News Ticker Need Help on Mouse hover pause

News Ticker Need Help on Mouse hover pause

I have created a news ticker, I need to pause the ticker on mouse hover. Here goes my code. 


              <script>
              function tick()
                  {
                      $('.ticker li:first').slideUp( function () { $(this).appendTo($('.ticker')).slideDown(); });
          }
               setInterval(function(){ tick () }, 5000)
             </script>

                  <ul class="ticker">
                        <li>
                              <h5 class="simple-title leftfloat rm20 black">De Ferno Kumbuki</h5>
                              <p class="small"><i>"dksfjbgvjsddgjndgljnjln"</i></p>
                        </li>
                        <li>
                              <h5 class="simple-title leftfloat rm20 black">Araandum Paranju</h5>
                              <div class="clear"></div>
                              <p class="small"><i>"qwertyuiopolkjhx."</i></p>
                        </li>
                  </ul>

Thanks in Advance...
