Video codec data recovery techniques for lossy wireless links

摘要

Systems, apparatuses, and methods for implementing data recovery techniques for lossy wireless links are disclosed. A transmitter is configured to encode a video stream and wirelessly transmit the encoded video stream to a receiver, with the video stream representing a virtual reality (VR) rendered environment. The transmitter partitions the video stream into a plurality of substream components based on frequency. Motion vector parameters are calculated for the lowest frequency substream component of the video stream only, and the motion vector parameters are sent to the receiver using a low MCS level. When the receiver receives the motion vector parameters, but the receiver does not receive the lowest frequency component of a given chunk, the receiver uses the motion vector parameters to reconstruct the lowest frequency component of the given chunk by extrapolating from a corresponding chunk of the previous video frame.
