Abstract
Razvoj sustava pokretnih komunikacija se ubrzano kreće prema trećoj generaciji, tj. prema UMTS sustavima. Brzina prijenosa informacija je već u sustavima druge generacije povećana, a bitno povećanje se očekuje nakon implementacije UMTS sustava. Istodobno, u razvoju usluga se pojavljuju multimedijske usluge, kao npr. prijenos slika i video odsječaka u raznim aplikacijama. Obrada i prijenos slika je definirana standardima JPEG (za prijenos mirne kromatske slike), JPEG 2000 (nadopuna JPEG standarda) i MPEG (za prijenos video signala). Pri prijenosu slike koriste se tehnike kompresije i kodiranja podataka, kako bi se tok informacija što više prilagodio karakteristikama prijenosnog puta u sustavima pokretnih komunikacija. Koriste se diskretna kosinusna transformacija i diskretna wavelet transformacija, dvije tehnike obrade signala koje se oslanjaju na uklanjanje statističke i subjektivne redundancije iz sadržaja slike. Kvaliteta koja se postiže tim postupcima je uvijek kompromis između parametara koji su određeni samom tehnikom kompresije i zahtjeva korisnika.
Abstract (english)
Mobile communications development is moving toward third generation systems (UMTS). In second-generation systems sending information became faster but real improvement is expected in UMTS. In the same time, in services development first multimedia services are becoming operational, like sending still or moving pictures. Analysis and transport of the picture is define in the standards JPEG (for still images), JPEG 2000 (extension of JPEG) and in MPEG standard (for moving pictures). In picture transport, compression techniques are used, as well as coding techniques, in order to adjust picture characteristics to the transport path characteristics in the mobile communications. Discrete cosine transformation and discrete wavelet transformation are used, and both techniques are based on removal of statistic and subjective redundancies. Quality obtained by the mentioned techniques is compromise between parameters defined by the used technique and user demands.
