Abstract

TV can be regarded as the most far-reaching media in Brazil. Its presence is noticed in 90% of Brazilian homes and it is the main source of information for a major part of the population. The moment of definition and consolidation of the digital TV technology provides us with a unique opportunity for analyzing and discussing this media accessibility. Making sure that TV contents and devices are flexible enough so that people are able to perceive, understand and interact with them is a main asset for its use and an essential requirement for the democratization of information via TV broadcasting. This paper analyzes interactive digital TV accessibility in informal, formal, and technical levels, considering the Brazilian context. In addition, it presents recommendations to design accessible interfaces by referring to the W3C guidelines 2.0 for Web accessibility and specific recommendations for iDTV.
