DEVICE FOR RECEIVING AND PRESENTATION OF WEATHER FORECASTS AND WEATHER DATA

摘要

A device for receiving and displaying weather forecasts and weather data which can be used by weather-dependent community throughout the country. The device utilizes a channel transmitting together with the ordinary broad casting programs and containing coded weather information from a transmitter in the form of a data groups (G). Each group contains a forecast head (PH) and associated fore casts data sections (PD) indicating the weather information. The device contains a signal receiving unit (1, 4, 5, 6) which recovers data signals representing the groups (G), as well as a signal processing unit (7, 8, 9, 10, 11) and a display unit (15). The signal processing unit contains a decoding unit (7) for decoding the signals recovered from the signal processing unit and for indentifying the weather information in the groups. Moreover, there is a forecast memory (9) storing forecast data (PD) on addresses determined out of the forecast head (PH) as well as a control unit (11) controlling the read out of the forecast memory and storing forecast (PD, PD2, ...) associated with one or more groups (G). The weather symbols can be stored in a special symbol memory (10) or in the display unit (15) which is controlled by the control unit for display of the weather forecast.
