Abstract:
1. A communication apparatus for dividing an image for one field into groups, the groups including N lines (N≧1), and performing compression/decompression for the groups, comprising: means for separating image data from reception data; means for determining whether an error exists in the separated image data; means for storing the separated image data as interpolation data; means for decoding the separated image data; means for detecting a decoding position of the separated image data and a corresponding position of the stored interpolation data when the means for determining determines that an error exists and that an amount of data missing from the separated image data exceeds a threshold; means for reading the stored interpolation data based on the detected decoding position of the separated image data and the detected corresponding position of the stored interpolation data; means for inserting additional data, wherein: wherein the separated image data is stored as interpolation data when the means for determining determines that no error exists; and means for outputting the read interpolation data, as an alternative to the separated image data, to the means for decoding.
