Adjustment Data by Geometry
Some registers contain data that is stored in a single memory location.
Other registers have multiple memory locations. These multiple
memory registers have data stored by picture geometry.
There are seven picture geometry modes
1. Normal – 4:3 aspect ratio picture with black borders.
2. Full - 4:3 picture stretched to fill the 16:9 picture tube.
3. Caption – Full picture but compressed on bottom to see lettering.
4. Zoom – 4:3 picture expanded horizontally and vertical to maintain the
aspect 4:3 ratio of the picture.
5. Wide Zoom – Full picture but equally compressed on top and bot-
tom.
6. SD – DTV – Standard definition digital reception presented in the
transmitted 4:3 or 16:9 aspect ratio.
7. HD – DTV – High definition digital reception presented in the trans-
mitted 16:9 aspect ratio.
When the geometry is changed, the data may be different for each of
the pictures. For example in the HSIZ (horizontal size) register within
group SDA9361, the data for a normal picture and a full picture will be
different because the pictures are of different widths. However, it is
expected that the horizontal data to be the same between the full and
caption geometry modes since the horizontal width is the same (only
the vertical linearity is different).
