Codec e hlahisitsoe ka 2018 e ne e tšehetsoa ke libapali tse kholo 'marakeng oa ho phallela. Barekisi ba thepa ea thepa ba netefalitse tšehetso bakeng sa codec e ncha, 'me li-endpoints tse nang le AV1 hardware decoding li lokela ho ba teng mafelong a selemo. Khahlanong le semelo sena, lits'oants'o tsa patent tse nang le litlhoko tsa lichelete li ile tsa sebetsa haholoanyane.
Codec ea video mohloli o bulehileng o entsoe ho tloha 2015 ke baenjiniere ba lik'hamphani tse 'maloa, ho akarelletsa le Amazon, BBC, Netflix, Hulu le ba bang, ba entseng Alliance for Open Media (AOMedia). Theknoloji e ncha e reretsoe haholo-holo ho phallela video ka liqeto tse phahameng haholo (4K le holimo), e nang le mebala e atolositsoeng ea mebala le mahlale a fapaneng a HDR. Har'a likarolo tsa mantlha tsa codec, AOMedia e supa algorithm ea compression ha e bapisoa le mekhoa e teng, litlhoko tsa khomphutha tsa Hardware tse lebelletsoeng esale pele, le ho feto-fetoha ha maemo ho hoholo le scalability.
Likhamphani tsena tse nang le lits'ebeletso tsa tsona tsa ho phallela li hloka li-codec tse sebetsang joalo ka moea. Taba ea pele, AV1 e fokotsa litlhoko tsa bandwidth ea khokahano ea Marang-rang maemong a setsi sa data (DPC) le maemong a bafani le basebelisi ba ho qetela. Taba ea bobeli, ts'ebeliso ea Amazon Studios ea filimi ea 65mm le lik'hamera tsa IMAX MSM 9802 (tseo ho leng thata ho li hira) le RED Monstro bakeng sa filimi ea Aeronafta () e bontša hore k'hamphani e lokisetsa nako ea post-4K, moo li-codec tsa morao-rao li ke keng tsa bonahala li sebetsa hantle.
Ha e le li-decoder tsa software, li teng hajoale lik'hamphani tse ngata tse kenyeletsang Cisco, Google, Netflix, Microsoft le Mozilla. Ka nako e ts'oanang, decoding ea software, joalo ka molao, e lula e bolela tšebeliso e eketsehileng ea matla le tšebeliso e fokolang haholo. Ka hona, ho tla ba monate ho bona ts'ehetso bakeng sa decoding ea hardware.
Chips & Media e bile e 'ngoe ea tsa pele tsa ho hlahisa AV1 decoder ka Mphalane selemong se fetileng. Sesebelisoa sa video ke thepa ea bohlale e nang le laesense (e kopantsoeng boemong ba RTL) e ka kengoang ho system-on-chip (SoC) ho sebelisoa libese tsa ka hare tsa ARM AMBA 3 APB le ARM AMBA3 AXI. Decoder ena e ts'ehetsa AV1 codec level 5.1, bitrate ea boholo ba 50 Mbps, botebo ba mebala ba 8 kapa 10 bits, le 4:2:0 mebala ea subsampling. Tokiso ea Wave 510A's single-core 450MHz e ka sebelisoa ho khetholla melapo ea 4K ka 60Hz (4Kp60) ha dual-core configure e ka sebelisoa ho khetholla melapo ea 4Kp120 kapa 8Kp60.
Ntle le Chips & Media, lik'hamphani tse ling tse 'maloa li fana ka li-processor tsa video tse nang le tumello ka tšehetso ea AV1. Ka mohlala, E ts'ehetsa ka bobeli AV1 le mefuta e meng e tsebahalang ho kenyelletsa H.264, H.265 (HEVC), VP9 le JPEG. Li boetse li tšehetsa 4:2:0 le 4:2:2 chroma subsampling bakeng sa lisebelisoa tsa bareki le tsa litsebi. Ka nako e ts'oanang, Allegro o re litharollo tsena li fuoe laesense ke bafani ba lisebelisoa tsa boemo ba pele 'me li tla sebelisoa lisebelisoa tsa ho qetela tse tla lokolloa pele selemo se fela.
Ntle le li-processor tsa video tse nang le tumello, bahlahisi ba 'maloa ba phatlalalitse li-system-on-chip tse seng li entsoe ka tšehetso ea AV1 bakeng sa li-TV, mabokose a behiloeng holimo, libapali le lisebelisoa tse ling tse tšoanang. Amlogic e hlahella har'a ba bang ho tšehetsa liqeto ho fihla ho 8Kp60, Broadcom ka tšehetso ea 4Kp60, Realtek (4Kp60) le (8Kp60). Ntle le moo, LG ea moloko oa boraro α9 SoCs, e matlafatsang li-TV tsa 8 2020K tsa k'hamphani, le eona e ts'ehetsa AV1. Ntle le moo, MediaTek e phatlalalitse Dimensity 1000 mobile-on-chip e nang le AV1 hardware decoder.
Joalo ka ha u bona, ts'ehetso ea ho hlakisa lisebelisoa tsa AV1 ho tsoa ho baetsi ba li-processor le li-chips tse nang le tumello e ntse e le bonolo haholo. Leha ho le joalo, ho fanoe ka tšehetso ea codec e ncha ho tsoa ho lik'hamphani tse ngata tsa theknoloji (Apple, Amazon, AMD, ARM, Broadcom, Facebook, Google, Hulu, Intel, IBM, Microsoft, Netflix, NVIDIA, Realtek, Sigma le ba bang ba bangata), ho bohlokoa ho lebella tšehetso ea lisebelisoa bakeng sa AV1 lilemong tse tlang.
Hajoale, khoutu ea video ea AV1 ha e hloke tefo ea litefiso tsa laesense bakeng sa ts'ebeliso ea litokelo tse itseng tseo e leng tsa litho tsa Alliance for Open Media (AOMedia). Leha ts'ebetso ea ho kenyelletsa tokelo ea molao ho AV1 e hloka maikutlo a litsebi tse peli hore ha e hataketse litokelo tsa mang kapa mang, ho lula ho na le li-patent troll tseo litokelo tsa tsona li lulang li hatakeloa ke bohle.
Kahoo, k'hamphani ea Luxembourg Sisvel e bokelletse letamo la litokelo tsa molao tsa 3000 ho tsoa ho lik'hamphani tse ngata tse hlalosang theknoloji e tšoanang le e sebelisoang ho AV1 le VP9. Ho qala ka Hlakubele selemong sena, Sisvel ba lakatsang ho fana ka tumello ea litokelo tsena bakeng sa € 0,32 bakeng sa sesebelisoa se nang le pontšo (TV, smartphone, PC le tse ling) le € 0,11 bakeng sa sesebelisoa se se nang pontšo (chip, player, motherboard le tse ling). Leha Sisvel a sa rera ho lefisa litefiso tsa laesense bakeng sa litaba, ho bonahala software e nkuoa e ts'oana le hardware, ho bolelang hore baetsi ba software ba tlameha ho lefa k'hamphani.
Le hoja Sisvel a e-s'o qale linyeoe tsa molao le baetsi ba hardware le software ('me e ke ke ea qala ho fihlela theknoloji e sebelisoa haholo), ho hlakile hore merero e joalo e teng. Leha ho le joalo, AOMedia sireletsa bankakarolo ho AV1 ecosystem, leha e sa hlalose hore na joang.
Baetsi ba AV1 ba lebelletse hore e tla fumaneha hohle lipolaneteng tsohle, ka hona, lebella hore e se ke ea tšehetsoa feela ke baetsi ba li-chip ba ka sehloohong, baetsi ba mananeo le bafani ba lits'ebeletso, empa hape le ke baetsi ba elektronike ba ka sehloohong.
Leha ho le joalo, ha se tsohle tse monate hakana bakeng sa AV1. Taba ea pele, kaha libapali tse ngata, lithelevishene le mabokose a li-set-top ha li tšehetse codec ena, phetoho ea indasteri eohle ho eona e tla tsamaea butle. Ntle le moo, ho bohlokoa ho hopola hore nakong ea post-8K, bahlahisi ba ntse ba lokisa AV2 codec. Taba ea bobeli, litlhoko tsa li-patent troll li tla fokotsa ka ho hlaka thahasello ea theknoloji har'a lik'hamphani tse ling.
