说明

Dynamic Bit-Rate Allocation with Fuzzy Measures for MPEG Transcoding reduction fuzziness, each DCT block is filtered by the least-distortion reduction method to adjust the bit-rate for a target bandwidth. In the experiment, we show the results that the transcoded video quality by the method is better and the bandwidth is more regular than those of existing methods in both visually and quantitatively.

Distributed Multi-source Video Composition on High Capacity Networkswith, however, a strong dependence on the quality of the underlying networking hardware (Gigabit switches), specifically the capability of handling jumbo frames. The experiments have also validated our distributed architecture for composing complex scenes from distributed video sensors.

Design of a Hybrid CDNs, our design attempts to discourage freeloaders and reduces performance problems due to firewalls by incorporating a proxy based structure. This proxy based structure also makes it possible to incorporate caching, which has often been identified as lacking in P2P networks.

Adaptive VoIP Transmission over Heterogeneous Wired/Wireless Networksh coding standards illustrates the performance of the proposed framework. We perform extensive simulations to compare the performance between our adaptive audio rate control and TFRC mechanism. The results show that the proposed mechanism achieves better voice transmission performance, especially when the number of stations is fairly large.

On Modeling MPEG Video at the Frame Level Using Self-Similar ProcessesPEG frame-level processes, depending on the performance metric to study (loss rate, mean delay and jitter). Besides, we claim for the use of self-similar processes, and more concretely, Gaussian F-ARIMA(1,.,0) processes, to adequately capture the correlation structures involved in MPEG video.
