2018. aastal esitatud koodeki AV1<\/a><\/noindex> tugesid peamised voogedastusturul tegutsevad ettev\u00f5tted. Riistvaratootjad on kinnitanud toetust uuele koodekile, ning seadmed, millel on AV1 riistvaraline dekodeerimine, peaksid olema turul hiljemalt aasta l\u00f5puks. Sel taustal on patenditrollid aktiivsed, esitades rahalisi n\u00f5udeid.<\/p>\n

\"Seadmed,<\/p>\n

Videokodek AV1<\/a><\/noindex> avalikest allikatest t\u00f6\u00f6tati v\u00e4lja 2015. aastal mitme ettev\u00f5tte inseneride poolt, sealhulgas Amazon, BBC, Netflix, Hulu ja teised, kes l\u00f5id Alliance for Open Media (AOMedia). Uus tehnoloogia on m\u00f5eldud peamiselt voogedastamiseks k\u00f5rgresolutsiooniliste videote (4K ja rohkem) jaoks, sisaldades laiendatud v\u00e4rvipaletti ja erinevaid HDR-tehnoloogiaid. AOMedia toob esile koodeki peamised omadused, sealhulgas 30% t\u00f5husamat<\/a><\/noindex> kompressioonialgoritmi v\u00f5rreldes olemasolevate meetoditega, et prognoosida riistvaralise v\u00f5imekuse n\u00f5udeid ning maksimaalne paindlikkus ja skaleeritavus.<\/p>\n

\"Seadmed,<\/p>\n

Tugavate ettev\u00f5tete jaoks, kellel on enda voogedastusteenused, on t\u00f5husad koodekid h\u00e4davajalikud. Esiteks v\u00f5imaldab AV1 v\u00e4hendada interneti\u00fchenduse l\u00e4bilaskev\u00f5ime n\u00f5udmisi nii andmekeskustes kui ka teenusepakkujate ja l\u00f5ppkasutajate tasandil. Teiseks, Amazon Studios'i 65 mm film ja IMAX MSM 9802 kaamerad (mida on keeruline rentida) ning RED Monstro filmis \"The Aeronauts<\/a><\/noindex>\" n\u00e4itavad, et ettev\u00f5te valmistub post-4K ajaj\u00e4rguks, kui praegused koodekid ei tundu enam nii efektiivsed.<\/p>\n

\"Seadmed,<\/p>\n

Mis puutub tarkvaradekooderitesse, siis praegu ainult ajaliselt piiratud \u00fchekordseid paroole (<\/a><\/noindex> toetab neid mitmed ettev\u00f5tted, sealhulgas Cisco, Google, Netflix, Microsoft ja Mozilla. Samas t\u00e4hendab tarkvaradekodeerimine reeglina alati suurenenud energia tarbimist ja \u00fcsna piiratud kasutust. Seet\u00f5ttu on huvitav j\u00e4lgida riistvaradekooderimise toetust.<\/p>\n

<\/center><\/p>\n

Ettev\u00f5te Chips & Media oli \u00fcks esimesi, kes esitles AV1 riistvaralist dekooderit eelmise aasta oktoobris. Videos\u00fcsteem Wave510A<\/a><\/noindex> on litsentseeritav intellektuaalomand (RTL-tasandil s\u00fcnteesitav), mille saab integreerida s\u00fcsteemidesse-kriips (system-on-chip, SoC), kasutades ARM AMBA 3 APB ja ARM AMBA3 AXI sisemisi bussisid. Antud dekooder toetab AV1 koodeki 5.1 taset, maksimaalset bitikiirus 50 Mbit\/s, v\u00e4rv s\u00fcgavust 8 v\u00f5i 10 bitti, samuti v\u00e4rvi alamsubdiskrimineerimist 4:2:0. \u00dche tuuma konfiguratsioon Wave 510A sagedusel 450 MHz saab kasutada 4K voogude dekodeerimiseks 60 Hz kaadrisagedusega (4Kp60), samas kui kahetuumaline konfiguratsioon v\u00f5ib dekodeerida vooge 4Kp120 v\u00f5i 8Kp60.<\/p>\n

\"Seadmed,<\/p>\n

Lisaks Chips & Media'le pakuvad litsentseeritavad videoprotsessorid toetust AV1-le ka teised ettev\u00f5tted. N\u00e4iteks Allegro AL-D210 (dekooder) ja Allegro E210 (enkooder)<\/a><\/noindex> toetavad nii AV1 kui ka muid populaarseid formaate, sealhulgas H.264, H.265 (HEVC), VP9 ja JPEG. Samuti toetavad nad v\u00e4rvi alamsubdiskrimineerimist 4:2:0 ja 4:2:2 tarbija- ja professionaalses kasutuses. Allegro v\u00e4idab, et need lahendused on litsentseeritud esmaklassiliste riistvaratootjate poolt ja neid kasutatakse l\u00f5ppseadmetes, mis saavad olema turul hiljemalt aasta l\u00f5puks.<\/p>\n

\"Seadmed,<\/p>\n

Lisaks litsentseeritud videoprotsessoritele on mitmed arendajad kuulutanud v\u00e4lja valmis s\u00fcsteemid-kristallidega, mis toetavad AV1 televiisorites, seadmetes, m\u00e4ngijates ja muudes sarnastes seadmetes. Eriti eristuvad Amlogic S905X4, S908X, S805X2<\/a><\/noindex> toetades kuni 8Kp60 resolutsioone, Broadcom BCM7218X<\/a><\/noindex> toetades 4Kp60, Realtek RTD1311<\/a><\/noindex> (4Kp60) ja RTD2893<\/a><\/noindex> (8Kp60). Lisaks toetavad SoC LG \u03b19 kolmanda p\u00f5lvkonna, mis on kasutusel 2020. aasta 8K televiisorites, samuti AV1. Lisaks on MediaTek kuulutanud v\u00e4lja mobiilse s\u00fcsteemi-kristalli Dimensity 1000, millel on AV1 riistvaradekooder.<\/p>\n

Kuid nagu n\u00e4ha, on AV1 voogude riistvaradekoodimise tugi litsentseeritud videoprotsessorite ja mikrokiipide arendajate seas praegu \u00fcsna tagasihoidlik. Siiski, arvestades uue koodeki toetust paljude tehnoloogiaettev\u00f5tete (Apple, Amazon, AMD, ARM, Broadcom, Facebook, Google, Hulu, Intel, IBM, Microsoft, Netflix, NVIDIA, Realtek, Sigma ja paljude teiste) poolt, tasub oodata AV1 riistvaralist toetust tulevikus.<\/p>\n

Formaalsetelt ei n\u00f5ua videokoodek AV1 litsentsitasude maksmist AOMedia liikumise liikmete omamis\u00f5igustega seotud patentide kasutamise eest. Kuigi AV1-sse kuuluva patendi kaasamine n\u00f5uab kahest ekspertist kinnitust, et see ei riku kellegi \u00f5igusi, leidub alati patenditrolle, kelle \u00f5igusi rikutakse igasuguste ja k\u00f5igiga.<\/p>\n

\"Seadmed,<\/p>\n

Nii, Luksemburi ettev\u00f5te Sisvel on kogunud 3000 patenti k\u00fcmnetelt ettev\u00f5tetelt, mis kirjeldavad tehnoloogiaid, mis on sarnased AV1 ja VP9 kasutatavatele. Alates selle aasta m\u00e4rtsist pakub Sisvel pakub<\/a><\/noindex> soovijatele nende patentide litsentsimist hinnaga \u20ac0,32 seadmele, millel on ekraan (telereklaam, nutitelefon, arvuti jne) ja \u20ac0,11 seadmele, millel ei ole ekraani (kiip, m\u00e4ngija, emaplaat jne). Kuigi Sisvel ei plaani litsentsitasusid sisu pealt k\u00fcsida, n\u00e4ib, et tarkvara on v\u00f5rdsustatud riistvaraga, seega peavad tarkvaraarendajad selle ettev\u00f5ttega tasuma.<\/p>\n

\"Seadmed,<\/p>\n

Kuigi Sisvel ei ole seni algatanud kohtuvaidlusi riistvara ja tarkvara tootjate vastu (ega kavatse enne, kui tehnoloogia saab laialdaselt kasutusele), on ilmselge, et sellised kavatsused on olemas. Siiski kavatseb AOMedia Google. See ehitatakse<\/a><\/noindex> kaitsta AV1 \u00f6kos\u00fcsteemi osalisi, kuigi ei selgita, kuidas t\u00e4pselt.<\/p>\n

AV1 looja loodavad selle laialdasele levikule k\u00f5ikidel platvormidel, mist\u00f5ttu on oodata, et seda toetavad mitte ainult suured kiibitootjad, tarkvaraloojad ja teenusepakkujad, vaid ka juhtivad koduelektroonika tootjad.<\/p>\n

\"Seadmed,<\/p>\n

Siiski ei ole k\u00f5ik AV1 jaoks nii roosiline. Esiteks, kuna enamik m\u00e4ngijaid, televiisoreid ja konsoole ei toeta seda koodekit, siis \u00fcleminek kogu t\u00f6\u00f6stuses sellele j\u00e4\u00e4b suhteliselt aeglaseks. Lisaks tuleks meeles pidada, et 8K-j\u00e4rgses ajastus valmistavad arendajad ette AV2 koodeki. Teiseks, patentide r\u00f6\u00f6vlite n\u00f5udmised v\u00e4hendavad selgelt teatud ettev\u00f5tete huvi selle tehnoloogia vastu.<\/p>\n
