摘要： The invention provides a fixed length cell handling image communication method wherein moving picture data are compressed to data having a fixed transmission rate using a compression method for still pictures and then converted into fixed length cells so that image processing such as compression/decompression of the moving picture data can be performed at a high rate while keeping a high compression ratio and a high picture quality. A transmission apparatus for use with the method includes an image data compression section for performing still picture compression processing for moving picture data, which define information of a plurality of screens individually divided into a plurality of fields to be successively transmitted per unit time, in response to field timing information representative of a compression timing of each field to convert the moving picture data into variable length data which are independent of each other, a transmission buffer section for converting the variable length data into fixed length data having a fixed transmission rate, and a fixed length cell transmission section for placing the fixed length data and the field timing information into data parts of fixed length cells and transmitting the fixed length cells.
