Description
Technical field
The present invention relates to a kind ofly be used for the Study document name and, especially in playlist, as especially according to as described in the aforementioned part of claim 1 for the optimization process file reduces the method for filename length.In addition, the invention still further relates to a kind of device that is used to carry out said method.
Background technology
In the prior art, become known for media file, for example the player of music file, video file and/or known image file.
As this player, for what people knew for example mancarried device arranged, as the MP3 player or have the mobile phone of corresponding function.This player for example is so-called MP3 player, for example the well-known Ipod device of Apple.For this player, the file that can play transmits by the data transmission in the integrated storer of this device or the mobile memory card by this device provides.
In addition, the player that is used for removable media is also for people know, as is used for CD, DVD etc., and wherein the file that can play is present in movably on medium such as the CD.By in player, inserting removable media, can provide file available on it to play being used for.
Usually, the available file that is used for playing on this device can exist with various file layouts basically, as with " .mps ", " .wma ", " .wav ", " .m3u ", " .pls ", " .asx ", " .wpl " or " .aac " file layout.File also can be present on various for example removable data carriers or the medium.
In order to generate at least one the selection of preferred media file is play being used for, use is also referred to as so-called the rendition list of playlist, so that distribute various files and/or so that select and definite order of the file that is used to play with predefined choice criteria.By using so-called playlist, therefore can from a large amount of available files, select and the selection targetedly and/or the ordering of allocate file, so that for example play or show described selection and/or ordering.
At this, playlist also is a file, and this playlist also can be stored on the data carrier except media file, so that use it by player, wherein, described playlist also comprises the path of the memory location of pointing to selected media file.Advantageously, playlist can on the player that will use and/or with its independent device on processed and/or editor on computers or in network for example.Playlist also can be stored on computers or in the network.In order to play, can for example media file and at least one playlist be transferred to player subsequently by data carrier or data transmission.
If for example create this playlist on computers or in the network, then this playlist has the memory address separately or the path of selected media file.Because file is stored on the mass storage as hard disk or analog etc. usually, so the path of memory location has typical data structure in this respect, as C: catalogue ... 1 sub-directory ... 11 sub-directory ... 111.At this, this address descriptor the part of bibliographic structure of employed computing machine, this part has the respective path of the media file that is stored in the there.
For the media file that in player, uses this playlist and select on player, to play, then access playlist, select clauses and subclauses and select the file of these clauses and subclauses, and the memory location is used as indication and is returned to player.The address of described media file is illustrated by this indication, and player can be with corresponding file load in its storer and play.
Yet, the problem of this player or application is: if be used for record data or be used for executive routine or the available memory of application is limited and deficiency, need then to tolerate that this analysis ability that also shows this player and/or application is severely limited owing to the restriction of this respect of storer deficiency.
For example, CD Player or MP3 player have the CD-MP3 chipset that is generally 1M bit (=128k byte), and this is used in the application of various parallel runnings.These application examples are the surge protection of use, playlist analysis or the mancarried device of routing table in this way.Because this multi-functional use to limited storer, the performance of player is corresponding to be restricted.This point can be because thereby filename be long relatively and correspondingly need a large amount of storage spaces and further aggravated.
Therefore, usually need to shorten the filename of media file, so that under the acceptable situation of performance, a spot of free memory is enough, wherein, the shortening of filename length should be carried out with respect to the possible in principle filename length that can be used in general program or application, for example uses in the CD burning program on computers.
Because filename has for example been used by data source, program or by internet radio and has been provided in advance, manually reducing the filename that the heap file name surpasses the file of pre-set length is a quite worthless process, and this process is decided also very consuming time on the quantity of file.
In addition, by the known a kind of apparatus and method of EP 0 944 903 B1, can distribute the also title of distributing individually of service recorder carrier whereby.Yet the cost of doing so individually is very high, and under the situation of arbitrarily big quantity data or record carrier, this can't carry out, because the cost of getting in touch therewith can not be accepted by the user.
