Kev zoo yog lub ntsiab tseem ceeb ntawm HD lub koob yees duab kev txhim kho
HD video conferencing tau hloov dua siab los ntawm tus thawj SD video conferencing ntaus ntawv mus rau lub kaw lus nruab nrab ntawm HD yees duab rau pem hauv ntej-kawg video / suab ntes, video / suab zaub, yees duab ib zaug / suab compression, kis duab, post-saib / audio editing , sau Nws yuav tsum tau ua ib ncig HD, thiab ib lub nplhaib yog ib yam khoom uas tsis yog HD. Txawm hais tias cov duab thiab lub suab yuav tsum tau tso tawm kom pom tsis muaj kev yuam, tus HD zoo yuav pib ua SD zoo.
Zoo sib xws, kev yees duab rau pem hauv ntej-kawg, HD koob yees duab tsuas yog qhov kev daws teeb meem nkaus xwb. Tus qauv ntaus ntawv ntaus nqi rau cov qauv siv yees qauv yog 1/4 CCD, los yog CMOS. Lub pixel kuj yog ntawm 400,000 thiab 500,000. Rau cov koob yees duab-txhais, cov cuab yeej duab yog feem ntau 3 * 1 / 3CCD los yog CMOS, thiab cov pixels yog 100 thiab 2 lab. Xav txog qhov tseem ceeb ntawm qhov txuas, HD koob yees duab thiab HD video conferencing terminals yog feem ntau txuas ntawm lub HD-SDI interface. Nws tuaj yeem tau txog li 100 metres.

Yog li ntawd, yuav ua li cas rau lawv, txoj kev nyob deb, thiab cov khoom siv los siv yog cov teeb meem peb yuav tsum xav txog. Xwb HD-SDI yog peb tsuas daws, vim hais tias nws cia coaxial cable xa tawm tseg tsis tau poob 100 meters. Thiab nrog lub taub hau BNC ua rau kab ntawv yooj yim heev, tsis xav tau cov cables thiab connectors, koj tuaj yeem yuav nws ntawm cov kiab khw hauv computer thiab lub khw muag khoom.
