6. Built-in OSD block
This function can do OSD (On Screen Display) on the image data after adjusting image quality.
The amount of the expression per pixel can be selected from 16 indexes (4 bits: CLUT4) and 256 indexes (8 bits:
CLUT8). The color pallet of the index can set alfa 4-bit of blending coefficient and 8-bit of green, blue, and the red.
Displayed character and icon, etc. need to set the
αGBR color to the color pallet and transmit the BMP data in the
state of CLUT 4/8. The drawing engine is built-in, besides, it is possible not only to draw the transmitted BMP data
to SDRAM but also do the rectangle drawing (including point and line drawing) and copy inside SDRAM.
7. Output/I/F/others
7-1. Matrix conversion
The following Matrix conversion is possible for 2 systems after digital and analog input are selected.
YCbCr to RGB
YPbPr to RGB
YPbPr to YCbCr
RGB to YCbCr
7-2. Output format
Output is possible with the following format.
Digital RGB (30-bit/24-bit)
Digital YCbCr (30-bit/24-bit)
7-3. Clamp control
This can generate clamp signal in external LSI or in the built-in AD converter. In addition, it can generate
optional pulse(“H”, “L”, “Hi-Z”) by comparing to the threshold value in the inside the LSI.
7-4. SDRAM interface
This built-in SDRAM interface, the system can be made up easily by connecting
64Mbits SDRAM (512word
× 32bit × 4bank) 1 piece or 128Mbits SDRAM (1024word × 32bit × 4bank) 1 piece
in directly. In this case, more than“-60” speed grade of SDRAM is recommended.
7-5. External OSD interface
This allows the interface with external OSD microcomputer using input pin 41 to 45 and output pin 36 to 38. It
can display closed caption and teletext data.
7-6. I
2C interface/3 wire bus interface
It basically controls the internal register using I
2C interface.
The slave address can be a switch by controlling pin53 (I
2C SEL) according to the system.
The slave address is as follows.
I
2CSEL “L” “0111000+(R/W)”
I
2CSEL “H” “0111001+(R/W)”
A part of register can be controlled by 3wire bus interface as well.
