Analysis of Characteristics of Video Quality for Unequal Loss Protection in Wi-Fi Based Broadcasting System

The Wi-Fi based broadcasting system using broadcast packets not the unicast packets of WLAN aims to provide the same quality of multimedia streaming to increased numbers of users. However, for the broadcasting packet without MAC level retransmission, packet loss is unavoidable and the place where the loss of broadcast packet occurs is not predictable. Therefore, the quality of received video is variable depending on the loss. To improve the quality of received video under this circumstance, this study is applying the unequal loss protection method based on predicted quality according to the loss of frame. To achieve this, we are going to analyze the characteristics of quality of received video while considering the unequal loss protection.
