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： An output coding apparatus includes a coder for coding an inputted bitstream to an error correction and/or detection code composed of information bits and check bits; and a bitstream assembling section for assembling an outputted bitstream by inserting a synchronization code at any one of a plurality of synchronization code insertion positions previously determined in the outputted bitstream, arranging the information bits at any desired positions of the bitstream, and by arranging the check bits at positions other than the synchronization code insertion positions in the bitstream. Therefore, when the coding apparatus is combined with a resynchronization method using both an error correction and/or detection code and a synchronization code, it is possible to solve a problem caused by pseudo-synchronization or synchronization-loss pull-out or step-out due to erroneous detection of the synchronization code.

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.

摘要： A video encoding apparatus is provided with a resolution converting section, an encoding section, and a transmitting section. The resolution converting section enlarges or reduces a binary picture which represents the shape of an object. The encoding section encodes a binary picture reduced by the resolution converting section. The reduction ratio used by the resolution converting section is encoded, and the transmitting section transmits this encoded reduction ratio along with encoded data on the binary picture. The amount of encoded data produced from the encoding section is controlled by changing the enlargement/reduction ratio used by the resolution converting section.
