MPEG-2 video streaming over IEEE 802.11g WLAN in the presence of Bluetooth interference

We investigate the impact of Bluetooth (BT) interference on the performance of MPEG-2 streaming video over the IEEE 802.11g physical layer. Symbol erasures are used to remove the BT interference and restore video quality. A novel perceptual quality metric is used to quantify the optimum number of erasures required to restore video quality as close as possible to its unimpaired level. The results demonstrate that a perceptual video quality metric provides an effective control mechanism as it accounts for both video encoding and transmission impairment attributes.
