METHOD AND DEVICE FOR TRANSMITTING TELETEXT PAGES |
摘要 |
In interactive teletext, an individual user establishes a connection (6) with a central computer (14). Requested information is applied to a television transmitter (12) via a teltext inserter (11) and transmitted to the user as personal teletext pages for display on the user's receiver (3). However, other users (4) may be "co-viewers". In accordance with the invention, each personal page is transmitted with a teletext page number P and a sub-code S. Subsequently, a pseudo-page having the same page number P but a different sub-code S' is transmitted. Consequently, the personal page appears on the display screen of the co-viewer's receiver (4) only for a short time. |
