[media-and-entertainment] Use case description: responsive grafics synced with video (#35)

== Use case description: responsive grafics synced with video ==
I'd like to describe a use case we have right now that could make use of the [DataCue proposal](https://github.com/WICG/datacue/blob/master/explainer.md).

We are aiming to install a workflow for responsive grafics in VoD content. The aim is to transport grafical elements/animations separately to the client device and dynamically compose the final image in the player application. I'm talking about typical TV grafics here, including even a broadcasters logo. One of the main scenarios where this seems promising for us is adapting grafics for a portrait mode playback on mobile devices. In some cases, the syncronisation between the video image and the grafics must be very accurate. I guess the use case is similar to subtitles in that regards.

There is a plattform called [Singular.Live](https://www.singular.live/) that already does something like that on a proprietary basis. I'm sure there are also other companies/solutions.

But I don't know of any (implemented) specification that allows synchronising the grafic playback with an HTML5 video element. We could use a TextTrack of course. The DataCue seems to provide exactly that. Has such a use case been discussed already in this group? 

Of course, if somebody is working on a similar topic, it would be great to share experiences here.
