Abstract
A video server generates metadata representative of interpolation parameters for portions of a first frame representative of a scene in a stream of frames including the first frame. The interpolation parameters are used to generate at least one interpolated frame representative of the scene subsequent to the first frame and prior to a second frame in the stream of frames. The video server incorporates the metadata into the stream and transmits the stream including the multiplexed metadata. A video client receives the first frame representative the stream of frames including the metadata. The video client generates one or more interpolated frames representative of the scene subsequent to the first frame and prior to a second frame in the stream of frames based on the first frame and the metadata. The video client displays the first frame, the one or more interpolated frames, and the second frame.
