Chiyambi cha Kusintha kwa Mafotokozedwe Kuchokera ku HDMI 1.0 kupita ku HDMI 2.1 (Gawo 1)

Chiyambi cha Kusintha kwa Mafotokozedwe Kuchokera ku HDMI 1.0 kupita ku HDMI 2.1 (Gawo 1)

Kuyambira pomwe Samsung BD-P1000 idatulutsa wosewera woyamba wa Blu-ray padziko lonse lapansi mu 2006, womwe udagwiritsa ntchito HDMI, osewera ambiri a Blu-ray ndi zida zosewerera za Full HD zakhala ndi HDMI. Kuyambira pamenepo, HDMI yakhala yosaletseka ndipo yakhala ikulamulira makampani opanga ma chingwe kwa zaka zambiri, ikukhudza magawo onse ogulitsa komanso opanga ma audio ndi makanema.

Kusintha kwa mitundu ya HDMI

1.4 ndi 2.0 ndi zomwe zimafala kwambiri

2.0a imathandizira 4K HDR
HDMI 1.0
Imathandizira Blu-ray ndi Full HD 1080/60Hz
HDMI 1.0 idatulutsidwa pa Disembala 9, 2002. Ndi cholumikizira cha digito cha audio/kanema chokhala ndi mzere umodzi. Kapangidwe ka ulalo kamachokera pa DVI ndipo kamagwiritsa ntchito mtundu womwewo wa kutumiza makanema, koma kamatumiza mawu ndi deta ina yothandizira panthawi yowonera makanema. HDMI 1.0 imalola wotchi yayikulu ya TMDS ya 165 MHz (bandwidth ya ulalo uliwonse ndi 4.95 Gbit/s), yofanana ndi DVI. Imafotokoza mitundu iwiri ya zolumikizira zotchedwa A-type ndi B-type, zomwe motsatana zimagwiritsa ntchito ma pinout kutengera zolumikizira za DVI-D ya single-link ndi DVI-D ya dual-link, ngakhale cholumikizira cha B-type sichinagwiritsidwepo ntchito mu malonda aliwonse. HDMI 1.0 imagwiritsa ntchito 8 b/10 b encoding potumiza makanema, ndikuyipatsa bandwidth ya kanema ya 3.96 Gbit/s (1920×1080 kapena 1920×1080 60Hz) ndi 8-channel LPCM/192 kHz/24-bit audio. HDMI 1.0 imafuna chithandizo cha kanema wa RGB, ndipo mwina imathandizira Y′CBCR 4:4:4 ndi 4:2:2 (yokakamizidwa ngati chipangizocho chikuthandizira ma interface ena a Y′CBCR). Kuzama kwa mtundu wa 10 bpc (30 bits/pixel) kapena 12 bpc (36 bits/pixel) kumalola kugwiritsa ntchito 4:2:2 subsampling, koma kuzama kwa mtundu wa 8 bpc (24 bits/pixel) kokha ndiko komwe kumaloledwa mukagwiritsa ntchito RGB kapena Y′CBCR 4:4:4. Malo amtundu wa Rec. 601 ndi Rec. 709 okha ndi omwe amathandizidwa. HDMI 1.0 imalola makanema apadera okha, kuphatikiza mitundu yonse yomwe yafotokozedwa mu EIA/CEA-861-B ndi mitundu ina yomwe yatchulidwa mu HDMI specification. Magwero/olandila onse a HDMI ayeneranso kutumiza/kulandira kanema wa DVI wa single-link ndikutsatira kwathunthu specification ya DVI.
Mtundu woyamba wa HDMI, womwe unatulutsidwa mu Disembala 2002, unganenedwe kuti unapangidwira mapulogalamu athunthu a HD monga Blu-ray panthawiyo. Mbali yake yayikulu ndikuphatikiza makanema ndi mawu nthawi imodzi. Poyerekeza ndi ma interfaces enieni otumizira makanema pamakompyuta monga DVI ndi DisplayPort, ndi yoyenera kwambiri zida zomvera ndi kuwona. HDMI 1.0 imathandizira kale makanema a DVD ndi Blu-ray, yokhala ndi bandwidth yayikulu ya 4.95 Gbps, yomwe 3.96 Gbps imagwiritsidwa ntchito potumiza makanema, yomwe imatha kuthandizira 1080/60p kapena UXGA resolution; pankhani ya mawu, imathandizira 8-channel LPCM 24bit/192kHz, zomwe zikutanthauza kuti yafika kale pa multi-channel Hi-Res audio. Poyerekeza ndi ma cable specifications panthawiyo, inali yolimba kwambiri.

HDMI 1.1

HDMI 1.1 idatulutsidwa pa Meyi 20, 2004, ndipo idawonjezera thandizo la DVD-Audio.
Inayambitsidwa mu Meyi 2004 ndipo inali ndi chithandizo chatsopano cha DVD-Audio. DVD-Audio imasunga nyimbo za PCM za 16-bit/44.1kHz mpaka 24-bit/192kHz pama DVD disc. Poyamba cholinga chake chinali cholowa m'malo mwa CD mofanana ndi SACD, koma mwatsoka, mitundu yonse iwiri sinatchulidwe kwambiri.
HDMI 1.2
Thandizo la SACD
Inatulutsidwa mu Ogasiti 2005, ndikuwonjezera chithandizo cha audio ya 1-bit, yomwe imadziwikanso kuti SACD audio streaming, mpaka njira 8. DMI CEC imalola remote control imodzi kulamulira zipangizo zonse zogwirizana, zomwe ndi zosavuta kwambiri.
HDMI 1.2 idatulutsidwa pa Ogasiti 8, 2005, ndipo idawonjezera njira yomvera pang'ono ya Super Audio CD, mpaka njira 8. Kuti HDMI ikhale yoyenera kugwiritsidwa ntchito pazida za PC, mtundu 1.2 udachotsanso kufunikira kogwiritsa ntchito mitundu yothandizidwa mwachindunji. Inawonjezera kuthekera kwa opanga kupanga mitundu yeniyeni kwa wogulitsa, zomwe zimalola kuti pakhale resolution iliyonse ndi refresh rate, osati mndandanda womwe wafotokozedwa kale wamitundu yothandizira. Kuphatikiza apo, idawonjezera chithandizo chodziwikiratu cha mitundu yatsopano kuphatikiza 720p pa 100 ndi 120Hz ndi zofunikira zothandizira mawonekedwe a pixel omasuka, kotero kuti magwero okhala ndi kutulutsa kwa RGB (PC) kokha sangafunike kuthandizira kutulutsa kwa Y′CBCR.
