This way, we allow the media player to dynamically fix during playback the most common cases of subtitle synchronization misalignment that compromise users' watching experience. The benefit over current approaches lays in the usage of audio fingerprint annotations generated from the base audio signal as second-level synchronization anchors. Building on our previous efforts to address this problem, in this paper we formalize and validate a two-phase subtitle synchronization framework. The truth is that this process often involves a lot of trial- and-error because multiple versions of subtitle documents have distinct synchronization references, given that they are targeted at variations of the same audiovisual content. However, getting the subtitle document that gives satisfactory synchronization on the first attempt is like hitting the jackpot. Online subtitle databases allow users to easily find subtitle documents in multiple languages for thousands of films and TV series episodes. The discussion reflects on both activist interventions of people with disability and the industry standards. Although accessibility features may be available on broadcast television or DVD release, each of these forms of broadband-based television has either previously (Netflix) or currently (catch-up) stripped accessible functions to stream online. Netflix, which is not officially available in Australia, is often presented as the future of television, while catch-up services provide an example of the current roadband-based television paradigm in this country. ![]() ![]() ![]() This article interrogates the approach to accessibility taken by two case studies of broadband-based television: Netflix and catch-up TV. Government, industry and technical analysts describe digital television, particularly that delivered via broadband, as potentially enabling to people with vision and hearing impairments through the more widespread provision of accessibility features such as audio description and closed captions. Whereas entertainment has featured negatively in the broader NBN debate currently occurring in Australia, within the disability sector it has been recognised as revolutionary.
