Abstract
Stereoskopski prikaz omogućuje kod ljudi stvaranje osjećaja dubine prilikom gledanja 2D slike. Metode se dijele na aktivne i pasivne, a razlikuju se po načinu prikaza ovisno radi li se o vremenskoj ili prostornoj podijeli slike. Neovisno o kojem se načinu prikaza radi, potrebna je kvalitetna kompresija zbog velike količine podataka i zahtijevane brzine prijenosa. H.264 je vrlo efikasan koder koji također podržava i MVC – specifično kodiranje stereoskopskih sekvenci. U ovom radu je, koristeći FFmpeg program i implementirani x264 koder, izrađena baza sekvenci kodiranih CBR i VBR metodama, koje se suštinski razlikuju. VBR metoda je dala kvalitetnije rezultate – subjektivno, ali i po objektivnim mjerama, no uz nepredvidljive veličine datoteka.

Parallel abstract (English)
Stereoscopic display creates illusion of depth in an image by means of stereopsis. The most dominant methods today for displaying stereoscopic images are active shutter and passive polarizing methods. Simultaneous projection of images is enabled either by temporal or spatial division, respectively. Both of these methods require great compression ratios due to their high bitrates. H.264 is a very efficient video codec that also supports MVC – stereoscopic video specific coding. This project resulted in 3DTV test sequence database encoded using FFmpeg software and x264 codec. Sequences were encoded using CBR as well as VBR encoding. VBR encoding resulted in higher quality video sequences but with unpredictable file sizes.
