And another version going back to the circles for jersey colors. I also used different teams this time. And I show an example for a yellow card. This little infos would slide to the side right after the the action happened (Goal, card, ...) and would disappear after a few seconds.
About the screen resolution: This is of course designed for full HD TV. And again, it's just a little idea/concept. If this was a real project I would go and do user testings on a real TV. ;)
