Abstract
U današnjem svijetu velik dio internetskog prometa odlazi na prijenos video signala. Da bi se krajnjem korisniku mogla pružiti što bolja usluga, tijekom godina su razvijena razna rješenja. Jedno od popularnijih rješenja pod nazivom MPEG-DASH korišteno je u okviru ovog rada. MPEG-DASH se temelji na HTTP protokolu aplikacijskog sloja TCP/IP mrežnog modela i omogućava adaptivan prijenos video signala promjenom kvalitete video sadržaja ovisno o parametrima mreže. Kod MPEGDASH standarda video sadržaj je podijeljen na segmente jednakog trajanja koji su kodirani u više razina kvalitete i postavljeni na poslužitelju. Za odabir segmenata odgovarajuće razine kvalitete koriste se adaptacijski algoritmi smješteni na klijentskoj strani. Iako svi segmenti imaju jednako vremensko trajanje njihova veličina se razlikuje ovisno o sadržaju kojeg prenose. Radi bolje procjene vremena potrebnog za preuzimanje segmenta predlaže se korištenje podatka o veličini pojedinačnog segmenta pri odabiru. U ovom radu analizirana su i implementirana tri odabrana adaptacijska algoritma koji u obzir uzimaju veličinu segmenta. Nakon implementacije izvršena su mjerenja nad različitim video sekvencama, a rezultati su uspoređeni s osnovnim adaptacijskim algoritmom.
Abstract (english)
Nowadays video streaming services make up majority of global Internet traffic. In order to provide best possible quality of service for users, various solutions were developed. One of the most widespread standards, named MPEG-DASH, is used in this paper. MPEG-DASH is based on application layer HTTP protocol of TCP/IP network model and enables adaptive video streaming considering current network parameters. Video content is divided into smaller segments of same duration encoded in different bit rates and stored on server. During media download client side software chooses segments of appropriate bit rate by using adaptation algorithms. Although each segment has the same duration, their sizes vary depending on content. To provide better estimation of time required to download next segment, it was suggested to utilize information about size of each segment. In this paper three segment aware adaptation algorithms were analyzed and implemented. Afterwards their performance was tested and results were compared with results achieved by basic adaptation algorithm.
