(communications, standard)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.
