Abstract

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.
