Parameter
2.16.1 Triple Layer OSD
Three built-in layers of display screens accommodate triple display of channels, volume, etc., closed
caption, and sprite displays within layers 1 to 3.
The layer to be displayed in each block is selected by bit 0 or 1 of the OSD control register 2 for each
display mode (refer to Figure 2.16.7). Layer 3 always displays the sprite display.
When the layer 1 block and the layer 2 block overlay, the screen is composed with layer mixing by bit
6 or 7 of the OSD control register 1, as shown in Figure 2.16.5. Layer 3 always takes display priority of
layers 1 and 2.
Notes 1: When mixing layer 1 and layer 2, note Table 2.16.2.
2: OSDP mode is always displayed on layer 1. And also, it cannot be overlapped with layer 2’s block.
3: OUT2 is always ORed, regardless of values of bits 6, 7 of the OSD control register 1. And
Layer 3
besides, even when OUT2 (layer 1 and layer 2) overlaps with SPRITE display (layer 3),
OUT2 is output without masking.
