Embodiment
Below will combine accompanying drawing and embodiment that the present invention is explained in further detail for the ease of it will be appreciated by those skilled in the art that.
The dynamic media library management method of disclosed vehicle entertainment system is the user two kinds of different patterns of on storage medium, setting up media library is provided.A kind of pattern is to be to lead and the high molar formula of the stacked structure of arranging in pairs or groups with As soon as possible Promising Policy memory capacity, i.e. Mode A; A kind of pattern is is main with the high in efficiency and convenience and the high effective model of collocation flush system structure, i.e. Mode B.The user can set up and the use media library, to make things convenient for the user and to raise the efficiency based on actual needs Dynamic Selection Mode A or the Mode B of oneself.
As shown in Figure 1, when the vehicle mounted multimedia entertainment systems recognizes the External memory equipment access that is loaded with multimedia file, the prompting user is selected to be provided with the mode that media library is set up.During practical implementation, can be employed in the mode that increases media library type selecting item in the menu option and supply the user to select.When the user wants on the storage medium of appointment, to set up media library, interactive module remind the user select the pattern of setting up in dynamic media storehouse, user open menu option can preference pattern A or Mode B carry out developing and managing of dynamic media storehouse.
Wherein, The method that the A pattern develops and manages media library is: the root directory of the memory contents in the External memory equipment is read in (1); Set up the root directory node, the file under (2) traversal root directory is if the file that reads is a catalogue; The then corresponding directory node of setting up this sub-directory also adds it in directory listing of current directory node and gets into this catalogue and read, and returns current directory after the completion and continues to read other clauses and subclauses (degree of depth traversal); If what read is not catalogue, then skip; Traversal until whole memory device finishes, and step (2) back media library is set up, and this media library is a stepped construction, also must successively carry out when browsing, and the directory listing that this pattern forms is shown in Fig. 3 left side.(3) in directory listing, select playing catalog, get into catalogue and read selected catalogue,, then be created as the sub-directory node of media list if the file that reads is a catalogue according to classification such as audio/videos; If what read is the media file node that the selected type media file then is created as media list, promptly set up current playlist after reading completion, supply the user to select to play.For example comprise FILE1, FILE2, three media files of FILE3 under the catalogue FD6; Playing catalog FD6 as selecting in this step; Then playlist from root directory begin need be successively through catalogue FD2-FD6 again to file FILE1, FILE2, FILE3; Form the playlist under the current directory FD6, shown in right side among Fig. 3.Media play is selected by end user in this playlist.
Mode A is actually the original structure that keeps in the medium, and the implementation that forms through chdir tabulation and playlist realizes the high effect of holding.Like a some open file folder FD1, comprised file FD6 and file FILE1, FILE2, FILE3 below, be to can't see file content under the file FD6 at this moment, can not expend the space yet and store the content among the FD6.Only there is a some open file folder FD6 just can browse to the fileinfo in this document folder and stores.Under this situation, suppose that directory listing and media play list all are 10000 storage spaces, can support the file amount of 10000x10000 so, capacity is equivalent to enlarge 10000 times under the equal storage space.
Wherein, The method that the B pattern develops and manages media library is: the root directory of the memory contents in the External memory equipment is read in (1); Set up the root directory node, the file in (2) traversal memory device is as if the catalogue that is that reads; Then corresponding set up the directory node of this sub-directory and add in the directory listing and get into this catalogue this its read, return current directory after the completion and continue to read alternative document (degree of depth traversal); If read for media file, then media file is divided classification such as audio/video to join respectively in the audio/video media listed files of present node; Traversal until whole memory device finishes, and step (2) back media library is set up, and this media library is the tiling structure; Promptly all directory node all are placed on ground floor side by side; All Files all is placed on the second layer under the catalogue, and is as shown in Figure 4, can once travel through all catalogues when browsing.(3) based on directory listing successively with media file tabular assorted linking under each catalogue; Form classification playlists such as audio/video, after selecting audio/video, the audio/video tabulation of selecting is set to current playlist; Realize playing, as shown in Figure 5.
The characteristics of Mode B are efficiently being main, when media library is set up, through traversal once; Just needed media categories is extracted and accomplished the foundation of directory listing and playlist, operating process is afterwards all controlled by pointer, need not redistribute the space and set up new tabulation; Only needed for two steps just can realize various functions; Functional efficiency improves greatly, plays as realizing selection spare folder, only need directory pointer < PLAY1>be moved to selected file folder node; The media file node that playing pointer < PLAY2>is moved to selected node just can realize that node is accepted or rejected and also can freely be controlled.The user only needed for two steps just can find own required media file, and like the file FILE7 among Fig. 2,3, stepped construction needed for five steps just can find, but used the tiling structure only to need for two steps just accomplished.According to the degree of depth of supporting ten layers, browse efficiency can improve 60%.
Mode A is different with Mode B to be: one is to select type (audio frequency or video) to go to read current directory more earlier; Have only just including in the tabulation of coupling; A kind of is in traversal, just according to the type of all needs dissimilar tabulations to be set up respectively, selects type afterwards again as long as playing pointer is moved in the tabulation of corresponding types.
The preferred version that the foregoing description is realized for the present invention; And indefiniteness is exhaustive, and the present invention can also have other variations under same idea, need to prove; Conceive under the prerequisite not breaking away from the present invention, any conspicuous replacement and subtle change are all within protection scope of the present invention.
