Live Closed Captioning

I am getting requests to provide closed captioning for selected live events for our company. Our CDN can accommodate us, but only with the dual browser style of live CC. That style is an extra browser that Pops up on top of the stream window with the text. The style that mgmt here wants is Embedded. its inserts a black strip running at the top or bottom of the frame inside of the image with the text.
Has anyone here done this type of CC? I'm not finding much when I do a google search. maybe I am using the wrong terms? Our CDN is West Conferencing Services.

I not sure what you mean by a vision mixer, But are you referring to adding the captions as part of the video feed to the live stream? in a PIP somewhere on screen?That would be an "overlay" style of CC. it cant be turned off/on if viewers don't want the captions. We are looking for the "embedded " style that is inserted on a line of the player's code, I'm not sure if thats' the correct term. looking the Wowza site is see reference to: In-stream (embedded) CEA-608 captions (Line 21 captioning)
