Patent

CA 2325065

A picture coding and decoding apparatus includes a coding section, a demultiplexing section, a coding control section, an error detecting section and a notifying section. The coding section codes a picture data. The demultiplexing section demultiplexes a coded data to output an error detected macroblock number indicative of a number of a macroblock in which an error has occurred and a recovered macroblock number indicative of a number of a macroblock in which the error has been eliminated. The coding control section controls the coding section based on the error detected macroblock number and the recovered macroblock number from the demultiplexing section. The error detecting section detects an error from the demultiplexed coded data. The notifying section notifies another error detected macroblock number indicative of a number of a macroblock in which the error is detected and another recovered macroblock number indicative of the detected error has been eliminated, to another apparatus based on the detection of the coding error.
