Systems and methods for player input motion compensation by anticipating motion vectors and/or caching repetitive motion vectors

摘要

Systems and methods for reducing latency through motion estimation and compensation incorporate a client device that uses lookup tables from a remote server to match, tag, and sum motion vectors. When a remote server transmits encoded video frames to the client, the client decodes them and applies the summed motion vectors to estimate motion. The technology also generate motion vectors based on predetermined criteria and transmit them and invalidators to a client, which caches them. The server instructs the client to receive input and use it to match to cached motion vectors or invalidators. The technology also caches repetitive motion vectors and transmits previously generated motion vector libraries to a client. The server instructs the client to calculate a motion estimate and instructs the client to update the stored motion vector library, so that the client applies the stored library to initiate motion prior to receiving actual motion vector data.
