(5) embodiment
Fig. 1 selects the structure chart of the applied audio player of player method for the audio file with bibliographic structure according to the present invention.Include light picker 11, Play System 12, microprocessor 13, memory 14, LCD (LCD) 15 etc. such as insert in the MP3 player that CDs such as MP3-CD 10 have been installed.
In addition, on the CDs such as above-mentioned MP3-CD 10 in the mp3 file of record storage, as shown in Figure 2, comprise and record heading message and MP3 voice data, and identification information.Can comprise corresponding content information (title_info) and corresponding singer informations (singer_info) such as singer's name and singer's resume such as recording bent name of audio frequency and reproduction time in the above-mentioned identification information.
In addition, the mp3 file of many head of record storage etc. can have bibliographic structure on the CD 10.As shown in Figure 3, the bibliographic structure of mp3 file be according to PVD (Primary volume descriptor: the initial volume descriptor) in the information ' guidance information that writes down on the 157-190 ' byte defines.
Such as, in PVD (the Primary volume descriptor) information ' comprise in the 157-190 ' byte and record total data length, the root position, time, file mark (flag), file unit size, insertion position (interleave), volume (volume) sequence numbering, contents such as the length of file ID, in addition, comprise in the root and record current location, higher level's directory location, the position of each catalogue and size, and the position of each file and size information etc.
In addition, comprise in the general catalogue below the above-mentioned root and record current location, higher level's directory location, the position of each catalogue and size, and the position of file and size information etc.Also comprise in subordinate's subdirectory of above-mentioned general catalogue and record current location, higher level's directory location, the position of each catalogue and size, and the position of each file and size information etc.
In addition, record management is to the guidance information of the bibliographic structure of above-mentioned CD 10, such as in the root register, as shown in Figure 4, comprises successively and records synchronizing information, heading message, subtitle information.Also comprise then and record the current directory record, higher level's catalogue record, the subprime directory record, subprime directory record size, and directory name information etc.
Then, above-mentioned microprocessor 13 reads the guidance information of record on the above-mentioned CD 10, download to above-mentioned memory 14, then, with reference to this guidance information, judge the bibliographic structure of the how first MP3 that writes down on the identification CD, such as judge the bibliographic structure of identification by said process, as shown in Figure 5, comprise below the root (ROOT) and record a plurality of general catalogues (DIR 1, and DIR 2, DIR3, ..., DIR N), below each general catalogue, record 6 subdirectories (Sub-DIR 1 such as comprise below the 4th catalogue (DIR 4), Sub-DIR 2 ..., Sub-DIR 6).
And, comprise in the 5th subdirectory (Sub-DIR 5) in above-mentioned 6 subdirectories record how first mp3 file (MP3 File 1, MP3 File 2 ..., MP3 File N).For CD with above-mentioned bibliographic structure, above-mentioned microprocessor 13 receives the predefined particular key of user, such as when " catalogue choice menus key ", having stored the information of above-mentioned memory 14 into will read with JPEG (a kind of picture format) image of file shape, as shown in Figure 6, after the directory menu picture of step 1 generates, show by above-mentioned LCD 15 outputs.
At this moment, above-mentioned LCD 15, as shown in Figure 6, to show " ROOT " menu item that can directly revert to root with the jpeg image of file shape respectively, with " Current " menu item that displays the name of the current directory, and a plurality of general catalogue below the root (DIR 1-8) etc., also be provided with the menu button of arrowhead form in addition, be used for selecting the picture of forward/backward (pre/next) page or leaf to show.
In addition, when the 4th catalogue (DIR 4) below the user passes through the directory menu picture and selecting designated root catalogue of above-mentioned steps 1, the jpeg image of the file shape of 1st to 6th subdirectory (Sub-DIR 1-6) of above-mentioned microprocessor 13 below above-mentioned memory 14 reads the 4th catalogue, as shown in Figure 6, after generating the subdirectory menu screen of step 2, by above-mentioned LCD 15 outputs and demonstration.
If the subdirectory menu screen of user by above-mentioned steps 2 selects to have specified the 5th subdirectory (Sub-DIR 5), above-mentioned microprocessor 13 just to read and plays the 1st first mp3 file (MP3 FILE 1) in the how first mp3 file below the 5th subdirectory.This moment, above-mentioned microprocessor 13 retrievals confirmed to comprise in the 1st first mp3 file (MP3 FILE 1) identification information of record, with bent name of audio frequency and reproduction time information etc., as shown in Figure 6, output is shown in the directory menu picture of step 3, and the user just can simply discern the audio played at present song.
As a reference, can a greater variety of shapes of additional record or additional information in the above-mentioned menu screen that is output demonstration, the present invention can be applied to multiple recording medium and the audio player beyond the CD such as MP3-CD.
Select player method to have very high practical value according to aforesaid audio file with bibliographic structure of the present invention.Read the guidance information relevant from the CD that records how first MP3 audio file with this bibliographic structure with bibliographic structure, and download in the device, then, generate and show multistage directory menu picture, thereby can be so that the user can select to specify the catalogue that needs successively, and read automatically simultaneously and play the 1st first mp3 file that comprises in the subordinate subdirectory of user by the selected appointment of above-mentioned multistage directory menu picture, thereby can make the user who has audio players such as MP3 player can be by multistage directory menu picture, the catalogue of own needs is specified in easy selection, and in addition can also be easier read play the mp3 file that comprises in the subordinate subdirectory.
Though the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, should understand and wherein can make variations and modifications and do not break away from the present invention in a broad sense, so be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the distortion of the above embodiment.
