Text on Tap introduction

Text on Tap is the streaming platform of Text on Top. Where Text on Top is created to work on-site where the event takes place, Text on Tap allows remote viewers/participants to access the event. Examples of events are conferences, in church, at a funeral, (online) classes, (online) meetings, etc...

Online meetings by nature have a very low latency. Therefor the various solutions offered by Text on Tap are perfect to visualize the captions in real-time. However, events that are streamed via platforms like Twitch, Wowza, Youtube, Facebook, Ustream, ... have a latency of for example 10 seconds. This makes it harder to synchronize the captions. Additionally, these platforms offer Closed Captions in their players, allowing the users to optionally show captions. This is a convenient feature for the viewers.

The challenge is to ingest the live-produced captions into the video stream... that's where this Text on Tap Closed Captions encoder comes into play!
