REMOTE EDITION SYSTEM, MAIN EDITION DEVICE, REMOTE EDITION DEVICE, EDITION METHOD, AND RECORDING MEDIUM

摘要

To hierarchically encode image data for compression purposes to ensure that a detailed remote editing operation can be performed with high efficiency by making the most of hierarchical encoding. A main editing machine (Fig. 2) transmits hierarchically encoded data for image formation to a remote editing machine in accordance with an employed network band and a remote editing machine's capacity. At the remote editing machine, an editor performs edits by using the hierarchically encoded data. Editing information, which is created as a result of editing, is transmitted from the remote editing machine to the main editing machine. The main editing machine transmits difference-representing hierarchically encoded data to the remote editing machine in accordance with the editing information. The remote editing machine generates edited image data by using previously received hierarchically encoded data and the difference-representing hierarchically encoded data transmitted from the main editing machine. Thanks to hierarchical encoding, the hierarchically encoded data can be minutely hierarchized for elements defining picture quality such as resolution and image quality.
