Siab txhaisSDI optical transceiveryog evolved raws li zoo tib yam digital video optical transceiver, siv H.264 encoding txoj kev, feem ntau siv SDI interface.

SD / HD / 3G-SDI optical transceiver cov khoom yog thawj zaug tsim thiab siv los ntawm cov neeg siv khoom hauv xov tooj cua thiab TV kev lag luam. Lawv tau siv nyob rau hauv TV studios thiab tshaj tawm nyob rau hauv Universiade, thiab tom qab ntawd txuas ntxiv mus rau thaj tsam ntawm 1080P kev soj ntsuam siab, nrog cov ntaub ntawv rov qab tswj; tus nqi yog 1.485G (tseem hu ua 1.5 G, sib haum rau SMPTE-292M tus qauv, txhawb nqa 720P) thiab 2.97G (tseem hu ua 3G, sib haum rau SMPTE-424M tus qauv, txhawb nqa FULL HD 1080P). Xyuas kom meej tias tsis muaj qhov txaws npo, lub vijtsam dub thiab lwm yam tshwm sim thaum lub sijhawm xa cov duab siab.

Lub siab-txhais SDI optical transceiver txais kev tshaj lij tsis muaj kev tshaj tawm digital high-txhais yees duab thiab high-speed digital optical fiber kis tshuab. Tom qab hloov lub 1.485Gbps HD-SDI cov teeb liab rau hauv lub teeb liab kho qhov muag, nws tuaj yeem xa mus rau ntawm qhov muag fiber ntau rau 1-20 kilometers thiab rov qab mus rau lub teeb liab hluav taws xob. Haum rau SDI video soj ntsuam thiab ntev-ntev video capture. Qhov no series ntawm optical transceivers muaj kev ua tau zoo ruaj khov, cov duab meej zoo, kev ruaj ntseg siab, thiab cov teeb meem ntawm LED, uas tuaj yeem soj ntsuam kev ua haujlwm ntawm optical transceiver.

HD tswvyim
Cia peb saib dab tsi 1080i thiab 1080p sawv ntsug rau - ob qho tib si 1080i thiab 720p yog thoob ntiaj teb lees paub cov qauv HDTV digital. Tsab ntawv kuv stands rau interlaced scanning, thiab tsab ntawv P stands rau progressive scanning. 1080 thiab 720 sawv cev rau kev daws teeb meem uas tuaj yeem ua tiav hauv txoj kev ntsug. 1080P yog tam sim no tus qauv siab tshaj plaws hauv tsev HD teeb liab hom.

Cov digital high-txhais TV uas txhua tus neeg feem ntau hais txog kev siv cov thev naus laus zis thev naus laus zis hauv tag nrho cov txheej txheem tshaj tawm thiab tau txais cov xov xwm hauv TV xws li tua, kho, tsim khoom, tshaj tawm, xa tawm, thiab txais tos. Digital high-txhais TV yog qhov ua tau zoo tshaj plaws ntawm cov TV digital (DTV) cov qauv, luv luv li HDTV. Nws yog lub TV siab daws teeb meem nrog tsawg kawg 720 kab rov tav scan kab, 16: 9 widescreen hom, thiab ntau-channel kis tau tus mob. Muaj peb hom kev luam theej duab rau HDTV, uas yog 1280 * 720p, 1920 * 1080i thiab 1920 * 1080p. kuv lub teb chaws txais yuav 1920 * 1080i / 50Hz.
