System and method for video encoding using constructed reference frame

An apparatus comprising:

• a memory including instructions for decoding an encoded video stream;
• and
• a processor that executes the instructions to:
• generate a reconstructed video, wherein to generate the reconstructed video the processor executes the instructions to:
• receive an encoded video stream;
• generate a non-showable reconstructed reference frame, wherein to generate the non-showable reconstructed reference frame the processor executes the instructions to decode an encoded frame from the encoded video stream;
• generate a reconstructed frame, wherein to generate the reconstructed frame the processor executes the instructions to decode a second encoded frame from the encoded video stream using the non-showable reconstructed reference frame as a reference frame;
• and
• include the reconstructed frame in the reconstructed video;
• and
• output the reconstructed video, wherein the reconstructed video omits the non-showable reconstructed reference frame.

A method of decoding an encoded bitstream, the method comprising:

• generating, by a processor in response to instructions stored on a non-transitory computer readable medium, a reconstructed video, wherein generating the reconstructed video includes:
• receiving an encoded bitstream;
• generating a reconstructed non-showable reference frame, wherein generating the reconstructed non-showable reference frame includes decoding a first encoded frame from the encoded bitstream;
• generating a reconstructed frame, wherein generating the reconstructed frame includes decoding a second encoded frame from the encoded bitstream using the reconstructed non-showable reference frame as a reference frame;
• and
• including the reconstructed frame in the reconstructed video;
• and
• outputting the reconstructed video.
