Live streaming and On Demand video use has exploded on mobile devices in part due to advances in video compression methods. Many popular video applications such as Youtube, Vimeo, Vine, Hulu, Flash Player, Blu-Ray, and Netflix utilize the H.2164 video compression, which allows for high quality, high-speed video streams. However, video playback of this format requires complex decoding methods and thus, significant power consumption. This technology provides an algorithm to reduce interpolations of motion estimations during compression, thus reducing overall computational needs. Through this technology high quality videos can be encoded and decoded at low computational cost, thus reducing mobile device power consumption. As such end users can enjoy movies, viral videos, live broadcasts and etc. on their mobile devices without sacrificing battery life. .
Motion estimation interpolation is the most computationally intensive portion of the video decoding system. This computational cost leads to significant power consumption, a huge drawback for mobile device video playback. This technology reduces the interpolation steps required for motion estimation in video encoding and decoding.
A prototype of the technology has been tested and shown to reduce computational interpolations by 60% with little loss in video quality (less than 0.2 dB).
