We analyze behavior on a TV game show where players’ earnings depend upon several factors. Attractive players fare better than less attractive ones, even though they perform no differently on every dimension. They also exhibit and engender the same degree of cooperativeness. Nevertheless, they are substantially less likely to be eliminated by their peers, even when this is costly. Our results s...

We describe an efficient variation on the z-buffer algorithm for hidden-surface removal in computer-generated images, which allows to selectively post-filter such images in order to reduce the artifacts due to sub-sampling. With a moderate increase in both the computational cost and the memory needs of the classic z-buffer, we filter only those areas where aliasing is most noticeable and improv...

In this paper we describe in detail the recent publications related to video-genre-classification and present our improved approaches for classifying video sequences in real-time as ‘cartoon’, ‘commercial’, ‘music’, ‘news’ or ‘sport’ by analyzing the content with high-level audio-visual descriptors and classification methods. Such applications have also been discussed in the context of MPEG-7 [...

Digital Rights Management (DRM) refers to a broad category of access control technologies aimed at restricting the use and copy of digital content on a wide range of devices. We examine some recent and existing technologies that represent the standards of commercial DRM in most of mainstream media formats including film, e-book, broadcast TV, computer games and music. We discuss the architectur...

Motivation: Multicast applications such as live stream of a football match, IP-based radio stations, webcast of live sessions are ever increasing. In recent years there has been significant commercial interest in using multicast traffic from public-service broadcasters and other DSL TV providers and are expected to grow. This puts pressure on the last-mile wireless technologies such as wireless...
