Quarter CIF
QCIF

   <communications, standard> (QCIF), a {video} format standard
   used in videoconferencing, that transfers one fourth as much
   data as {Common Intermediate Format} (CIF).

   QCIF is defined in ITU H.261 as having 144 lines and 176
   pixels per line, with half as many {chrominance} pixels in
   each direction.  QCIF is suitable for {videoconferencing}
   systems that use telephone lines.  The {codec} standard
   specifies that QCIF compatibility is mandatory, and CIF
   compatibility is optional.
