Title:
COMPUTATIONALLY CONSTRAINED VIDEO ENCODING
Document Type and Number:
WIPO Patent Application WO2004004356
Kind Code:
A3
Abstract:
Video encoding techniques are described that involve determining a number of processing cycles used during encoding of a video frame, and encoding the video frame without using motion estimation techniques when a number of processing cycles used during encoding exceeds a threshold. For example, the threshold may define a number of processing cycles available for encoding of the given video frame, and the determined number of processing cycles may be a counted number of cycles used during the encoding process of the given video frame. If the number of processing cycles used during encoding exceeds the threshold, motion estimation techniques can be discontinued in favor of less computationally intensive encoding techniques such as texture encoding.
