GNL.tv is an open source racecast system for Papyrus Nascar Racing 2003. It allows thousands of people to watch a NR2003 race live on the internet. This is the first step to providing the online racing community a true live experience watching other racers competing in their leagues.

A small server application connects to a NR2003 installation on the same computer and collects standings data and all car positions during the race. A PHP based webpage connects to the server application and displays the results. There is also a java applet that displays the car positions on a track map.

Originally developed for the german Virtual Racing e.V. league, GNL.tv has now been released as open source software. The goal behind this step is to provide a solid framework for building a sophisticated TV application with the help of the racing community that addresses all requirements for a unique watching experience.
