16. DDC INTERFACE
The monitor typically includes a number of user controls to set
picture size, position, color balance, brightness and contrast.Fur-
thermore, to optimize some internal setting for different display
modes, the timing characteristics should be acquired by the con-
trol side. In these days, it is getting popular for these controls to
go to PC host. Therefore the communication between monitor
and host becomes issue.DDC1, DDC2B, DDC2B+, and
DDC2AB(ACCESS.bus) emerge as a standard for monitor inter-
face. A transmitter clocked by incoming VSYNC is dedicated for
DDC1 operation. An I2C interface hardware logic forms the ker-
nel of DDC2B, DDC2B+, and DDC2AB. An address pointer,
with post increment capability is employed to serve DDC1,
DDC2B,DDC2B+ and DDC2AB modes.
The conceptual block diagram is illustrated in Fig. 16.1
