Definitions

  • the invention also relates to a device for addressing an image memory, comprising a counter delivering a sequence of 5 binary elements (ebs) in parallel ADR1 to ADR5 to provide the addresses stored, a counter delivering a sequence of 6 ebs in parallel ADC1 to ADC6 to provide the column addresses, and a transcoding circuit which corresponds to a pair of a row address between 0 and 24 and a column address between 0 and 39 a character address between 0 and 999, which is transmitted to the memory in the form of a sequence of 10 ebs in parallel A o to A 9 , characterized in that the transcoding circuit transmits to the image memory the address row ADR1 to ADR5 unchanged when it receives a column address worth at least 40.
  • ebs binary elements
  • the transmission of the addresses stored with a column address of at least 40 provides the read addresses for the positions 1000 to 1023 remaining available in the image memory.
  • the transcoding circuit comprises a transcoding memory to which are applied the ebs ADR1 to ADR5 transmitting the row address and the three ebs ADC4 to ADC6 of high weight, the three ebs ADC1 to ADC3 being transmitted directly at 1 has image memory.
  • a page is formed of 25 rows of 40 characters and therefore includes 1000 characters.
  • the addressing device comprises a row counter 2 capable of delivering 5 binary elements ADR1 to ADR5 in parallel representing the numbers 0 to 31 and a column counter 3 which can deliver 6 binary elements ADC1 to ADC6 representing the numbers 0 to 63.
  • the column counter 3 is incremented by a clock 10 defining the character time interval, equal to 10 image points in the ANTIOPE system, ie approximately 1 ⁇ s, and it is reset at each line synchronization top TLG, ie every 64 ⁇ s.

1. Verfahren zum Adressieren eines Bildspeichers für Teletext-Systeme, der dazu bestimmt ist, die Zeichendaten aufzunehmen, die die Darstellung einer Teletextseite ermöglichen, wobei eine Seite 25 Reihen mit je 40 Zeichen enthält, wovon die erste Reihe eine Kommunikationsreihe ist und der Speicher 1024 freie Positionen besitzt, dadurch gekennzeichnet, daß die 24 Positionen, die nicht den Zeichendaten zugeordnet sind, jeweils den 24 anderen Reihen außer der ersten Reihe zugeordnet werden zum Lesen der Daten, die den Zeichen einer Reihe gemeinsam sind.
2. Vorrichtung zum Adressieren eines Bildspeichers (1) für Teletext-Systeme nach Anspruch 1 mit einem Zähler (2), der eine Folge von 5 binären Elementen (bit) der Reihenadresse 1 bis 6 (ADR 1 bis ADR 5) in parallel abgibt zur Lieferung der Reihenadressen, mit einem Zähler, der eine Folge von 6 binären Elementen (bit) der Kolonnenadresse 1 bis 6 (ADC 1 bis ADC 6) in parallel abgibt zur Lieferung der Kolonnenadressen, und mit einem Transkoder, der eine Reihenadresse zwischen 0 und 24 und eine Kolonnenadresse zwischen 0 und 39 mit einer Zeichenadresse zwischen 0 und 999 verbindet, wobei letztere dem Speicher in Form einer Folge von 10 binären Elementen (bit) Ao bis A9 in parallel übermittelt wird, dadurch gekennzeichnet, daß der Transkoder dem Bildspeicher die Reihenadresse ADR 1 bis ADR 5 unverändert übermittelt, wenn er eine Kolonnenadresse von mindestens 40 empfängt.
3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß der Transkoder einen Transkoder-Speicher (4) enthält, der die binären Elemente (bit) ADR 1 bis ADR 5 zur Übermittlung der Reihenadresse und der drei höherwertigen binären Elemente (bit) ADC 4 bis ADC 6 verwendet, wobei die drei binären Elemente (bit) ADC 1 bis ADC 3 unmittelbar dem Bildspeicher (1) übermittelt werden.
4. Vorrichtung nach Anspruch 3, dadurch gekennzeichnet, daß die drei binären Elemente (bit) ADC 1 bis ADC 3 einem Schalter (5) zugeteilt werden, der gleichfalls die drei geringerwertigen binären Elemente (bit) ADR 1 bis ADR 3 empfängt, wobei der Schalter durch ein Signal (Ac) aus dem Transkoder-Speicher (4) gesteuert wird und der Schalter (5) die binären Elemente (bit) ADC 1 bis ADC 3 übermittelt, wenn die binären Elemente (bit) ADC 4 bis ADC 6 kleiner 39 sind, und die binären Elementen (bit) ADR 1 bis ADR 3 im gegenteiligen Fall übermittelt, wobei dann der Transkoder-Speicher (4) die binären Elemente (bit) ADR 4 und ADR 5 unverändert überträgt.
