Kubudirira Kutatu kweHDMI 2.2 muULTRA96 Certification

Kubudirira Kutatu kweHDMI 2.2 muULTRA96 Certification

Mawaya eHDMI 2.2 anofanira kunge akanyorwa mashoko ekuti “ULTRA96″, zvichiratidza kuti anotsigira bandwidth inosvika 96Gbps.

Chiremba ichi chinovimbisa kuti mutengi anotenga chigadzirwa chinoenderana nezvinodiwa zvake, sezvo tambo yeHDMI 2.1 iripo ine bandwidth yepamusoro ye48 Gbps chete. HDMI Forum ichaedza kureba kwetambo yega yega kuti ive nechokwadi chekuti inotevedzera zvinodiwa, uye chiremba chinofanira kunamirwa patambo.
HDMI 2.2 inogona kutumira zvirimo zvine resolution yepamusoro ye12K pa120 fps kana 16K pa60 fps kumidziyo inotsigirwa, uye inotsigirawo mafomati emavara akazara asina kurasikirwa, akadai se8K HDMI resolution pa60 fps / 4:4:4 uye 4K resolution pa240 fps / 4:4:4, ine kudzika kwemavara e10-bit ne12-bit.
Pamusoro pezvo, HDMI 2.2 ine chinhu chitsva chinonzi Delay Indication Protocol (LIP), chinogona kuvandudza kuenderana kwemaaudio-video. Izvi zvichabatsira zvikuru kune mamwe magadzirirwo akaomarara esystem anosanganisira maaudio-video receivers kana maspika akakomberedza.

Nekuda kwekuburitswa kwemutemo kweHDMI Forum zvizere maererano neHDMI version 2.2, tambo dzakasimbiswa pamwe chete nemidziyo inoenderana nayo zvinotarisirwa kuvhurwa munguva pfupi iri kutevera.
Kududzirwa kweHDMI 2.2 Magadzirirwo uye Matambudziko eKuyedzwa neChitupa
Munyaya yekutumira ma audio nemavhidhiyo edhijitari, HDMI (High-Definition Multimedia Interface) ndiyo ine chinzvimbo chepamusoro. Zvichienderana nedata rakaburitswa neHDMI Licensing Administrator (HDMI LA) pamusangano weCES 2025, huwandu hwemidziyo inotsigira HDMI hwakapfuura mayuniti emamiriyoni mazana mapfumbamwe muna 2024, uye huwandu hwese hwekutumira hwasvika mabhiriyoni zana nemazana mana ezviuru. Sezvo kudiwa kwemusika kwe resolutions dzakakwirira, mitengo yakakwira yekuvandudza, uye ruzivo rwakawanda rwuri kuramba ruchikwira, senge kufarirwa kwemaTV emitambo echizvarwa chinotevera ane 4K@240Hz uye AR/VR applications, HDMI Forum yakazivisa zviri pamutemo HDMI 2.2 specification. Inotevera idudziro yekuvandudzwa kwehunyanzvi hutatu hukuru hweHDMI 2.2. Kuvandudzwa kwehunyanzvi hutatu hukuru hweHDMI 2.2 Zvichienderana nekuburitswa kweHDMI Forum, kuvandudzwa kweHDMI 2.2 kunonyanya kutarisa pamabasa matatu makuru, nechinangwa chekusangana nezvinodiwa zvekuvandudza tekinoroji yeaudio-visual mumakore gumi anotevera: 1. Kuwedzerwa kwebandwidth: Kufambira mberi kune tekinoroji ye96Gbps FRL. Kuvandudzwa kunonyanya kuzivikanwa ndiko kuwedzera kaviri kwakananga kwebandwidth yepamusoro kubva paHDMI 2.1's 48Gbps kusvika ku96Gbps. Kufambira mberi uku kunowanikwa kuburikidza netekinoroji itsva ye "Fixed Rate Link (FRL)". Kuwedzera uku kunoshamisa kwebandwidth kuchavhura kugona kwekuona-kunzwa kusati kwamboitika, kusanganisira: (1) Kutsigira mifananidzo yepamusoro isina kudzvanywa: Inokwanisa kutsigira 4K@240Hz, 8K HDMI@120Hz, uye mamwe mafomati emifananidzo emhando yepamusoro uye yepamusoro-soro. (2) Kuchengetedza nzvimbo yenguva yemberi: Kuburikidza netekinoroji yekumanikidza vhidhiyo (DSC), inogona kutsigira maficha anoshamisa akadai se8K HDMI@240Hz, 10K@120Hz, uye kunyange 12K@120Hz. (3) Kusangana nemashandisirwo ehunyanzvi uye ekutengeserana: Kupa hwaro hwakasimba hwemashandisirwo anoda kutumira data rakakura, senge AR/VR/MR, medical imaging, uye mapaneru makuru edhijitari. 2. Chirongwa Chitsva cheUltra96 HDMI® Cable and Certification; Kuti kutakura vanhu vakawanda kusvika ku96Gbps, HDMI 2.2 specification inosanganisira "Ultra96 HDMI® Cable" itsva. Iyi tambo ichave chikamu cheHDMI Ultra Certification Program, zvichireva kuti mhando imwe neimwe yakasiyana uye kureba kwetambo (senge Slim HDMI, OD 3.0mm HDMI, Right Angle HDMI) inofanira kuongororwa zvakasimba uye kupihwa chitupa isati yatengeswa. HDMI LA yakasimbisa pamusangano kukosha kwekutevedzera mitemo yekutengeserana, kusanganisira kudzvanywa kwezvinhu zvisingatenderwe uye zvisingatevedzere mitemo. Izvi zvinoreva kuti chitupa chepamutemo chichava chakakosha kupfuura kare. Danho iri rinoita kuti vatengi vagone kutenga zvigadzirwa zvinoenderana nezvinodiwa uye zvinogona kufamba zvakasununguka mumusika wepasi rose. 3. Muponesi wekubatanidza audio-visual: Latency Indication Protocol (LIP) inoita kuti kufamba kwemiromo kusaenderane neruzha, izvo zvinonetsa vazhinji vanoshandisa home theatre kana audio-visual system yakaoma. Kunyanya mumamiriro ezvinhu apo chiratidzo chinopfuura nepamidziyo yakawanda (senge game console -> AVR -> TV) nenzira ye "multiple-hop", dambudziko rekunonoka rinova rakanyanya kuoma. HDMI 2.2 inounza Latency Indication Protocol itsva (LIP), iyo inogonesa mudziyo wekutanga nemudziyo wekuratidza kutaurirana mamiriro avo ekunonoka, zvichibvumira sisitimu kuwiriranisa odhiyo nevhidhiyo zvine hungwaru uye zvinobudirira, zvichivandudza zvakanyanya ruzivo rwemushandisi. HDMI 1.4 vs 2.1 vs 2.2 Kuenzanisa Magadzirirwo Kuti unzwisise zviri nani hunyanzvi hwetekinoroji hweHDMI 2.2, tafura yekufananidza inotevera yakagadzirwa zvakanyanya:

Matambudziko eKuedzwa neKupihwa Chitupa kweHDMI 2.2 Kuburitswa kweHDMI 2.2 kuchaunza matambudziko matsva akasiyana siyana:

1. Kuedzwa kwePhysical Layer (PHY): Dambudziko guru riri mukusimbaradzwa kwechiratidzo (Signal Integrity). Nebandwidth ye96 Gbps, bandwidth yepamusoro-soro inoisa zvinodiwa zvakanyanya pakusimbaradzwa kwechiratidzo. Munguva yekuedza, tinoda zvishandiso zvakanyatsojeka kuti tiongorore zviratidzo zvakakosha zvakaita semadhayagiramu emaziso, jitter, insertion loss, uye crosstalk kuti tive nechokwadi chekuti chiratidzo chakasimba panguva yekutumira nekukurumidza. Matambo nezvinobatanidza: Matambo matsva eUltra96 (kusanganisira Flexible HDMI, MINI HDMI Cable, MICRO HDMI Cable) anofanira kupasa zviyero zvekuyedza zvakasimba, uye mashandiro awo pamafrequencies akakwira ndiwo achava chinangwa chechitupa. Nzvimbo yekuyedza yakabvumidzwa yepamutemo (ATC) ichashanda pamwe chete neHDMI Forum kuti vagadzire mhinduro yakakwana yekuyedza.
2. Kuedzwa kweProtocol Layer (Protocol): Kuomarara kwekuyedzwa kweprotocol kwawedzera zvakanyanya. Kusimbiswa kweprotocol yeLIP: Iyo Delay Indication Protocol (LIP) chinhu chitsva chinoda zvishandiso zvekuongorora protocol zvakanongedzera kuti zvitevedzere mamiriro akasiyana-siyana emidziyo ye multi-hop uye kusimbisa kururama kwekutaurirana kweprotocol pakati pemasosi, relay, uye zvishandiso zve display. Kusanganiswa kukuru kwefomati: HDMI 2.2 inotsigira musanganiswa wakakura kwazvo we resolutions, refresh rates, chroma sampling, uye kudzika kwemavara. Panguva yekuyedza, zvakakosha kuve nechokwadi chekuti chigadzirwa chinogona kutaurirana nemazvo uye kuratidza mumisanganiswa yakasiyana-siyana (yakadai se144Hz HDMI, 8K HDMI), kunyanya kana DSC compression yagoneswa, izvo zvichawedzera zvakanyanya kuomarara nenguva yekuyedza.
Kuburitswa kweHDMI 2.2 Kunoratidza Kukosha Kwakakosha Mukuvandudzwa kweTekinoroji yeAudio-Visual Interface. Hakusi kungowedzera bandwidth chete, asi kunomiririrawo kutanga kwemamiriro matsva ekunze anogona kugadzirisa mhando yepamusoro uye zviitiko zvinodyidzana mumakore gumi anotevera. Kunyangwe kushandiswa kwakapararira kwezvigadzirwa zveHDMI 2.2 kuchiri kure, kuvandudzwa kwetekinoroji hakuna kumbomira. Matambo eUltra96 (kusanganisira Slim HDMI, Right Angle HDMI, MICRO HDMI Cable) anotarisirwa kupinda mumusika muchikamu chechitatu kana chechina cha2025. Ngatigamuchirei pamwe chete kusvika kwenguva itsva yemhando yepamusoro yemifananidzo neHDMI 2.2.
