Description

Technical area

The The invention relates to a device and a method in particular to select and play files or data, such as For example, from music files, image files or movie files.

State of the art

It electronic devices are known, by means of which, for example Music pieces in the form of files are selected and be played. The data are in particular the pieces of music as files in front. The files are preferably on one File carriers, such as a CD, DVD, a hard disk, a Chip card, an SD card, an MMC or a USB medium.

In such electronic devices, the files may be selected and played back by an operator, or played in sequence, or in a so-called random or shuffle mode in which the files are randomly selected from the existing file set and played where already played files are not re-selected and played during a run of such a random or shuffle mode. Thus, the files, in particular of the pieces of music, are randomly selected and played back but not selected and played back more than once (see eg. US Pat. No. 5,408,448 ).

The electronic devices have a processor, which is the already selected and played Must remember files in case it's a random number a file that has already been selected and played later again is selected, this file will not be played again. So the processor has to play the already played files or Remember pieces so they will not be the same again Run to be played.

To are memory, such as RAM or Flash / EEPROM, in the electronic Device provided and connected to the processor, on which Data are stored, which already selected Represent files, so that at a later time Time can be checked, whether a selected File not already selected and played before has been.

There The electronic devices are getting more and more files on their computer Can store hard disks or other data stores, it is with the available random access memories the processors are not possible all already played Save files to memory because then the memory reaches its capacity limit and then no further information about already played files more can be stored. So today have so-called MP3 players already have hard disk capacities as mass or Data storage of up to 80 GB, so that on it several tens of 10,000 music pieces or image files can be saved.

According to the invention, the object is achieved with respect to the method with the features of claim 5. The inventive method for selecting and playing files or data provides a device with a processor and a working memory, wherein playable data or files are stored on a mass storage device and to play loaded into the memory of the device, wherein in a mode of operation of the random selection of the data or files to be played a file or a record selected and this or this with an on is compared to a register file, the entry representing that the file or record has already been played, the register file being stored on the mass storage on which the playable files or data are also stored.

there it is useful if the selection by means of a Random generator takes place.

Also it is useful if in the case that exam indicates that the file is already marked in the register file is, a reselection of a file is performed. Also it is expedient, if in case, that the Check shows if the file is not already in the Register file is marked or recorded, the file is played and an entry is made in the register file.

Farther it is useful if the file contains a music file, an image file or a movie file is.

advantageous Further developments are described in the subclaims.

Brief description of the drawings

 below the invention is based on an embodiment explained in more detail with reference to the drawings. Show it:

1 a block diagram for explaining the device according to the invention and

2 a block diagram for explaining the method according to the invention.

Preferred embodiment the invention

The 1 shows a block diagram in which an electronic device 1 is represented, by means of which files are playable, such as music files or other files can be displayed, such as image or movie files. The electronic device 1 has a processor 3 and a memory 4 on, where files that are processed by the processor, in the memory 4 getting charged.

The device continues to look 1 a mass storage 5 such as a hard disk, a memory card, a usb memory oa, being the mass storage device 5 is writable again.

If a shuffle or random mode is selected, see 2 , the processor selects from a file in which the files stored on the mass storage are listed or information is listed in this file or list from a file. This will then be with a file content of a register file 6 compare in which the already selected and played files are listed. This file is or is inventively on the mass storage 5 created or stored. Is the selected file not yet in the register file? 6 listed, the file is played and in the register file 6 an entry is made to the selected and played file. If the file has already been played and there is a corresponding entry in the file 6 before, another file is selected via the random mode and it is checked again whether this file has already been played. The register file 6 thus represents a file which stores the files selected and played in the course of a shuffle or random mode run. Also, beyond a run of such an operating mode, the file may save the already selected and played file, if desired. Otherwise, the file may also be deleted for content at the end of such mode of operation.

By storing the file 6 Preferably, a file size may be selected on the mass storage on which the files to be played are stored, so that all selected and played files in this file can be recorded and taken into account without limitation of the file size.

The 2 shows a block diagram 10 a method according to the invention, wherein in block 11 the procedure is started. By starting in block 11 a shuffle or random mode is started as described above. In step 12 For example, a file is randomly selected from the set of files stored on a mass storage device. In block 13 is checked against a file, whether in block 12 selected file has already been selected and played in this shuffle or random mode run. This file is inventively stored on the same mass media on which the playable data are stored. If the file has already been played, the check will be confirmed and it will be at block 12 and a new file is selected, for example, at random. Will the test of block 13 If the answer is NO, the file will be loaded into the RAM of the processor and played back, see block 14 , Subsequently, an entry is made in the register file 6 in which the already played files are stored, see block 15 ,

Thereafter, if the shuffle or random mode has not been completed and the selected file is finished in playback, with block 12 continued.

It It should be noted that the concept of playing is not limited to Music files, but in the same way for example Image files or movie files applicable in a shuffle or Random mode can be displayed one after the other.
