Abstract

Napredak mrežnih tehnologija i stalno povećanje pristupne brzine do krajnjeg korisnika omogućavaju transfer videosignala i pružanje novih usluga koje uključuju različite multimedijske sadržaje. Ovaj rad objašnjava karakteristike paketskih mreža koje su od značaja za izvedbu transfera videosignala. Opisane su značajke normi za kodiranje videosignala kao što su MPEG-2, H.261, H.263 i H.264 te su vrednovane karakteristike odgovarajućih kodeka. Razmotrena su dva primjera sustava za transfer videosignala: videokonferencijski sustav i distribucijski sustav. Objašnjene su tehnologije za obje vrste prijenosa preko ATM mreža i mreža zasnovanih na IP protokolu. Pored toga navedena su konkretna rješenja za potrebe distribucije videosignala u raznim okruženjima, koja uključuju i interaktivnu televiziju, čija implementacija obuhvaća široki spektar korištenih mrežnih i videotehnologija.

Abstract (english)

Transmission of video signal and providing multimedia services over packet networks were made possible by development of network technologies and constant growth of end user bandwidth. This thesis explains characteristics of packet networks that are important for transmission of video signal. Video standards such as MPEG-2, H.261, H.263 and H.264 are described and main characteristics of video codecs are evaluated. Two examples of video transmission are considered: video conferences and video distribution. Technologies for both modes are explained for transmission over ATM and IP networks. The solutions for video signal distribution are shown in variety of network environments including interactive television that uses wide range of network and video technologies.
