Bitmovin Player Accessibility

Understanding the Web Content Accessibility Guidelines (WCAG)

The Web Content Accessibility Guidelines (WCAG) serve as the international standard for accessible web content. The WCAG covers various content types; images, video, audio, text, user interface presentation and underlying code. It classifies accessibility into three levels: A, AA, and AAA, representing basic to advanced accessibility functionalities respectively.

Significance of WCAG for Video Content

Implementing accessibility features into a playback experience helps ensure content publishers aren't excluding any potential customers from their service, given that WHO reports that approximately 16% of the global population have at least one disability. Beyond just providing a good quality of experience to all viewers, accessibility features also improve SEO and ranking as it contributes greatly to user experience.
