摘要
The invention relates to a method and apparatus for the simultaneous text display of theatre, opera and the like performances or information regarding events or exhibitions. The invention comprises the use of image producing units (3) distributed among the audience, which are provided with a display unit (5), to which a text is transmissible from the image producing unit (3) by means of an electrical signal. The display unit (5) is provided with optics for converting the image to an enlarged and distanced virtual image. The text is stored in one or more languages either in a computer (1) controlling the timing of a display or in said image producing units (3) to be distributed among the audience. Text portions, or control commands for timing the display thereof, are transmitted via a radio link to the image producing units (3), by means of which a text presentation language is selected.
