Definitions
- the invention relates to a method for data processing in a radio receiver according to the preamble of the independent claim.
- the method according to the invention for data processing in a radio receiver with the features of the independent claim has the advantage that software programs that run on the radio receiver evaluate data in order to control their execution. A user- and / or location-specific and / or time-specific sequence of the programs is thereby achieved, wherein other data locally present in the radio receiver can also be used for sequence control. This leads to a high level of acceptance among users of these radio receivers, and it offers the providers of such programs advantages for the dissemination of these programs.
- the measures listed in the dependent claims enable advantageous developments and improvements of the method for data processing in a radio receiver specified in the independent claim.
- program data and / or data that were generated by means of encoders and / or radio signals received are temporarily stored until they are later evaluated by the programs running on the radio receiver.
- Another advantage is that the data is transmitted using the MOT (Multimedia Object Transfer) protocol. As a result, great freedom in the design of a file size and a quantity of data is used by DAB.
- MOT Multimedia Object Transfer
- FIG. 1 shows a flow chart of the method according to the invention.
- a radio receiver preferably for a motor vehicle, has software that runs on a processor of the radio receiver.
- Such software is one
- the operating system that enables programs running on the operating system to run.
- the operating system also has a software element that creates a device-independent environment for running programs. This makes the programs independent of the respective processor or operating system.
- the software element and also the programs running on it are programmed using the widely used programming language Java, with very small programs in particular, so-called applets, being easy to create here.
- the software element is therefore a Java processor.
- the software element can also run directly on the processor of the radio receiver as a Java operating system. Another way is that the Java processor is integrated directly into the processor.
- the programs running on the radio receiver are received as program data by means of digital radio signals and then put together in the radio receiver so that they can then run as a program.
- DAB is used as the digital broadcasting method.
- DAB is a digital radio transmission method, whereby in addition to the actual audio program, further data information is also transmitted.
- DAB is also particularly suitable for the mobile receiver in a motor vehicle, since the properties of DAB are designed for mobile reception.
- OFDM Orthogonal Frequency Division Multiplex
- error-detecting and correcting codes require that additional data be added to the data to be transmitted in the radio transmitter. Redundancy is therefore added. This redundancy is either added to one end of a data block, or the redundancy is added at different positions between the data using a specified rule. Errors occurring in the radio receiver are then detected and corrected using this redundancy.
- DVB Digital Video Broadcasting
- DRM Digital Radio Mondial
- programs that run using the software element can be stored in a memory of the radio receiver or loaded from other data sources, for example a chip card.
- FIG. 1 shows a flow chart of the method according to the invention, which runs on the processor of the radio receiver.
- method step 1 the DAB broadcast signals are received.
- the received broadcast signals are amplified, converted to a lower intermediate frequency and filtered to eliminate unwanted frequency components.
- the filtered signals are digitized.
- method step 2 the digitized signals are decoded, the error-detecting and correcting codes being used here to correct errors that occur in the digitized signals.
- method step 3 information that is transmitted in individual files within the DAB frame is sorted.
- the respective program is then assembled in step 4 from sorted program data, useful data being treated separately therefrom.
- user data is the data that are displayed by the programs these are texts, images, audio and video sequences, i.e. multimedia data.
- one or more composite programs are started by the radio receiver, and in method step 6, the started programs search for data in order to control their execution.
- This data is either already contained in the digital radio signals, as described above, or the data are taken from local data sources.
- local data sources are donors that are connected to the radio receiver. These are brightness sensors, temperature sensors, an oil level sensor and a gasoline level sensor. These donors provide data that a
- Program compares with the values given in the radio receiver for the respective sensor and informs the user of this change when the value falls below or exceeds this value, this message being displayed on a display device of the radio receiver, so that the user is able to react to this change.
- Another data source is a location device, a GPS (Global Positioning System) receiver that the
- the locating device is a data receiving device here.
- the running program then contains data with which the program compares the current location coordinates in order to arrive at a location-dependent display of advertising or local information.
- the comparison includes a difference between the current coordinates and Coordinates, which are stored in the program as data, and a comparison of the difference with a threshold for the difference stored in the running program, the location-dependent representation for this area being displayed if the difference is below this threshold, and if not, then this location-dependent representation is not represented by the program. If several location-dependent representations for different coordinates are possible, then such a difference is formed with several predetermined coordinates until a difference lies below the predetermined threshold or until all predetermined coordinates have been used to form the difference. In the latter case, the running program does not display any location-dependent information.
- radio receiver as a data receiving device
- other data receiving devices that are connected to the radio receiver are also possible. So is a mobile phone that can also receive data with the
- Broadcast receiver connected and sends data to this broadcast receiver.
- a cell phone can be designed according to the GSM (Global System for Mobile Communication) or the UMTS (Universal Mobile Telecommunication System) standard, but other cell phone standards that are suitable for data reception can also be used. If the radio receiver is stationary, coupling to the telephone network or receiving data via satellite is also possible.
- GSM Global System for Mobile Communication
- UMTS Universal Mobile Telecommunication System
- Broadcast receiver entered.
- the user indicates whether he is interested in certain events, what age he is in order to identify a target group for certain advertising providers, or what other interests he has, for example with regard to bestsellers, music or sports.
- a keyboard, Via which the user makes his entries on the radio receiver is a donor.
- a program that displays news is primarily using this data sports news for the
- the Java processor has interfaces with which the various data sources are addressed.
- the running program accesses these interfaces to load the data from the individual data sources.
- step 7 these data are loaded in order to be evaluated in method step 8 in accordance with the information given above.
- step 9 the execution of the program is then controlled in accordance with the evaluation.
- Data received using DAB broadcast signals are buffered until they are examined by the programs. This ensures that all usable data are used for the sequential control of the programs.
- the MOT protocol allows the addressing of 268 megabytes.
- the data required for the compilation of programs and the multimedia data are transmitted by means of a MOT frame.
