Output signal, frame AB at time n, progressive
The table below describes the different scan rate conversion algorithms and the corresponding
raster sequences (see also
Principles of scan rate conversion
on page 55). The delay between the
input field and the corresponding output fields depends on the OPDEL parameter and the default
value for the delay is an half input field.
The INTERLACED signal can be used for AC-coupled deflections. Depending on the parameter
INTMODE the value of this signal will be generated. The table below shows also the definition of
this signal.
