Definitions

• the invention relates to a device for receiving and displaying additional program-accompanying information in radio broadcasting.
• the invention has for its object to provide a device for receiving and displaying additional, program-related information in radio broadcasting in such a way that the relevant data and texts can be better displayed and optimally evaluated and exploited by the radio subscriber.
• an interface is advantageously provided which allows the connection of Text-representing and / or text or data processing peripheral devices allowed. This makes it possible to tap the additional information received from the decoder at a suitable point and to forward it to corresponding peripheral devices for display or further processing.
• home computers which are already widespread in today's households, offer many options for automatically and yet individually evaluating additional information of the type considered here, i.e. radio text or alternative radio program information.
• the combination of a home computer with the device according to the invention allows, for example, an individually definable and automatically executable program compilation.
• certain messages that are not only of momentary importance for example sports results, event information, etc., can be stored on the home computer and can then be accessed again at a given time.
• a bidirectional, expediently serial data interface is particularly suitable as an interface, which requires little technical outlay and nevertheless permits sufficiently fast data transport in both directions.
• the interface For the coherent and clear presentation of additional information received, it is also advantageous to design the interface as an interface for the decoupling of a video signal. For this purpose, it is necessary to store all the characters or symbols to be displayed as a pattern in a memory assigned to a character generator. The single ones Characters or symbols are retrieved by the codes transmitted as additional information and fed to the interface as character video signals via a playback control. This gives you the option of connecting a large, external display or monitor. In a particularly advantageous manner, an already existing television receiver can also be used as a viewing device.
• the interface can also be supplied with control and information signals, which allow the control of a printer, via a corresponding reproduction control assigned to the memory and the character generator.
• a particularly advantageous and inexpensive embodiment of the device according to the invention results if the interface is designed as a unidirectional, teletext compatible interface, via which the character generator arranged in a television receiver with a teletext decoder can be controlled. In this case, a separate character generator and additional storage devices can be omitted. If necessary, only a transcoder is to be provided, which converts the codes transmitted as additional signals in radio broadcasting into codes which correspond to the character codes of the teletext.
• the possibility of connecting a large-area display, a monitor or an existing television receiver also allows the program-accompanying information, in particular transmitter and program-related data, in the form of Display menu tables or program tables, which results in a simple type of user guidance. This makes it easy to enter and perform difficult searches, for example, by station name or program type.
• a chronologically ordered listing of program contributions on the screen also offers the user the opportunity to select various programs of interest for magnetic recording, for example with the aid of a cursor, and to check for their temporal collision.
• the device according to the invention does not have to form a structural unit with a radio receiver. It can also be structurally separated from a radio receiver and connected to it via a corresponding connection socket to which the demodulated IF signal, possibly cut in the frequency response, is present. This is advantageous if the radio itself cannot process any additional information or only to a limited extent.
