Microsoftu odobren patent za GPU-ubrzano video enkodiranje

13.10.2010
Microsoft logoMicrosoft je još 2006-e podneo zahtev za patent pod naslovom “Accelerated video encoding using a graphics processing unit” (Ubrzanje video enkodiranja korišćenjem grafičkog procesora) i sada, šest godina posle, patent im je odobren.

Patent pokriva sve osnovne operacije GPU-ubrzanog video enkodiranja, što daje Microsoftu kontrolu nad ovom već poprilično prihvaćenom tehnologijom.

Početak dostupnosti ove tehnologije je bio 2007-e, sa dolaskom DirectX 10 i Windows Vista. Nvidia podržava ovu tehnologiju od 2008-e preko svojih grafičkih kartica sa CUDA tehnologijom. AMD kod svojih Radeon HD grafičkih kartica takođe nudi GPU-ubrzanje. Prvi enkoder koji je koristio GPU za video enkodiranje je Badabom koji se pojavio krajem 2008-e.

Microsoft takođe ugrađuje ovu tehnologiju u svoje proizvode. Novi popularni operativni sistem, Windows 7, već ima ugrađenu podršku za GPU-ubrzane operacije preko DirectX-a. Nadolazeći web browser internet Explorer 9 takođe koristi GPU-ubrzanje za rendering web stranica i prikaz video sadržaja.
