The overview of digital video broadcasting (DVB) standards is presented. Particular attention is devoted to standards for terrestrial broadcasting, DVB-T and the newest DVB-T2. The comparison between these standards is derived and the advantages of the DVB-T2 over DVB-T are emphasized.
The simulation model of statistical multiplexer for possible use in video multicoder is considered. The scheduling control is realized by neural network, using modified Kohonen learning law. The modifications are derived in order to avoid the packet loss of the overall input streams even in case of bursty traffic. Scheduling mechanism includes the priority of input streams and the rate control mechanism...
The use of Hopfield-like neural network in solving routing and wavelength assignment (RWA) in all-optical networks is considered. Routing assignment was performed under the constraints of minimal wavelength conversions and minimal congestion. The wavelength assignment assumes four basic methods: first-fit, least-used, most-used, and maximal sum with relative capacity loss algorithm. Different RWA...
The routing in packet switching network is considered as a shortest-path (SP) problem. The new routing algorithm, initially inspired by the Hopfield neural network, is designed to find the optimal link between source and destination node taking into account not only the shortest path but also several in-node constraints, including link bandwidth, incoming flow and flow statistics, addressed to avoiding...
