television technologies as well as other applications.

Video experts often compare SIF to another common format
called Common Intermediate Format (CIF). Other common formats include QCIF and
SCIF. Each of these have their own video resolution and other attributes. For
example, with SIF resolution at 352 × 240, and CIF resolution at 352 × 288, the
output of these two formats is not radically different. Developers and
engineers may also look at elements like interlace and frame rate.
