The paper compares the Objective Quality of Standard test image akio.yuv for DCT Coefficients to Integer Transform Coefficients Conversion & vice versa for the purpose of MPEG-2 to H.264 & vice Versa transcoding. The conversions are compared on the basis of PSNR (Peak Signal to Noise Ratio) between original & reconstructed image(More)
In view of increasing use of video transmission over wireless channels, a lot of research efforts have been made to trade-off the error resiliency and transmission bandwidth requirements. This in turn has led to development of various unequal error protection (UEP) schemes. In this paper, the performance of optimized 2-layered and 3-layered UEP schemes(More)
