Digital Television

Television broadcasting and receiving technology that uses digital signals rather than analogue, enabling additional features such as interactive services, electronic programme guides, on-demand content, and multiple channel packages. Digital television accessibility is a significant concern because the transition from simple analogue TV to complex digital systems introduces new barriers for older adults and people with disabilities: multiple remote controls, on-screen menus with small text, interactive features requiring multi-step navigation, and set-top boxes that add operational complexity. Accessible DTV design requires attention to remote control usability, on-screen text size and contrast, audio description, subtitles/captions, and simplified navigation for users with cognitive, visual, or motor impairments.
