A system and method for providing video signals wherein the video signals from a single video source may be separately passed over two different transmission paths. Such lubricating compositions have reductions in their friction coefficients that are greater than similar compositions formulated with Group III or PAO base oils. Two mutually inclined planes can be defined, with the one vane being arranged on the one plane or the two vanes being arranged on the two planes. Pursuant to this invention, when a tilting disturbance occurs, and some of it is dissipated in a net axial movement at a different frequency, energy is subtracted out of the system with motion that is not linearly related to the disturbance was that created it. Generation of a second set of features may be based on the second set of compressed components from the current frame and a combination of amplitude andor phase components from the past frame.
