摘要： A coding and/or decoding system includes: a code-word table for storing therein a plurality of code words, which are capable of being decoded both in forward and backward directions and which are formed so that delimiters of the code words are capable of being identified by a predetermined weight of the code words, so that the code words correspond to different source symbols; an encoder for selecting code words corresponding to inputted source symbols from the code-word table; and a synchronization interval setting part for preparing coded data every predetermined interval using the code words selected by the encoder and for inserting stuffing codes capable of being decoded in the backward direction. Thus, it is possible to decrease useless bit patterns to enhance the coding efficiency by smaller amounts of calculation and storage, and to decode variable length codes both in the forward and backward directions even if the synchronization interval is set every interval using the stuffing bits.

摘要： Encoded data using reversible variable length code words is input to a forward decoder (123) to be decoded in the forward direction. When an error is detected in the encoded data in the forward decode processing, backward decode processing is started by a backward decoder (126). A decode value determination unit (125) determines a decode value by using the forward and backward decode results and the error detection positions in the encoded data in units of bits and syntax which are respectively detected in the forward decoding and the backward decoding.

摘要： In an information transmission method, error robustness is provided for the bit stream itself so that decoding processing can be properly performed even in the event of an error in important information such as header information. A bit stream reconstruction circuit (107) in an encoding apparatus adds sync signals to the heads of encoded data streams, which are encoded by an encoder (103), in certain bit stream units, and then inserts designation information in each bit stream by using a designation information insertion circuit (106). Each designation information indicates the addition of information for reconstructing important header information. By inserting the designation information in the bit stream obtained, reconstruction information can be added to the bit stream. Even if, therefore, an error is introduced into the header information, and the information cannot be used for decoding processing, the decoding processing can be properly continued by using the new reconstruction information designated by the designation information as a substitute.
