Patent number: 9106925Abstract: Compression of a video by segmentation, transformation, transform encoding, difference encoding, and muxing. The segmentation looks at energies of the frames, in order to find three different things: black frames which have energy less than the specified amount, consecutive frames which have energy difference is less than the specified amount, and changes in scene which have energy difference is more than a specified amount. If there is little or no energy or energy difference, then the frame is replaced by an indication rather than information about the frame itself; either an indication of a black frames or an indication of no change between two adjacent frames. If there is much energy, then this is taken as the beginning of a new scene, and used as an area to change group of frames.Type: GrantFiled: January 11, 2011Date of Patent: August 11, 2015Assignee: Ubiquity Holdings, Inc.Inventors: Christopher Carmichael, Connie Jordan, Kristian Sandberg
