The Digital Cinema Initiative (DCI) has established specifications for a theater system that creates a common shell where regardless of the technology (projector, film, and now coming soon emissive screens) the experience experimented by the viewer is the closest to the one intended to be transmitted by the director. We will focus on this paper on the emissive screens. The theater system is composed of two major components, one is the player or Media Block and the second is the LED Screen. The main function of the Media Block is to provide a secure system environment within performing content essence decryption. In addition to this, the Media Block shall contain a security manager block, image decoding, audio processing and subtitle processing capabilities along with associated forensic markers. The function of the LED screen is to emit the proper chroma and luminance values providing the right environment where the viewer can have the best experience watching the content as it was a real life environment scene.
