Mmr definition

A compression algorithm used in Group III and Group IV facsimile machines operating at 14.4 kbps or better and specified in ITU-T Recommendation T.6, MMR uses a two-dimensional compression technique that permits the transmitting modem to view and consider multiple lines of data during the encoding process. At 28.8 kbps, Group III machines can transmit a page in approximately four (4) seconds using a V.34 modem employing Quadrature Amplitude Modulation (QAM). At 33.6 kbps, Group III machines can transmit a page in about three (3) seconds using a V.34bis (aka V.34+) modem employing Trellis Coding Modulation (TCM). See also compression, encode, facsimile, Group III, Group IV, ITU-T, modem, QAM, T.6, TCM, V.34, and V.34bis.
