Abstract

A data processing system. A storage medium stores an audio data stream comprising a plurality of samples. A seek unit seeks through the audio data stream to determine a file offset of a target sample. A playback controller controls playback of the audio data stream. The playback controller is assigned an execution priority higher than the seek unit, and the seek unit and the playback controller operates according to their assigned execution priority.

Description

technical field [0001] The invention relates to data processing technology, in particular to a method for searching a target position in a media data stream and a system using the method. Background technique [0002] As far as the playback of media data is concerned, such as audio data (such as MP3 data) and video data (such as MPEG 4 data), the data access time is one of the factors affecting the playback performance, and it is generally called seek time. Search time includes the time spent accessing and analyzing data. [0003] In practice, seek times vary depending on the size and format of the media file. For example, a search process for large media files or media files with variable bit rates consumes considerable processor resources. Usually, the searching program and the playing program are combined to form the searching / playing program, and the execution priority is given to it higher than that of the user interface program. When the search / play program is runni...
