Title:
ADAPTIVELY ENCODING VIDEO FRAMES USING CONTENT AND NETWORK ANALYSIS
Document Type and Number:
WIPO Patent Application WO/2021/092821
Kind Code:
A1
Abstract:
An example apparatus for adaptively encoding video frames includes a network analyzer to predict an instant bitrate based on channel throughput feedback received from a network. The apparatus also includes a content analyzer to generate ladder info based on a received frame. The apparatus further includes an adaptive decision executer to determine a frame rate, a video resolution, and a target frame size based on the predicted instant bitrate and the ladder outputs. The apparatus further includes an encoder to encode the frame based on the frame rate, the video resolution, and the target frame size.
