Definitions

  • the invention relates to a method and an apparatus for recording and / or reproducing data.
  • a car radio which is connected to a large capacity memory (e.g. a few gigabytes). Audio data, in particular music data, are stored in this memory. In one embodiment, the audio data are stored in compressed form, so that a very large number of data, in particular music titles, can be stored in the memory.

  • the storage requirement for audio data is reduced by a factor of 10 using MP3 compression, so that audio data from around 100 standard CDs can be stored on a 6 GB hard drive. With an average of 15 music tracks per CD, this is 1500 tracks.
  • a measure of the user's listening (or audio data) or viewing habits (in the case of video data) is derived from the user's actions. It is advantageous that a single operator action, e.g. the actuation of a single button, sufficient, the enormous amount of data in a meaningful

  • the preferred titles are determined individually for each user.
  • the possibility is provided to block the adaptation of the data stock to the habits, so that a user who is not the actual owner of the data stock cannot change the access sequence during playback.
  • individual titles can be selected as particularly preferred and / or as particularly uninteresting.
  • the user can save data permanently by means of a further operator action, regardless of the degree of preference.
  • Particular advantages result in the reproduction in that a value assigned to the data, which represents the degree of preference by the user, is evaluated, and the sequence of the data in the reproduction takes place in accordance with this value.
  • the user when the data is recorded, the user is spared preparatory measures due to the permanent storage, possibly also in the background. Since this solution can overflow the memory, it is advantageously ensured by adapting the order of access to the data stock to the user's hearing or viewing habits that only the data that has little or no significance for the user is deleted , In this way, the database that is being accessed is kept up to date. In this context, it is also advantageous that the user does not have to worry about which data has to make way for the new data in the event of an impending memory overflow.
  • the data is stored in compressed form in the storage medium, for example MP3-compressed.

  • the device or device system consists of a memory with a large storage capacity, for example of several gigabytes. Depending on the embodiment, this memory is a DVD drive or a hard disk.
  • the memory is connected to at least one audio source 12, 13 via a data connection 11, preferably a data bus.

  • Embodiment a single operator action is sufficient, for example, the actuation of a single key or in the case of a voice control, the specification of a single command in order to bring an access sequence into the data volume.
  • the operator action mentioned is an operator action with which the user deliberately aborts the playback of the data. This suggests that the user of the reproduced file eats less importance, so that it can be classified as less preferred.
  • the stored data is therefore reproduced on the basis of information which represents the user's listening habits. This is called the degree of preference below.
  • All saved files i.e. in the preferred embodiment, all stored music tracks are automatically provided with a degree of preference.
  • the different values form a hit list of the files in the memory which are used for playback.
  • playback is carried out at random, i.e. all saved files have the same playing probability.
  • a second possibility is to display the value according to the degree of preference. This means that the hit list is played through from top to bottom, starting with the files with the highest level of preference.
  • a combination of the random principle and the degree of preference is also used. This means that files with a higher preference level value are more likely to be played than others. The latter is particularly suitable for the present application. The favorite files are then played more often, but files that have not been played for a long time are also played back.
  • the procedure is accordingly, with the playback taking into account the viewing habits of the user.
  • the functions described with regard to the reproduction and the adaptation of the reproduction to the listening habits of the user are implemented by means of programs on a microcomputer which, depending on the version, is arranged in one of the audio sources or in the area of the memory or in a central unit for controlling it, which performs the operating actions evaluates the user and carries out the measures derived from it.
  • Such a program of a microcomputer is sketched in FIG. 2 for playback using a flowchart.
  • the flowchart in FIG. 2 runs when the playback mode of the device is switched on.
  • the title selection is carried out according to one of the above-mentioned playback programs. In the preferred exemplary embodiment, this title selection takes place at random on the basis of a value representing the user's listening habits.
  • the files (titles) stored on the memory are sorted on the basis of this value (PKT) in a list from which files to be played back at random are selected. Files with high numbers of values are weighted with a higher probability of playback.
  • the selected title is reproduced in step 102 by the data being played back via the reproduction unit. It is then checked in step 104 whether the reproduced title has ended (either by aborting or by playing completely). If this is not the case, the data continues to be reproduced. If this is the case, the program is repeated with step 100 and a further title is selected. The program also ends when you exit playback mode.
  • the value representing the user's listening habits adapts individually to the user's listening habits.
  • the change in the value is derived by evaluating the operator actions during the playback of a file (title).
  • a basic example is outlined using the flow diagram in FIG. 3.
  • a step 105 checks whether an operator action has taken place from which a decrease in the PKT value can be derived. Such an operator action is present, for example, when the
  • the value PKT is decremented in step 106. If such an action is not recognized, it is checked in step 107 whether an action has taken place which leads to an increase in the value PKT. Such an action can be assumed, for example, when the title being played has been heard completely, or when a corresponding key has been pressed or a corresponding command has been entered, which deliberately expresses the preference for the piece currently being played. In this case, the value PKT is incremented in step 108.
  • step 107 the sketched program part is run through again, and when the title ends (also by aborting) the sketched program is only called up again during the playback of the newly selected title.
  • the value PKT (degree of preference) is carried out on the basis of the actuation of the at least one single key of the device.
  • an existing standard key for example the one that implements a SKIP function, is used. This button is pressed by the user whenever he no longer wants to hear the title currently playing, i.e. does not prefer this title at the moment. Therefore, in the preferred embodiment, the degree of preference is changed according to the following rules.
  • the value is increased automatically when the played title has been completely saved from the memory.
  • the value is automatically reduced when the user makes a jump to the next track.
  • the change in the degree of preference takes place with every replay and with every action.
  • a positive rating of reproduced titles is provided. Since with the negative rating outlined above, it can take a long time for titles located further back in the hit list to move upwards with the TOP button for the user
  • Play the corresponding title The same applies in a further exemplary embodiment with regard to the lowering of the value.
  • a so-called FLOP button is provided, the actuation of which gives the user the option of reducing the degree of preference, preferably reducing it to 0 and thus effectively deleting the title from the playback memory or even triggering a deletion action. This gives you the opportunity to quickly remove unwanted titles from playback access. Depending on the version, this action is also possible during and / or independently of the playback of the title.
  • the user is given the opportunity to specifically protect certain tracks from inadvertently reaching the end of the playlist and then accidentally deleting them when the memory is completely full.
  • a further key the archive key, is therefore provided. If this is pressed when playing a title, this causes the archive status to be assigned to this title. Titles with this status are blocked for automatic deletion in the event of an impending memory overflow and are not deleted regardless of the value of the degree of preference. In a particularly preferred manner, when titles with archive status are played back, this status is reported optically in order to give the user the possibility that when the
  • Archive button is no longer necessary for this title.
  • the archive status is reset by pressing the SKIP button or the FLOP button.
  • the archive function can be used during and / or independently of the playback of the title.
  • the program described in FIG. 4 also runs during the playback of a title. First, it is checked in a first step 110 whether the system is in the locked mode. If this is the case, the program is ended for the playback time of this title, since it is not possible to change the degree of preference. If the system is not in the locked mode, it is checked in step 111 whether the archive key has been pressed. If this is the case, the archive status is set in step 112. If this is not the case, it is checked in step 113 whether the SKIP key has been pressed. If this is the case, the value PKT is decremented in step 114. If the SKIP key is not actuated, a check is made in step 115 as to whether the TOP key is actuated. If this is the case, the degree of preference value is increased in step 116, preferably set in the vicinity of the maximum value. If this key is not pressed, it is checked in step 117 whether the
  • step 118 the degree of preference value is decremented in step 118, preferably set to 0. If the FLOP key is not pressed, then a check is carried out in step 119 to determine whether the title has ended. If this is the case, the degree of preference is increased in step 120. If the title is not ended, then for the duration of the playback of this title as well as after steps 112, 114, 116 and 118
