Accessibility
• (6) Support Universal Accessibility to Streaming Media:
• Effective design of streaming media content will need to consider and address the provision of
• closed-captioning (for persons with hearing impairments), descriptive audio tracks (for persons
• with blindness) and other Web accessibility components. In addition to aiding persons with
• hearing impairments, closed captioning also has the potential to provide improved indexing and
• searching of content
