ABSTRACT:
This disclosure is directed to encoding techniques that can be used to improve encoding of digital video data. The techniques can be implemented by an encoder of a digital video device in order to reduce the number of computations and possibly reduce power consumption during video encoding. More specifically, video encoding techniques are describe which utilize one or more programmable thresholds in order to terminate the execution of various computations when the computations would be unlikely to improve the encoding. By terminating computations prematurely, the amount of processing required for video encoding can be reduced, and power can be conserved.
