Definitions
- the invention is based on a method for querying Radio text in a radio receiver or from one Radio receiver with a line of the genus independent claims.
- claims have the advantage that radio text, cached after the radio text has been decoded in order to move from a software element in a Operating and display device of the radio receiver to be able to be called up. So that it is the user of the Broadcast recipient allows a message that the Has radio text to view at any time if the user makes appropriate entries using the operating and Presentation device makes.
- the software element is also advantageous in others Components connected to the line included so that it enables these other components will retrieve radio text.
- the software element thus provides represents a universal interface.
- the software element by means of a message on the line that a Receiving device of the radio receiver the radio text has completely decoded and saved. That’s it Software element in the operating and display device informed at any time whether the radio text is available or not.
- radio text requested by the software element completely decoded in the receiving device, then this radio text advantageously immediately to the Software element in the operating and display device sent over the line without prior notice to to make the software element. This will reduce the burden the line reduced, thus the other components of the Information and entertainment system of the motor vehicle Available.
- the invention is improved in that it Software element enables the length of the retrievable Free choice of radio text. That's why it is Software element possible to query only as much radioext as it the display options of the operating and Allow display facility.
- the software element is made possible via the line of the radio receiver to query a new radio text.
- This training allows a user to enter the Communicate software element to determine when the user wants a new radio text so that the Users already have one using the software element stored radio text up to this point can retrieve repeatedly.
- FIG. 1 shows a radio receiver a bus
- Figure 2 shows a method for retrieving radio text
- Figure 3 shows a method for retrieving selectable long Radio text.
- An information and entertainment system in one Motor vehicle with a bus has the advantage of being modular new components can be connected to the bus. So it is possible in addition to the components described above other devices such as a computer to connect. It also simplifies the existence of a bus building an information and Entertainment system, the main component of which Radio receiver with the receiving and operating and Display device is. By means of the receiving device data is received from outside the motor vehicle and by means of the operating and display device, many Components of the information and entertainment system controlled and data, audio or graphics.
- a bus is a line system to which many components are connected connected to a system. It allows a high one Transfer rate, and the data sent over the bus are provided with an address which is intended to what component of the information and Entertainment system to get the data.
- the Bus for example, the CAN bus known in motor vehicles, however other bus standards can also be used.
- Radio text By means of radio text the user becomes one Radio receiver important information such as Weather information, program information and Event information communicated in text.
- FM ultra-short wave
- RDS radio data signal
- DAB Digital Audio Broadcasting
- DAB symbols appear in the DAB signals occur, transmitted in frames.
- a radio receiver is shown, two Components of the radio receiver on a bus are connected.
- a receiving device 1 is connected to a Bus 3 connected.
- an operating and Display device 2 connected to bus 3.
- a line can also be used be, for example, a serial interface is used, with the well-known RS 232 interface can be used.
- Radio signals are received by means of the receiving device 1 received, processed and converted into a data stream, so that they can be operated and Display device will be shipped to there to be reproduced.
- the receiving device 1 means for receiving, processing, decoding and for storing in particular radio text signals.
- a DAB receiver has these funds.
- the receiving device 1 via the bus 3 data sent received and displayed by means of a software element.
- the operating and display device has 2 means for illustration, e.g. one monitor and one Speaker on. If the receiving device 1 is a DAB receiver, then the receiving device 1 is one of the Operating and display device 2 separate unit, which is usually in the trunk of a passenger car is installed.
- the operating and display device 2 controls with which the user of the Radio receiver on address the representation of the Broadcast receiver influenced. This user input will be by means of the operating and display device 2 from the Software element converted into data which, when used for Arrive receiving device 1, the desired by the user Trigger actions.
- the software element has one for the operating and Display device 2 specific programming.
- the size of a display of the radio receiver and how Radio text of a certain length depending on the Size of the ad to be displayed are such specific program parts. For example, that a radio text that is longer than it is on the display can be represented slowly with a given Time is pushed over the display.
- this software element functions to get data over the bus 3 to send and receive.
- the software element is in the general with the English term man-machine interface referred to because the software element in particular the interface between the operating and Representation device 2 and the user controls what so both the user's input and the display of the radio text.
- the user inputs as data are via the bus 3 Receiving device 1 from the software element in the operating and Representation device 2 sent, thereupon corresponding data again via the bus 3 to the operating and Display device 2 sent to the software element.
- This returned data includes, for example, radio text on.
- the user uses control elements assume that he can get the radio text from a memory of the Receiving device 1 on its screen the operating and Representation device 2 would like to see.
- the operating and Display device 2 converts the operator input of the User into signals using the software element the operating and display device 2 in one command can be reformatted via bus 3 to Receiving device 1 sent by means of the software element becomes.
- the receiving device 1 evaluates the command by means of a Signal processing and then sends the radio text via the bus 3 with the information that the radio text from the operating and display device 2 by means of Software element can be displayed on a screen should.
- the software element evaluates this information and sets the radio text on the screen of the operating and Presentation device.
- the radio text is not yet in the receiving device 1 completely decoded, the radio text after the complete decoding automatically to the software element in the operating and display device 2 via the bus 3 sent.
- FIG. 2 shows how an inventive method expires to get radio text.
- Radio text determined from the received radio signals. There are several ways to do this. With RDS a certain signal evaluated to the radio text information to investigate.
- DAB Digital Video Broadcasting
- DRM Digital Radio Mondial
- the determined radio text data decoded.
- this will make a DAB-specific one Segment decoder used.
- the decoding converts the radio text data into a format so that the Radio text data can be further processed and displayed.
- step 9 the software element Operating and display device of the radio receiver announced that new radio text is now being decoded.
- the Decoded radio text is in step 6 cached.
- process step 8 Software element communicated that the radio text is complete was decoded and buffered.
- the software element calls the decoded and cached radio text over the bus in the manner described above.
- this radio text is then called up by the Software element by means of the operating and Representation device shown. This representation takes place, for example, on a liquid crystal screen or a plasma screen.
- FIG. 3 shows a further method for calling up Radio text presented that compared to the process which is shown in Figure 2, the user more Possibilities of influence allowed.
- Method step 10 the user decides whether he would like to have radio text displayed or not.
- Method step 11 is performed by the software element in the Operating and display device checks whether the User would like to have radio text displayed or not. Is if this is not the case, you go back to process step 10 and waits until the user inputs whether he would like to have radio text or not. Has the user input that he wishes to see radio text is up to another input of radio text automatically by the Software element on the display of the operating and Display device 2 brought.
- the received Broadcast signals radio text determined. This happens in the way described above, depending on whether RDS or DAB is used.
- step 5 the radio text is decoded.
- Method step 9 is the software element of Broadcast receiver notified that new radio text is decoding becomes.
- method step 6 the decoded radio text cached. Is the radio text completely decoded? and temporarily stored, the method step 8 Software element a corresponding message for operating and Representation device 2 sent.
- the data is then buffered Radio text retrieved from the software element.
- the difference between the entire radio text and the radio text that has been called up, is cached.
- the old radio text remains in memory and will, if new radio text is required, overwritten.
- the software element can also be used on others Components of the information and entertainment system be installed so that these components Radio text can be called up.
