A Quality Ratio-Based Novel Unequal Loss Protection Scheme in Wi-Fi Broadcasting System

Dong Hyun Kim, Jong Min Kong, and Jong Deok Kim
Abstract—The Wi-Fi broadcast system using the broadcast packet transmits the multimedia contents to many local mobile users in real time and it must use the FEC technology to recover the broadcast packet loss, because Media Access Control layer retransmission is not supported for broadcast packet loss. Equally adding the redundant packet is not very efficient due to the nature of the multimedia data. So, several studies have been made on the Unequal Loss Protection (ULP). Proposed ULP system can efficiently add the redundant packet to the source video data with experimentally modeling the deterioration of video according to the broadcast packet loss in Wi-Fi based broadcasting system. In order to predict the video deterioration, we use the Expected Quality Ratio (EQR). It is a ratio of the video deterioration of compression to the video deterioration of packet loss. And, we design the framework of ULP system to predict the video quality using the EQR. We implement and experiment the proposed algorithm. Experiment results show how our algorithm outperforms other recovery methods of packet loss.

Index Terms—Wi-Fi broadcasting system, video deterioration modeling, ULP, FEC.
