AbstractA high efficient encoding/decoding system has processor for processing a sub-macro block having at least one collection of blocks as an encoding unit of input data, and a macro block having a macro block length data for indicating the length of the macro block itself in its head position and at least one of the sub-macro blocks. The collection of blocks in the sub-macro block includes a first passage for a variable length data having at least one collection of data obtained by performing a variable length encoding for every block of encoding unit on the input data, header information associated with the variable length data and a sub-macro block length data for indicating the length of the sub-macro block itself, a second passage for an adjustment bit data and a length data indicating the length of the adjustment bit data itself, and a third passage for a correction directing signal, thus for transmitting a data for selecting at least one of the three passages by embedding the selecting data in a coefficient based on an encoding characteristics of the variable length data.
