Definitions

  • the invention relates to a method for receiving high-frequency signals, wherein a program to be reproduced by means of a first reception train is received by means of a first standard and by means of at least one further Empfangs Komes in the background for the same program to be reproduced that can be received on at least one standard, wherein the program to be displayed is displayed in a program list and can be selected, according to the features of the preamble of claim 1.
  • a television program to be reproduced can be selected at the receiving equipment.
  • the receiving device receives those high-frequency signals of the standard with which this selected program can be received just at the location of the vehicle. If this standard has been agreed, the desired program can be reproduced in the vehicle.
  • This program to be displayed is then displayed in a program list. Meanwhile, you can search in the background for further programs with another reception train, which can be received just at the location of the vehicle in addition to the program to be played. These programs are also displayed in the program list. The operator now has the option of selecting the program he wants to see from the illustrated Prague ram list.
  • this known method and its receiving device is only suitable and designed to perform the switching from one program to the other program within the same standard. That is, the receiving device is designed only to receive, for example, the program ZDF, which is emitted by a first transmitter analog / digital. If the vehicle changes to an area in which this program is no longer broadcast by the station on the same standard, the program ZDF can receive the same standard, but not on a different standard
  • a standard is characterized by having different reception parameters such as modulation, coding, codecs used for audio and video.
  • reception parameters such as modulation, coding, codecs used for audio and video.
  • a separate receiving hardware is usually required, which together results in a receive path. This means that each receive path (foreground, background) has separate hardware for each standard.
  • the different receiving hardware is then assembled into a receive path.
  • service flowing refers to a method which gives the user the option of following the selected service, even across different locations.
  • service is understood to mean a program (eg ARD, ZDF etc. in Germany, CCTV1, NHK etc. in China, Japan and the like).
  • the TV receiver automatically changes the reception frequency and thus tries to always offer the user the best quality of the set program.
  • This method is known from DE 10 2005 039 507 A1 and is implemented in many mobile-compatible receivers. However, this method is disadvantageously limited to a single standard.
  • the invention has for its object to provide a method for receiving high-frequency signals for mobile television reception, which is improved over the prior art.
  • the programs receivable by means of the at least one further receive train are displayed in an alternative list as alternatives to the program to be displayed, wherein, if an alternative of the program that can be received on the at least one further standard is selected first receive train is tuned to this further standard.
  • the method according to the invention and the correspondingly configured receiving device it is thus possible to first display in the program list at the respective location of the vehicle that program which was selected by the operator whom he wishes to watch.
  • the first reception train that is to say its means for receiving, processing and displaying the signals, is tuned to this program so that it can be displayed.
  • the station tracking is used across all standards.
  • the TV receiver ie the entire hardware of each Empfangs Komes
  • Transmitter tracking over multiple standards can only be performed if the TV receiver has at least two receive paths. These two paths are usually called the foreground path and the background path.
  • the foreground path displays the currently selected program (service).
  • the program list is permanently kept up to date. This method is designed for mobile use, since the reception situation of the programs is constantly changing.
  • an alternative list is stored for each receivable program, this alternative list containing the information about all parallel available programs that can be received by means of the same or a different standard, which broadcast the same content.
  • the alternative list of each program is permanently updated via the second reception train. This has the advantage that at any time alternatives to the program being played back are available for selection.
  • each program (service) has an alternative list. This list contains the information about all parallel available programs that broadcast the same content.
  • the alternative lists are also permanently updated via the background path.
  • a check is made in the currently available program list as to whether a program with the same content is already present and then, if in the program list Program with the same content already exists, the newly found program is entered in the alternative list of the associated program list of the currently playing program.
  • a new service is found via the background search (background path)
  • it is checked in the currently available program list whether a program with the same content already exists. If a program with the same content is found in the program list, the newly found service is entered in the alternative list of the program.
  • the currently received program is permanently monitored and switched on the basis of predetermined criteria of the program to be played, which is received on the one standard to the same program that is received on a different standard, if the predetermined parameters predeterminable thresholds exceed.
  • the monitoring of the alternative services must also be carried out cyclically in the background. The same parameters are available as for monitoring the current service. Again, thresholds are set that must be exceeded in order to use the service as a real alternative.
  • FIG. 1 shows a program list visible to the user. This consists in the example of four programs, with the program 2 is selected as a program to be played.
  • FIG. 2 shows the same program list as in FIG. 1, it being further recognizable that at least one program in the program list, preferably for each Program from the program list an alternative list is generated and exists.
  • the program 2 to be played which is currently being received with a standard
  • Figure 3 shows the same situation as in Figure 2, but it is shown that in the alternative list the first program 2 on channel A with the standard I the same program 2 alternatively on the channel B with the standard II and also the same program 2 Channel C can be received with the standard III. This means that both the program 2 listed in the program list and currently being played and the programs 2 listed in the alternative list can all be received on different standards.
  • Figure 4 shows the same situation as in Figures 2 and 3, with the following difference.
  • the background search determines that the program 2 can not only be received and reproduced with the standard with which it is currently playing (in the program list) and not only on the channels A, B and C in FIG the standards I, II and III is radiated, but with the same content also on channel D by means of the standard I or II or III or another standard IV can be received. If this is found out, this newly determined program 2 is entered in the alternative list. This is shown in FIG.
  • FIGS. 5 and 6 show that program 2 is received in the program list by means of a standard which is not described in more detail and is currently being reproduced.
  • the variant is that the program 2 is received in the program list on channel A and played back.
  • the program in the program list also appears in the alternative list and is displayed. This may or may not be the case.
  • the program 2 in the program list is recorded and reproduced by this program 2 on channel C. , This is shown in FIG.
  • the one program which was shown in the alternative list and which is to be played back be included in the program list and then disappear from the alternative list.
