For indexed formats, sizes of 1, 2, 4, or 8 bits per pixel can be selected. A 32-bit color
look up table is used to expand indexed modes into true color, including alpha values.
Predefined packed modes are available for YUY2 and UYVY formats. Other packed
modes can be selected by using one of the three variable input formats described
below.
Planar formats can be used to fetch pixel components from different locations in
memory. In semi-planar modes, a video field is defined by one plane for Y samples
and one shared plane for U/V. In full planar formats, each component is fetched from
a separate plane.
When processing a 4:2:2 or 4:2:0 input stream, the first sample fetched from memory
has to be a Y/U pair!
Variable Input Formats
In addition to the predefined fixed input pixel formats above, the MBS also includes
three variable input format modes for packed 4:4:4 and 4:2:2 pixel extraction. In these
modes, the pixel components can be extracted from programmable locations within
32- or 16-bit units.
Interpolation Filter
All horizontal video processing is based on equidistant sampled components. All
4:2:2 video streams, therefore, have to be up-sampled before being scaled
horizontally. The interpolation FIR filter used can interpolate interspersed or co-sited
chroma samples. Mirroring of samples at the field boundaries compensate for run in
and run out conditions of the filter.
