Abstract
Methods and systems for video encoding, using a variance measure to directly effect efficiencies and optimizations at various stages of video encoding to improve compute cycle, power, heat and bandwidth efficiency and decoded picture quality and decrease the bit length of encoded frames. Download rate and decoding efficiency are also improved as a result of the improvements realized at the encoder.
Claims
exact text as granted — not AI-modified1 . A method of video encoding, comprising:
generating at least one spatial variance measure across groups of pixels of at least one frame of a stream of frames; and encoding said one frame variably, in dependence on said spatial variance measure; whereby computational load is reduced for ones of said frames which have smaller amounts of spatial variance.
