1 Cinema circuit control
This block involves the CPU and memory circuit inside so that the setup data related to cinema (color setup/
definition change setup/ signal select information) can be stored in the internal memory.
When the cinema setup data are called up from the CPU PWB on NEC side through the RS232C, the signal
changeover and color setup data are converted and transmitted to the Processor, EFIB, and Formatter
boards.

2 Video signal conversion
The HDSDI signals (2 ports) and the DVI signals (2 ports) are received and converted into the parallel
signals.
The converted signals are transferred to the PROCESSOR Board via the MOTHER Board.
