Codecul prezentat \u00een 2018 AV1<\/a><\/noindex> a fost sus\u021binut de juc\u0103torii principali de pe pia\u021ba streaming-ului. Furnizorii de hardware au confirmat suportul pentru noul codec, iar dispozitivele finale cu decodare hardware AV1 ar trebui s\u0103 apar\u0103 p\u00e2n\u0103 la sf\u00e2r\u0219itul anului. \u00cen acest context, trollii patentelor au devenit activi cu cerin\u021be financiare.<\/p>\n

\"Dispozitivele<\/p>\n

Codec video AV1<\/a><\/noindex> cu surs\u0103 deschis\u0103 a fost dezvoltat de inginerii de la mai multe companii, inclusiv Amazon, BBC, Netflix, Hulu \u0219i altele, care au creat Alliance for Open Media (AOMedia). Noua tehnologie este destinat\u0103 \u00een principal pentru streaming video la rezolu\u021bii ultra-\u00eenalte (4K \u0219i mai mari), cu o palet\u0103 de culori extins\u0103 \u0219i diverse tehnologii HDR. Printre principalele caracteristici ale codec-ului AOMedia se num\u0103r\u0103 o eficien\u021b\u0103 cu 30% mai mare<\/a><\/noindex> a algoritmului de compresie comparativ cu metodele existente, cerin\u021be predictibile pentru capacit\u0103\u021bile de calcul ale hardware-ului, precum \u0219i flexibilitate \u0219i scalabilitate maxim\u0103.<\/p>\n

\"Dispozitivele<\/p>\n

Companiile men\u021bionate cu propriile servicii de streaming au nevoie de codec-uri eficiente ca de aer. \u00cen primul r\u00e2nd, AV1 permite reducerea cerin\u021belor de l\u0103\u021bime de band\u0103 a conexiunii la Internet at\u00e2t la nivelul centrele de date (CDP), c\u00e2t \u0219i la nivelul furnizorilor \u0219i utilizatorilor finali. \u00cen al doilea r\u00e2nd, utilizarea filmului de 65 mm Amazon Studios \u0219i a camerelor IMAX MSM 9802 (care sunt foarte greu de \u00eenchiriat) \u0219i RED Monstro pentru filmul Aeronauts (The Aeronauts<\/a><\/noindex>) arat\u0103 c\u0103 compania se preg\u0103te\u0219te pentru era post-4K, c\u00e2nd codec-urile actuale nu vor p\u0103rea la fel de eficiente.<\/p>\n

\"Dispozitivele<\/p>\n

C\u00e2t despre decodoarele software, \u00een prezent acestea sunt suportate<\/a><\/noindex> sunt sus\u021binute de un num\u0103r mare de companii, inclusiv Cisco, Google, Netflix, Microsoft \u0219i Mozilla. Totu\u0219i, decodarea software \u00eenseamn\u0103, de obicei, un consum de energie crescut \u0219i o utilizare foarte limitat\u0103. De aceea, este interesant s\u0103 vedem suportul pentru decodarea hardware.<\/p>\n

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

Compania Chips & Media a fost una dintre primele care a prezentat un decodor hardware AV1 \u00een octombrie anul trecut. Procesorul video Wave510A<\/a><\/noindex> reprezint\u0103 o proprietate intelectual\u0103 licen\u021biat\u0103 (sintetizabil\u0103 la nivel RTL), care poate fi integrat\u0103 \u00eentr-un sistem-pe-chip (system-on-chip, SoC), utiliz\u00e2nd magistrale interne ARM AMBA 3 APB \u0219i ARM AMBA3 AXI. Acest decodor suport\u0103 codec-ul AV1 de nivel 5.1, cu un bitrate maxim de 50 Mbps, o ad\u00e2ncime de culoare de 8 sau 10 bi\u021bi, precum \u0219i subdizabilizarea culorii 4:2:0. Configura\u021bia monocore Wave 510A la o frecven\u021b\u0103 de 450 MHz poate fi utilizat\u0103 pentru decodificarea fluxurilor \u00een rezolu\u021bie 4K la o rat\u0103 de cadre de 60 Hz (4Kp60), \u00een timp ce configura\u021bia bicore poate fi folosit\u0103 pentru decodificarea fluxurilor 4Kp120 sau 8Kp60.<\/p>\n

\"Dispozitivele<\/p>\n

Pe l\u00e2ng\u0103 Chips & Media, procesoarele video licen\u021biate cu suport pentru AV1 sunt oferite \u0219i de alte companii. De exemplu, Allegro AL-D210 (decodor) \u0219i Allegro E210 (encodor)<\/a><\/noindex> suport\u0103 at\u00e2t AV1, c\u00e2t \u0219i alte formate populare, inclusiv H.264, H.265 (HEVC), VP9 \u0219i JPEG. \u00cen plus, acestea suport\u0103 subdizabilizarea culorii 4:2:0 \u0219i 4:2:2 pentru aplica\u021bii de consum \u0219i profesionale. De asemenea, Allegro a men\u021bionat c\u0103 aceste solu\u021bii au fost licen\u021biate de furnizorii de echipamente de prim\u0103 linie \u0219i vor fi utilizate \u00een dispozitivele finale care vor fi lansate p\u00e2n\u0103 la sf\u00e2r\u0219itul anului.<\/p>\n

\"Dispozitivele<\/p>\n

Pe l\u00e2ng\u0103 procesoarele video licen\u021biate, mai mul\u021bi dezvoltatori au anun\u021bat sisteme integrate de tip SoC cu suport pentru AV1 pentru televizoare, set-top box-uri, playere \u0219i alte dispozitive similare. Printre aceste solu\u021bii se remarc\u0103 Amlogic S905X4, S908X, S805X2<\/a><\/noindex> cu suport pentru rezolu\u021bii de p\u00e2n\u0103 la 8Kp60, Broadcom BCM7218X<\/a><\/noindex> cu suport pentru 4Kp60, Realtek RTD1311<\/a><\/noindex> (4Kp60) \u0219i RTD2893<\/a><\/noindex> (8Kp60). \u00cen plus, SoC LG \u03b19 de genera\u021bia a treia, care sunt utilizate \u00een televizoarele 8K ale companiei din 2020, suport\u0103 de asemenea AV1. De asemenea, MediaTek a anun\u021bat sistemul s\u0103u mobil de tip SoC Dimensity 1000 cu decodor AV1 hardware.<\/p>\n

A\u0219a cum se poate observa, suportul pentru decodificarea hardware a fluxurilor AV1 din partea dezvoltatorilor de procesoare video licen\u021biate \u0219i cipuri este \u00eenc\u0103 destul de modest. Totu\u0219i, av\u00e2nd \u00een vedere suportul pentru noul codec din partea unui num\u0103r mare de companii tehnologice (Apple, Amazon, AMD, ARM, Broadcom, Facebook, Google, Hulu, Intel, IBM, Microsoft, Netflix, NVIDIA, Realtek, Sigma \u0219i multe altele), se poate a\u0219tepta suport hardware pentru AV1 \u00een anii urm\u0103tori.<\/p>\n

Formal, the AV1 video codec does not require royalty payments for the use of certain patents owned by members of the Alliance for Open Media (AOMedia). Although the process of including any given patent in AV1 requires the agreement of two experts that it does not infringe on anyone's rights, patent trolls always seem to find rights that are allegedly violated by everyone.<\/p>\n

\"Dispozitivele<\/p>\n

Thus, the Luxembourg-based company Sisvel has gathered a pool of 3000 patents from dozens of companies that describe technologies similar to those used in AV1 and VP9. Starting in March of this year, Sisvel ofer\u0103<\/a><\/noindex> is offering to license these patents for \u20ac0.32 for a display device (television, smartphone, PC, and others) and \u20ac0.11 for a device without a display (chip, player, motherboard, and more). Although Sisvel does not plan to charge royalties for content, it seems that software is treated the same as hardware, meaning that software developers must pay this company.<\/p>\n

\"Dispozitivele<\/p>\n

Although Sisvel has not yet begun legal disputes with hardware and software creators (and will not start until the technology becomes widely adopted), it is quite evident that such intentions exist. However, AOMedia planific\u0103<\/a><\/noindex> aims to protect the participants in the AV1 ecosystem, although it does not explain how exactly.<\/p>\n

The creators of AV1 are counting on its widespread adoption across all platforms, so it should be expected that it will be supported not only by large chip developers, software creators, and service providers, but also by leading consumer electronics manufacturers.<\/p>\n

\"Dispozitivele<\/p>\n

Nevertheless, not everything is so bright for AV1. Firstly, since most players, televisions, and set-top boxes do not support this codec, the industry's transition to it will be relatively slow. Additionally, it should be noted that developers are preparing codec AV2 for the post-8K era. Secondly, the demands of patent trolls will clearly reduce interest in the technology among some companies.<\/p>\n
