Intangiriro ku bisobanuro by'impinduka kuva kuri HDMI 1.0 kugera kuri HDMI 2.1 (Igice cya 1)

Kuva aho hasohokeye icyuma cya mbere cya Blu-ray ku isi, Samsung BD-P1000, mu 2006, cyakoresheje HDMI, umubare munini w’ibikoresho bya Blu-ray n’ibikoresho bya HD byose byashyizwemo HDMI. Kuva icyo gihe, HDMI yakomeje kuba nta guhagarika kandi imaze imyaka myinshi yiganje mu nganda z’insinga, ikora ku buryo bwo kohereza amajwi n’amashusho haba ku bakoresha ndetse no mu nganda.

Iterambere rya verisiyo za HDMI

1.4 na 2.0 ni byo bikunze kugaragara cyane

2.0a ishyigikira 4K HDR
HDMI 1.0
Ishyigikira Blu-ray na Full HD 1080/60Hz
HDMI 1.0 yasohotse ku ya 9 Ukuboza 2002. Ni umurongo umwe w’itumanaho ry’amajwi/amashusho. Imiterere y’itumanaho ishingiye kuri DVI kandi ikoresha uburyo bumwe bwo kohereza amashusho, ariko yohereza amajwi n’andi makuru y’inyongera mu gihe cy’uruhererekane rw’amashusho. HDMI 1.0 yemerera isaha ntarengwa ya TMDS ya 165 MHz (umurambararo wa buri murongo ni 4.95 Gbit/s), kimwe na DVI. Igena ubwoko bubiri bw’itumanaho ryitwa A-type na B-type, rikoresha pinouts zishingiye kuri single-link DVI-D na dual-link DVI-D connectors, nubwo B-type connector itigeze ikoreshwa mu bucuruzi ubwo aribwo bwose. HDMI 1.0 ikoresha 8 b/10 b encoding mu kohereza amashusho, iyiha bandwidth ya videwo ya 3.96 Gbit/s (1920 × 1080 cyangwa 1920 × 1080 60Hz) na 8-channel LPCM/192 kHz/24-bit audio. HDMI 1.0 isaba ubufasha kuri videwo ya RGB, kandi ishobora gushyigikira Y′CBCR 4:4:4 na 4:2:2 (bitegetswe niba igikoresho gishyigikira izindi interface za Y′CBCR). Ubujyakuzimu bw'amabara ya bpc 10 (30 bits/pixel) cyangwa 12 bpc (36 bits/pixel) bwemerera gukoresha ingero nto za 4:2:2, ariko ubujyakuzimu bw'amabara ya bpc 8 (24 bits/pixel) ni bwo bwemerewe iyo ukoresha RGB cyangwa Y′CBCR 4:4:4. Umwanya w'amabara wa Rec. 601 na Rec. 709 gusa ni wo ushyigikiwe. HDMI 1.0 yemerera gusa imiterere yihariye ya videwo, harimo imiterere yose yasobanuwe muri EIA/CEA-861-B n'indi miterere imwe yanditswe muri HDMI. Inkomoko/abakira HDMI bose bagomba kandi kuba bashobora kohereza/kwakira videwo ya DVI y'umwimerere kandi bagakurikiza byimazeyo amabwiriza ya DVI.
Verisiyo ya mbere ya HDMI, yasohotse mu Ukuboza 2002, ishobora kuvugwa ko yagenewe porogaramu za HD zose nka Blu-ray icyo gihe. Ikintu nyamukuru cyayo ni uguhuza uburyo bwo kohereza amashusho n'amajwi icyarimwe. Ugereranyije n'uburyo bwo kohereza amashusho kuri mudasobwa nka DVI na DisplayPort, ikwiriye cyane ibikoresho by'amajwi n'amashusho. HDMI 1.0 isanzwe ishyigikira DVD na Blu-ray videwo, ifite umuvuduko ntarengwa wa 4.95 Gbps, aho 3.96 Gbps ikoreshwa mu kohereza amashusho, ishobora gushyigikira 1080/60p cyangwa UXGA resolution; mu bijyanye n'amajwi, ishyigikira LPCM 24bit/192kHz ya channel 8, bivuze ko yamaze kugera ku majwi ya Hi-Res ya channel nyinshi. Mu kugereranya imiterere ya cable icyo gihe, yari ikomeye cyane.

HDMI 1.1

HDMI 1.1 yasohotse ku ya 20 Gicurasi 2004, yongeraho inkunga ya DVD-Audio.
Yatangijwe muri Gicurasi 2004 kandi yari irimo inkunga nshya ya DVD-Audio. DVD-Audio ibika umuziki wa PCM wa 16-bit/44.1kHz kugeza kuri 24-bit/192kHz kuri disiki za DVD. Mbere yari igamije gusimbura CD kimwe na SACD, ariko ikibabaje ni uko ubwo buryo bwombi bwananiwe gukundwa cyane.
HDMI 1.2
Inkunga ya SACD
Yasohotse muri Kanama 2005, yongeraho inkunga y'amajwi ya 1-bit, izwi kandi nka SACD audio streaming, kugeza kuri channel 8. DMI CEC yemerera remote control imwe kugenzura ibikoresho byose bihuye nayo, ibyo bikaba byoroshye cyane.
HDMI 1.2 yasohotse ku ya 8 Kanama 2005, yongeraho amajwi make kuri Super Audio CD, kugeza kuri chaneli 8. Kugira ngo HDMI ibe nziza kurushaho gukoreshwa ku bikoresho bya PC, verisiyo ya 1.2 yakuyeho icyifuzo cyo gukoresha gusa imiterere ishyigikiwe neza. Yongereye ubushobozi bw'abakora imiterere yihariye ku mutanga, bituma habaho ubushobozi bwo kuvugurura no kongera kuvugurura, bitagarukira gusa ku rutonde rw'imiterere ishyigikiwe. Byongeye kandi, yongereyeho inkunga isobanutse kuri imiterere mishya irimo 720p kuri 100 na 120Hz hamwe n'ibisabwa byo gushyigikira imiterere ya pixel, kugira ngo amasoko afite RGB yo mu gace (PC) gusa adasabwa gushyigikira umusaruro wa Y′CBCR.
