Nowadays, wireless communications are becoming the center of attention. Among the different applications, much advancement has been made in video streaming over this type of networks. Wireless networks are error-prone networks. Therefore, as a result of the occurrence of an error, video streams can be incorrectly received and, thus, lost by being discarded by the lower layer entities. Consequently, the decoded video sequence becomes damaged and visual artifacts appear. The scope of this project consists in the implementation and testing of a method in order to increase the quality of H.264/AVC Baseline profile encoded video sequences with QCIF (144x176 pixels) resolution transmitted over error-prone IP-based channels, concretely UMTS networks. In order to increase the quality of this type of video sequences, the followed strategy lies in the protection of those packets which are estimated to cause higher distortion if they are lost.
