The FORscene Linux proxy box can capture 24 hour video streams locally. FORscene's efficient navigation then gives quick access to material relevant for review and editing, which is uploaded in real time as required. By using client machines for the CPU intensive tasks of compression and playback, the FORscene proxy box scales well to multiple 24-hour TV channels.
