Definitions
- the invention relates to a radio receiver for digital radio broadcasting ( D udio A udio B roadcasting or DAB broadcasts) with loudspeaker outputs, the DAB broadcasts containing different types of announcement, according to the preamble of claim 1.
- Digital radio or " D igital A udio B roadcasting", or DAB for short, is a new form of broadcasting a wireless radio program.
- the radio programs are no longer broadcast as an analog signal modulated onto a carrier signal, as was previously the case on FM, for example, but instead are transmitted in digital form.
- Conventional radio receivers, such as car radios cannot convert this new form of broadcasting into a program audible by a user, rather new receivers adapted to this form of transmission are required, which are subsequently referred to as "DAB receivers" or “radio receivers for DAB broadcasts "are referred to.
- An RDS announcement such as a traffic announcement, interrupts the current program in any case Radio station currently tuned into an RDS radio receiver.
- a user only has the option during for example playing a CD or a music cassette in the background a radio program with RDS announcements from Have RDS receivers monitored and the radio program under Interruption of the current playback of the CD or music cassette to switch to speaker outputs so that the User receives a current traffic announcement. More like that Way, a user can mute the radio program and the RDS radio receiver switches the program automatically on loud when a traffic announcement is identified.
- this previous analog RDS system has the disadvantage that traffic announcements are only available at certain times stand, namely when they are currently being broadcast. In contrast, there are e.g. immediately before driving off with traffic announcements may not be available to a motor vehicle. At this point, however, the first decision is made for a route and a current traffic announcement could be a valuable decision-making aid here.
- DAB announcements not as a program interruption broadcast, but according to the digital character broadcast on parallel data channels and in parallel to the current program. In other words, they are done various announcement types without interrupting the current Program.
- a user wants current and new ones immediately Listen to DAB announcements, so he can perform a corresponding function of the DAB receiver so that recognized DAB announcements immediately audible while interrupting the current program be made. The user can therefore choose whether to be undisturbed listen to a corresponding radio program or current one Receive DAB announcements with corresponding program interruptions would like to.
- This task is performed by a radio receiver for DAB broadcasts the above Kind with those characterized in claim 1 Features resolved.
- an announcement filter is provided, which predefined announcement types under Interruption of a current state of the radio receiver to make the respective announcement audible on the loudspeaker outputs routes and other predetermined announcement types suppressed, so that a current state of the radio receiver is not affected.
- FIGS Claims 2 to 7 Further developments of the device are preferably shown in FIGS Claims 2 to 7 described.
- a single program announcement button (TA +) to control the Announcement filter provided by a first predetermined Activate this either the announcement filter in activated or deactivated in a predetermined manner.
- the first predetermined actuation preferably a short press the program announcement key (TA +), for example from a Second or less.
- An individual selection to pre-determine the desired Announcement types are achieved by the additional program announcement key (TA +) by a second predetermined operation the radio receiver in a configuration mode switches in which a predetermination of those to be let through and announcement types to be suppressed.
- the second predetermined operation prefers one with respect the first predetermined operation, longer operation of the Program announcement key (TA +), for example of more than one Second.
- the announcement types are expediently alarm announcements, Traffic announcements, announcements regarding public Transportation, warnings, news, weather, event notices and / or special announcements.
- the radio receiver is the current state of the radio receiver an audibility of a radio program, one Sound carriers, such as a CD or a cassette, through the speaker outputs or mute the Radio receiver.
- the single figure shows a preferred embodiment of a Radio receiver 100 according to the invention for DAB broadcasts with a receiving part 12 with input filters, not shown, Demodulator, D / A converter and corresponding NF processing. An evaluation is also carried out in the receiving part 12 of the various data channels of the received signal. In a basic setting, the signal of that data channel passed with the radio program as NF in the amplifier 14 and via speaker output 16 and speaker 18 for made a user audible.
- a display device 20 provides the user with various information, such as the currently set reception frequency and similar. Control buttons are on an operating part 22 24 and 26 are provided for operating the receiving part 12.
- An announcement filter 28 continuously checks corresponding data channels the received signal on DAB announcement types, such as "Alarm”, “Traffic announcements”, “News”, “Weather”, “Public Transport”, “Alerts”, “Event information” and / or "special announcement”. Becomes an announcement type is recognized, depending on the control panel mode ignores the announcement or else the receiving part 12 from the announcement filter 28, for example controlled via line 34 such that the DAB announcement forwarded to the NF amplifier 14 instead of the current program becomes.
- DAB announcement types such as "Alarm”, “Traffic announcements”, “News”, “Weather”, “Public Transport”, “Alerts”, “Event information” and / or "special announcement”. Becomes an announcement type is recognized, depending on the control panel mode ignores the announcement or else the receiving part 12 from the announcement filter 28, for example controlled via line 34 such that the DAB announcement forwarded to the NF amplifier 14 instead of the current program becomes.
- the announcement filter 28 can also be integrated into the receiving part 12 or in the signal path between antenna 10 and loudspeaker 18 looped in.
- a first mode the DAB announcements are ignored. In this mode appears informatively in the display device 20 just an indication of which functionalities that Signal of the currently set radio station. Here means e.g. no such display that no DAB announcements get supported.
- An ad "TP” means that DAB traffic announcements are broadcast, but none other types of announcements.
- a display "TP +” means that additionally further traffic announcements are supported and selectively using the announcement filter 28 as desired or are undesirably filterable.
- An ad "P +” means, for example, that traffic announcements are not from Program are supported, but other types of announcement.
- this advertisement can have no or an empty advertisement or alternatively display "TA", “TA + or” A + ", unlike the "TP", “TP +” or “P +” ads above, which only the functionality of the currently set Describe radio stations.
- the first display is blank, i.e. has no ad.
- the meaning of the other displays "TA”, “TA +” and "A +” is described below.
- these two Ads also combined into a single ad be.
- a third mode in addition to the traffic announcements only predetermined DAB announcements on the loudspeaker output 16 given while interrupting the current program.
- This third mode is used in the display device 20, for example displayed with "TA +". So this ad points to one activated support of traffic announcements and at least another type of announcement, but this one Embodiment is not directly named. This type of announcement is set accordingly in the announcement filter is explained in more detail below.
- a fourth mode only predetermined DAB announcements are made to the speaker output 16 while interrupting the current Given the program and traffic announcements are suppressed DAB announcement types.
- This fourth mode is in the display device 20 is displayed, for example, with "A +". This display therefore indicates that support is deactivated of traffic announcements, but at least one more Announcement type is activated. This is set in the announcement filter.
- a program announcement key 24 which is preferably marked with "TA +" can be switched between these modes.
- this Program announcement button 24 is a one-button operation of the Functionality of the announcement filter 28 possible.
- “TA +” can also control the announcement types, i.e. activate, deactivate, interrupt active announcement etc. and in addition a function-related menu with a long one Call up a key press, for example longer than 1 second.
- the announcement filter is preferably also set up to upon detection of a desired, i.e. with attribute Announcement type "ON" mutes the radio receiver to interrupt and the current announcement on to conduct the speaker output 16.
- the announcement filter thus takes on various states. These are only exemplary in the present embodiment labeled “ON”, “OFF” and “PS". “ON” means that the special announcement, if active, is switched through becomes. "PS” extends the filter by adding a Program change only those programs are selected that support the announcement type marked with “PS”. “OFF” indicates that the filter is not active for this type of announcement is, i.e. such announcement types are ignored and not put through.
- a special position takes a supported one Alarm announcement on.
- this announcement is one mobile receiver is always activated, i.e. in the announcement filter marked with "ON” and therefore not in the settings of the announcement filter can be selected manually. Accordingly if it continues to display "empty”, "TA”, “TA +" and "A +" not taken into account.
- RDS R adio D ata S ystem
- broadcast used herein is not limited to the wireless transmission of a radio program, but also includes other transmission paths, such as for example cable transmission or the like.
- the currently selected filter mode of the announcement filter is processed preferred announcement types of the currently on the radio receiver selected radio program. These can be done with the Broadcast signal itself or, for example, on an additional one Channel are transmitted. In a preferred further training the announcement filter also monitors announcement types from other radio stations that are not currently tuned in, which these announcement types on their broadcast signal or a transmit additional channel, and if necessary, places it on speaker outputs, if an announcement type marked with "ON" Will be received.
