Video coding according to H.263 is for communication of audiovisual services with data rates from 128 kbit/s to 2 Mbit/s. The H.263 codec is an extension ofH.261 and partially replaces it.

H.263 is backward compatible with the Quarter Common Intermediate Format( QCIF) and optionally also with the CIF representation format and SQCIF (Sub-QCIF) of the H.320 standard.
