| Abstract: | In this paper, we propose an unequal Luby transform (LT) based on block weight shift (ULT-BWS) method as an unequal forward error correction method to minimize video distortion over packet-lossy networks. First, we consider unequal amount of error propagation effects from packet loss in hierarchical prediction structure to give unequal property in an LT codes. For robust video transmission over various channel status, the ULT-BWS method assigns an efficient amount of protection for frame blocks with different error propagation weights by controlling the range of more important blocks in a group of pictures. Simulation results demonstrate that the proposed ULT-BWS method gives robust performance and significantly improved video quality, compared with the conventional ULT schemes. [ABSTRACT FROM AUTHOR] |
