摘要： A video decoder receiving an encoded bit stream includes a header decoder which receives the encoded bit stream, a variable length decoder connected to the header decoder which receives the header decoded data, a quantizer and compensator connected to the variable length decoder, for, during backward decoding, performing inverse quantization, transformation and motion compensation of the variable length decoded data. The inverse quantization, transformation and motion compensation of the header decoded data is done consecutively to provide complete decoded data till a first point in the backward direction such that the first point is either the error point or a point before the end point of the macroblock containing error detected in the forward direction and the output buffer is connected to the quantizer and compensator for storing complete decoded data, thereby eliminating the use of intermediate buffer for storing variable length decoded data during backward decoding and reducing the number of computations.

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： 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.
