Abstract:
An encoding acceleration method of cloud VR (virtual reality) video, the method comprising: constructing a reference frame candidate for encoding of a current frame; selecting a specific reference frame among the reference frame candidate based on a sensor data of IMU (Inertial Measurement Unit); selecting a prediction mode for encoding the current frame based on information included in the specific reference frame; and encoding the current frame based on the selected prediction mode.
