Abstract
U ovom radu dan je kratak opis osnovnih vrsta video usluga te njihovih zahtjeva i ograničenja. Objašnjen je i TCP/IP model kroz slojeve te najznačajniji protokoli za prijenos videa pojedinih slojeva. Opisani su procesi kodiranja videa te dvije novije norme kodiranja H.264/MPEG-4 AVC i SVC. Napravljena je analiza promjene parametara kodiranja, parametara mreže i sadržaja video sekvenci te njihov utjecaj na kvalitetu videa prenesenog kroz mrežu. Video sekvence kodirane su korištenjem vremenske skalabilnosti te kombinirane vremenske skalabilnosti i MGS skalabilnosti kvalitete. Kodirane sekvence prenesene su kroz 802.11e bežičnu mrežu dodjeljujući različite prioritete različitim slojevima videa. Na primljene sekvence primijenjene su objektivne metrike PLR i MS-SSIM za ocjenu kvalitete. Kodiranje kombiniranom skalabilnosti daje dobre rezultate i pri lošijim uvjetima prijenosa. Pokazalo se da osim mrežnih uvjeta te načina kodiranja i sadržaj video sekvenci ima značajan utjecaj na kvalitetu video prijenosa.

Parallel abstract (English)
In this paper, a brief description of the main applications that uses video transmission over IP is given. Also, the TCP/IP model through its layers and the most important protocols for video transmission are explained. The processes of video encoding and two recent coding standards H.264/MPEG-4 AVC and SVC are described. The impact of the encoding parameters, network parameters and video content on the overall video quality is analyzed. Video sequences are coded using temporal scalability and combined temporal and MGS scalability. Coded sequences are transferred through 802.11e wireless network assigning different priorities to the video layers. PLR and MS-SSIM objective metrics were used to evaluate a quality of received sequences. It turned out that combined scalability gives good results at poor transmission conditions. The obtained simulation results state that in addition to network conditions and coding methods, video content has a significant impact on the quality of transmitted video.
