Definitions

  • the invention relates to a radio receiver for reception of radio data, in particular RDS radio receivers, with a receiving part for setting, receiving and Demodulation of a broadcast frequency to be received, a decoder for next to a radio program via a received radio frequency transmitted radio data, a controllable sound influencing device for Control the sound characteristics of a playback Audio signal and a controller that is dependent on a as part of a set at the receiving part Broadcasting frequency transmitted radio data signal transmitted identifier of the sound influencing device assigns predetermined sound characteristics, as well as a Method for influencing a sound characteristic of a audio signal to be reproduced in a radio receiver for Reception of radio data, in particular an RDS radio receiver with a receiver for adjustment, for receiving and for demodulating one to be received Broadcasting frequency, a decoder for next to one Broadcasting program over a received broadcasting frequency transmitted radio data, and a controllable Sound influencing device for controlling the Sound characteristics of an audio signal to be reproduced the genus of independent claims.
  • RDS radio data system
  • a suitable radio receiver essential additional information, such as a program type identifier (Program Type PTY) to identify Art or the content of the currently received Broadcasting frequency transmitted radio program, further a so-called M / S (music / speech) code to indicate whether it yourself within the currently received Broadcast program transmitted signals around music or Voice signals, and finally a TA (traffic Announcement) Code that is played while playing Traffic news within the received Broadcasting program assumes a predetermined value and thus for example, an otherwise one muted radio receiver for the duration of a Traffic announcement enables to transmit.
  • program Type PTY program type identifier
  • M / S music / speech code
  • TA traffic Announcement
  • An inventive radio receiver and that Method according to the invention with the features of independent claims have the advantage that everyone Program type one over a currently received Broadcasting frequency broadcast radio program automatically assigned an optimal sound characteristic so that any type of program, whether pop music, using classical music or speech without user intervention an optimal sound is reproduced.
  • the sound characteristics are related to the present invention on the one hand the frequency response of the audio signal to be played back via a Frequency band-specific amplification of the audio signal can be influenced, for example, by means of an equalizer, on the other hand additional sound effects, such as Understand echo and / or Hall effects.
  • a particularly simple assignment of one for a specific one The type of program intended for the program is included thereby possible that the different for different Program characteristics provided sound characteristics different memory locations within a memory of the radio receiver according to the invention are stored, wherein any storage space for a sound characteristic at least another storage space for storing the associated Program type identifier (s) is assigned. That way by comparing that to that currently on the radio receiver set radio broadcasting frequency Program type identifier with the other storage locations stored program type identifiers a quick assignment a certain sound characteristic to the associated one Program type possible.
  • the following are a radio receiver according to the invention and the method according to the invention using an RDS car radio described, in which according to a first simplest embodiment depending on the Program type identification and, if necessary, further information using the Radio data system of transmitted identifiers, the received one and audio signal to be reproduced has a sound characteristic in Form of a specific frequency response is assigned.
  • the stereo multiplex (MPX) present at the output of the receiving part 20 Signal is also fed to a decoder 30, that from the MPX signal that in the present case by means of Radio data system (RDS) transmitted radio data signal filtered out, decoded and from the radio data signal Program type identifier PTY, the M / S code and the TA code isolated and a controller 15 of the radio receiver feeds.
  • RDS Radio data system
  • the sound influencing device 40 is in the present case in the form of one for influencing the frequency responses of the two stereo channels digital filter.
  • Frequency responses become the sound influencing device 40 or the digital filters on the respective storage space 72 to 78 Filter coefficients supplied by the controller 15.
  • the sound influencing device 40 in the form of an analog equalizer that is the Sound influencing device 40 has a large number of 5 analog bandpasses, for example Center frequencies logarithmic, for example with Values of 50 Hz, 200 Hz, 500 Hz, 3.2 KHz, 12.8 KHz, above the audio frequency band are distributed.
  • amplification factors for analog bandpasses is saved, is a conversion of the Control unit 35 entered strengthening values by the Control 15 not required.
  • FIG. 2 schematically shows a section of an according to the radio data signal 100 transmitted to the radio data system, that according to the RDS specification mentioned in Groups 105 is divided into 106 bits each. Every group in turn comprises four blocks 110, 120, 130 and 140 of 26 bits each, in the RDS specification as blocks A, B, C, D, each block an information part 112, 122, 132, 142 and a so-called check word with superimposed offset word 114, 124, 134, 144.
  • step 200 begins with step 200, for example, by switching on the invention Radio receiver.
  • step 205 the Decoder 30 of the radio receiver according to the invention in addition to the actual radio program on the Receiving part set broadcast radio frequency transmitted Additional information of the radio data signal, in the present If the program type identifier PTY 156, the M / S code 160 and TA code 158 evaluated.
  • step 210 it is checked whether the M / S code a predetermined, a speech signal has characteristic value. If this is not the case, then the flow continues to step 215 where checked whether the TA code is one, a traffic announcement indicating predetermined value.
  • step 230 of the sound influencing device 40 of the radio receiver 10 by means of Control 15 the selected frequency response V1, V2, Vm in the form the stored filter coefficients respectively frequency band-specific gain factors assigned.
  • step 205 that is to say Reading in the PTY, M / S and TA codes again.
  • Embodiment takes place after the start of sequence according to the invention in step 200, for example with switching on the radio receiver, a check 250 whether the automatic program-controlled Frequency response influencing is switched on or not. Is the automatic frequency response control is switched on, see above the sequence according to the invention with steps 205 to 230 or 235 continued according to FIG. 3. Becomes however, determined in step 250 that the automatic PTY code-dependent frequency response influence switched off is, in step 255 a user currently on the Operating device 35, for example by adjusting the assigned to the influenceable frequency bands Sliders, given frequency response and by means of the controller 15 in step 230 Sound influencing device 40 assigned.
