Primerjava standardov video kodiranja H.264 AVC in H.265 HEVC

KARAMEHIĆ, BERIN (avtor), Burnik, Urban (mentor)

Diplomska naloga obravnava tematiko video kodiranja. Opisani so različni video kodirni standardi in postopki zgoščevanja video vsebine. Največ poudarka sem namenil novemu kodirnemu standardu H.265/HEVC ter njegovem predhodniku H.264/AVC. Uvod dela sem začel z osnovnimi tehnikami, ki jih uporabljamo pri zgoščevanju videa, opisal pa sem tudi postopek zgoščevanja statičnih slik. Izpostavil sem najpogostejši standard JPEG. Nadaljeval sem z zgoščevanjem gibljive slike ter opisom standardov MPEG-1, MPEG-2 ter MPEG-4. Sledila je primerjava danes najbolj uporabljenega video kodirnega standarda H.264/AVC z njegovim naslednikom H.265/HEVC. Najprej sem teoretično opisal oba standarda. Tukaj sem naredil poudarek na kodirnih orodjih, ki jih oba standarda vključujeta pri video kodirnem procesu. V zadnjem poglavju sem izvedel še test med H.264/AVC in H.265/HEVC. To sem naredil tako, da sem s pomočjo programov Hybrid in Handbrake, ki vsebujeta x264 ter novi x265 kodek, subjektivno ovrednotil kvaliteto novega HEVC kodirnika.

My thesis deals with the topic of video coding. I describe different video coding standards and processes of video compression, mainly focusing on the new H.265/HEVC coding standard and its predecessor H.264/AVC. In the introduction, I present the basic techniques that are used in video compression and I also describe the process of still image compression, emphasizing on the most common of them – the JPEG standard. I continue with the process of moving image compression and a description of its various standards: MPEG-1, MPEG-2, and MPEG-4. I follow that up with a comparison of the most-used video coding standard today, H.264/AVC, to its successor, H.265/HEVC, first within a theoretical description of the both and then focusing on the coding tools that are used by both standards in the video coding process. In the last chapter, I perform a test between H.264/AVC and H.265/HEVC, using the Hybrid and HandBrake program, both of them containing the x264 codec and the new x265 codec, in order to subjectively evaluate the quality of the new HEVC encoder.
