چکیده
We compare the performance of video compression algorithms in terms of compression ratio, video distortion and computation time in order to study the feasibility of a real time software videophone for 64 kbits/s channels, with exible user deened compression methods. We can combine and adjust the compression algorithms to the required bandwidth and video quality. We introduce the double logarithmic CORT Diagram , which is a novel, visual method to combine and evaluate video compression algorithms. The implemented algorithms are subsampling, block truncation coding (BTC), adaptive discrete cosine transform (ADTC) and conditional refreshment.

A guaranteed minimum throughput service for TCP flows using measurement-based admission control
We propose a new scheme for a network service that guarantees a minimum throughput to flows accepted by admission control (AC). The whole scheme only uses a small set of packet classes in a core-stateless network. At the ingress of the network each flow packet is marked into one of the sets of classes, and within the network, each class is assigned a different discarding priority. The AC method...

متن کاملEfficient Multi-Carrier Communication on the Digital Subscriber Loop
This thesis explores three distinct philosophies for improving the efficiency of multi-carrier communication on the digital subscriber loop. The first topic discussed is impulse response shortening for discrete multitone transceivers. The minimum mean-squared error impulse response shortener is reformulated to allow near-optimal rate performance. It is demonstrated that the best existing eigen-...
