Abstract :
When an access point transmits multi-view video over wireless networks with multiple subcarriers, errors occur in low quality subcarriers. The errors cause a significant degradation of video quality. The present paper proposes Significance based Multi-view Video Streaming with Subcarrier Allocation (SMVS/SA) for the maintenance of high video quality. SMVS/SA transmits a significant video frame with a high quality subcarrier to minimize the effect of the errors. Evaluations using MERL´s benchmark test sequences reveal that SMVS/SA achieves a slight degradation of video quality. For example, SMVS/SA improves video quality by 8.0 [dB] compared to standard H.264/AVC MVC when the maximum packet loss ratio of each subcarrier is 10 %.
