Reference choice for the video interpolation or extrapolation

摘要

This disclosure describes the selection of reference video units to be used for interpolation or extrapolation of a video unit, such as video frames. The decoder is capable of applying the quality-focused mode to select a reference frame based on the quality criteria. The quality criteria may indicate a quality level that may be generated by the reference frame. If the reference frame does not meet the quality standards, interpolation or extrapolation is disabled. Interpolated or extrapolated display frame is selectively effective on the basis of quality analysis. The decoder can be applied based on the power and quality considerations, a number of frame interpolation or resource focused frame interpolation mode that the extrapolation valid or invalid frames. In one mode, when there is no possibility that the reference frame to produce a satisfactory quality, frame interpolation in order to save power is disabled. In another mode, it can be adjusted according to the threshold power saving requirements.
