What is Active/Passive captioning?

If you are considering purchasing or have already purchased an institutional licence of Caption.Ed, you may be interested to learn about our active-passive licensing structure, which aims to provide efficient and cost effective captioning when dealing with large volumes of media and lots of users.


When you have many users viewing large volumes of institution owned media, then it become inefficient to attempt to transcribe media repeatedly again and again, each time a new user views a piece of media. 


Active - Passive captioning allows us to create captions, on-demand and only once, for each piece of media as viewed by a user. These captions are then stored against the media on your institutional dashboard, to be re-used by future users when they come to view the same media and require captions. 


As well as being much more cost effective, this also allows human editors to make edits to captions as required.


Active Captioning.

When a user views a piece of institution owned media for which Caption.Ed has not generated captions before, the Caption.Ed application will take the audio from the media, clean the sound, and transcribe the speech to text. We then process the text to enhance the accuracy further, and return it to the users screen. This is all done is a split second, however requires significant processing. 


As the same time we can store the captions generated, tagged against the media for which they were generated. These captions are then ready to be used by future users when viewing the same media. 


Passive Captioning

When a user views piece of institution owned media for which Caption.Ed has been used before. The captions provided to the user will be the stored captions, from the institutional account. For the user, the experience will be identical to when the media is being actively Caption.Ed, however for the institution this is much more cost effective when dealing with lots of media and lots of users.
