Mawonekedwe a HDMI ndi tsatanetsatane

Malingaliro omwe akukhudzidwa ndi awa:

TMDS: (Nthawi Yochepetsedwa Chizindikiro Chosiyanitsa) Kutumiza chizindikiro chosiyana kocheperako, ndi njira yotumizira chizindikiro chosiyana, njira yotumizira chizindikiro cha HDMI yogwiritsidwa ntchito motere.

HDCP: (Chitetezo cha Zamkati Zapaintaneti Chapamwamba) Chitetezo cha Zamkati Zapaintaneti Chapamwamba.

DDC: Njira Yowonetsera Deta

CEC: Kulamulira Zamagetsi Zamagetsi kwa Ogwiritsa Ntchito

EDID: Deta Yodziwika Kwambiri Yowonetsera

E-EDIO: Deta Yowonjezera Yozindikiritsa Zowonetsera Zowonekera

Kuyimira kwawo mu njira yotumizira ma HDMI kuli motere:

Kupanga mtundu wa HDMI

HDMI 1.0

Mtundu wa HDMI 1.0 unayambitsidwa mu Disembala 2002, chinthu chake chachikulu ndi kuphatikiza mawonekedwe a digito a audio stream, kenako mawonekedwe a PC ndi otchuka poyerekeza ndi mawonekedwe a DVI, ndi apamwamba kwambiri komanso osavuta kugwiritsa ntchito.

Mtundu wa HDMI 1.0 umathandizira kutsitsa makanema kuchokera ku DVD kupita ku mtundu wa Blu-ray, ndipo uli ndi ntchito ya CEC (consumer electronics control), ndiko kuti, mu pulogalamuyi, mutha kupanga ulalo wofanana pakati pa zida zonse zolumikizidwa, gulu la chipangizocho lili ndi ulamuliro wosavuta.

HDMI 1.1

Kuyankhulana kwa HDMI version 1.1 mu Meyi 2004. Kuwonjezera thandizo la mawu a DVD.

HDMI 1.2

Mtundu wa HDMI 1.2 unayambitsidwa mu Ogasiti 2005, makamaka kuti athetse vuto la HDMI 1.1, thandizo lake ndi lochepa, ndipo mavuto okhudzana ndi zida zamakompyuta ndi ofanana. Mtundu wa 1.2 wa wotchi ya pixel umayenda pa 165 MHz ndipo kuchuluka kwa deta kumafika pa 4.95 Gbps, kotero 1080 P. Zingaganiziridwe kuti mtundu wa 1.2 umathetsa vuto la 1080P la TV ndi vuto la point-to-point la kompyuta.

HDMI 1.3

Mu June 2006, kusintha kwa HDMI 1.3 kunabweretsa kusintha kwakukulu pa ma frequency a single-link bandwidth kufika pa 340 MHz. Izi zithandiza ma TV a LCD awa kupeza kutumiza deta ya 10.2Gbps, ndipo mtundu wa 1.3 wa mzerewu umapangidwa ndi ma pair anayi a ma transmission channels, omwe awiriawiri a ma transmission channel ndi clock channel, ndipo ma pair ena atatu ndi ma TMDS channels (kuchepetsa kutumiza kwa ma differential signals), liwiro lawo lotumizira ndi 3.4GBPs. Kenako ma pair atatu ndi 3 * 3.4 = 10.2 GPBS imatha kukulitsa kwambiri kuzama kwa mtundu wa 24-bit womwe umathandizidwa ndi HDMI1.1 ndi 1.2 versions kufika pa 30, 36 ndi 48 bits (RGB kapena YCbCr). HDMI 1.3 imathandizira 1080 P; Zina mwa 3D zosafunikira kwambiri zimathandizidwanso (mwachiphunzitso sizithandizidwa, koma kwenikweni zina zimatha).

HDMI 1.4

Mtundu wa HDMI 1.4 ukhoza kale kuthandizira 4K, koma umadalira bandwidth ya 10.2Gbps, kuchuluka kwake kungangofikira 3840 × 2160 resolution ndi 30FPS frame rate.

HDMI 2.0

Bandwidth ya HDMI 2.0 yakulitsidwa kufika pa 18Gbps, imathandizira kulumikizidwa kokonzeka kugwiritsidwa ntchito komanso kotentha, imathandizira 3840 × 2160 resolution ndi 50FPS, 60FPS frame rates. Nthawi yomweyo, pothandizira mawu mpaka njira 32, komanso kuchuluka kwa zitsanzo za 1536 kHz. HDMI 2.0 sikutanthauza mizere yatsopano ya digito ndi zolumikizira, ma interfaces, kotero imatha kusunga kulumikizana kwabwino kumbuyo ndi HDMI 1.x, ndipo mitundu iwiri yomwe ilipo ya mizere ya digito ingagwiritsidwe ntchito mwachindunji. HDMI 2.0 sidzalowa m'malo mwa HDMI 1.x, koma kutengera ndi zowonjezera zomaliza, chipangizo chilichonse chothandizira HDMI 2.0 chiyenera choyamba kutsimikizira chithandizo choyambirira cha HDMI 1.x.

Hdmi 2.1

Muyezowu umapereka bandwidth yofika pa 48Gbps, ndipo makamaka, muyezo watsopano wa HDMI 2.1 tsopano ukuthandizira 7680 × 4320 @ 60Hz ndi 4K @ 120hz. 4 K ili ndi ma pixel 4096 × 2160 ndi ma pixel 3840 × 2160 a 4 K yeniyeni, pomwe mu HDMI 2.0, 4 K @ 60Hz yokha ndi yomwe imathandizidwa.

Mtundu wa Chiyankhulo cha HDMI:

Mtundu A HDMI Mtundu A ndi womwe umagwiritsidwa ntchito kwambiri Chingwe cha HDMI ndi ma pin 19, m'lifupi 13.9 mm ndi makulidwe 4.45 mm. Zipangizo zonse za TV kapena kanema, zomwe zili ndi kukula kotere kwa mawonekedwe, Mtundu A uli ndi ma pin 19, m'lifupi mwake 13.9 mm, makulidwe ake 4.45 mm, ndipo tsopano 99% ya zida zamawu ndi makanema zomwe zimagwiritsidwa ntchito tsiku ndi tsiku zili ndi kukula kotere kwa mawonekedwe. Mwachitsanzo: Blu-ray player, millet box, notebook computer, LCD TV, projector ndi zina zotero.

Mtundu B Mtundu wa HDMI B ndi wosowa kwambiri pa moyo. Cholumikizira cha HDMI B chili ndi ma pin 29 ndi mulifupi wa 21 mm. Mphamvu yosamutsa deta ya HDMI B Mtundu ndi yofulumira kwambiri kuposa Mtundu wa HDMI A ndipo ndi yofanana ndi DVI Dual-Link. Popeza zida zambiri zamawu ndi makanema zimagwira ntchito pansi pa 165MHz, ndipo pafupipafupi yogwiritsira ntchito Mtundu wa HDMI B ndi yoposa 270MHz, ndi "yovuta" kwambiri pamapulogalamu apakhomo, ndipo tsopano imagwiritsidwa ntchito pokhapokha pazochitika zina zaukadaulo, monga WQXGA 2560 × 1600 resolution.

Mtundu wa HDMI C wa Mtundu C, womwe nthawi zambiri umatchedwa Mini HDMI, umapangidwira makamaka zipangizo zazing'ono. Mtundu wa HDMI C umagwiritsanso ntchito ma pin 19, kukula kwake kwa 10.42 × 2.4 mm ndi kocheperako ndi 1/3 kuposa Mtundu A, mtundu wa mapulogalamu ndi wochepa kwambiri, makamaka mu zipangizo zonyamulika, monga makamera a digito, osewera onyamulika ndi zida zina.

Mtundu wa D Mtundu wa HDMI D umadziwika kuti Micro HDMI. Mtundu wa HDMI D ndi mtundu waposachedwa kwambiri wa mawonekedwe, womwe umachepetsedwa kukula. Kapangidwe ka ma pin a mizere iwiri, komwe kali ndi ma pin 19, ndi 6.4 mm m'lifupi ndi 2.8 mm makulidwe, mofanana ndi mawonekedwe a Mini USB. Amagwiritsidwa ntchito kwambiri m'zida zazing'ono zam'manja, zoyenera kwambiri pazida zonyamulika komanso zamagalimoto. Mwachitsanzo: mafoni am'manja, mapiritsi, ndi zina zotero.

Mtundu wa E (Mtundu wa E) Mtundu wa HDMI E umagwiritsidwa ntchito makamaka potumiza mawu ndi makanema azinthu zosangalatsa zomwe zili mgalimoto. Chifukwa cha kusakhazikika kwa malo ozungulira mkati mwa galimoto, Mtundu wa HDMI E wapangidwa kuti ukhale ndi zinthu monga kukana chivomerezi, kukana chinyezi, kukana mphamvu zambiri, komanso kulekerera kutentha kwakukulu. Mu kapangidwe kake, kapangidwe ka makina kamatha kutsimikizira kudalirika kwa kulumikizana.
