Abstract:
Real-time, hardware-implementable Structured Similarity (SSIM)-based rate distortion optimization (RDO) techniques for video transmission are described. The disclosed techniques provide efficient application of SSIM as a distortion metric in selecting prediction modes for encoding video for transmission. A prediction mode, at a high level, specifies which previously encoded group of pixels can be utilized to encode a subsequent block of pixels in a video frame. A less compute intensive distortion metric is first used to select a subset of candidate prediction modes. Then a more compute intensive SSIM-based selection is made on the subset. By utilizing the disclosed techniques during video encoding, tradeoffs between distortion and transmission rate can be made that are more relevant to human perception.

Claim (Index 22):
A video decoder comprising:\n a video receiver that decodes a video stream including a block of pixels encoded using a prediction mode from an identified set of prediction modes compatible for decoding, the block of pixels being encoded by a video encoder that calculates distortion of the block by the set of prediction modes compatible for decoding, selects, based on the calculated distortion, a subset of the set of prediction modes, uses structured similarity (SSIM) distortion estimation to calculate distortion of the block of pixels for each prediction mode in the selected subset, and identifies one of the prediction modes in the subset for use in encoding the block based on the estimation and bit rates for encoding the block; and at least one of a decode capability identifier that identifies to the video encoder the set of prediction modes compatible for decoding, and a prediction-dependent configurator that changes a configuration in the video decoder in response to receiving an indication of the SSIM distortion estimation from the video encoder.
