PCs. The reported quality degradation due to the optimization of the encoding algorithm is below 0.6 dB for the tested sequences.
The procedure of averaging generally applied for noise reduction of evoked potentials can probably be improved by weighting the sweeps in dependence on their noise energy, which fluctuates considerably. This article demonstrates that weighting factors must be free of the signal part in the sweeps if underestimation and distortion of the reconstructed evoked… (More)
INTRODUCTION With the growth of the fixed, wireless and mobile Internet, the convergence process of information technology, communication and media faces new challenges. The ISIS project was created to tackle some of these challenges. In particular, it proposes to solve one key issue: procure a technology to provide scalable, seamless multimedia services.… (More)
