    Dynamic capability and superior firm performance in the UK Media Industry

    The past decade has seen a transformation in the way television broadcasters have managed their businesses. This paper examines the ‘dynamic capability’ of two UK television broadcasters, BskyB and ITV, and their ability to adapt and transform themselves into multi-product, multi-platform media companies. Using Comparative Financial Analysis and Content Analysis of company Annual Reports, it compares and contrasts operating ratios in a time series, to gauge each company’s historical performance over time, whilst also providing inter-company comparisons. It also illustrates how the strategic management of media firms can be significantly different for two companies operating in the same sector. This research demonstrates an original contribution to knowledge in two areas. Firstly, it provides evidence of the dynamic capability performance effects of significant players in UK television broadcasting. Secondly, it extends the limited debate in literature on how to measure dynamic capability performanc

    This article has been made available through the Brunel Open Access Publishing Fund - Copyright @ 2011 Hindawi Publishing CorporationThis paper provides an innovative solution, namely, the distributed storage manager that opens a new path for highly interactive and personalized services. The distributed storage manager provides an enhancement to the MHP storage management functionality acting as a value added middleware distributed across the network. The distributed storage manager system provides multiple protocol support for initializing and downloading both streamed and file-based content and provides optimum control mechanisms to organize the storing and retrieval of content that are remained accessible to other multiple heterogeneous devices

    Semi-automated creation of converged iTV services: From macromedia director simulations to services ready for broadcast

    While sound and video may capture viewers’ attention, interaction can captivate them. This has not been available prior to the advent of Digital Television. In fact, what lies at the heart of the Digital Television revolution is this new type of interactive content, offered in the form of interactive Television (iTV) services. On top of that, the new world of converged networks has created a demand for a new type of converged services on a range of mobile terminals (Tablet PCs, PDAs and mobile phones). This paper aims at presenting a new approach to service creation that allows for the semi-automatic translation of simulations and rapid prototypes created in the accessible desktop multimedia authoring package Macromedia Director into services ready for broadcast. This is achieved by a series of tools that de-skill and speed-up the process of creating digital TV user interfaces (UI) and applications for mobile terminals. The benefits of rapid prototyping are essential for the production of these new types of services, and are therefore discussed in the first section of this paper. In the following sections, an overview of the operation of content, service, creation and management sub-systems is presented, which illustrates why these tools compose an important and integral part of a system responsible of creating, delivering and managing converged broadcast and telecommunications services. The next section examines a number of metadata languages candidates for describing the iTV services user interface and the schema language adopted in this project. A detailed description of the operation of the two tools is provided to offer an insight of how they can be used to de-skill and speed-up the process of creating digital TV user interfaces and applications for mobile terminals. Finally, representative broadcast oriented and telecommunication oriented converged service components are also introduced, demonstrating how these tools have been used to generate different types of services
