New movies from content providers are often made available on the Internet before being launched in the cinemas. Pre-released movies like DVD Videos for journalists are the main reason for this situation because some journalists seem to make these movies available to the Internet users. However, this causes significant harm to the content providers. According to the invention, the pre-releases are still DVD Videos or other conventional video formats but the playback of such encoded video signal is not possible using only a conventional DVD player or DVD player software because the playback requires additional hardware. An additional box (CP splitter box) splits the original video signal into two different video signals to be projected using two different beamers (A, B) which both are required for generating the whole video content. The beamers have different locations each with a different angle to the silver screen, and each beamer generates only a part of the video.
