Description

The invention relates to a digital radio receiver Possibility of recording according to the preamble of claim 1.

Such devices are well known. DE 197 37 322 includes a car radio removable control panels known. This car radio instructs rectangular housing. On the front of the car radio housing is a removable control panel is attached. This control unit is with the Car radio housing connected via at least one contact strip. About these Contact strips are attached to the control panels using the buttons on the Operating commands that can be entered on a control panel in the car radio housing provided microcomputer transferable. The control panel is also with provided an infrared transmitter so that the control panel in the removed Condition serves as a remote control.

DE 197 37 325 describes a communication system for a motor vehicle known. The communication system consists of a plurality of Components positioned at various locations on the motor vehicle are. The components of the system are interconnected via an optical bus connected, for the management of which a microcomputer is provided. Each of the Components has a memory for a system code signal. The Microcomputer is programmed in such a way that it activates a Component checks whether this is in the memory of this component System code signal is stored or not.  

The disadvantage of all these devices is that car radios are usually only for Playback of audio data are provided. Through the newer media, Internet in particular, it is necessary that a car radio in is able to store data, especially music data.

The object of the invention is therefore to provide a digital radio receiver, in particular a digital radio device, in particular for a motor vehicle, show which is capable of audio data, especially music signals, to save, the storage is done by pressing a button and in case an incomplete recording of an audio contribution to one completed later.

This object is achieved on the basis of the features of claim 1.

Advantageous embodiments of the invention result from the dependent Claims and the further description.

The radio receiver for recording audio data consists of a Data GSM module, which is capable of WAP or HTML protocols process, at least one storage medium, a buffer memory, one High speed data interface, a microcomputer and one Broadcast signal receiver, an audio playback unit and amplifier.

For a better clarification of the invention, this will be explained with the aid of a concrete exemplary embodiment with reference to a figure. The figure shows an exemplary schematic structure of a radio device according to the invention. The radio device consists of a central microcomputer unit 1 . A fast data interface 3 and a buffer store 2 are connected to this microcomputer unit 1 . The other component units of the radio are connected via the data interface 3 via a bus, in particular an optical bus. The radio is a digital radio with distributed intelligence. Furthermore, an audio output unit 4 , a fixed memory unit 5 , a GSM module 6 , in particular a GSM data module, as well as a digital broadcast signal receiver 7 and an operating unit 8 are terminated on the bus.

A user can select the various functions of the radio via the control unit 8 . For example, a user can use the control unit 8 to change stations, change the playback volume, etc. If, for example, a music or radio broadcast is currently being played and the user determines that he wants to record this music or radio broadcast, the control unit 8 a button is provided for this. By pressing this button, the program of the selected station is immediately saved. Storage is simple, especially since the data is already being received digitally. The data currently received after the key is pressed is written directly into the fixed memory unit 5 by the microcomuter unit 1 .

At the same time, it is checked on the basis of accompanying data, which is particularly available with digital transmission media such as DAB, whether the contribution is just beginning or is already in the middle of the program. For this purpose, the microcomputer unit 1 instructs the digital broadcast signal receiver 7 to provide the additional information on the contribution. Using the additional information, the microcomputer unit 1 determines whether the contribution is beginning or has already started. If the microcomputer unit 1 determines that the contribution has just started, the microcomputer unit 1 notes this in the fixed storage unit 5 as additional information about the contribution to be stored.

However, if the contribution is not at the beginning but has already started, the microcomputer unit 1 recognizes this on the basis of the evaluation of the accompanying information. In the accompanying information, for example, the current song or contribution is precisely specified. In addition, additional data for the contribution can be transmitted, for example, which gives an indication of the website on which further information on the current contribution can be called up or where the entire contribution can be found on the Internet. If this is the case, the microcomputer unit 1 instructs the GSM module 6 to select that side on the Internet. After selecting the page, the microcomputer unit 1 instructs the GSM module 6 to download the contribution via the Internet and to save it in the permanent storage unit 5 . The post that already exists in parts will be deleted.

The permanent storage unit 5 is configured in the manner. that it can be expanded modularly via additional storage. This is particularly important since the memory can then be freely expanded, for example via multi-media cards. For this purpose, the radio device has interfaces which are accessible to the user and into which he can insert and contact an associated storage medium. The microprocessor unit 1 recognizes a newly added storage medium and logically links it to the fixed storage unit 5 , so that the fixed storage unit 5 is enlarged by the storage of the medium.

Furthermore, a further interface is provided via which data carriers can be adapted, such as multi-media cards, flash memories, DVD data carriers, etc. The data stored in the fixed storage unit 5 can be adapted to the adapted ones by means of the microcomputer unit 1 via this interface Data carriers are transferred. By removing the data carrier after the data has been transferred, the data can be imported into other systems in this way.

Furthermore, data from data carriers can also be imported into the radio via this interface. It is possible to transfer this data into the permanent storage unit 5 or to read it in sequentially and to play it back directly via the audio output unit 4 .

Furthermore, the control unit 8 can be used to set up a separate supplementary database in the fixed memory unit 5 . The microcomputer unit 1 monitors the accompanying information for the radio broadcast via the digital radio signal receiver 7 . If a contribution that is already partially in the memory is now stored in the supplementary database, it is also stored which parts of the contribution are present and which are still missing. If the microcomputer unit 1 now recognizes that a contribution to be completed in the supplementary database which is currently to be received via the digital broadcast signal receiver 7 , it stores the currently incoming data in the buffer store 2 . If the contribution is subsequently in the buffer 2 , the microcomputer unit 1 compares the memory content of the buffer 2 with the associated memory area in the fixed memory unit 5 . It then compares both storage areas and supplements the missing data in the permanent storage unit 5 for the contribution that has already been stored in parts.
