Abstract

U stalnom su porastu zahtjevi glede kvalitete usluge video strujanja u pokretnoj mreži, stoga raste i važnost predviđanja video kvalitete. U radu su promatrani elementi (video sadržaj, uslužna infrastruktura, mreža, uređaj, korisnik) koji značajno utječu na QoE, doživljenu iskustvenu kvalitetu video sadržaja. U tu svrhu mjereni su QoS parametri (gubitak paketa, kašnjenje, kolebanje kašnjenja) i parametri objektivne metrike (PSNR, zrnatost, zamućenje). Usporedbom izmjerenih rezultata izvornih, ulaznih i izlaznih video sekvenci pokazane su mogućnosti i ograničenja glede predviđanja subjektivne ocjene video kvalitete. Ispitivanja su provedena na stvarnoj mreži, u stvarnim uvjetima i s komercijalnim pokretnim uređajem.

Abstract (english)

With the increasing demands for video streaming service over mobile network reliable prediction of video quality has increased in importance. In this work are observed elements (video content, infrastructure, network, mobile device) which significantly affect the QoE. For this purpose, QoS parameters (packet loss, delay, jitter) and objective metric (PSNR, blockiness, blurriness) are measured. Comparing the measured results of the original, input and output video sequences, possibilities and limitations regarding subjective assessment prediction of video quality are shown. Tests were conducted in a real network with real conditions and with an actual mobile device.
