1. A decoding method applied to a multimedia playing system for decoding a multimedia data stream having a plurality of data segments, each of the data segments comprising a plurality of data sub-segments, comprising:
- providing a plurality of first tags respectively corresponding to the data segments, and providing a plurality of second tags respectively corresponding to data sub-segments of an initial data segment among the data segments;
positioning the data segments according to the first tags, positioning the data sub-segments of each of the data segments according to the second tags, and accordingly processing the data sub-segments of each of the of data segments, respectively; and
decoding the processed data sub-segments of each of the data segments to generate a plurality of multimedia sub-segments according to the second tags,wherein the first tags and second tags are inserted in the multimedia data stream according to transmission and multiplexing configuration control (TMCC) information contained in the multimedia data stream.

Abstract
By inserting a symbol start tag at a start of a data segment corresponding to each symbol of a multimedia data stream, and by inserting frame start tags at starts of different frames in a start data segment, data signals belonging to different channels can be precisely and rapidly classified and decoded when the multimedia data stream is performed with demodulation.
