question: provide a detailed list of accessibility features that should be included in a television broadcast to ensure it is accessible to all viewers. the list should be at least five items long, written in english and lowercase, and include a brief explanation of how each feature assists viewers with specific accessibility needs.
answer: 1. closed captioning: this feature provides a text display of the spoken dialogue and other relevant audio cues, such as sound effects and music descriptions. it is essential for viewers who are deaf or hard of hearing, allowing them to follow along with the audio content of the broadcast.
  
  2. audio description: this involves an additional audio track that describes visual elements of the broadcast, such as actions, scene changes, and important visual details. it is particularly useful for viewers who are blind or have low vision, helping them understand what is happening on screen.
  
  3. sign language interpretation: a small window displaying a sign language interpreter can be included in the broadcast. this helps viewers who are deaf and use sign language as their primary mode of communication to fully understand the content without relying solely on text-based captions.
  
  4. adjustable font size and style for captions: allowing viewers to change the font size and style of captions can improve readability for people with visual impairments, dyslexia, or other cognitive disabilities, ensuring that the text is legible and accessible to a wider audience.
  
  5. customizable audio settings: providing options to adjust the volume of dialogue, background noise, and sound effects separately can help viewers with auditory processing disorders or hearing aids to customize their listening experience, ensuring they can hear and understand the content clearly.
