Display Mode Selection Table
The following display modes are provided for vertically interpolating
SIF resolution images to full resolution:
Display Modes and Vertical Filtering
Display Mode 0 - Progressive Luma/Chroma Line and Field
Repeat. In this display mode, the luma and chroma data remains
unfiltered. The luma data is treated as progressive; each line of luma
is displayed in both field times. The chroma data is both line and field
repeated. Each line of chroma is displayed twice in both field times
to achieve full-resolution 4:2:2.
Display Mode 1 - Progressive Luma Repositioning/Chroma Line
and Field Repeat. The luma data is treated as a progressive frame
and is vertically filtered using a bilinear interpolation filter to improve
luma positioning. The chroma data is both line and field repeated as
in mode 0
Display Mode 2 - Progressive Luma/Chroma Field Repeat
Repositioning. The luma data remains unfiltered and is treated as
a progressive frame. The chroma data is field repeated but filtered
using bilinear interpolation to improve chroma positioning.
Display Mode 9 - Progressive Luma Repositioning/Chroma Field
Repeat Repositioning. This display mode combines the luma
component of mode 1 and the chroma component of mode 2 to
achieve improved luma and chroma positioning. It is best suited for
frame based SIF images such as in MPEG-1.
