Understanding the Basics of Closed Caption (CC) Technology

Closed caption (CC) technology has revolutionized the way we consume audiovisual content. Whether it's a television show, movie, or online video, closed captions provide a textual representation of the audio, enabling individuals with hearing impairments to understand and enjoy the content. In this article, we will explore the basics of closed caption technology and its significance in today's digital world.

What are Closed Captions?

Closed captions are a visual display of the audio elements in a video or audio file. They typically appear at the bottom of the screen and include dialogue, sound effects, and other relevant audio information. The purpose of closed captions is to make audiovisual content accessible to individuals who are deaf or hard-of-hearing. They can also benefit non-native speakers, individuals in noisy environments, and those who prefer to read the text while watching the video.

How Closed Captions Work

Closed captions are created using special file formats, such as SubRip Subtitle (SRT) or WebVTT (VRT). These files contain time-stamped text along with additional information, such as placement, formatting, and styling. When a video is played, the closed caption file is synchronized with the audio, ensuring that the corresponding text appears on the screen at the appropriate time.

To create closed captions, a transcription of the audio is first generated. This can be done manually by typing out the dialogue or by using automated transcription tools. Automated transcription tools, such as PlainScribe, can save time and effort by converting audio into text more quickly and accurately.
