Abstract
1404066 CRT character displays HOLLANDSE SIGNAALAPPARATEN BV 17 July 1972 [23 July 1971] 33411/72 Heading H4T An arrangement for display of alphanumeric data on a television monitor comprises a number of recirculating buffer stores, one for each row of characters, which are successively connected each for a number of scan lines to a video signal generator, and addressing means for modifying characters at desired points of the display. As shown each row of characters is stored in a recirculating memory 4a, 4b &c (32 rows may constitute a complete display) each of which consists of six loops for 6-bit parallel representation of the character codes. A timing circuit 38 provides signals to pass the contents of these memories in turn to a video symbol generator, data from each so passing 18 times (for a 7 x 10 matrix display with 8 line spacing between rows of characters), and the symbol generator receiving also line count signals. Entry of a new character is enabled by circuit 5 which receives at 12, 13, 16 the character code, row designation and column position respectively, and at the appropriate column count in 17 comparator 18 supplies a signal to enable circuit 14 to produce a row signal which disables the recirculation (gates 31-36) and enters the data from 12. In a modification (Fig. 4, not shown), the recirculating memories 4a &c. are each constituted by a single loop with the six bits of a character entered serially, and read-out from a memory is via a series-parallel converter into a parallel memory of the Fig. 2, type.
