What are closed captions and how do they differ from subtitles?
Closed captions are a type of accessibility feature that provides a visual representation of the audio content in a video, including dialogue, sound effects, and music. They are called “closed” because they can be turned on or off by the viewer, as opposed to “open” captions, which are always visible. Closed captions are typically used to assist viewers who are deaf or hard of hearing, as well as those who may be watching videos in a noisy environment or with the sound turned off. They can also be helpful for language learners or viewers who want to improve their comprehension of the video content.
The main difference between closed captions and subtitles is that subtitles only provide a translation of the dialogue, whereas closed captions include a more detailed representation of the audio content. Subtitles are typically used in foreign language films or videos, where the goal is to provide a translation of the dialogue for viewers who may not speak the language. Closed captions, on the other hand, are designed to provide a more comprehensive representation of the audio content, including sound effects, music, and other non-speech elements. This makes closed captions a more useful tool for viewers who rely on them to fully understand the video content.
What is the history of closed captions and how have they evolved over time?
The history of closed captions dates back to the 1970s, when the first closed captioning systems were developed in the United States.
