All digital cinema About 100 theaters will use Sao Paulo-based Rain Networks’ KinoCast digital theater DRM software. Rain based its system on Windows Media 9 software with MPEG-4 video compression. ‘The MPEG-4 software can squeeze a feature film onto a file of just five gigabytes, 15 times smaller than the MPEG-2 technology presently used’ at one-third the $150,000 cost. It takes 20 minutes to distribute a 90-minute film over a VPN and the system avoids the costs associated with transporting physical copies to areas largely inaccessible by road – it can cost up to $750,000 for 500 copies of a Matrix-type blockbuster to be distributed.
