| Research Abstract |
In this research, we have proposed a distributed video coding method suitable for resource-constrained devices, such as wireless mobile terminals. The accuracy of the side information is improved by edge information of each frames, which improves the PSNR by 1 to 2dB. Also, a novel joint-source-cryptographic-channel coding has been proposed, where the compression ratio is slightly improved and the decoded error rate is decreased by a factor of two. As an error control coding for storage systems, multilevel coding methods have been proposed for flash memories.
