Year: 2016 | Conference Paper |

HTML

This paper investigates the capabilities of Hierarchical Quadrature Amplitude Modulation (HQAM) to provide Unequal Error Protection (UEP) to H.264/AVC encoded video bitstream. The UEP is based on the asymmetrical error sensitivity of the coded bitstream and exploits data partitioning mode of H.264/AVC to provide protection to their sensitivity to channel errors. The more important bits called High...Show More

Transmission of coded video over erroneous channels (e.g., Internet and wireless networks) is always a challenging task. Error control strategies, to combat the channel errors, are generally applied at individual network layers leading to inefficient utilization of resources. The cross-layer design has emerged as alternative for efficient utilization of the available resources, such as bandwidth, ...Show More

The wavelet-based video coders are excellent in providing the fine granular scalability (FGS), i.e. progressive bitstream, which can be used to multicast the video transmission to different users requiring different bit-rate, resolution and frame rate, from single coded bitstream. However, transmission of these bitstreams over erroneous channel is a challenging task. In this paper, application lay...Show More
