Multimedia stream buffer and output method and multimedia stream buffer module

A multimedia stream buffer module, comprising:

• a first buffer, for storing a plurality of multimedia stream packets, the first buffer corresponding to a buffer time, and the first buffer being divided into a plurality of buffer units according to a time unit;
• a controller, used for performing following steps:
• receiving the multimedia stream packets and storing the multimedia stream packets into the first buffer;
• calculating an actual remaining time according to an accumulated idle time and the buffer time;
• and
• when the actual remaining time is greater than a remaining time threshold value, performing following steps:
• reading a first present time and executing a sleep instruction, so as to wait for a preset idle time;
• reading a second present time, and calculating an actual idle time according to the first present time and the second present time, the actual idle time being different from the preset idle time;
• accumulating the accumulated idle time according to the actual idle time;
• and
• enabling a part of the buffer units according to the accumulated idle time to output the stored multimedia stream packets to a second buffer of a player.
