RGB input format

Two data processing methods exist for RGB input video capture functionality:

processing of Native RGB

processing by converting RGB into YUV422 using the internal RGB preprocessor.

The RGB input function is suitable for relatively fast, non-interlaced video signals but de-interlacing is

not available in this mode. The maximum input rate is 66Mpixel/sec. Each RGB component is 6 bits

Note: To use Native RGB mode, set the NRGB bit of the

(1) RGB Input Signals

The RGB video capture input signals are not assigned to dedicated package pins. These pins are

shared with other device functions (multiplexed, check MUX Group #5).

Note 1 : Input pins are shared with the ITU656 input and memory data bus.

Note 2 : The VIS bit of the

ITU656/601 or RGB) is used.

(2) Captured Range

In comparison to the embedded sync code method used in ITU656 input mode, the capture range

in RGB mode is specified by register parameters, as shown below:

a) RGB input capture mode: Set the RGB666 input flag (VIS) in the

For Native RGB mode, set NRGB=1 in the

b) HSYNC Cycle: Set the number of HSYNC Cycles in RGBHC.

c) Horizontal Enable area: Set the area start position and picture size in RGBHST and RGBHEN.

d) Vertical Enable area: Set the area start position picture size in RGBVST and RGBVEN.

The capture area is defined according to the following parameters (each parameter is set

independently in the respective register):

Clock for RGB input

Red component value

Green component value

Blue component value

Horizontal sync for RGB capture
