With these components, blending operations such as the following are possible:

One input to P-Values output:
- Pixel Presentation (0008,9205) has a value of MONOCHROME
Figure XXX.6-1. One Input To P-Values Output
One input to PCS-Values output:
- Pixel Presentation (0008,9205) has a value of TRUE_COLOR
- One Input -> RGBA component (Component Type (0070,1802) = ONE_TO_RGBA)
Figure XXX.6-2. One Input to PCS-Values Output
Two inputs to PCS-Values output:
- Pixel Presentation (0008,9205) has a value of TRUE_COLOR
- Presentation State Classification Component Sequence (0070,1801) has two items:
  - One Input -> RGBA component (Component Type (0070,1802) = ONE_TO_RGBA)
  - One Input -> RGBA component (Component Type (0070,1802) = ONE_TO_RGBA)
- Presentation State Compositor Component Sequence (0070,1805) has one item:
  - RGB Compositor component
Figure XXX.6-3. Two Inputs to PCS-Values Output
Three inputs to PCS-Values output:
- Pixel Presentation (0008,9205) has a value of TRUE_COLOR
- Presentation State Classification Component Sequence (0070,1801) has three items:
  - One Input -> RGBA component (Component Type (0070,1802) = ONE_TO_RGBA)
  - One Input -> RGBA component (Component Type (0070,1802) = ONE_TO_RGBA)
  - One Input -> RGBA component (Component Type (0070,1802) = ONE_TO_RGBA)
- Presentation State Compositor Component Sequence (0070,1805) has two items:
  - RGB Compositor component that combines the outputs of the first two classification components into one RGB
  - RGB Compositor component that combines the outputs of the previous RGB Compositor and the third classification component into one RGB. This RGB Compositor internally sets the missing Alpha to (1 - Alpha-3) since there is no Alpha output from the previous RGB Compositor

The Volumetric Presentation State Display Module provides functionality equivalent to the Enhanced Blending and Display Pipeline defined in Section C.7.6.23 “Enhanced Palette Color Lookup Table Module” in PS3.3:
- For P-Value output:
  - Pixel Presentation (0008,9205) has a value of MONOCHROME
  - Presentation LUT Shape (2050,0020) is present

- For PCS-Value output:
  - Pixel Presentation (0008,9205) has a value of TRUE_COLOR
  - Presentation State Classification Component Sequence (0070,1801) has two items:
    
    One Input -> RGBA component (Component Type (0070,1802) = ONE_TO_RGBA)
    
    Two Input -> RGBA component (Component Type (0070,1802) = TWO_TO_RGBA)
  - o Presentation State Compositing Component Sequence (0070,1805) has one item:
    
    RGB Compositor component
