An MPEG video CODEC includes a variable length decoder to a video coder with respect to an MPEG-2 profile. The MPEG video CODEC further includes a controller which controls both a signal sequence and a signal input/output function when a function of the MPEG video CODEC is converted to a decoding-mode and a coding-mode. Accordingly, the MPEG video coder and MPEG video decoder can be embodied as a single system. The MPEG video CODEC comprises a coding/decoding mode generator for detecting whether a mode signal inputted from an input terminal is a coding-mode, or a decoding-mode, and generating a corresponding mode control signal; a coder/decoder selector for selectively converting a routine of a coded bit stream, according to a corresponding mode control signal from the coding/decoding mode generator; and a coder/decoder for selectively coding or decoding a bit stream selected by the coder/decoder selector, and then transmitting the bit stream to a storage element, or to a displayer.
