Telepresence and immersion with high-definition digital displays: Background and future directions for research
More LessAbstractAs Ultra-High-Definition Televisions (UHDTVs) increase in size and screen resolution, viewers may choose to sit closer to them for a greater sense of immersion in programme or game content. The article reviews the evolution of the immersive aspects of widescreen motion picture formats such as Cinerama and IMAX and their influence on widescreen television displays. Potential areas for future research in telepresence and immersion are suggested with the advent of 4K and 8K UHDTVs and the development of ultra-wide-angle digital Head-Mounted Displays (HMD). Producers of widescreen motion pictures, television programmes and video games are creating content with the goal of increasing viewer immersion – and digital display technologies are evolving to replicate the theatrical motion picture experience in the home. Future research will be required to study the positive and negative immersive effects of these technologies as they are adopted by consumers.

Investigating the impact of television advertisement image quality on telepresence, attitude towards brands and purchase intentions
More LessAbstractIn an experiment manipulating the image quality of television ads, 127 participants watched television commercials in either high or low image quality. The participants rated each ad for their attitude towards the ad and purchase intentions. Additionally, sensations of telepresence and transportation were assessed. The participants who viewed the ads in higher image quality reported more positive attitudes towards the brands, and higher levels of telepresence. The implications are discussed.

Television white spaces: Learning from cases of recent trials
Authors: Hsien-Tang Ko, Chien-Hsun Lee, Jia-Huei Lin, Kay Chung and Nan-Shiun ChuAbstractWith the development of Super Wi-Fi technology starting in 2011, TV White Space (TVWS) trials have been conducted in the United States, the United Kingdom, Singapore and other developed countries, and applicable spectrum band, technology regulations and types of applications with regard to TVWS technology have been examined in this article. In many trials, Microsoft and Google have played a significant role. Supported by Spectrum Bridge, Microsoft set up spectrum databases in the UK’s and Singapore’s trials and voluntarily promoted TVWS applications in Kenya and Tanzania. This enabled Microsoft to provide broadband services in rural areas at a lower cost than previously possible in developing countries. Google also actively developed TVWS-related applications to increase broadband penetration and provide various innovative services, especially for the vertical markets. In addition, after Google obtained the authorization of the TVWS database from FCC on 28 June 2013, it became the third largest TVWS database provider in the United States. In order to improve the accessibility of broadband in Africa, Google supported the roll-out of TVWS broadband services in Republic of Liberia and Cape Town, South Africa. As a result, both Google and Microsoft have helped narrow the digital divide between African countries and developed ones.
