Method for realizing random playing in multimedia player

Abstract

The invention relates to a method for realizing random playing in a multimedia player, which comprises the following steps: initializing an ID list of document by a controller; generating a random number which is less than the document number range of documents which are not played by a random number generator; extracting the ID of a corresponding document of the random number from the ID list ofthe document by using the random number; exchanging the ID with IDs which are sequentially counted from the rear part in the ID list of the document and are not exchanged; searching information of thecorresponding document of the ID from a database by using the ID and playing the corresponding document of the ID by using the player; and ending the playing of the document, regenerating the randomnumber which is less than the number range of the document which is not played by the random number generator and ending the playing until all documents are played. The method has the advantages that:1. each document is only played once; and 2, the played sequence is stored by using less memory, thereby having the function of back playing.

Description

【Technical field】 [0001] The invention relates to a data processing method, in particular to a method for realizing random play in a multimedia player. 【Background technique】 [0002] Currently available media players basically have the function of random play, which utilizes a random number generator to generate a random number, searches for the corresponding media file from the file ID list according to the random number, and then plays it through the player, thereby achieving Random play function. However, the above method cannot ensure that all files are only played once in the same cycle, so when the user is playing files, some files will be played multiple times and some will not be played. [0003] In summary, the random play method of the existing media player has the following disadvantages: [0004] 1. The same file will be played repeatedly; [0005] 2. Cannot record the sequence that has been played. [0006] For above-mentioned first kind of shortcoming, Chi...

Problems solved by technology

[0004] 1. The same file will be played repeatedly;

[0005]2. Cannot record the played sequence

[0006] Aiming at the above-mentioned first shortcoming, Chinese invention patent application No. 200510123237.X, titled "Random Play System and Method" discloses a random play method, However, the method of random playback does not have the function of recording the sequence of files that have been played, and the calculation method is very complicated and the running speed is very slow
