Nhanganyaya yekuchinja kweSpecial kubva paHDMI 1.0 kuenda kuHDMI 2.1 (Chikamu 1)

Kubva pakaburitswa mutambi wekutanga weBlu-ray pasi rose, Samsung BD-P1000, muna 2006, uyo wakashandisa HDMI, ruzhinji rwevatambi veBlu-ray nemidziyo yekutamba yakazara HD yave neHDMI. Kubva ipapo, HDMI yave isingamisiki uye yave ichitonga indasitiri yetambo kwemakore mazhinji, ichisanganisira zvikamu zvekutumira maaudio nemavhidhiyo zvevatengi neindasitiri.

Kushanduka kweshanduro dzeHDMI

1.4 na2.0 ndidzo dzinonyanya kuzivikanwa

2.0a inotsigira 4K HDR
HDMI 1.0
Inotsigira Blu-ray uye Full HD 1080/60Hz
HDMI 1.0 yakaburitswa musi wa9 Zvita, 2002. I-single-line digital audio/video connector interface. Magadzirirwo elink akavakirwa paDVI uye anoshandisa format imwechete yekutumira mavhidhiyo, asi anotumira odhiyo nedzimwe data rekubatsira panguva yekubuda kwevhidhiyo. HDMI 1.0 inobvumira wachi yepamusoro yeTMDS ye165 MHz (bandwidth yelink yega yega i4.95 Gbit/s), yakafanana neDVI. Inotsanangura mhando mbiri dzeconnectors dzinonzi A-type neB-type, dzinoshandisa pinouts zvichibva pa single-link DVI-D uye dual-link DVI-D connectors, kunyangwe B-type connector isati yamboshandiswa mune chero chigadzirwa chekutengesa. HDMI 1.0 inoshandisa 8 b/10 b encoding yekutumira mavhidhiyo, ichiipa vhidhiyo bandwidth ye3.96 Gbit/s (1920×1080 kana 1920×1080 60Hz) uye 8-channel LPCM/192 kHz/24-bit audio. HDMI 1.0 inoda rutsigiro rwevhidhiyo yeRGB, uye inogona kutsigira Y′CBCR 4:4:4 uye 4:2:2 (inomanikidzwa kana mudziyo uchitsigira mamwe ma interfaces eY′CBCR). Kudzika kwemavara e10 bpc (30 bits/pixel) kana 12 bpc (36 bits/pixel) kunobvumira kushandiswa kwe4:2:2 subsampling, asi kudzika kwemavara e8 bpc (24 bits/pixel) chete ndiko kunobvumirwa kana uchishandisa RGB kana Y′CBCR 4:4:4. Nzvimbo dzemavara dzeRec. 601 neRec. 709 chete ndidzo dzinotsigirwa. HDMI 1.0 inongobvumira mafomati chaiwo evhidhiyo akatsanangurwa kare, kusanganisira mafomati ese akatsanangurwa muEIA/CEA-861-B nemamwe mafomati akanyorwa muHDMI specification. Masource/receivers ese eHDMI anofanirawo kukwanisa kutumira/kugamuchira vhidhiyo yeDVI yemota uye kutevedzera zvizere specification yeDVI.
Shanduro yekutanga yeHDMI, yakaburitswa muna Zvita 2002, inogona kunzi yakagadzirirwa software yakazara yeHD senge Blu-ray panguva iyoyo. Chinhu chikuru chayo ndechekubatanidzwa kwekutumira mavhidhiyo neaudio panguva imwe chete. Kana ichienzaniswa nema interfaces ekutumira mavhidhiyo chaiwo pamakomputa akadai seDVI neDisplayPort, inonyanya kukodzera michina yeaudio-visual. HDMI 1.0 inototsigira DVD neBlu-ray vhidhiyo, ine bandwidth yepamusoro ye4.95 Gbps, iyo 3.96 Gbps inoshandiswa kutumira mavhidhiyo, inokwanisa kutsigira 1080/60p kana UXGA resolution; maererano neaudio, inotsigira 8-channel LPCM 24bit/192kHz, zvichireva kuti yatosvika multi-channel Hi-Res audio. Mukuenzanisa tambo dzemagetsi panguva iyoyo, yakanga yakasimba kwazvo.

HDMI 1.1

HDMI 1.1 yakaburitswa musi wa20 Chivabvu, 2004, uye yakawedzera rutsigiro rweDVD-Audio.
Yakatangwa muna Chivabvu 2004 uye yaisanganisira rutsigiro rutsva rweDVD-Audio. DVD-Audio inochengetedza mimhanzi yePCM ye16-bit/44.1kHz kusvika 24-bit/192kHz pamaDVD discs. Pakutanga yaida kutsiva CD zvakafanana neSACD, asi zvinosuwisa kuti mafomati ese ari maviri haana kufarirwa zvakanyanya.
HDMI 1.2
Rutsigiro rweSACD
Yakaburitswa muna Nyamavhuvhu 2005, ichiwedzera rutsigiro rwe1-bit audio, inozivikanwawo seSACD audio streaming, kusvika kumachaneli masere. DMI CEC inobvumira remote control imwe chete kudzora zvishandiso zvese zvinoenderana nayo, izvo zviri nyore kwazvo.
HDMI 1.2 yakaburitswa musi wa8 Nyamavhuvhu, 2005, uye yakawedzera sarudzo yekuteerera yeSuper Audio CD, inosvika machaneli masere. Kuti HDMI ive yakakodzera kushandiswa pamidziyo yePC, vhezheni 1.2 yakabvisawo chinodiwa chekushandisa mafomati anotsigirwa zvakajeka chete. Yakawedzera kugona kwevagadziri kugadzira mafomati chaiwo kune mutengesi, zvichibvumira chero resolution uye refresh rate, kwete kungogumira pane runyorwa rwakafanotaurwa rwemafomati anotsigirwa. Pamusoro pezvo, yakawedzera rutsigiro rwakajeka kune mamwe mafomati matsva anosanganisira 720p pa100 ne120Hz uye zvinodiwa zvekutsigira mafomati epixel akasununguka, kuitira kuti masosi ane maRGB emunharaunda (PC) chete asadiwe kutsigira mabudiro eY′CBCR.
