Abstract

PURPOSE:To reduce load on a software, by accumualting each information medium as a code, a dot data, and a geometric command data, and processing them independently corresponding to each information medium by the combination of those media and a managing table and a dedicated hardware. CONSTITUTION:A bit of information from another communication terminal equipment is accumulated in a memory device 4 at every medium. Also, in a memory device 2, the addresses representing start and completion by every medium, and the data for the display start position of a part to be displayed on a screen and the priority of the display of a block to which the data belongs are accumulated. The data accumulated in the memory device 2 is read out at a display address generating part 3 by an arithmetic unit CPU1'. The data corresponding to the signal is read out by the signal, and is converted to the data of dot code at every medium at an information medium conversion part 5. The data is transmitted to a registration control part 6, and the data to be displayed on the screen is outputted in a sequence of priority order. Therefore, the CPU performs only the generation of a conversion table based on the content of the managing table.

In FIG. 1, information from other communication terminal devices is stored in the storage device 4 for each medium, and the storage device 2 also stores the start and end addresses for each medium and the display portion on the screen. Data regarding the starting position and the display priority of the block containing the data is accumulated.

The data stored in the storage device 2 by the arithmetic device 1 is read out by the display address generation section 3, and the data is converted into a signal for reading the data stored in the storage device 4.

In response to this signal, the storage device 4 reads the data at the address corresponding to the signal, and the information media converter 5 converts it into dot code data for each medium. This data is sent to the superposition control unit 6, and the data to be displayed on the screen is determined based on the data sent from other blocks and the data indicating the display priority of the block from the display address generation unit 3. Output in order.
