Patent number: 6967599Abstract: Audio data decoded in an MPEG system to be stored in a storage unit is supplied to an audio output via a filtering processing. For performing the filtering processing, presentation time interval of respective audio data is changed to conform to a user's designated playback speed, and the decoded audio data stored in the storage unit by being synchronized with the changed presentation time interval is written on an input queue in the set unit. A TSM algorithm is performed in the frame unit with respect to the audio data of the input queue to decrease the quantity of the audio data when the designated playback speed is faster than a normal playback speed or to increase it when the designated playback speed is slower than the normal playback speed, in accordance with a value of the designated playback speed. The TSM audio data is transferred to a middle queue.Type: GrantFiled: May 30, 2001Date of Patent: November 22, 2005Assignee: Cosmotan Inc.Inventors: Won-Yong Choi, Byoung-Chul Lee, Sang-Hun Jeong, Won-Sik Choi
