This paper presents robust adaptive information content system design using contiguous buffering scheme buffers for high data rate real-time applications like e-health, telemedicine and 3-D video using IP network. The design improves the resiliency of the realtime systems under adverse network conditions like congestion and/or temporary loss of connectivity and ensures that critical application data is not lost. The proposed adaptive information content management design for a high data rate real-time application shows how information content can be adaptively managed using contiguous sender buffer to reduce the data transfer rate when underlying network capacity changes over a time period, improving the survivability interval of the system. There is a tradeoff between loss of features, data rate reduction, criticality of the lost information and survivability time of the systems.

The use of reduced-state sequence estimation techniques in a digital subscriber loop receiver is discussed. These techniques offer a potential performance improvement over conventional equalization techniques such as decision feedback equalization (DFE). Stationary and cyclostationary NEXT noise models are described. The theoretical performance obtainable from a Viterbi algorithm receiver with stationary white Gaussian noise, stationary NEXT, and cyclostationary NEXT noise models is estimated, and the reduced-state decision feedback sequence estimation and M algorithms are reviewed. It is shown that the improvement can be especially significant in the presence of cyclostationary crosstalk because of the freedom that sequence estimation receivers afford in the choice of receiver sampling phase. This advantage is evaluated for Viterbi algorithm receivers. By simulation of two practical reduced-state sequence estimation receivers, it is demonstrated that, in the presence of cyclostationary crosstalk, a substantial increase in maximum loop range (or equivalently, maximum bit rate) may be achievable compared to conventional DFE equalization.>
