You are right.
I compared the performance between CSS animation and SVG animation before.
At least in case of ticker, SVG animation was completely useless.
But it's not a matter of the technology nor the spec.
It's a matter of the implementations of browsers.
In the future, the implementations of SVG animation might be improved.

I think so, too.

Thanks for your understanding.
At least I strongly push the Web (i.e. HTML/CSS/JavaScript).
But it's true that there are SMIL/SCXML supporters in signage industry.
We should hear all demands equally at this time.

Absolutely. Yes.
This business group is looking for people who are familiar with
signage industry and web technologies like you.
We hope that you will be joining this group.

BTW, do you have any actual web-based signage contents,
by any chance?
If so and we can view the contents in web browsers from anywhere,
could you tell us the URL?
It should be helpful for us.

Cheers,
