Caption types

The are different types of captioning. Not all types of captioning fulfill all accessibility requirements.

  . Using closed captions is optional. Users can plough them on or off with their video player or other controls. Closed captions for video on goggle box are read by a decoder that is part of the hardware of all goggle box sets sold in the United States. Closed captions for video on the web are read by a media player, if it supports closed captions. Not all versions of media players support closed captions. Closed captions are not part of the actual video stream and exist in a separate text stream.

  Users who want to access closed captions need to understand how to plow them on from their televisions or media players. Include instructions for users in your form.

Open up captions are non subject to dissimilar media actor features. Users do non have to know how to turn the captions on. A disadvantage of open captions is that if the video is compressed, there can be a loss of quality and readability. They can too exist distracting to some users.
• Audio Clarification: Adding a written description of sound furnishings such as "floor creaking" or "glass shattering" provides a richer experience for viewers. Audio descriptions are part of open or airtight captions. They can fill in missing information a narrator fails to provide. For example, if a narrator says, "As you can see, the three master points support the conclusion," simply doesn't say what those three chief points are, audio description provides the missing information in the captions.

  The easiest way to avoid requiring audio clarification in the instance is to have a storyboard that the narrator follows that details visual information out loud.

• Existent-time Captions: Taking place during a synchronous outcome such as streaming video or a Blackboard Collaborate session, existent-time captioning, sometimes referred to every bit real-time text, is a transcription service similar to TDD/TTY for telephones. Transcription services are separate from Blackboard Learn. There is usually a toll for the service and the service needs to be arranged in advance of the outcome.
• Subtitles: Translating just dialog and non including sound effects or other description, subtitles assume that viewers can see and hear. Only spoken dialog is captioned and often translated into a unlike linguistic communication.
