The aim of this research project is to fully automate sign language for broadcasters’ content using realatars. Term of the project: 2017 to 2021.


Deaf individuals often have difficulty reading. Subtitles are therefore only of limited use to them. A sign language translation is more helpful. Many public-service TV broadcasters provide this service using expensive human sign language interpreters.

Aim and implementation of the Content4All project

  • Development of so-called “3D reala(va)tars”, using artificial intelligence (AI) and in-house developed technologies to automatically convert speech (audio signals) into subtitles (text) and then into realistic-looking people (realatars).
  • These realatars appear in special glasses or virtually in your living room.
  • This is known as “telepresence outside of the TV”.
  • The focus is on broadcasting companies that can save huge costs with a solution like this.

The project phase has been completed and the test phase is now getting underway.

The research project won the NAB Technology Innovation Award 2020.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 762021.
