Data distribution device and method

摘要

On a data terminal compatible only with a specific image data format, image data in an incompatible data format could not be viewed. In addition, on a small display screen, only small-size image data could be viewed. In response to an image data distribution request from a data terminal (130), a data distribution device (100) converts the format of image data incompatible with the data terminal (130) before transmission to the data terminal (130). In addition, the data distribution device (100) adds image operation buttons in order to send enlarged image data corresponding to any of the buttons.
