DDC transmission with cache function
The DVIVision system supports Enhanced-DDC (Enhanced Display Data Channel) to
read out the data from the monitor that is connected to the computer module
(DVIVision-CON) and transmit them to the computer. This data includes informa-
tion regarding the preferred resolution and the supported monitor frequencies.
A cache function is integrated in the system so that the computer that is connected
to the computer module (DVIVision-CPU) has access to the actual capabilities of
the remote monitor already during the boot process. Even if the computer module
or the user module are turned off or if the devices are not interconnected, the proper
-
ties of the most recently connected monitor or a default data block are provided in
the DVIVision system.
The DDC information of the monitor are basically transmitted one-to-one. In case,
the DVIVision system determines that the display cannot be read without errors or
that the entries are invalid, the information are completed or corrected
