2. General
• Any external com mand sent v ia Ethernet or serial will always be routed through the Cinem a C ontroller to the Signal Backplane
and then on to the end device
• Cinema Controller contains a multi port internal Ethernet router, connected t o all inte rnal Ethernet devices.
• Once the Cinema Controller receives the comm and, it will convert it into the necessary protocol to control the en d device.
• TI controls its own devices with com mand s to pe rform functions coming from the Cinema controller or from cinema server/IMe-
diablock.
• Decryption is handled by the Link decryptor or Mediablock.
• I²C comm unication be tween Fan Controller and Cinema Controller is used by the Fan Controller to send back er ror reporting
to Cinema Controller
• Cinema Controller receives error rep orting and sends it to the Communic ator and the log files.

The following steps happen :
• If decryption link is present; video is sent from server via HDSDI cables to the projector HDS DI board (or PCI express cable if
media block is inserted).
• Video is decrypted on the Link decryptor board or
Media B lock and then sent to the S ignal Backplane
• Video signal is sent to Integrated Cinema Processor
• ICP Board adds scaling, subtitle overlay, image cropping & applies all color c orrection. Also divides video signal into Red,
Green and Blue signals.
• Formatter applies any 3D frame rate multiplication if needed and turns signal into pulse s 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.
