Up and Down Conversion
Up and down conversion in today’s facilities is required for interconnec-
tion between video formats that have different numbers of pixels/line,
lines/field, and in some cases, a different number of fields or
frames/second. This interconnection requires the use of up and down
format conversion devices.
Up conversion involves a three dimensional process for dealing with con-
version of a moving image. Moving images exist in three dimensions. The
horizontal dimension is made up of individual pixels. The vertical dimen-
sion is made up of lines contained in the field or frame. These exist in what
is referred to as the spatial domain. The number of fields or frames per
second is known as the temporal domain.
Generally, the process of up conversion deals with changing the number of
pixels and lines in a format (spatial domain). This process is a form of
sample rate conversion. One main issue with this process is that of resolu-
tion. Resolution cannot be created so the resolution of the original input
signal must be carefully recovered and passed to the up converted output.
