Intshayelelo kwiinguqu zeNkcazelo ukusuka kwi-HDMI 1.0 ukuya kwi-HDMI 2.1 (Icandelo 1)

Ukususela ekukhutshweni kwesidlali sokuqala seBlu-ray kwihlabathi, iSamsung BD-P1000, ngo-2006, esasebenzisa iHDMI, uninzi lwabadlali beBlu-ray kunye nezixhobo zokudlala zeFull HD zixhotyiswe ngeHDMI. Ukususela ngoko, iHDMI ibingenakuthintelwa kwaye ibilawula ishishini leentambo kangangeminyaka emininzi, igubungela amacandelo osasazo lweaudio kunye nevidiyo kubathengi nakwimizi-mveliso.

Utshintsho kwiinguqulelo zeHDMI

I-1.4 kunye ne-2.0 zezona zixhaphakileyo

I-2.0a ixhasa i-4K HDR
I-HDMI 1.0
Ixhasa iBlu-ray kunye neFull HD 1080/60Hz
I-HDMI 1.0 yakhutshwa ngoDisemba 9, 2002. Yi-interface yedijithali yeaudio/video. Uyilo lwekhonkco lusekelwe kwi-DVI kwaye lusebenzisa ifomathi efanayo yokudlulisa ividiyo, kodwa ludlulisela iaudio kunye nedatha encedisayo ngexesha lokusasazwa kwevidiyo. I-HDMI 1.0 ivumela iwotshi ye-TMDS ephezulu ye-165 MHz (i-bandwidth yekhonkco ngalinye yi-4.95 Gbit/s), efanayo ne-DVI. Ichaza iintlobo ezimbini zezixhumanisi ezibizwa ngokuba yi-A-type kunye ne-B-type, ezisebenzisa ii-pinouts ezisekelwe kwi-single-link DVI-D kunye ne-dual-link DVI-D connectors, nangona i-B-type connector ingazange isetyenziswe nakweyiphi na imveliso yorhwebo. I-HDMI 1.0 isebenzisa i-8 b/10 b encoding yokudlulisa ividiyo, iyinika i-bandwidth yevidiyo ye-3.96 Gbit/s (1920×1080 okanye 1920×1080 60Hz) kunye ne-8-channel LPCM/192 kHz/24-bit audio. I-HDMI 1.0 ifuna inkxaso yevidiyo ye-RGB, kwaye ixhasa ngokukodwa i-Y′CBCR 4:4:4 kunye ne-4:2:2 (inyanzelekile ukuba isixhobo sixhasa ezinye ii-interface ze-Y′CBCR). Ubunzulu bombala obuyi-10 bpc (30 bits/pixel) okanye i-12 bpc (36 bits/pixel) buvumela ukusetyenziswa kwesampulu encinci ye-4:2:2, kodwa ububanzi bombala obuyi-8 bpc (24 bits/pixel) buvumelekile xa usebenzisa i-RGB okanye i-Y′CBCR 4:4:4. Kuphela zizithuba zombala ze-Rec. 601 kunye ne-Rec. 709 ezixhaswayo. I-HDMI 1.0 ivumela kuphela iifomathi ezithile zevidiyo ezichazwe kwangaphambili, kuquka zonke iifomathi ezichazwe kwi-EIA/CEA-861-B kunye nezinye iifomathi ezidweliswe kwinkcazo ye-HDMI. Zonke imithombo/abamkeli be-HDMI kufuneka bakwazi ukuthumela/ukufumana ividiyo ye-DVI ye-single-link yendalo kwaye bathobele ngokupheleleyo inkcazo ye-DVI.
Inguqulelo yokuqala ye-HDMI, eyakhutshwa ngoDisemba ka-2002, kunokuthiwa yenzelwe ngokukodwa isoftware epheleleyo ye-HD efana ne-Blu-ray ngelo xesha. Eyona nto iphambili kuyo kukudibanisa ukuhanjiswa kwevidiyo kunye nesandi ngaxeshanye. Xa kuthelekiswa neendawo zokusasaza ividiyo ezicocekileyo kwiikhompyutha ezifana ne-DVI kunye ne-DisplayPort, ifanelekile ngakumbi kwizixhobo zesandi-ne-visual. I-HDMI 1.0 sele ixhasa ividiyo ye-DVD kunye ne-Blu-ray, ene-bandwidth ephezulu ye-4.95 Gbps, apho i-3.96 Gbps isetyenziselwa ukudlulisa imijelo yevidiyo, ekwaziyo ukuxhasa isisombululo se-1080/60p okanye i-UXGA; ngokwesandi, ixhasa i-8-channel LPCM 24bit/192kHz, oko kuthetha ukuba sele ifikelele kwi-multi-channel Hi-Res audio. Xa kuthelekiswa ne-cable specifications ngelo xesha, yayinamandla kakhulu.

I-HDMI 1.1

I-HDMI 1.1 yakhutshwa ngoMeyi 20, 2004, kwaye yongeza inkxaso kwi-DVD-Audio.
Yaqaliswa ngoMeyi 2004 kwaye yayinenkxaso entsha yeDVD-Audio. IDVD-Audio igcina umculo wePCM osuka kwi-16-bit/44.1kHz ukuya kwi-24-bit/192kHz kwiidiski zeDVD. Ekuqaleni yayijoliswe ekubeni ibe yindlalifa yeCD ngokufanayo neSACD, kodwa ngelishwa, zombini ezi fomathi azizange zifumane ukuthandwa ngokubanzi.
I-HDMI 1.2
Inkxaso ye-SACD
Yakhutshwa ngo-Agasti 2005, yongeza inkxaso yesandi se-1-bit, esaziwa ngokuba yi-SACD audio streaming, ukuya kuthi ga kwiitshaneli ezi-8. I-DMI CEC ivumela ulawulo olukude olunye ukulawula zonke izixhobo ezihambelanayo, nto leyo elula kakhulu.
I-HDMI 1.2 yakhululwa nge-8 ka-Agasti 2005, yaza yongeza ukhetho oluncinci lwesandi kwi-Super Audio CD, ukuya kuthi ga kwiitshaneli ezi-8. Ukuze i-HDMI ifaneleke ngakumbi ukusetyenziswa kwizixhobo zePC, inguqulelo 1.2 ikwasuse imfuneko yokusebenzisa iifomathi ezixhaswa ngokucacileyo kuphela. Yonyusa amandla abavelisi okwenza iifomathi ezithile kumthengisi, ivumela naluphi na ulungiso kunye nesantya sokuhlaziya, kungaphelelanga kuluhlu oluchazwe kwangaphambili lweefomathi ezixhaswayo. Ukongeza, yongeza inkxaso ecacileyo kwezinye iifomathi ezintsha kuquka i-720p kwi-100 kunye ne-120Hz kunye neemfuno zenkxaso yefomathi ye-pixel ekhululekileyo, ukuze imithombo enemveliso ye-RGB yasekuhlaleni (i-PC) kuphela ingadingeki ukuxhasa imveliso ye-Y′CBCR.
