Embodiment 1

[0037] A user's multimedia mobile phone is externally connected with a memory card with a storage capacity of 8Gbyte, and the identification path of the memory card in the mobile phone system is "SDmemory:\". The multimedia mobile phone applies the method of the present invention, and a folder named "Music" will be generated in advance under the identification path of the memory card "SDmemory:\", and a folder named "Streaming Media" will be generated under the "Music" folder. subfolder, and use the storage area of ​​the subfolder "Streaming Media" as the multimedia mobile phone's buffer area for streaming media audio files, so the identification path of the buffer area in the mobile phone system is "SDmemory:\Music\Streaming Media" . When the user surfs the Internet with a multimedia mobile phone and links to an online music website with the domain name "http: / / wap.yinyue.com" to play music online, the processing flow of the mobile phone is as follows:

[0038] 1) The mobile...

Embodiment 2

[0043] Another solution of the present invention further improves the steps of the method described in Embodiment 1. Still taking the example of an online multimedia mobile phone with a memory card "SDmemory:\" connected to the user to play music on the Internet in Embodiment 1, illustrate The streaming media audio file playing method of this improvement plan; Concrete steps are as follows:

[0044] 1) The mobile phone first presets the cache area under the memory card identification path, that is, "SDmemory:\Music\Streaming Media"; at the same time, formulate a cache information table, the cache information table is composed of cache record items, and the cache record items include at least There are link address column, cache path column, total data record column, cache record column and storage identification column, which are respectively used to record the link address and total data value of streaming media audio files. 总 , cached data volume value D and preservation ide...

Abstract

The invention provides a streaming media audio file play method based on a mobile terminal memory card cache technology, in the method, a predetermined storage region in a memory card externally connected with the mobile terminal is used as a cache region specially used for caching the streaming media audio file, so that one or more integral streaming media audio files can be stored in the cache region, users can repeatedly listen to the audio files only by reading the cached files again without downloading from a streaming media server, time and data communication cost are saved for the users, and the cache occupies no memory capacity of a mobile terminal processor and has no influence on system processing capability of the mobile terminal; simultaneously, a technical means of the mobileterminal external memory card is mature and used widely, technicians of the field can easily set the cache region in the memory card, and maneuverability is very strong.

Description

technical field [0001] The invention relates to the fields of data processing technology and mobile communication technology, in particular to a streaming media audio file playback method based on mobile terminal memory card buffering technology.
