  • Patent number: 7830754
    Abstract: A method for playing a fast rolling music disc is provided. A music disc is read at an accelerated rate and played at a standard rate by discretely buffering data blocks into a ping pong buffer. Playing of a first data block stored in the first buffer, and buffering of a second data block into the second buffer are concurrently executed. When the playing of the first data block is concluded, the playing order of the first buffer and the second buffer are interchanged, and the concurrent playing and buffering step is repeated. Such that the second data block is played in the second buffer while a third data block is buffered into the first buffer. Discreteness between the second data block and the first data block is dependent on a skipping ratio, and the skipping ratio is dependent on the accelerated rate.
