An image decoding apparatus decodes transmitted compressed image data. The apparatus includes a receiving buffer for temporarily storing the compressed image data, a decoder for reading compressed image data stored in the receiving buffer corresponding to proceeding conditions of a decoding process and decoding image data of one frame within a period equal to the frame period of the image or within a period shorter than such frame period, and an eliminating circuit which is providing in the receiving buffer to supply the compressed image data to the receiving buffer after eliminating invalid code to prevent underflow of data in a send buffer provided in an image coding apparatus.

The horizontal address and the vertical address of a picture image are arrayed at the lower and upper order sides, respectively, and allocated to a lower order side column address and an upper order side column address of the synchronous DRAM employed as a picture memory, respectively. A bank switching address is allocated between the upper most bit of the horizontal address and the lower most bit of the row address to enable data to be read continuously to achieve high-speed accessing and improve the utilization efficiency of the data bus.

Moving picture decoding device

Error start codes are inserted, by means of error start code inserting section (12), between transfer units of intra-frame coded data starting from a start code reproduced by reproducing section (11) from picture recording medium (10) to decode intra-frame coded data on the basis of the error start code and the start code at decoder (14).

Picture signal decoding method and picture signal decoding apparatus

An encoding and decoding apparatus and method which has the primary benefit over the prior art of not requiring storage of the nonlinear sequence of numbers representative of the quantization characteristics. The hardware required for quantization is reduced and inverse quantization may be achieved using shifting operations and a multiplier of up to half the scale compared to conventional encoding/decoding methods and encoding/decoding apparatus.

Picture signal encoding method and apparatus and picture signal decoding

A digital video signal that has been encoded using motion-compensated prediction, transform encoding, and variable-length coding, is decoded using parallel processing. Frames of the video signal are divided into slices made up of a sequence of macroblocks. The signal to be decoded is slice-wise divided for parallel variable-length decoding. Each variable-length-decoded macroblock is divided into its constituent blocks for parallel inverse transform processing. Resulting blocks of difference data are added in parallel to corresponding blocks of reference data. The blocks of reference data corresponding to each macroblock are read out in parallel from reference data memories on the basis of a motion vector associated with the macroblock. Reference data corresponding to each macroblock is distributed for storage among a number of reference data memories.
