Abstract

Osnovni cilj Magistarske radnje je prikazati mehanizme koji se koriste u postupku kompresije videosadržaja, usporediti svojstva različitih standarda u njihovim implementacijama koje se temelje na otvorenom kodu te na osnovu ispitivanja dati zaključak u obliku prijedloga za optimalno kodiranje videosadržaja u praksi. Rad nastoji dati zaokruženi uvod u područje kodiranja videosadržaja s naglaskom na MPEG 4 standard odnosno njegov MPEG 4 dio 10 Advanced Video Coding (H.264) implementiran u obliku otvorenog koda. Magistarski rad se sastoji od osam poglavlja, a logički se može podijeliti na tri glavna dijela. U prvom dijelu daje se općenit uvod u kodiranje videosadržaja. Drugi dio objašnjava mehanizme i metode kodiranja koji se koriste u kodiranju kao i načine mjerenja kvalitete videosadržaja. Treći praktični dio prikazuje rezultate usporednog testiranja i analizu utjecaja pojedinih parametara kodera na kvalitetu kodiranog videosadržaja i performanse procesa kodiranja te završava sa zaključkom kako treba u praksi kodirati videosadržaj.

Abstract (english)

The Master's thesis main goal is to show methods used in process of video coding, compare features of different video standards in their implementations based on open source code and, backed by practical codings and quality assessments, give the conclusion in form of suggestion for optimal video coding in praxis. The thesis gives a general introduction into area of video coding with emphasis on MPEG 4 standard, specially its part defining video coding MPEG 4 part 10 Advanced Video Coding (H.264) but implemented in open source. The Master's thesis consist of eight chapters, logically divided into three parts. First part gives a general overview of video coding, second part describes mechanisms used in video coding and video quality assessment methods, and final third part shows practical video coding, comparison testing and how some codec parameters affect the video coding quality and performance. Backed on testing results, the conclusion gives a recommendation for optimal set of parameters for video coding in praxis.
