TEMPORAL CONSISTENCY AND COMPRESSION EFFICIENCY IN VIDEO STREAMING

Original (Chinese)

Systems and method for improving video streaming efficiency are provided. An example method includes receiving encoded frames of a media content item comprising a sequence of encoded grayscale frames and an encoded reference frame, wherein each encoded grayscale frame comprises a luminance parameter normalized to a luminance parameter of the encoded reference frame. The method also includes receiving metadata comprising color transfer instructions, and decoding the received frames to obtain a sequence of decoded grayscale frames and a decoded reference frame. The method then includes determining, for each decoded grayscale frame, a color transfer based on: (i) the color transfer instructions, and (ii) the decoded reference frame, and applying the color transfer to each decoded frame to obtain a sequence of decoded color frames.
