Description of the Invention: [Technical Field of the Invention] The present invention relates to a media list generating apparatus and method. [Prior Art] With the development of digital technology, digital audio, such as digital video, e-books, and electronic pictures, are widely used. Digital media can be stored on hard drives, CDs, and web servers. Digital media can also be used in portable devices such as personal digital assistants (PDA), portable audio playback devices, and portable e-book readers. Currently, a CD (Compact Disk) can store 140 MP3 (MPEP layer three) audio files, and a hard disk audio player with 10G storage space can store 2000 MP3 audio files. The capacity of storage devices continues to increase. For example, a personal computer with 80G storage space will be able to store 16,000 audio files, so it will be difficult for users to organize, classify and maintain such a large number of digital media. In turn, it can be quickly and easily identified. It is more important to choose an audio document that users like. Typically, the audio player sorts by the field content in the audio document tag and creates a list. For example, the classification criteria for audio broadcasts usually include audio rights names, artist names, album names, and genres, which can be popular, classical, rock, jazz, and the like. With the audio document management program, the personal computer enables the user to create and edit a playlist. The playlist can be downloaded to the audio playback device. The audio player can also browse and select audio files by the above categories. However, when a user needs to play an audio document, it is still necessary to remember the category and path of the audio document. When there are many categories of audio signatures and subcategories, it is still cumbersome to select an audio file that you want to play. When playing by category, you will need more manual skipping when you encounter an audio file that you don't like. The user can also select the current favorite audio document and merge it into a playlist, and the user still needs to manually perform when the playlist needs to be modified or updated. A method of automatically generating a playlist is disclosed in U.S. Patent Application Publication No. 2003/0221541, the entire disclosure of which is incorporated herein by reference. The method causes the user to first select a plurality of seed audio documents, including the user desire audio file and the non-desired tone, and the user can also set weight values for the audio floor to determine the relative importance of each audio document. Each audio document is then compared to the plurality of seed audio documents, and an audio document similar to the desired audio document and not similar to the non-desired audio document is analyzed and identified to determine the audio document desired by the user and to create a playlist. The method disclosed in the above application file is to manually select a plurality of seed audio files, and by using the plurality of seed audio files as reference audio files, select an audio document similar to the desired audio document and not similar to the non-satisfied audio document, thereby generating a play. List. This method has the following shortcomings: Firstly, it is necessary to manually select the seed audio file, and the pace of life is accelerated. 'People often require the use of some electronic devices to be simple and fast; in addition, the number of audio files stored by the audio player is large, and the audio text; The storage path of the slot is complex and variable, which not only takes a long time to select the seed audio file; in addition, the method fails to automatically obtain the user's favorite audio file by the history play record, so that the selected audio file is not sufficient. Reflect the user's preferences. SUMMARY OF THE INVENTION In view of the deficiencies of the above application documents, an audio playback device of the present invention automatically generates a weighting value of each audio file by operation of a user during an audio file playing process, and obtains a weighted value of a preset number of audio files and a plurality of field contents in the tag, and thereby generating a weighting value of each sub-item in the complex weighting value setting table; traversing the complex weighting value setting table to generate a comprehensive weighting value of each audio document; and a comprehensive weighting value of each audio document Automatically select _ complex audio files to generate a playlist. Make the audio text in the playlist more in line with the user's actual preferences. The present invention provides a playlist generating method for generating a control signal for generating a playlist in response to a user input. In response to the control signal, the initialization complex weighting value setting table 'the complex weighting value setting table respectively records the correspondence between the field contents of the audio document and the weighting value. Each audio document is sorted by a weighted value size. The weighted value and the plural field content of the preset number of audio files are sequentially obtained. Thereby, the weighting values ' of the respective sub-items in the complex weighting value setting table are calculated and stored in the corresponding weighting value setting tables, respectively. Traversing the complex weighting value setting table, calculating a comprehensive weighting value of each audio document, "generating a playlist by weighting values of each audio document" 7 1315036 * The present invention also provides a playlist generating device including a memory, an input A unit, a control unit, and an audio document management unit. The memory stores a plurality of audio files and a plurality of weighting value setting tables, and the complex weighting value setting table records the correspondence between the field contents of each of the audio files and the weighting values. The input unit generates and sends a control signal for generating a playlist in response to the user's rounding. The audio document management unit receives the control signal under the control of the control unit to initialize the complex weighting value setting table; sorts each audio document by a weighting value; and sequentially obtains a weight value of a preset number of audio texts And a plurality of field contents; thereby calculating a weighting value of each sub-item in the complex weighting value setting table; traversing the complex weighting value setting table, calculating a comprehensive weighting value of each audio document; generating a playing by weighting values of each audio document List. The invention automatically generates a weighting value of each audio document by the user's preference, and then generates a playlist by weighting the plurality of audio files, so that the audio text in the playlist is more in line with the user's preference. Embodiments of the invention will be described. [Embodiment] A block diagram of an audio playback device 10 of the present invention is shown in the first figure. The audio playback device 10 includes a memory 11, an input unit 12, a control unit 13, an audio document management unit 14, a decoder 15, a digital-to-analog converter 16, and an audio output unit 17. The memory 11 stores a plurality of audio files and a plurality of weighting value setting tables; a weighting value field is set in the label of each audio floor, and a comprehensive weighting value of the audio file is recorded; the complex number plus the weight setting table respectively records the audio document The correspondence between the content of one field and the weighted value, including the singer, genre and rhythm. The input unit generates and transmits a corresponding control signal in response to the user's input. The control unit 13 identifies the control signal sent by the input unit 12, and controls the memory 11 and the audio document management unit 14 in response to the control signal. The audio file management unit 14 obtains the weighted value and the plural field content of the preset number of audio files under the control of the control unit 13; thereby calculating the weighting value of each sub-item in the complex weighting value setting table; traversing the complex number The weighting value setting table calculates a comprehensive weighting value of each audio floor; and generates a playlist by the integrated weighting value of each audio document. The decoder 15 is used to decode an audio document. The digital to analog converter 16 is operative to convert the digital signal of the audio document into an analog signal. The audio wheeling unit 17 allows the user to connect the tone 8 (S) 1315036 frequency playback device to an audio system or earphone, amplify the analog signal and provide it to the audio system or earphone for playback. As shown in the second figure, it is a block diagram of an audio file management unit of the audio playback device 10 of the present invention. The audio file management unit 14 includes a weighting value generating module 14A, a sorting module 141, a weighting value setting table updating module 142, a weighting value adjusting module 143, and a playlist generating module 144. The weighting value generating module 14 is configured to automatically generate a weighting value of the audio file by the operation of an audio file by the user; for example, in the embodiment, the weighting value generating module 140 plays the audio file by the user. The adjustment of the volume during the process generates a weighted value of the audio document. The sorting module 141 sorts each audio_text broadcast by the weighting value. The weighting value setting table updating module 142 sequentially acquires the weighting value and the plural field content of the preset number of audio files, for example, may be sequentially obtained according to the weighting value size of the audio document; and thereby calculating each of the complex weighting value setting tables The weighted value of the child. The weighting value adjustment module 143' traverses the complex weighting value setting table, and calculates a comprehensive weighting value of each audio file in the audio playback device 10. The playlist generating module 144 generates a comprehensive weighting value of each audio file. playlist. As shown in the third figure, the main flowchart of the generated playlist of the present invention is shown. The input unit 12 generates and transmits a control signal for generating a playlist in response to the user's input (step S20). Referring to the eighth to tenth diagrams together, in response to the control signal, the complex weighting value setting table is initialized to initialize the weighting value corresponding to each sub-item in the complex-weighted value setting table to zero (step S21). Each audio document is then sorted by the weighted value size (step 522) » The weighted value and the plural field content of the preset number P of audio files are sequentially acquired (step 523). The weighting value of each sub-item in the complex weighting value setting table is calculated by the weighted value and the complex field content of the acquired audio file. The content of the field includes a singer, a genre, a rhythm, and the like (step S24). The weighted values of the respective sub-items are stored in the corresponding weighting value setting table (step 525). The complex weighting value setting table is traversed to calculate a comprehensive weighting value for each audio document (step 526). The audio file is selected by the integrated weighting value of each audio file to generate a playlist. The method for generating a playlist may be: selecting a specific number of audio files with a larger weight value to generate a playlist; or calling a random function selection The audio document generates a playlist, at which time the weighted value of the audio document will be used as a parameter in the random function (step S27). The 9 C§ 1315036 playlist allows the user to manually edit. As shown in the fourth figure, a flowchart of generating weighting values for each sub-item of the complex weighting value setting table of the present invention is shown. First, the audio document management unit 14 acquires the weight value of an audio document (step S30). It is determined whether the weighted value of the audio channel is greater than a predetermined value κ (step S31). If the weighted value of the audio textbook is not greater than a preset value K', the weighting value of each sub-item in the complex weighting value setting table is the final value; if the weighting value of the audio document is greater than a preset The value K 'accumulates the number n of acquired audio files once (step S32). Then, one of the field contents of the audio document is acquired (step S33). A weighting value setting table corresponding to the content of the field is found (step S34). The weighted value of the audio document is added to the weighted value of the same item as the content of the field (step S35). It is judged whether or not the sound reduction document has a spring field content that has not been acquired (step S36). If the audio file has the field content that has not been obtained, the process returns to step S33; if the field contents of the audio text library are all acquired, it is determined whether the number N of the obtained audio files is less than a preset number p (step S37) If the number N of the acquired audio files is less than a preset number p, the flow returns to step S3; if the number N of the acquired audio signatures is not less than a preset number p, the flow ends. After the process ends, the weighted value corresponding to each sub-item in each weighting value setting table is the final value. Certainly, when obtaining the weighted value and the content of the complex field of the audio file, it is not necessary to determine whether the weighted value is greater than a preset value K, that is, only the weighted value and the plural field of the audio file of the preset number p can be obtained sequentially. The following is a flow chart of adjusting the weighting value of each audio file in the audio playback device 10 according to the present invention. First reading an audio text in the audio playback device (step S40) to obtain the content of the plurality of fields of the audio text, the content of the field includes _ singing old, _ party = playing, etc. (step s price please - and refer to the first person From the figure to the tenth figure, the complex weighted L value setting table is traversed, and the addition of the sub-item of the sub-item of the audio document (step S42) is weighted by the sub-item corresponding to the content of each field of the audio document. Value, using an algorithm to calculate the integrated weighting value of the audio document; for example, the weighting value corresponding to each field content may be added to 'calculate the integrated weighting value of the audio text broadcast; or the weight of each field content may be weighted accordingly The value is multiplied by the weight percentage and then added to the total weighted value of the audio document, wherein the weight percentage indicates the importance of each field content 1315036

Obtain the volume when the audio tree is finished playing, and use the volume as the - standard volume, which is the most comfortable volume of the user (4) music in the case of the pass* (step S52). Read and decode the next audio text (fine S53). Output the audio floor (face SM). The control unit 13 detects and adjusts the volume control signal in real time (step sss). If the control unit η does not detect the control signal for adjusting the volume, the flow returns to step S54; if the control unit 13 makes the tone-distribution red (four) 峨, the sound processing unit 14 acquires the adjusted volume. (Step Na. The volume after the adjustment is subtracted from the standard volume, and the volume adjustment is adjusted to 13⁄4 degrees (step S57). Please - and refer to the seventh figure 'Reading the relationship between the volume adjustment amplitude and the weighting value table Obtaining a weighting value corresponding to the volume adjustment range (step S58) » the audio text file management unit 14 determines whether the weighting value is equal to an original weighting value of the audio document (step S59). If the weighting value is equal to the audio text broadcast The original weighting value, the flow jumps to step S61; if the weighting value is not equal to the original weighting value of the audio document, the weighting value of the audio document is updated (step S60). The audio document management unit 14 determines whether the audio document is The playback is completed (step S61). If the audio file is played, the flow returns to step S53; if the audio file has not been played yet, the flow returns to step S54. During the playback, if the audio playback is loaded After receiving the pause or stop signal sent by the input unit 12, the audio file is paused or stopped. The seventh diagram shows the corresponding relationship between the volume adjustment amplitude and the weighting value of the present invention. Correspondence between the volume adjustment amplitude and the weighting value. For example, when the volume adjustment range is between 7 and 9, the corresponding weighting value is 3^. The weighting value represents the preference of the 1315036 household to the far audio domain. Under normal circumstances, when the user listens to - like the audio document, the volume will be turned up; when the user listens to the __ sound, the original sound will be kept or the volume will be reduced. - such as ^8 to 10 Figure 2 is a schematic diagram of the complex weighting value setting table of the county invention. The complex weighting value setting table respectively records the pair of the singer, genre and rhythm of the audio file and the weighting value. The singer's child includes the plural singer name. The singer's children may also include the index number of the plural singer, each of which corresponds to a singer's name. The genre's children include rock, pop, jazz, etc. The children of the rhythm include rush, fit In summary, the device and method for playing the lining table proposed by the present invention can indeed meet the patent requirements of the invention patent application.
