
Cov tsoos faib synchronization raug yog tsawg, qhov sib txawv ntawm qhov sib txawv feem ntau nyob ntawm ntau pua ntawm peb lossis txawm tias qib ms, thiab lub xeev synchronization tsis ruaj khov txaus, uas ua rau lub vijtsam tsis meej yuav yog.
Lub tearing tshwm sim, tsis tsuas yog pom ntawm qhov muag liab qab, tab sis pom tseeb dua thaum thaij duab, cuam tshuam rau cov duab ntawm LED screen.
Qhov tsis zoo ④: Tsuas yog cov qauv daws teeb meem nkaus xwb
Vim nws cov yam ntxwv modular thiab arbitrary splicing, LED feem ntau muaj ntau yam tshwj xeeb uas tsis yog-tus qauv daws teeb meem.Thiab cov tsoos faib zaub feem ntau yog siv hauv cov kua siv lead ua kua
Ntawm no, tsuas yog txhawb nqa cov qauv kev daws teeb meem ib txwm muaj, xws li 1920 * 1080,2048 * 1536, lawv tsis muaj phooj ywg txaus los txhawb rau qhov tshwj xeeb thiab hloov pauv ntawm LED.Hauv kev ua
Tej zaum yuav muaj qhov sib txawv ntawm qhov sib txawv thiab lwm yam kev mob, thiab txawm tias xav tau ntau yam splicing, uas tsis tsuas yog nce tus nqi ntawm cov neeg siv khoom, tab sis kuj tseem cuam tshuam rau cov neeg siv kev paub.
[Tianquan Distributed System] txais HEVC Plus compression algorithm, ua ke nrog 10bit 4 ∶ 4, tag nrho txuas 4K @ 60Hz, nanosecond synchronization, thiab tso saib los ntawm
Txhais thiab lwm yam kev ua tiav, tuav qis bandwidth thaum khaws cov ntsiab lus ntxiv, los ntawm cov duab zoo, synchronization, ncua thiab so kuaj, smoothness thiab lwm qhov ntev, xa tag nrho
Swing tawm cov zaub kom zoo dua ntawm LED.
10-ntsis 4: 4: 4 haiv duab zoo yog lifelike
Nova NSMC ntse duab encoding thev naus laus zis, ua ke nrog lub platform tshwj xeeb kho vajtse, ua kom haum rau HFR codec, tuaj yeem txhawb nqa txog 120Hz refresh npaum li cas,Capture thiab tso saib ntawm high-ceev video yog clearer.Nyob rau tib lub sijhawm, NSMC txhawb nqa 10-ntsis 4: 4 kev ua haujlwm, hais txog Kev Tshawb Pom Ntse, los ntawm kev pom lub computer.
Kev txheeb xyuas, kev sib piv histogram thiab ntug kev lees paub algorithm, kev txawj ntse sib txawv ntawm qhov xwm txheej thiab cov ntawv nyeem, kev hloov kho ntawm codec algorithm, nrog rab koob
Kev sib deev duab compression, decompression, kom cov xim txo qis dua qhov tseeb thiab raug, cov nplai grey maj mam hloov thiab du, pab txhawb BT2020, tiag tiag nrogLED zaubnta, kom ua tiav HDR.
Ib txwm ua cov lus
NMSC cov lus ua tiav
Tom qab Nova NSMC ntse duab coding tshuab ua cov ntawv nyeem: chroma cov ntaub ntawv tseem nyob twj ywm;Txhim kho cov kab font kom raug, zam kom tsis txhob muaj cov ntawv xim xim plooj thiab mob stroke poob, tshwj xeeb tshaj yog qhov txhaum ntawm txoj kab slash
Tsob ntoo ntuj tsim duab
NMSC natural image processing
Ntuj scenes ua tiav los ntawm Nova NSMC ntse duab coding tshuab:
cov duab kev ntxhib los mos cov ntaub ntawv tso saib ua tiav, zoo txo cov ntug jagged kev nkag siab, kev hloov, du, exquisite nyhuv.
Tag nrho txuas 4K @ 60Hz qhia tau hais tias du jam
Ib txwm faib video refresh npaum li cas tsuas yog ua tau 30Hz, thiab faib siv HFR (siab-nce tus nqi) siab ncej tus nqi thev naus laus zis, kev ua yeeb yaj kiab hloov tshiab rau 60Hz, thiab los ntawm kev sau cov tswv yim, kev txiav txim siab tso tawm, txhawb nqa tag nrho txuas 4K @ 60Hz, qee qhov scenarios refresh npaum li cas tuaj yeem ncav cuag 120Hz, qis li 60ms ncua, daws qhov luag, ncua, thiab lwm yam.60FPS
Net Sync + Nova Sync nanosecond theem Sync
Raws li Net network synchronization raws tu qauv thiab ua ke nrog lub cim Nova Sync kho vajtse synchronization thev naus laus zis ntawm Nova, Tianquan faib system paub txog qhov tseeb synchronization ntawm lub kaw lus tso zis moos, thiab tseem tuaj yeem tuav lub xeev zoo synchronization rau lub sijhawm ntev, txawm tias piv rau lub synchronization ntawm centralized pab kiag li lawm.Tiag tiag nanosecond theem synchronization uas tuaj yeem tiv taus qhov kev sim ob zaug ntawm qhov muag liab qab thiab lub koob yees duab
NMSC natural image processing
Ntxiv rau qhovLED zaub, Tianquan kuj tseem txhawb nqa qhov projection, LCD thiab lwm yam khoom siv puv npo.Thiab txhawb kev daws teeb meem tag nrho (txwv qhov dav, siab 819 2), kom ua tau raws li cov kev xav tau ntawm qee qhov ultra-wide, ultra-high screen lub cev xav tau.Tsis tas li ntawd, synchronous splicing kuj tuaj yeem ua tiav hauv ntau cov ntxaij vab tshaus nrog qhov sib txawv ntawm qhov dav thiab qhov siab, uas daws qhov teeb meem uas lwm yam ntau lub tshuab tsis tuaj yeem kho qhov kev daws teeb meem, ua rau kev ua haujlwm tsis zoo.
NMSC natural image processing
Nyob rau hauv qhov chaw hais kom ua, cov ntaub ntawv chaw thiab lwm yam kev faib tawm tau dhau los ua ntau thiab ntau dua siv niaj hnub no, ntau hom kev xav tau, nova fais fab faib qhov system tuaj yeem ua tau zoo dua.LED nposaj zawg zog, ruaj khov, ua haujlwm yooj yim, thiab ntau lwm yam yuav tsum tau ua, thiab xyuas kom meej cov duab zoo tso saib, yog qhov tsim nyog tshaj plaws rau qhov loj-scale suab thiab video xav tau, feem ntau nkag siab txog LED faib kev daws teeb meem.
