A guide of a broadcasting program with a computer software product, in which a transmission start time, a name of the broadcasting program, a name of the computer software product, a version number of the computer software product and a terminal type required of a terminal are listed, is transmitted from a center station to each terminal. Also, files of the computer software product are transmitted from the center station to each terminal with video-audio data of the broadcasting program at the transmission start time. In each terminal, a particular terminal type of the terminal and a particular version number of the computer software product downloaded in the terminal are managed. In cases where the particular terminal type of the terminal agrees with the terminal type listed in the guide and the particular version number of the computer software product is higher than the version number listed in the guide, the downloading of the computer software product is judged, and the computer software product is downloaded to the terminal at the transmission start time. Accordingly, the computer software product can be downloaded to user's terminal without requiring a special frequency band used only for the computer software product. Also, because the computer software product received in the terminal is updated, the user can always execute the updated computer software product.

A remote operation apparatus comprises a MA term having a video display, an operation data generator, and a parameter data generator and at least a slave term, coupled to the MA term through at least a network, including operation data receiver, a video data generator and a display, a screen parameter receiver, and a video data acquiring portion. The operation data generator generates and transmits operation data to the video data generator of the slave term to generate and display video data. The screen parameter data generator generates screen parameter data indicating required video data and quality and transmits it to a video data acquiring portion acquiring the generated video data in the required region and quality and transmits it to the display of the MA term. A resource data of the networks and interface ckts is held by the slave term and is transmitted to the screen parameter data generator to utilize the resource data for generation of the screen parameter. The operation data generator may require to transmit drawing data to the slave term. The MA term holds imaginary screen including screen regions of slave terms. The operation data can be duplicated for another slave term. The video data in one slave term is duplicated in the memory in the MA term and transmitted to another slave term.

A three-dimensional data shaping apparatus defines a working region, as a region of specific size and shape within a reference three-dimensional space, with a corresponding display picture being generated. A user can move the working region, using an input device such as a mouse, to select a specific part of a work object that is represented by a set of constituent data elements within the reference space, and execute shaping of the selected part. Determination of a selected part is performed in two judgement stages, i.e. a first stage in which a judgement is made as to interference between the working region and a number of fixed-size small regions into which the three-dimensional space is considered to be divided, and a second stage in which a judgement is made as to interference between the working region and only those constituent elements of the work object which correspond, according to predetermined criteria, with those of the small spaces for which interference has been found in the first judgement stage.
