Need some help from you guys

Hey everyone, I'm new on these forums, but I was hoping someone could help me out. Currently I'm helping to categorize some footage of officiation of some basketball games. I am good with editing and stuff, but not so good with determining what calls are being made since I don't recognize all the hand signals. If anyone here could point me in the right direction (like a website or something) that would give me examples of the different hand signals, that would be really helpful. thanks in advance!
