Abstract:
1. A method for use in a system in which information is transmitted, said method comprising the steps of: generating an extended code (COD) field representing a coding state of said information; including, in said extended code field, a bit stream indicating whether both a motion vector (MV) and a discrete cosine transform (DCT) value are not encoded, whether both the MV and the DCT are encoded, and whether only the MV is encoded, wherein said extended code field comprises at least two bits, and wherein the COD field having a bit value of “11” indicates that neither the MV nor the DCT value are encoded, the COD field having a bit value of “00” indicates that both the MV and the DCT are encoded, and the COD field having a bit value of “01” indicates that only the MV is encoded; and wherein where an error exists in a channel, only the values of “00” and “11” are used in an error allowable mode.
