Abstract
Desde hace años asistimos a un continuo incremento de contenido audiovisual como vídeo en la Web, por ello que sea muy importante tener en cuenta requisitos de accesibilidad al incluirlo en la web para que todos los usuarios puedan acceder al contenido independientemente de sus características de acceso y contextos diversos de uso. Un contenido vídeo en la web debe ir acompañado de manera sincronizada de alternativas como subtitulado y audiodescripción entre otros, pero además el agente de usuario (reproductor) a través del cual los usuarios acceden debe ser también accesible. Como solución universal está el nuevo estándar HTML5 aun en desarrollo que proporciona algunas ventajas para la accesibilidad en lo que a contenido audiovisual se refiere. En este proyecto se presenta un estudio de estándares a cumplir para incluir contenido audiovisual en la Web, se valora si el nuevo estándar HTML5 da soporte y como caso de estudio se ha desarrollado un reproductor accesible en HTML5. _____________________________________________________________________________________________________________________
In recent years, we have seen a continuous increase of audiovisual content like video on the Web. It is very important to consider accessibility requirements when the video is included in the web page enabling users to have access to the content, regardless of users access features and diverse contexts of use. Video content on the Web must be accompanied by synchronized alternatives such as caption and audio description, furthermore the user agent (player) must be accessible too. A universal solution is the new standard HTML5, although it is still under development. It provides some advantages for accessibility as far as audiovisual content is concerned. In this project, a study is presented, which includes standards and requirements that need to be fulfilled when there is audiovisual content on the Web. A case study with a web accessible player has been developed in order to assess if the new HTML5 standard really offers accessibility requirements support.
