Abstract

This paper proposes a Flexible Significance Classification (FSC) mechanism for video data over managed IP networks. FSC determines the video packet significance in both temporal and spatial domains. In the temporal domain, FSC evaluates the packet significance based on the estimated error propagation provided a packet is lost. In the spatial domain, FSC computes the packet significance based on the content complexity in a packet. Compared with traditional significance classification scheme, simulation results show that the proposed mechanism can significantly improve the accuracy of signification determination by up to 13% and effectively improve the received video quality by up to 0.54dB in PSNR.
