First Time

Flexibility for many viewers comes from digital technologies and their interaction with television broadcasting. Significantly, as television is switched to digital transmissions, viewers with disability have the potential to experience flexibility in the form of accessibility features such as audio descriptions, captions, lip-reading avatars, signing avatars, spoken subtitles and clean audio. This flexibility may in fact provide some people with access to television for the first time. This exploratory study reports results from an online survey of Australians with disabilities conducted during the final months of the simulcast period before analogue signals were switched off in 2013. While captioning emerged as the most desired accessibility feature, differences surfaced when the data were broken into specific impairment types. This article highlights the importance of digital flexibility specific to impairment type, and locates people with disability as a significant group to consider as more changes take place around digital television broadcasting via the NBN.

Degree Of Innovation

Over the past decade, a major policy and regulatory problem for governments in Australia and elsewhere has been the implementation of strategies to switch from analogue to digital television broadcasting systems. Despite extensive debate, the transition to digital broadcasting remains fraught. What seems to be a technical matter conceals a range of intractable social, economic and cultural policy decisions. This article explores some of the challenges of digital television through the prism of an earlier, and often overlooked, transformation of television, namely the consumer-driven uptake of what can be called the ‘new television technologies’ of the 1970s and 1980s. These earlier forms of new television help to highlight several arguments: that television was not a stable object prior to digital broadcasting; that the connections between television and broadcasting have been contingent and provisional; and that a remarkable degree of innovation, disruption and adaptation has occurred at the fringes of the broadcasting system, leading to the creation of new audiovisual economies on the boundaries of the household and the market. The article then considers some examples of the ways in which this ‘household sector’ is developing as a new policy problem.
