We present a white space communications test bed running in the Scottish Highlands and Islands, and discuss its feasibility for smart grid communications. The network aims to serve communities that have great potential for distributed generation of electricity, by means of wind, water, and tidal power. However, smart grid applications such as remote meter reading and load balancing are impaired by the scarcety or lack of communications infrastructure in remote rural areas such as the Scottish Highlands and Islands. We argue that the proposed system is based on a network of energy self-sufficient radio relay nodes that make it a robust and independent medium to support smart grid communications in rural settings. © 2011 IEEE.

The MPEG-4 standards define a technique for 3D facial and body model animations (FAPS/BAPS respectively), as seen in animation systems such as Greta. The way this technique works is in contrast to the set of animation techniques currently used within modern games technologies and applications, which utilize more advanced, expressive animation systems such as Skeletal, Morph Target, and Inverse Kinematics. This article describes an object-oriented, Java-based framework for the integration and transformation of MPEG4 standards-compliant animation streams known as Charisma. Charisma is designed for use with modern games animation systems; this article illustrates the application of this framework on top of our Java/OpenGL-based games engine framework known as Homura. © 2010 ACM.

Broadcasters are now transmitting 5.1-channel surround sound as part of their HD TV services. However, since much of the audio content in original programme material is 2-channel stereo, broadcasters are required to switch between the two formats. Switching between 2 and 5.1-channel formats can cause problems in decoding the content, including switching artefacts and loudness changes. In general it is preferable to transmit all programme audio in 5.1 surround, and this can be achieved by automatically up-mixing any 2-channel stereo content to 5.1 format prior to broadcasting. This paper reports on tests designed to assess the subjective performance of a selection of upmixers for use in the broadcast chain.

This paper presents a Case Study of the BBC's recent research and development work into the user experience of Internet-Connected Television. User expectations and aspirations around their TV experiences are changing radically as the platform increasingly supplements broadcast network connectivity with IP connectivity. Despite the relative youth of the platform, it is clear that Connected TV and its users support and seek user experiences which are quite distinctive from web browsing on personal computers, or earlier forms of interactive TV platforms. We describe a number of the BBC's recent research projects developing knowledge and tools to support future user experiences for TV, ranging from typography to alternative input interfaces. In each case, we describe the motivation, the development approach and the empirical assessment of impact of the technology and experiences embodied by our prototypes. © 2012 ACM.
