The NBA launched a video rulebook Thursday, a site where fans can watch detailed explanations of the league's rules.

The rulebook is "a place of reference for everyone with respect to how our games are officiated," Stu Jackson, the NBA's executive vice president of basketball operations, said.

It can be found at http://www.nba.com/videorulebook.

The site was about 1 1/2 years in the making, according to Jackson, and features approximately 150 plays.

"It's very difficult unless you've played the game at a very high level, or better yet officiated the game at a very high level, to understand the complexity of our rules strictly by reading them," Jackson said during a conference call. "By adding a written explanation as well as video examples, it just gives the person time to gain more knowledge about the rules or context, and hopefully a little bit more data and therefore education."
