10/8 second backcourt violation
 

what are the rules for backcourt violations in terms of an 8 second or 10 second count? If a timeout is called does the count continue where it left off or reset???? if the the ball is deflected out of bounds by the defender is the count resetted. please clarify....thanks

8 seconds refer to FIBA, so I'll give the relative rules.

The count begins when there is player control in the court; if the ball is deflected out of bounds (or if play is stopped because of an injury to a player of the team in control) the count is not reset: the official will show the number of seconds remaining before handing the ball for the throw-in. The same happens if there is a held ball and the AP favors the same team. However, if we are in the last two minutes of regulation or overtime and the team in control is granted a time out, the throw-in will be at the division line and, if the ball is passed in the back court, there will be a new 8 second count.

There's no possibility to grant a time out during a live ball.

NFHS Case Book
 

9.8 SITUATION C: After A1 has dribbled for nine seconds in A’s backcourt: (a) A1 requests a time-out; or (b) B1 deflects the ball out of bounds. RULING: In both (a) and (b), Team A will have 10 seconds to advance the ball to frontcourt following the throw-in if a player of Team A gains control in A’s backcourt.

If you are not from the USA, then the previous post should help you.
However, if you are from the USA, then you need to know that the NBA uses an 8 second count in the backcourt, but that the HS and NCAA levels use 10.

The NBA count is what is known as a hard count, meaning that it does not reset under the conditions which you noted. The NBA also has a variation for the last 2 minutes of the 4th quarter and extra periods.

The 10 second count under NFHS (HS) and NCAA (college) rules is a soft count and does reset when there is a violation or time-out.
