2. General
• Any external command sent via Ethernet or serial will always be routed through the Cinema Controller to the Signal Backplane
and then on to the end device
• Cinema Controller contains a multi port internal Ethernet router, connected to all internal Ethernet devices.
• Once the Cinema Controller receives the command, it will convert it into the necessary protocol to control the end device.
• TI controls its own devices with commands to perform functions coming from the Cinema controller or from cinema server/IMe-
diablock.
• Decryption is handled by the Link decryptor or Mediablock.
• I²C communication between Fan Controller and Cinema Controller is used by the Fan Controller to send back error reporting
to Cinema Controller
• Cinema Controller receives error reporting and sends it to the Communicator and the log files.

The following steps happen :
• If decryption link is present; video is sent from server via HDSDI cables to the projector HDSDI board (or PCI express cable if
media block is inserted).
Video is decrypted on the Link decryptor board or Media Block and then sent to the Signal Backplane
•
• Video signal is sent to Integrated Cinema Processor
• ICP Board adds scaling, subtitle overlay, image cropping & applies all color correction. Also divides video signal into Red,
Green and Blue signals.
• Formatter applies any 3D frame rate multiplication if needed and turns signal into pulses to drive or cycle DMD mirrors.
• DMD's are reflecting the light provided by the prism back to the prism and reflect it through the lens towards the screen.
