Definitions

  • the invention relates to a method for evaluating in digital Broadcast broadcasts (DAB broadcasts) contain digitally coded Announcements (DAB announcements) one currently from a DAB radio receiver received DAB station, according to the Preamble of claim 1.
  • DAB broadcasts digital Broadcast broadcasts
  • the invention further relates to a radio receiver for digital radio broadcasts (DAB broadcasts), the DAB broadcasts contain different types of announcements, according to the preamble of claim 12.
  • 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 in any case the current program one in one RDS radio receiver set radio station.
  • a user has only the possibility while playing a CD, for example or a music cassette in the background a radio program with RDS announcements to be monitored by the RDS receiver and the radio program interrupting the current playback of the CD or Music cassette to switch speaker outputs so that the user receives a current traffic announcement.
  • one Mute the radio program and the RDS radio receiver automatically switches the program to loud when a traffic announcement is identified.
  • this previous analog RDS system has the disadvantage that traffic announcements are only available at certain times, namely when they are currently being broadcast. Stand against it e.g. immediately before driving off with a motor vehicle, possibly none Traffic announcements are available. At this point, however, falls the first decision for a route and a current traffic announcement could be a valuable decision-making aid here.
  • DAB announcements different types of announcements, hereinafter also called DAB announcements, not as a program interruption broadcast, but according to the digital nature of the broadcast on parallel data channels and parallel to the running program.
  • the different types of announcements are made without interrupting the current program.
  • a user would like He can hear one of the latest and immediate new DAB announcements Activate the corresponding function of the DAB receiver so that detected DAB announcements interrupting the current program be made audible immediately. The user can therefore choose whether to be undisturbed listen to a corresponding radio program or current DAB announcements received with appropriate program interruptions would like to.
  • EIS 300 401 in addition to the conventional announcement types "Alert”, “Traffic Announcements”, “News” and “Weather”, as already defined in the RDS system, additionally the announcement types "public transportation”, “warnings”, “event information” and "special announcement” defined.
  • DAB announcement types are at least eight other defined announcement types possible, although not yet exhausted. For the User arises the problem that he can either all announcement types hears or none. However, this is unsatisfactory for him because he, for example only interested in traffic announcements, but not for event announcements.
  • DAB announcements contain a header and a message block.
  • the message block contains the actual announcement, while the header information about a geographic Contains location for which the announcement is relevant.
  • DAB transmitting stations further emit a locating signal which is called a TII (T ransmitter I dentification I nformation) and features a geographic location of the corresponding DAB transmitting station.
  • a DAB receiver can extract a geographic coordinate from this TII, which essentially corresponds to the location of the DAB receiver, since this is located in the transmission range of the respective DAB transmission stations or in its radio cell. The smaller the radio cell, the more precisely this geographical coordinate describes the current location of the DAB receiver.
  • a corresponding DAB announcement should also be listened to immediately at the DAB receiver. For this is also made from a geographical transmitted with the DAB announcement Extension and direction information of the DAB announcement relevant event and the second geographical Location at least a third geographic location of an external boundary of the event, followed by a second distance determined between the first and the third geographical location and the DAB announcement immediately to a listener on the DAB radio receiver is heard if the second distance is a predetermined one Falls below value.
  • the DAB announcement is expediently immediately transmitted to a listener is heard on the DAB radio receiver if both the the first and the second distance fall below a predetermined value.
  • the DAB announcement is immediately sent to a listener on the DAB radio receiver is heard if alternatively the first or the second distance fall below a predetermined value.
  • a circular relevant area around the DAB radio receiver is defined in that the listener at the DAB receiver has the predetermined Select value manually.
  • a geographical directivity of the selection of those immediately heard DAB announcements can be achieved by listening to the DAB receiver an environmental characteristic around the DAB receiver selects around which predetermined different ones for different directions Values determined.
  • a directivity of the environmental characteristics in the direction of movement of the DAB radio receiver is achieved by the fact that the environmental characteristics larger in the direction of movement of the DAB radio receiver second values predetermined than in other directions.
  • the environmental characteristics is, for example, oval, rectangular, square or polygonal.
  • the ambient characteristic is expediently chosen such that the DAB receiver is located in the rear third of an extent of the ambient characteristic. As a result, at least two thirds of the messages in question appear as look ahead "or foresighted " .
  • the one with the second distance a different environmental characteristic compared to the predetermined value used as the basis for the one compared to the first distance predetermined value.
  • a radio receiver which a geographical location of a current DAB announcement Event with a predetermined geographic area around the Broadcast receiver compares around, one with the comparator device connected playback device the current DAB announcement audibly reproduces when the comparator device determines that the geographical location of the event within the predetermined geographical Area around the radio receiver.
  • a first evaluation device for a localization signal (TII code) of a currently received DAB transmitter station provided, which from the TII code a momentary geographic location of the radio receiver determined and to the Comparator device there.
  • a second evaluation device intended for a header of a current DAB announcement, which from the header shows the geographic location of the DAB announcement determined event and sent to the comparator passes on.
  • the second evaluation device is designed such that this also consists of a with the header of the DAB announcement transmitted geographic extent of the event together with the geographic location of the event a geographic location an external boundary of the event and sent to the comparator device passes on.
  • the preferred embodiment of a radio receiver 100 comprises a DAB receiver 10 which receives a corresponding DAB radio signal via an antenna 12.
  • the DAB receiver is a contained in the DAB broadcast signal localization signal 14 (TII code, T ransmitter I dentification I nformation) to a first evaluation device 16 for the localization signal (TII code) 14 of a currently received DAB transmission station, wherein the first Evaluation device 16 determines a current geographical location 17 (FIG. 2) of the radio receiver 100 from the TII code 14 and passes it on to a comparator device 18 as a setpoint 20.
  • the DAB receiver 10 also outputs a header 22 of a currently received one DAB announcement to a second evaluation device 24 for the Head block 22 further, the second evaluation device 24 from the Header 22 a geographic location 26 (Fig. 2) of the DAB announcement determined event and sent to the comparator 18 passes on as actual value 27. Possibly. determines the second evaluation device 24 further from a direction and an extension 28 (FIG. 2) of the event a geographic location 30 (FIG. 2) of an outer boundary of the event and also gives this location 30 to the comparator device 18 further. For example, the location as well as direction and extent 28 of an event according to specification ENV 12313 (RDS-TMC coding) and transmitted using a table or similar. the geographical Places 26 and 30 implemented.
  • ENV 12313 RDS-TMC coding
  • the DAB receiver 10 also issues a message block 32 of the DAB announcement, which contains the actual announcement information to a Output control 34 further, which with the comparator 18 connected is.
  • the comparator device 18 controls 36 depending on the result a comparison of the geographical location 17 of the radio receiver 100 with the geographical location 26 of the event or the geographical Place 30 of an external limitation of the event's output control 34 so that this is the currently received DAB announcement optionally listen to a listener immediately via issue 37 brings or saves for later retrieval. For example, if Distance between the geographical location 17 of the radio receiver and the geographic location 26 of the event and / or the geographic Location 30 of an outer boundary of the event is less than one predetermined value, then the currently received DAB announcement immediately brought to the listener's ear. This will be explained later using a concrete example according to FIG. 2 explained in more detail.
  • the user gives a radius or distance 38 via an input device and direction of what is referred to below as the environmental characteristic geographical area 40 (FIG. 2) around the geographical Location 17 (FIG. 2) of the radio receiver 100 around, which is a requirement 42 is passed on to the comparator device 20.
  • the environmental characteristic geographical area 40 (FIG. 2) around the geographical Location 17 (FIG. 2) of the radio receiver 100 around, which is a requirement 42 is passed on to the comparator device 20.
  • FIG. 2 schematically shows a reception situation for a device according to the invention Radio receiver at the current geographical location 17, which, for example, in a motor vehicle from A-Dorf 44 on a Traffic route 46 moved in the direction of B-City 48.
  • Radio receiver at the current geographical location 17, which, for example, in a motor vehicle from A-Dorf 44 on a Traffic route 46 moved in the direction of B-City 48.
  • an environmental characteristic 40 has a listener, who in this case is a motorist, a circular ambient characteristic 40 with a radius 50 ⁇ m selected the current location 17 of the radio receiver around.
  • the radio receiver now receives a DAB announcement, which is a
  • the traffic route 46 is completely blocked shortly before the B-City 48 with a backwater 28 in the direction of A-Dorf 44.
  • the evaluation of the TII code 14 by the first evaluation device 16 gives the current geographical Location 17 of the radio receiver (for example 20.00 North and 8.25 west).
  • the evaluation of the head block by the second evaluation device 24 gives the geographic location 26 of the full closure (e.g. 9.96 north and 8.12 west).
  • the comparator device 18 notes that the distance between locations 17 and 26 is greater than that Radius 50 of the environmental characteristic 50 is. In other words the full lock 26 is not within the ambient characteristic 40. Therefore the DAB announcement would not be played immediately but for one saved later.
  • the second evaluation device 24 additionally determines from the Direction and extent information 28 the geographic location 30 the end of the traffic jam in the direction of A-Dorf 44 (e.g. 9.00 North and 8.16 West). For this purpose, the comparator device 18 determines that the Congestion end 30 within the user-specified environmental characteristic 40 is located and controls the output controller 34 in such a way that the driver receives the currently received DAB announcement immediately brings to hear. This can be done using this immediately received information on the traffic situation with a corresponding route selection via, for example react immediately to an alternative road.
