Kutanthauzira kwaukadaulo wa HDMI2.1 cholumikizira

Cholumikizira cha HDMI 2.1 chawona zosintha zambiri pamagetsi ndi magwiridwe antchito akuthupi poyerekeza ndi mtundu wa HDMI 1.4. Tiyeni tifufuze chilichonse mwazosinthazi:

1, Kuchulukitsa Kuyesa Kwambiri Kwambiri kwa Zolumikizira za HDMI:

Pamene kufunikira kwa kufala kwa deta yapamwamba, makamaka kwa 4K ndi 8K Ultra HD (UHD) TV, kumakwera, HDMI imakhala yofunikira pa kusamutsa deta yodalirika pakati pa gwero (wosewerera kanema) ndi wolandira (TV). Ndi mitengo yapamwamba ya deta, kugwirizanitsa pakati pazidazi kumakhala cholepheretsa kufalitsa deta yodalirika. Kulumikizana kumeneku kungayambitse nkhani za Signal Integrity (SI) monga Electromagnetic Interference (EMI), crosstalk, Inter-Symbol Interference (ISI), ndi jitter yamagetsi. Chifukwa chake, ndikukwera kwamitengo ya data, kapangidwe ka cholumikizira cha HDMI 2.1 chayamba kuganizira za SI. Zotsatira zake, kuyesa kwa mayanjano kwawonjezera zofunikira pakuyesa pafupipafupi kwambiri. Kupititsa patsogolo magwiridwe antchito a SI a zolumikizira za HDMI, opanga zolumikizira asintha mawonekedwe a zikhomo zachitsulo ndi zida za dielectric molingana ndi malamulo opangira komanso kudalirika kwamakina kuti akwaniritse zofunikira zoyezetsa pafupipafupi.

2, Zofunikira Zowonjezera Bandwidth za HDMI 2.1 zolumikizira:

HDMI 2.0 yam'mbuyomu inali ndi 18Gbps koma sanatanthauze zingwe zatsopano za HDMI kapena zolumikizira. HDMI 2.1, kumbali ina, imadzitamandira kuwirikiza kawiri, kulola ma bandwidths mpaka 48 Gbps. Ngakhale zingwe zatsopano za HDMI 2.1 zidzabwerera m'mbuyo zimagwirizana ndi zida za HDMI 1.4 ndi HDMI 2.0, zingwe zakale sizingagwirizane ndi zatsopano. Zolumikizira za HDMI 2.1 zimakhala ndi njira zinayi za data: D2, D1, D0, ndi CK, momwe deta imafalikira mosiyanasiyana. Pamene tchanelo chilichonse chimagawana mawonekedwe amagetsi ofanana, zolumikizira za HDMI 2.1 ziyenera kuwonetsa magwiridwe antchito apamwamba a SI kuti akwaniritse 48Gbps bandwidth ya cholumikizira cham'badwo wotsatira cha HDMI.

3, Zofunikira Zowonjezera Zosiyanasiyana:

Kuyesa kolumikizira kwa HDMI 2.1 kumagwera pansi pa Gulu 3, pomwe kuyesa kwa HDMI 1.4 kugwera pansi pa Gulu 1 ndi Gulu 2. Pambuyo pa HDMI 2.1, mawonekedwe olumikizira amangokhala a Mtundu A, C, ndi D, wokhala ndi mawonekedwe omwe amagwiritsidwa ntchito kale a Type E makamaka pamagalimoto. munda ukuthetsedwa. Kuti muwonjezere mawonekedwe amagetsi kuti akwaniritse miyezo ya HDMI 2.1, mapangidwe olumikizira amafunikira kusinthidwa kuti apange magawo monga m'lifupi, makulidwe, ndi kutalika kwa zikhomo zachitsulo. Opanga ena angagwiritsenso ntchito njira zina, monga kuyambitsa mipata mu socket's dielectric material, kuti achepetse kugwirizanitsa mphamvu. Pamapeto pake, magawo ovomerezeka apangidwe ayenera kukwaniritsa magawo a impedance. Zolumikizira za HDMI 2.1 zimapereka magwiridwe antchito abwinoko a SI kuposa masinthidwe am'munsi apansi, ndipo opanga zolumikizira zofananira adzagwiritsa ntchito zida zosiyanasiyana zowongolera.
