Patent attributes
Aspects of the invention may include gradually decrementing or incrementing a write pointer (370) associated with a data buffer such as the FIFO buffer (310) until a reset value of the write pointer (370) is reached in response to an indication that a data buffer controlled by the gray code counter is empty. Additionally, a read pointer (380) associated with the data buffer (310) may be gradually incremented or decremented until a reset value of the read pointer (380) is reached in response to an indication that the data buffer controlled by the gray code counter is full. The data buffer may be a first-in-first-out (FIFO) buffer such as FIFO buffer 310, which may be asynchronously clocked. The data buffer may be adapted to buffer any one or a combination of video, voice and data.
