System For Adjusting Clock Rate To Avoid Audio Data Overflow And Underrun

View page
US Patent:
6347380, Feb 12, 2002
Filed:
Mar 3, 1999
Appl. No.:
09/261414
Inventors:
Steve Chang - Fremont CA
Jiwen Cai - Cupertino CA
Assignee:
KC Technology, Inc. - Milpitas CA
International Classification:
G06F 104
US Classification:
713503
Abstract:
A phase locked loop is employed to provide a clock signal for controlling the reading or writing of audio data from or into a memory to avoid memory overflow and underrun. The difference between the write and read pointers is monitored and used for adjusting a divider counter used in the feedback loop of the phase locked loop, by incrementing, decrementing by one or leaving unchanged the value of the counter. The counter is used to divide the output of the phase locked loop to provide a reference signal to the phase locked loop. A reference frequency for reading the audio data may be set close to the writing speed by incrementing or decrementing the reading speed by fine adjustment steps until the reference frequency is reached. After the reference frequency is reached, the reading speed is changed between the reference frequency and a frequency one fine adjustment step away from the reference frequency so that the average reading speed is equal to the writing speed.

Abstract:
Techniques are disclosed that generally relate to content delivery techniques in audio-visual systems. In an audio-visual system, a method of using sensors to incrementally present content elements on a display includes presenting a first content element on the display, receiving first data from a sensor, the first data associated with a first distance. An increment coefficient is identified, and a portion size is determined by reducing the first distance by the increment coefficient. Finally, an unseen portion of a second content element is incrementally added to the display, and a presented portion of the first content element is incrementally removed from the display, the size of the portions added and removed being equal to the determined portion size.
