In modern physics, application of a quantity analogous to Coriolis force appears in electrodynamics wherever instantaneous voltages generated in rotating electrical machinery must be calculated relative to the moving reference frame: this compensation is called the Christoffel voltage.
All conventional video coding standards use block type motion estimation coding, which is a kind of inter frame motion compensation prediction used for reducing temporal redundancy.
For a particular temporal up-sampling method, e.g., motion compensation frame interpolation, the optimal down-sampled frame is the one that not only minimizes the difference between the original and the down-sampled frames but also minimizes the difference between the original and the corresponding up-sampled frames.
Moreover, it considers the interpolated frame during motion compensation along with the neighboring frames.
Keller et al. [10] proposed a variational method for both optical flow calculation (motion estimation) and the actual new frame interpolation (motion compensation).
AMD's DTV assets include Xilleon integrated DTV processors and reference designs, NXT receiver ICs, the Theater 300 DTV processor, and a line of panel processors that perform advanced motion compensation, frame rate conversion and scaling.
Based on the assumption of noise mentioned in Signal model of movie section, the variance σ2 can be estimated according to the residual between adjacent frames after motion compensation.
Furthermore, distortion is accumulated over a sequence of successive P frames due to motion compensation, until a new I frame is inserted.
Intra mode compression operates in a frame-by-frame basis while inter mode achieves compression by applying motion estimation and compensation between frames and taking advantage of the temporal correlation between frames.
Once a signal is detected, exact frame boundary detection and compensation for timing offset are performed.
