Lub koob yees duab ntawm lub nkoj txuas nrog digital video sender--- video sender wirelessly xa video pub rau video receiver-- receiver connects with GCS---GCS show the video stream to people on ground.

 

Drone HD video transmitterthiab receiver muaj 3 yam tseem ceeb:

 

● HD

● Zero latency

● Ntev nrug

 

Peb cov yam ntxwv no yog dab tsi cov neeg siv drone txhawj xeeb tshaj plaws thiab tseem yog qhov lawv feem ntau nkag siab yuam kev.Hauv tsab xov xwm no peb yuav piav qhia 3 cov ntsiab lus no.

 

Siab txhais

 

Qhov "siab txhais" hauv drone high-txhais video kis tau tus mob yog qhov txawv me ntsis ntawm lub tswv yim ntawm HD TV.Cov txheej txheem txhais ntawm TV yog: siab txhais (720P), Full HD (1080P), ultra siab txhais (4K).Cov qauv HD no yog tus cwj pwm los ntawm kev daws teeb meem.Nyob rau hauv txoj kev no, tsis tshua muaj kev saib xyuas rau lub tswv yim ntawm "video streaming rate."

 

Raws li tib lub full HD video, yog hais tias tus kwj tus nqi sib txawv, cov video sharpness yuav txawv.Yog tus nqi ntws zoo ib yam.Txawm li cas los xij, siv txoj kev sib txawv video compression, video zoo yuav txawv.

 

Cov compression tau hais los saum toj no yog txoj hauv kev rau compress video.H.264 thiab H.265 yog txoj hauv kev rau compressing video.Txawm li cas los xij h.265 yog ib qho kev siv tshuab ntau dua li H.264.

 

Vim li cas cov yeeb yaj kiab yuav tsum tau compressed?Cia kuv qhia koj qhov sib npaug: Ib ob ntawm cov ntaub ntawv rau 1080P60 video yog 1920 * 1080 * 32 * 60 = 3,981,312,000 khoom, uas yog hais txog 4Gb / s.Txawm tias siv fiber ntau optics los xa cov ntaub ntawv ntau npaum li cas yuav siv sij hawm.Tsis txhob hais txog kev siv qhov txwv bandwidth wireless txuas txuas kom xa cov kwj video loj.Yog li cov koom haum thoob ntiaj teb tau pom zoo rau tus qauv thiab txoj hauv kev uas compresses video rau kev sib kis thiab decompresses tom qab tau txais nws.

 

Lub compression efficiency ntawm H.265 yog ob zaug ntawm H.264.Cov yeeb yaj kiab compressed los ntawm H.265 yog qis qis dua li compressed los ntawm H.264.Yog li ntawd, "HD" nyob rau hauv lub hd video kis tau tus mob ntawm drones, ib tug ntau tsim nyog kev nkag siab yuav tsum tau zoo video.

Tib qhov kev daws teeb meem thiab tib txoj kev compression encoding, qhov siab dua tus nqi me ntsis, qhov zoo dua qhov video zoo.

Tib qhov kev daws teeb meem thiab tib tus nqi me ntsis, txoj kev compression coding H.265 muaj cov duab zoo dua H.264.

Txhawm rau kom muaj peev xwm xa cov kwj video kom meej dua rau cov neeg siv, txhua tusWIAVE drone wireless txuastxais yuav H.264+H.265 algorithms thiab built-in encoders thiab decoders hauv transmitter thiab receiver.

 

Latency

 

"Zero latency" yog ib lub tswv yim uas tau hyped los ntawm ntau manufacturers.

"Zero ncua" yog qhov tseeb lub tswv yim txheeb ze.Lub sijhawm pom qhov muag ntawm tib neeg lub qhov muag yog 100 ~ 400ms.Yog li ntawd, "zero ncua" yog lub hom phiaj uas txhua qhov kev sib txuas lus hauv lub sijhawm tiag tiag tab sis ua tsis tau.Thiab nyob rau hauv cov txheej txheem siv tiag tiag, qhov ncua sij hawm pom los ntawm tib neeg lub qhov muag kuj los ntawm kev ncua ntawm lub koob yees duab thiab GCS zaub.Kev ncua ntawm wireless kis tau tus mob tsuas yog ib feem ntawm nws.

IWAVE drone digital downlink latency yog li ntawm 20-80ms los ntawm kev xa tawm ntawm lub nkoj thiab cov neeg txais hauv av.

 

Ntev Ntev

 

Ntev ntau yog yooj yim to taub, nws yog ib qho teeb meem RF.Tam sim no, ntau yam khoom siv feem ntau ntxiv "LOS" thaum kos qhov kev sib txuas lus nyob deb (LOS hais txog qhov kev ncua deb ntsuas hauv huab cua tsis muaj kev cuam tshuam).

IWAVE R&D pab pawg tsom mus rau ntau yam video thiab telemetry cov ntaub ntawv sib txuas lus txuas rau drone, UGV, UAV thiab USV.
