By providing a setting for generating a playlist, the method for media playing in the portable device has more selectivity and greater flexibility to meet user needs.

Description

Media playing method of portable device and its portable device

technical field

The present invention relates to a playing method and a portable device using the playing method to play media, especially a directory-based media playing method and the related portable device.

Background technique

For portable devices such as mobile phones, mobile walkmans, personal digital assistants, and mobile multimedia devices, it is the current mainstream product trend to demand multimedia playback to provide consumers with diverse and free-wheeling experience. The support for the types of multimedia that can be played is also increasing. As far as the user uses a portable device to play multimedia files (such as music files in MP3 format), a general MP3 player plays files based on a playlist that includes one or more media file messages.

There are usually several ways to generate a playlist:

1. Use the information of each field of ID3 embedded in the media file to create a playlist. Users can make selections based on existing classifications (such as album titles, performers, release years, music genres, etc.), while portable devices will select multiple media with the same attribute according to the user's selection. The data of the file is created as a playlist for playback. However, the ID3 field information embedded in these media files must be pre-established when the media file is created (or before the media file is searched in the device), or the media to be searched must be first set when the portable device is powered on or off. The database is built.

2. The list generation method based on the disk directory. Create a list with the file directory system commonly used at present, and the generation method of such a list is that after the user selects a media file in the portable device, all the media files in the entire portable device are directly created into a global media play list , and start playing the entire global playlist at the media file selected by the user. This approach lacks the flexibility of media selection, because the user can only use one way to generate the list.

3. The user creates a list of playlists in advance. Before the portable device plays the media files, the user selects different media files one by one according to personal preferences to create a playlist. The content of the playlist includes media files selected by the user and a sequence defined by the user. Although this approach can provide users with a high degree of flexibility in customization, it also means that users must spend a lot of effort to create playlists in advance, and once such playlists are created, it is not easy to modify them flexibly, which also limits It is convenient to use in some occasions.
