In video compression, throughputs of entropy encoders based on arithmetic coding are limited. This article presents the architecture of the entropy coder able to process in each clock cycle much more binary symbols than previous works. The architectu

Assume that $K$ is a field and $I_{1}\subsetneq ...\subsetneq I_{t}$ is an ascending chain (of length $t$) of ideals in the polynomial ring $K[x_{1},,...,x_{m}]$, for some $m\geq 1$. Suppose that $I_{j}$ is generated by polynomials of degrees less or

Binary arithmetic coding is a key part of recent video compression standards. Its throughput is limited by the inherent dependencies existing in the algorithm. As a consequence, a higher bin parallelism leads to lower clock frequencies. This paper pr

This article discusses the construction of a prototype of a platform that provides the integration of video signals from multiple sources. Video sources can be both existing CCTV systems based on analog cameras, modern systems based on IP cameras and

Assume that [Formula: see text] is a superoperator which preserves hermiticity. We give an algorithm determining whether [Formula: see text] preserves semipositivity (we call [Formula: see text] positive in this case). Our approach to the problem has

We give an algorithm determining whether a hermiticity-preserving superoperator is positive. In our approach we apply techniques of quantifier elimination theory for real numbers. Furthermore, we argue that quantifier elimination theory should play m

In this article discusses the design for high-resolution video involves some challenges, mainly in encoder architectures. First, provided the same algorithm, the amount of computations increases proportionally to the number of processed pixels or to
