Definitions

  • the invention relates to a mobile radio receiver.
  • the invention further relates to a method for receiving a radio channel.
  • the invention further relates to means for determining the position for use in a mobile radio receiver.
  • Radio receivers are known in the art. Radio receivers are usually equipped with a number of preset possibilities to store the relevant transmitters. When these presets are used in a FM-mobile radio receiver (portable, car etc.) the user is confronted with the phenomenon that FM-transmitters only have a very limited coverage. With modern techniques like R(B)DS and fast responding tuners a kind of following system may be implemented. For slow responding tuners there is currently no switch option available.
  • EP-A-0 462 116 From the European patent application EP-A-0 462 116 a method and a radio receiver using RDS is known.
  • a first aspect of the invention provides a mobile radio receiver as defined in claim 1.
  • a second aspect of the invention provides a method for receiving a radio channel as defined in claim 6.
  • An advantage of a mobile radio receiver comprising means for determining the position of the receiver is that the mobile radio receiver can use this information by selecting the strongest FM-transmitter, for example.
  • the performance of the radio receiver is improved considerably because now the radio receiver can switch over before the FM-transmitter is weakening whereas with the normal RDS system the radio receiver is switching over when it is detected that another FM- transmitter is received stronger than the present one.
  • An embodiment of a mobile radio receiver according to the invention comprising the features as defined in claim 2.
  • a further embodiment of a mobile radio receiver comprises the features as defined in claim 3.
  • a radio receiver comprises cellular (for example GSM) or GPS equipment it is possible to use the information from the cellular or GPS equipment when choosing the strongest FM-transmitter.
  • GSM Global System for Mobile Communications
  • GPS equipment By using this information in an array-like structure in the radio receiver preset system, the user can create his own follow system based on so-called position awareness. Combining this information also with the R(B)DS information even further enhances the possibilities not only for slow tuning systems but also may improve the R(B)DS follow behaviour for fast tuning systems.
  • the invention concerned can also be used for the so- called DARC-system as used for data in for example Japan and USA.
  • Figure 1 a block-schematic example of a mobile radio receiver according to the invention
  • Figure 2 examples of a preset list.
  • Figure 1 shows a block-schematic example of a mobile radio receiver according to the invention.
  • the mobile radio receiver will in this example be equipped with a matrix of preset arrays, where the extra one side of the matrix is loaded with (provision) information.
  • this position information may come from the transmitted cell information (e.g. REGIO040).
  • REGIO040 the transmitted cell information
  • this position information may be generated by the receiver itself through a learning system based on GPS co-ordinates. Through this learning system the receiver creates its own cells.
  • a manual control will be described and later on an automatic control will be described.
  • the user manually stores his favourite stations under the various preset keys.
  • a second parameter is the position information, which may be used automatically or manually (REGION XX).
  • the radio receiver may use this information by automatically switching over between corresponding presets when the position information changes.
  • Figure 2a shows an example of a manual control whereby an array of preset numbers 1, 2.... is filled in, whereby for each region (REGION 1, REGION 2, etc.) the different FM transmitter frequencies are filled in.
  • the radio receiver will automatically switch from 88.2 to 92.6 (if the user was listening to preset 1).
  • FIG 2 shows an example of an automatic control whereby the PI (program information) code information from the R(B)DS system is added to the information flow, it is no longer necessary to use a uniform sequence.
  • the Pi-code information is also stored in the preset array (together with the frequency information). By checking not only the position information but also the Pi-code information the radio receiver can directly switch over to the corresponding station.
  • the Pi-code information is shown in Figure 2b between brackets as for example (8202), (8203).
  • the radio receiver will automatically switch from 88.2 to 92.6 (if the user was listening to preset 1 in REGION
  • the performance of the radio receiver is improved considerably because now the radio receiver can switch over before the FM-transmitter is weakening whereas with the normal RDS system the radio receiver is switching over when it is detected that another FM- transmitter is received stronger than the present one.
  • the invention concerned can also be used for the so-called DARC-system as used for data in for example Japan and USA.

Abstract

Les radiorécepteurs mobiles d'aujourd'hui bénéficient des techniques R(B)DS qui permettent d'écouter une station, en voyageant, sur la plage de couverture d'un émetteur F.M. Afin d'améliorer ce radiorécepteur mobile, la présente invention concerne un radiorécepteur mobile qui utilise des moyens permettant de déterminer la position géographique de ce récepteur.
