In order to accommodate various multimedia services, next generation wireless networks are characterized by very high transmission bit rates. Thus, in such systems and networks, the received signal is not only limited by noise but especially with increasing symbols rate often more significantly by the intersymbol interference (ISI) caused by the time(More)
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)
