Dab tsi yog Qhov Zoo ntawm Lub Koob Yees Duab Module Nrog H264?
Lub ntsiab kom zoo dua ntawm lub koob yees duab module nrog H264 nyob rau hauv nws cov kev kho vajtse video encoder, uas coj kev txhim kho tseem ceeb rau kev tsim thiab kev ua tau zoo.
Tseem ceeb txo tag nrho lub zog siv zog
Video encoding yog ib txoj haujlwm uas siv computer ntau heev. Los ntawm kev tuav cov encoding nrog nws cov khoom siv tshwj xeeb, qhov module no tshem tawm lub zog no - tshem tawm txoj haujlwm los ntawm lub ntsiab processor. Qhov no ua rau txo qis tag nrho kev siv hluav taws xob rau tag nrho cov kab ke, uas yog qhov tseem ceeb rau cov roj teeb -IoT cov khoom siv hluav taws xob, cov khoom siv nqa tau yooj yim, thiab kev ua haujlwm txuas ntxiv.
Zoo heev Offloads tus tswv processor
Lub luag haujlwm hnyav ntawm H264 encoding yog ua haujlwm ntawm nws tus kheej hauv module nws tus kheej. Tus tswv tsev processor (CPU/SoC) tsuas yog yuav tsum tau txais thiab ua cov uas twb muaj lawm - compressed, lub teeb yuag video streaming, tso tawm nws cov peev txheej muaj txiaj ntsig. Qhov no tso cai rau tus tswv tsev ua haujlwm tsom mus rau cov neeg siv kev siv, AI algorithms, lossis lwm yam haujlwm tseem ceeb dua.
Ua kom txo qis cov ntaub ntawv hloov pauv Bandwidth xav tau
H264 encoding compresses loj heev raw cov ntaub ntawv video rau hauv me me heev. Yog li ntawd, lub bandwidth xav tau rau cov ntaub ntawv hloov ntawm lub module thiab tus tswv processor yog tsawg heev. Qhov no ua rau kev sib kis tau yooj yim ntawm siab -txhais video txawm tias qeeb qeeb xws li USB 2.0 thiab txo qhov nyuaj thiab tus nqi ntawm kev xa xov wireless, ua rau nws zoo tagnrho rau Wi-Fi lossis 4G/5G network daim ntawv thov.
Simplifies System Design thiab Integration
Qhov module no muaj "plug-thiab-play" daws. Cov neeg tsim khoom tsis tas yuav sau cov software nyuaj encoding lossis sib koom ua ke cov tsev qiv ntawv codec loj. Lawv tsuas yog yuav tsum tau txais thiab khaws cia / ua cov kwj H264 raws li cov txheej txheem kev cai. Qhov no ua rau luv luv txoj kev loj hlob thiab txo cov software nyuaj thiab nqi.
Ua kom muaj kev ntseeg siab dua thiab ruaj khov
Encapsulating lub encoding muaj nuj nqi nyob rau hauv ib tug standalone module txo kev vam khom rau lub host system software. Txawm hais tias lub ntsiab processor tau ntsib luv luv vim yog kev siv cov kev siv nyuaj, lub koob yees duab module tus kheej encoding thiab cov zis feem ntau tuaj yeem nyob ruaj khov. Qhov no ua kom muaj kev ntseeg siab dua cov yeeb yaj kiab, uas yog qhov tseem ceeb rau cov ntawv thov uas tsis tuaj yeem zam kev cuam tshuam, xws li kev soj ntsuam kev ruaj ntseg.
Lub Koob Yees Duab Module Nrog H264 Ua Haujlwm li cas?
Lub koob yees duab module nrog H264 siv nws cov khoom siv tshwj xeeb sib xyaw ua kom tiav tag nrho cov txheej txheem los ntawm cov duab ntes mus rau compressed tso zis. Nws txoj kev ua haujlwm tuaj yeem raug sau tseg rau hauv plaub theem hauv qab no:
1.Image Capture: Cov duab sensor ntawm lub module hloov lub teeb ntes los ntawm lub lens mus rau hauv cov khoom siv hluav taws xob tsis zoo, tsim cov ntaub ntawv raw cov ntaub ntawv uas tsis tau ua tiav.
2.Signal Processing: Cov ntaub ntawv nyoos yog pub rau hauv Image Signal Processor (ISP). ISP ua ntau yam tseem ceeb ntawm cov duab zoo, suav nrog txo suab nrov, pib- raug, pib- dawb tshuav, kho xim, thiab ua kom zoo. Nws thaum kawg outputs siab - zoo video thav duab (xws li, nyob rau hauv YUV hom) npaj rau encoding.
3.H264 Hardware Encoding: Qhov no yog kauj ruam tseem ceeb tshaj plaws. Cov txheej txheem video thav duab los ntawm ISP tsis tso tawm ncaj qha. Hloov chaw, lawv raug xa mus rau H264 Hardware Encoder sib xyaw hauv lub module. Cov nti tshwj xeeb no tsom xam thiab compresses cov video thav duab hauv lub sijhawm tiag tiag, siv cov txheej txheem xws li intra-frame thiab inter-frame kev kwv yees kom tshem tawm spatial thiab temporal redundancies, thiab tom qab ntawd entropy encodes cov txiaj ntsig los tsim kom muaj kev sib tw, cov qauv-raws li H264 bitstream.
4.Output kwj: Thaum kawg, lub module outputs compact H264 bitstream los ntawm nws lub cev interface, es tsis txhob bulky nyoos video ntaub ntawv. Cov kwj no tuaj yeem xa tau yooj yim mus rau tus tswv tsev processor ntawm kev sib txuas xws li USB, Ethernet, lossis Wi-Fi. Tus tswv tsev processor tuaj yeem siv nws ncaj qha rau kev khaws cia, network streaming, lossis kev tshuaj xyuas ntxiv yam tsis tas yuav compress nws dua.
