Adaptive Video Transmission Using Residue Octree Cubes

Abstract

This paper proposes a method of transmitting video streaming data based on downsampling-upsampling pyramidal decomposition. By implementing an octal tree decomposition of the frame cubes, prior to transforming them into hypercubes, the algorithm manages to increase the granularity of the transmitted data. In this sense, the communication relies on a series of smaller hypercubes, as opposed to a single hypercube containing the entire, undivided frames form a sequence. This translates into increased adaptability to the variations of the transmitting channel’s bandwidth.
