VIDEOTEX SYSTEM WITH PUBLIC TERMINALS |
摘要 |
In public videotex (Btx) terminals, different pages are displayed successively on the screen in the off-line mode (e.g., advertisements and user instructions). To be able to update such off-line pages at low cost, a page memory in the terminal is constructed as a random-access memory (46). A central operating facility contains an editing device in which the information and control characters required to display an off-line page are produced. These characters are transmitted to the terminal and written into the random-access memory (46). This may be effected automatically when the supply voltage is turned on. |
