Google patents video compression method using multiple reference frames

This filing describes a way to compress video files by predicting what a section of the current image looks like. Instead of relying on just one previous frame, the system finds matching sections in two different past frames and averages their pixel values to create a more accurate guess.

Why it mattersThis is a technical improvement to how video data is stored and sent, which could help streaming services use less bandwidth without lowering picture quality.

In the filing’s own words

A motion vector for a current block of a current frame is identified. The motion vector refers to a first reference block in a first reference frame. Using motion information associated with the first reference block that refers to a second reference frame, a second reference block in the second reference frame is identified. The first reference block and the second reference block are combined to obtain a prediction block for the current block. Combining the first reference block and the second reference block may include obtaining pixel values of the prediction block by averaging respective co-located pixel values of the first reference block and the second reference block.

What exactly they claim (claim 1)

1. A method, comprising: identifying a motion vector for a current block of a current frame, wherein the motion vector refers to a first reference block in a first reference frame; identifying, using motion information associated with the first reference block that refers to a second reference frame, a second reference block in the second reference frame; and combining the first reference block and the second reference block to obtain a prediction block for the current block.
