ABSTRACT:
Methods and systems for processing pixels within a decoded video stream are disclosed. Processed pixels may be received within the decoded video stream and may be buffered in a buffer at a first rate. The buffered received processed pixels may be transferred out of the buffer at a second rate, where the first rate is greater than said second rate. The buffering of the received processed pixels and the transferring of the buffered received processed pixels out of the buffer may be monitored to prevent an overrun of the buffer. The first rate of the buffering of the received processed pixels may be reduced to prevent the overrun of the buffer. The second rate of the transferring of the buffered received processed pixels out of the buffer may be monitored to prevent the overrun of the buffer. Amount of the buffered received processed pixels within the buffer may be determined.
