Definitions

  • the invention relates to a method and a device for the mobile receiving of programs with a receiving unit according to the features of the respective preamble of the independent claims.
  • a receiving unit consists of at least one receiving train, comprising an antenna, a receiver and a playback device.
  • the invention is therefore based on the object of specifying a method and a device for the mobile receiving of programs with a receiving unit, with which the receivable programs that are emitted within a transmission area of a transmitter, faster in a program list displayable and thus reproducible.
  • the received programs are assigned to a transmission area and the respective programs assigned to a transmission area are stored in a reception area profile, in which case If, when receiving programs, a stored reception area profile is recognized, the reception unit is set to this stored reception area profile.
  • the receiving unit the receiver
  • an additional receive path can be avoided with which otherwise a station search would have to be performed in the background. Due to the transmitter landscape existing today, for example in Germany, it is easily possible to delimit individual transmission areas from one another.
  • a transmission area can also be defined independently of the program, for example by using the navigation system of a vehicle to regionally define transmission areas. This can be done taking into account the stations in that area or independently.
  • the channels on which the respective programs are broadcast are stored in a reception area profile, a program search being carried out upon detection of a respective transmission area and newly recognized programs being stored in this reception area profile.
  • This process step lends itself to diversity systems, since there are generally several reception trains available, wherein at least one of the reception trains is used for receiving and displaying the program, while a further station is used to perform a program search to either re-allocate a reception area profile or to update an already created (saved) reception area profile.
  • the receiving unit is set to this reception area profile.
  • this profile is displayed and the receiving unit is set to this profile, so that a complex search can be omitted and all programs which can be received in this assigned broadcasting area are displayed and selected can be.
  • At least one received program is contained in more than one reception area profile
  • at least one further received program for selecting the reception area profile is used in accordance with the invention.
  • an apparatus for carrying out the method described above has at least one receiving unit, a signal processing unit (hereinafter referred to as host) and a memory.
  • Figure 1 shows the essential parts of the apparatus for performing the method, namely the receiving unit (with one or more receiving trains, consisting of at least one antenna, a receiver, optionally further signal processing means and a playback unit), the signal processing unit and the memory.
  • the receiving unit is required to receive the (digital and / or analog) programs or channels and to filter out various information from the found and receivable programs. This information must be provided by the receiving unit to the host.
  • the host evaluates the information received from the receiving unit and decides how to continue the search strategy (see claims 2 to 5).
  • the information evaluated by the host is stored in the memory of the receiving unit. At a predeterminable time, the host and / or the receiving unit may use the stored information for the first time or again and if necessary use it for an adaptive search strategy.
  • the receiving unit evaluates the information sent to a program or channel and makes it available to the host. This then stores in a database in the memory the information provided by the host. If the transmitter landscape (that is to say the programs and channels stored for a broadcasting area) does not change for a specific time, then all the information of the channels and programs found is combined into a block (so-called reception area profile). This means that for a certain time the receivable stations are received and their data is stored in the memory. After the predetermined time has elapsed, the storage of a first reception area profile takes place and a new reception area profile is then filled with data and stored. Beside this Time parameter, however, it is also conceivable, as described above, to use other parameters for generating a receiving area profile.
  • the database in the memory fills with the program and channel information of the programs and channels found, all of which are combined into reception area profiles.
  • FIG. 2 shows by way of example three reception area profiles stored in the database of the memory.
  • the first reception area profile contains information about the reception area 1, that is to say information on programs and channels which are radiated in the first transmission area by the transmitters located there. These are, for example, program A (receivable on channel 23), program B (receivable on channel 56) and program C (receivable on channel 66).
  • This information has already been received and stored by the at least one receiving train of the receiving unit. It is assumed that this is the broadcasting area Berlin.
  • the channels (11, 23, 45) of the programs A, B, D have been stored, which can be received, for example, in the transmission area Hamburg.
  • the host who has received this information from the reception unit can select the reception area profile 3 and set the reception unit to the programs B, C and D stored there , This means that no further search is required for the other programs B and D so that the list of receivable programs can be made available to the user much more quickly. If the user leaves the broadcasting area of Kunststoff and moves into the Hamburg broadcasting area, the previously described process performed again so that then within a very short time the list with the receivable programs and channels of the second Empfangs involvedsprofiles can be displayed and selected and played back.
  • FIG. 3 shows the interaction of receiving unit, host and memory.
  • the receiving unit indicates to the host that channel D has been found on channel 45.
  • the host forwards this request to the memory, whereby it is recognized that program D is contained on channel 45 in the second reception area profile (here in the example Hamburg).
  • This result causes the host to select the reception area profile 2 and set the reception unit to the channels 11, 23 and 45, with which the programs A, B and D can then be received, displayed in a program list and played back according to selection.
  • program is understood to mean in particular analogue or digital radio broadcasting or television programs, but other services are not excluded.
