Free On-line Dictionary of Computing:
quarter cif
(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.
