Litlhahiso tse tharo tsa HDMI 2.2 ho Setifikeiti sa ULTRA96
Lithapo tsa HDMI 2.2 li tlameha ho tšoauoa ka mantsoe a reng “ULTRA96″, e leng se bontšang hore li tšehetsa bandwidth e fihlang ho 96Gbps.
Letšoao lena le tiisa hore moreki o reka sehlahisoa se finyellang litlhoko tsa bona, kaha mohala oa hona joale oa HDMI 2.1 o na le bandwidth e phahameng ea 48 Gbps feela. Seboka sa HDMI se tla leka bolelele bo bong le bo bong ba cable ho netefatsa hore ho latela melao, 'me letšoao le tlameha ho kenngoa ho cable.
HDMI 2.2 e ka fetisa litaba ka qeto e phahameng ea 12K ho 120fps kapa 16K ho 60fps ho lisebelisoa tse tšehetsoeng, hape e tšehetsa liforomo tse sa lahleheng tsa mebala e feletseng, tse kang 8K HDMI resolution ho 60 fps / 4: 4: 4 le 4K resolution ho 240 fps / 4: 4: 4, ka 'mala oa 1-bit oa 10-bit le botebo ba 10-bit.
Ho phaella moo, HDMI 2.2 e na le karolo e ncha e bitsoang Delay Indication Protocol (LIP), e ka ntlafatsang ho lumellana ha molumo le video. Sena se tla ba molemo haholo bakeng sa tlhophiso e rarahaneng ea sistimi ho kenyelletsa le li-audio-video tse amohelang kapa libui tse potolohileng.
Ka Forum ea HDMI e lokollang ka molao litlhaloso tse feletseng tsa HDMI version 2.2, lithapo tse tiisitsoeng tse amanang le lisebelisoa tse lumellanang li lebelletsoe ho qalisoa haufinyane.
Tlhaloso ea HDMI 2.2 Litlhaloso le Liphephetso tsa Teko le Setifikeiti
Lefapheng la phetisetso ea li-audio le video tsa digital, HDMI (High-Definition Multimedia Interface) e na le boemo bo ka sehloohong. Ho ea ka lintlha tse lokollotsoeng ke HDMI Licensing Administrator (HDMI LA) kopanong ea CES 2025, palo ea lisebelisoa tse tšehetsang HDMI li feta li-unit tse limilione tse 900 ka 2024, 'me kakaretso ea thomello ea thepa e fihlile ho li-unit tse limilione tse likete tse 1.4. Ha 'maraka o batla ho etsa liqeto tse phahameng, litefiso tse phahameng tsa ho khatholla, le liphihlelo tse tebileng li ntse li eketseha, joalo ka phatlalatso ea li-TV tsa lipapali tsa moloko o latelang ka 4K@240Hz le lits'ebetso tsa AR/VR, Foramo ea HDMI e phatlalalitse ka molao litlhaloso tsa HDMI 2.2. Se latelang ke tlhaloso ea mekhoa e meraro ea mantlha ea theknoloji ea HDMI 2.2. Liphetoho tse tharo tsa motheo tsa theknoloji ea HDMI 2.2 Ho ea ka ho lokolloa ke Forum ea HDMI, ntlafatso ea HDMI 2.2 e shebane haholo le mesebetsi e meraro ea mantlha, e ikemiselitseng ho finyella litlhoko tsa nts'etsopele ea theknoloji ea li-audio-visual lilemong tse leshome tse latelang: 1. Bandwidth habeli: Ho fallela ho 96Gbps FRL thekenoloji. Ntlafatso e hlahelletseng ka ho fetesisa ke ho imena habeli ka kotloloho ho bandwidth e phahameng ho tloha HDMI 2.1's 48Gbps ho isa 96Gbps. Ho tlola hona ho finyelloa ka theknoloji e ncha ea "Fixed Rate Link (FRL)". Keketseho ena e makatsang ea bandwidth e tla notlolla bokhoni ba pono-mantsoe bo e-so ka bo bonoa, ho kenyelletsa: (1) Ts'ehetso ea litšoantšo tse hlakileng ntle le khatello: E khona ho ts'ehetsa 4K@240Hz, 8K HDMI@120Hz, le mefuta e meng ea litšoantšo tsa boleng bo holimo le tse holimo. (2) Ho boloka sebaka bakeng sa bokamoso: Ka theknoloji ea compression ea video (DSC), e ka tšehetsa lintlha tse makatsang tse kang 8K HDMI@240Hz, 10K@120Hz, esita le 12K@120Hz. (3) Ho kopana le likopo tsa litsebi le tsa khoebo: Ho fana ka motheo o tiileng oa likopo tse hlokang phetisetso e kholo ea data, joalo ka AR / VR / MR, litšoantšo tsa bongaka, le liphanele tse kholo tsa dijithale. 2. Lenaneo le lecha la Ultra96 HDMI® Cable le Setifikeiti; Ho tsamaisa sephethephethe se seholo sa ho fihla ho 96Gbps, litlhaloso tsa HDMI 2.2 li kenyelletsa "Ultra96 HDMI® Cable" e ncha. Cable ena e tla fetoha karolo ea HDMI Ultra Certification Program, ho bolelang hore mofuta o mong le o mong o fapaneng oa thapo le bolelele ba thapo (joalo ka Slim HDMI, OD 3.0mm HDMI, Right Angle HDMI) li tlameha ho etsa liteko tse matla le setifikeiti pele li ka rekisoa. HDMI LA e ile ea hatisa sebokeng bohlokoa ba ho lumellana le phepelo ea thepa, ho kenyelletsa le ho senya lihlahisoa tse sa lumelloeng le tse sa lumellaneng. Sena se bolela hore setifikeiti sa semmuso se tla ba bohlokoa ho feta neng kapa neng. Ts'ebetso ena e netefatsa hore bareki ba ka reka lihlahisoa tse finyellang litlhoko le ho tsamaea ka bolokolohi 'marakeng oa lefatše. 3. Mopholosi oa khokahano ea audio-visual: Latency Indication Protocol (LIP) e etsa hore ho sisinyeha ha molomo ho se tsamaisane le molumo, e leng ntho e nyarosang ho batho ba bangata ba theater ea lapeng kapa basebelisi ba rarahaneng ba audio-visual system. Haholo-holo maemong ao lets'oao le fetang lisebelisoa tse ngata (tse kang papali ea papali -> AVR -> TV) ka mokhoa oa "multiple-hop", bothata ba ho lieha bo ba matla le ho feta. HDMI 2.2 e hlahisa mofuta o mocha oa Latency Indication Protocol (LIP), e nolofalletsang sesebelisoa sa mohloli le sesebelisoa sa pontšo ho buisana ka maemo a bona a ho lieha, ho lumella tsamaiso ho hokahanya molumo le video ka bohlale le ka katleho, ho ntlafatsa haholo phihlelo ea mosebedisi. HDMI 1.4 vs 2.1 vs 2.2 Specification Papiso Ho utloisisa hamolemo ntlafatso ea theknoloji ea HDMI 2.2, tafole e latelang ea papiso e hlophisitsoe ka ho khetheha:
Mathata a Teko le Setifikeiti sa HDMI 2.2 Ho lokolloa ha HDMI 2.2 ho tla tlisa mathata a 'maloa a macha maemong a fapaneng:
Teko ea 1. Physical Layer (PHY): Phephetso e feteletseng e ka har'a pontšo ea botšepehi (Signal Integrity). Ka bandwidth ea 96 Gbps, bandwidth e phahameng ka ho fetesisa e beha litlhoko tse thata tseo ho seng mohla li kileng tsa e-ba teng mabapi le botšepehi ba matšoao. Nakong ea tlhahlobo, re hloka lisebelisoa tse nepahetseng haholoanyane ho sekaseka matšoao a bohlokoa joalo ka litšoantšo tsa mahlo, jitter, tahlehelo ea ho kenya, le crosstalk ho netefatsa botsitso ba lets'oao nakong ea phetisetso ea lebelo le holimo. Lithapo le likhokahano: Lithapo tse ncha tsa Ultra96 (ho kenyeletsoa Flexible HDMI, MINI HDMI Cable, MICRO HDMI Cable) li tlameha ho feta litekanyetso tse thata tsa tlhahlobo, mme ts'ebetso ea tsona ka maqhubu a phahameng e tla ba sepheo sa setifikeiti. Setsi sa tlhahlobo se lumelletsoeng sa molao (ATC) se tla sebelisana haufi-ufi le Foramo ea HDMI ho theha tharollo e felletseng ea tlhahlobo.
2. Teko ea Layer (Protocol): Ho rarahana ha tlhahlobo ea protocol ho eketsehile haholo. Netefatso ea protocol ea LIP: The Delay Indication Protocol (LIP) ke karolo e ncha e hlokang lisebelisoa tse khethehileng tsa tlhahlobo ea protocol ho etsisa maemo a fapaneng a lisebelisoa tsa multi-hop le ho netefatsa bonnete ba puisano ea protocol lipakeng tsa mehloli, li-relay le lisebelisoa tsa pontšo. Likopano tse kholo tsa sebopeho: HDMI 2.2 e ts'ehetsa motsoako o moholo haholo oa liqeto, litefiso tsa ho khatholla, sampole ea chroma le botebo ba mebala. Nakong ea tlhahlobo, hoa hlokahala ho etsa bonnete ba hore sehlahisoa se ka buisana ka nepo le ho bonts'a ka mefuta e fapaneng (e kang 144Hz HDMI, 8K HDMI), haholo-holo ha khatello ea DSC e nolofalitsoe, e tla eketsa haholo ho rarahana le nako ea teko.
Phatlalatso ea HDMI 2.2's e Tšoaea Ketsahalo ea Bohlokoa ho Tsoelo-pele ea Theknoloji ea Audio-Visual Interface. Ha se feela keketseho ea li-bandwidth, empa hape e emela tšimoloho ea tikoloho e ncha e ka sebetsanang le maemo a holimo le liphihlelo tse sebetsanang le ho feta lilemong tse leshome tse tlang. Le hoja ho amoheloa ho pharaletseng ha lihlahisoa tsa HDMI 2.2 ho ntse ho le nako, ntlafatso ea theknoloji ha e e-s'o khaotse. Lithapo tsa Ultra96 (ho kenyeletsoa Slim HDMI, Right Angle HDMI, MICRO HDMI Cable) li lebelletsoe ho kena 'marakeng karolong ea boraro kapa ea bone ea 2025. A re amoheleng ka kopanelo ho fihla ha nako e ncha ea boleng ba litšoantšo tsa ultra-high le HDMI 2.2.
