The 21st Century Communications and Video Accessibility Act requires all Internet programming that previously aired on television with captions to have captions online, as well. The values of captioning include: - Accessibility for deaf and hard of hearing - Accessibility for ESL viewers - Flexibility to view anywhere, such as noisy environments or offices - Search - Reusability - Navigation, better UX - SEO/discoverability - Used as source for translation Watch the slideshow for a how-to guide for captioning your videos with 3Play Media.
