Google patents video compression method for managing reference frames
This filing describes a method for decoding video by using a specific number to identify where to store a decoded frame in a temporary memory area. The stored frame is then used as a reference to help decode subsequent frames in the video stream.
In the filing’s own words
An integer value indicative of a slot of a reference frame buffer to be updated is decoded from a compressed bitstream. A first frame is decoded. The decoded first frame is added to the slot indicated by the integer value. The decoded first frame is used, from the reference frame buffer, as a reference frame for decoding a second frame.
What exactly they claim (claim 1)
1. A method, comprising: decoding, from a compressed bitstream, an integer value indicative of a slot of a reference frame buffer to be updated; decoding a first frame; adding the decoded first frame to the slot indicated by the integer value; and using the decoded first frame, from the reference frame buffer, as a reference frame for decoding a second frame.
