ĀN ĒXAMPLE is "An Example".

Uppercase characters are represented using a bar/macron over the top - I was a bit slow to work that out and I don't remember seeing that convention before.

Edit: pulvinar said "It's clearly a vector display". You can see a graph using vector lines at 24:13, zooming at 20:50, and there's graphic lines mixed with text at 28:36.

IIRC, it was a vector display in front of a raster camera. The same arrangement was used throughout the Gemini and Apollo mission control and up to the early shuttle program - images would be rendered in the RTCC (real-time computer complex(?)) and piped to the slow-scan CRTs in the panels. At the panel the operator could select which video stream they wanted to see. One of the streams was a "channel guide".
