Google patents video coding that trims extra detail to fit bandwidth limits

This patent describes a method for compressing video frames, such as those from a game, by splitting them into a basic image and a layer of extra detail. The system encodes both parts but cuts the extra detail short if the total file size gets too large, ensuring the video fits within a specific data limit before sending it to your device.

Why it mattersThis technique helps streaming services deliver smooth video on slower internet connections by intelligently reducing file size without dropping the entire stream.

In the filing’s own words

An encoding operation is implemented to encode one or more frames, for example, gaming frames into a gaming stream. The encoding operation includes decomposing a current frame into a base layer and an enhancement layer. The resulting base layer and enhancement layer are then each encoded to produce an encoded base layer and an encoded enhancement layer. The encoded enhancement layer is truncated, for example, according to a comparison of the sum of the size of the encoded base layer and encoded enhancement layer to a threshold value. In an example embodiment, a multiplexer combines the encoded base layer and truncated enhancement layer to produce the encoded frame. The encoded frame may then be transmitted as part of a stream to a client device.

What exactly they claim (claim 1)

1. A method, comprising: decomposing a first frame into a base layer of the first frame and an enhancement layer of the first frame; encoding the base layer at a target base layer bitrate based on a target bitrate to produce an encoded base layer; generating a progressive stream from the enhancement layer; truncating the progressive stream based on the target bitrate to produce a truncated progressive stream; and combining the encoded base layer with the truncated progressive stream to produce an encoded first frame.
