Abstract	U ovome radu objašnjeni su i analizirani postupci kodiranja multimedijskih podataka za prijenos radiokomunikacijskim mrežama. Opisan je SPIHT algoritam za progresivnu kompresiju slikovnih podataka koji u ispitivanjima služi za kodiranje izvornih podataka. Izveden je dokaz optimalnosti izabranog redoslijeda kodiranja SPIHT algoritmom po skupovima. Definirani su modeli komunikacijskog kanala i dan je pregled postupaka za kanalno kodiranje. Ispitivanjima su uspoređeni postupci odvojenog i združenog kanalnog i izvornog kodiranja za definirane kanale. Na temelju provedene teorijske analize i eksperimentalnih opažanja određen je novi postupak za združeno kanalno i izvorno kodiranje slikovnih podataka koji omogućava nejednoliku zaštitu kodiranih izvornih podataka. Predloženi postupak temelji se na algoritmu za optimalnu raspodjelu zaštite uz korištenje R-D karakteristike komprimirane slike. Postupak je primijenjen na ispitivane kanale, te eksperimentalni rezultati pokazuju da su dobici kodiranja nove metode veći od dobitaka koji se postižu primjenom dosadašnjih postupaka koji koriste jednoliku zaštitu.
Abstract (english)	In this thesis methods for coding of multimedia data with application in wireless network transmission are presented and analysed. As a source coder, SPIHT algorithm for progressive image compression is presented. The optimality of the chosen group coding order using SPIHT is proven. The communication channel models are defined and an overview of channel coding methods is given. Simulations are performed in order to compare different joint and separated methods of channel and source coding for selected channels. Based on theoretical considerations and empirical observations a new method for joint channel and source coding is established, which enables the application of unequal error protection for source data. The new method is based on an algorithm for optimal protection distribution using R-D curve of the compressed image. The new technique is tested in channel simulations. Experimental results show that by using the proposed method coding gains superior to those obtained with preceding methods can be achieved.
