Abstract: @ A raster scan display system includes a plurality of storage maps (MAPO to MAP4). These maps are addressable in either of two modes. In the first mode each map contains bit mapped data and the maps are addressed together to provide colour signals from which colour video signals are derived. In the second mode, one map contains character representing data and a further map, character display dot patterns. In this mode the first map is addressed to provide partial addresses for the further map. These partial addresses are combined with row scan data signals to access the further map from which the character display dot data is used to generate the video signals.

Abstract: A facsimile system is so controlled as to reduce four successively scanned source documents and print all four reduced copies on a single copy page. The system prints one of the source documents (44) in each quadrant of the copy document. The images are reduced in the horizontal dimension by discarding every other picture element in the scan image and in the vertical dimension by increasing the speed of the scanner (40) so that the size of the picture element in the vertical dimension is doubled. At the receiver, two scanned and reduced images will be printed on the left-hand half of the copy document (12). Subsequently, two additional scanned and reduced images are printed on the right-hand half of the copy document. When printing the right-hand half of the copy document, the printer is controlled to start printing at the horizontal mid-page of the copy document rather than the left-hand edge of the copy document.

Abstract: A digital display system includes a monitor arranged to receive digital display data and synchronising signals to develop displays on a cathode ray tube. The monitor is switched between different line structure and/or colour definition modes in response to the polarity of one of the vertical or horizontal synchronising signals trains. A circuit receives this train to provide control signals to the horizontal time base and/or a colour signal code converter. The time base control signal, in accordance with its binary value, controls the frequency of the time base. The colour converter, in response to the control signals, either passes colour signals received in parallel over six input lines without change to the cathode ray tube drive circuits or converts colour signals on four of the input lines to output signals on the six lines to the drive circuits.

Abstract: An all points addressable raster scan graphics display system is operable in two modes. In the first mode, data is extracted from a refresh store, serialised, modified, and applied to a display device at a first frequency. In the second mode, data is extracted from the refresh store, serialised and partially modified at said first frequency, but it is then further modified and passed to the display device at an even sub harmonic, for example half, of the first frequency. The further modification includes concatenation of successive groups of display data bits. Accordingly, with the raster scan device operating at a constant scan velocity, the first mode provides a high picture element definition but relatively low colour definition display, and the second mode provides a display with an even submultiple, for example half, the picture element definition but considerably greater colour definition.
