The main U-verse TV accessibility designs were for Closed Captions and ensuring WCAG contrast guidelines were met.
CEA-708 digital closed captions added user customization over font size/style/color/opacity, edge type/opacity, background color/opacity and window color/opacity. The quality of the implementation on other TV platforms at the time was quite awful. My goal was to create the best user experience and far surpass any other platform. Extensive research was done on font sets and regulatory requirements. Testing was performed in labs with input from closed caption professionals and accessibility experts. Colors, fonts and preview capabilities that were delivered provided customers an easy way to customize the display of closed captions.
