My guess is the display in the video is designed along the lines of the two color CRT shown in the 1966 magazine shown in this thread.


Sony was know to be experimenting with Index beam televisions in the 70's. Maybe as early as 1967? I read they made a 30 inch index beam prototype set.

Two Watchman style CRT's could have been placed back to back in that box.

Two Index beam style color CRT's could have been placed back to back in that box in the video.

The last photo is a prototype type 8 inch color CRT from Sony. Infromation was published 1968. The other photos show the Sanyo and Sony index beam configuration.

In the video, you can see a lot of reflections. I think I see two different images displayed at the same time, but it's hard to say for sure.

Edit: To correct. From my research material, "Sony has been involved in the development of beam index CRTs since the Chromatron era and has started serious commercialization since the 1970s”.
