You know how in the beginning of every World Poker Tour episode, there's a small video about the rules of Texas Hold'em poker and how the game progresses? Similar video could be made about Calibur and show it before a tournament, nothing too detailed, just short and to the point. Just mention how it's a four button game, what the different flashes (white, blue, yellow, green etc.) are, how to gain and use meter, what the flashing life bar means and how important ring position is. And like I said, nothing too detailed, it's not supposed teach people how to play, but show them how to follow a game of Calibur.
