Why being ADA compliant with closed captioning benefits everyone.

Closed Captions for broadcast television was one of the most successful and rapidly deployed and least controversial laws of all time. The Television Decoder Circuity Act of 1990 required all TV’s to support Closed Captions and shortly thereafter, CC was everywhere.

A decade later, media started to be important on the public Internet, and by 2010 the Twenty-First Century Communications Act included requirements for closed captions for internet video.  The U.S. Government had long required CC, via Section 508.  And in 2014, the U.S. FCC approved quality standards for CC.

In 2019, according to a recent study by Verizon 80% of closed caption users are NOT hearing impaired.

Adding captions to a video-on-demand has always been easy, but required a human operator and a lot of time.  Standards such as WebVTT and SRT make captions portable…get a video and the .vtt file and you have captioned video.

Making Closed Captions

It is very easy to add captions manually.  In a system like DEVOS, you upload the video, then play it as you listen:  start to type the words you hear and the video pauses; press enter and you have added a caption line and the playback continues.  In this way, you can caption a video in just a little bit more time than it takes to play the video.

Artificial Intelligence (AI)


With advances in AI and huge investments in things like Siri and Alexa, it is now possible to do a reasonably good job creating CC using only machines.  AI now has the ability to pick voices out of background sounds and to even identify different speakers.

But AI is still not at the near-perfect level.  What’s more, it may not understand technical terms (say Sphenopalatine ganglioneuralgia), and needs the assistance of a human to achieve near-perfect transcriptions.

That human assistance can come in several forms:  you can allow the machine to perform the transcription to captions and then manually edit it (if needed) in the DEVOS system, or you can use the built-in services of Ceilo24 to create near-perfect captions automatically.

Do You Need Closed Captioning ?

Closed Captions are not just for the hearing impaired. While you should take the high moral road while meeting regulatory requirements, studies show that captions are very useful for better comprehension of the content and for searching and finding the desired content.

Closed Captioning for Search

Caption Search

When you have thousands of videos, you can search by title, desciption, date, and entered tags.  But how can you find all the videos where someone mentioned “science” or “Discover Video”, or any other word for phrase?

The DEVOS system supports powerful search tool and you can rapidly find any video by searching the full text of the captions.

Live Captioning

The Discover Video DEVOS and Arcus system also support live captioning where you or a 3rd party may enter live text which is displayed in the live player.  For “IPTV” (TV Distribution applications), simply turn on the captions in the TV Set Top Box to display captions.
