Abstract

U radu se daje pregled HDTV formata, te značajke H.264/AVC i HEVC kodera.
Opisane su postavke programskog paketa FFMPEG potrebne za kodiranje izvornih
videosekvenci koristeći željene kodere. U sklopu rada je razvijena programska
potpora za automatiziranje postupka kodiranja videosekvenci i za računanje
objektivnih mjera kvalitete slike kodiranih sekvenci, te obradu rezultata i njihov grafički
prikaz. Objektivne mjere kvalitete korištene u ovom radu su PSNR i SSIM. Pomoću
grafičkog prikaza rezultata napravljena je analiza objektivnih mjera kvalitete za
pojedine HDTV formate i pojedine kodere, na temelju koje je donesena inicijalna
preporuka.

Abstract (english)

This student's work gives overview of HDTV formats and characteristics of
H.264/AVC and HEVC coders. Settings needed for FFMPEG software for encoding
source video sequences using wanted coders are described. As part of this student's
work, software was develop for automatization of encoding procedure for video
sequences and for calculating objective picture quality measures of encoded
sequences, as well as for result processing and graphic display of results. Objective
quality meusres used in this student's work are PSNR and SSIM. Using graphic
results, analysis of objective quality mesures was made for each HDTV format and
each coder and on base of analysis, initial recommendation was made.
