摘要：
A terminal apparatus is provided for displaying an image by reproducing a piece of image information and for interactively changing the image using navigation information. The image is a moving picture, a still picture, or a mixture of them. The image information and the navigation information together are broadcast by a broadcasting station to the terminal apparatus. The navigation information indicates a plurality pieces of link-target image information. The cache unit stores a pair of image information and navigation information. The reproducing unit reproduces the image information. The monitoring unit monitors whether an operator has performed a certain operation responding to the image displayed. The receiving unit, before the operator performs the certain operation, receives a plurality pieces of image information which have possibility of being displayed and a plurality pieces of corresponding navigation information based on the navigation information, and stores the plurality pieces of image information and navigation information in the cache unit. The specifying unit specifies a piece of link-target image information based on the certain operation. The identifying unit identifies the piece of link-target image information as a piece of image information.
