This paper presents a prioritization scheme based on an analysis of the impact on objective video quality when dropping individual\r\nslices from coded video streams. It is shown that giving higher-priority classified packets preference in accessing the wireless media\r\nresults in considerable quality gain (up to 3 dB in tests) over the case when no prioritization is applied. The proposed scheme is\r\ndemonstrated for an IEEE 802.11e quality-of-service- (QoS-) enabled wireless LAN. Though more complex prioritization systems\r\nare possible, the proposed scheme is crafted for mobile interactive or user-to-user video services and is simply implemented within\r\nthe Main or the Baseline profiles of an H.264 codec.
