  • Annotazioni

  • The Labgear Teletext adaptor, unlike receivers with built-in Ceefax and Oracle decoders, is an external "add-on" unit that may be fitted between the aerial and a standard 625-line colour (PAL) or black-and-white television receiver. Normal picture facilities are retained with the adaptor in the circuit. This unit, type CM7026, can provide colour displays for all normal teletext facilities and may be used in specialised applications where pages of interest are required "piped" simultaneously to several receivers located throughout a building from a single adaptor, for example as in stock exchanges, bookmakers or education establishments.

    The adaptor, which makes use of TIFAX l.s.i. decoder circuits from Texas Instruments.

    TIFAX is a microprocessor-based module. This module decodes Teletext signals, which are sent during the field-blanking interval of TV transmissions, and displays the data in alphanumeric form on the screen of a TV set
