ABSTRACT:
Digital data, such as audio data is coded by encoding apparatus, into a format of fixed-length multi-bit data words. At least one bit in the same predetermined bit position in each data word is a specific information data bit, such as channel status information or user information. A plurality of the specific information data bits from a corresponding plurality of successive data words respectively form a specific information word. Each specific information word contains a synchronizing signal, and the length of the specific information words is variable. A decoder decodes the encoded digital data.
