Samsung patents video compression tweak for faster encoding
Samsung describes a method for compressing video files by splitting frames into smaller sections called coding tree units. The process uses two steps of mathematical adjustments, known as low complexity rate-distortion optimization, to choose the most efficient way to represent each section before creating the final data stream.
In the filing’s own words
A method of encoding a video includes: partitioning an image frame into a coding tree unit; determining prediction mode candidates for the coding tree unit by applying a first low complexity rate-distortion optimization (LC-RDO), the first LC-RDO including applying a first correction value to correct at least one of a rate, a distortion, and a rate-distortion cost; determining a prediction mode among the prediction mode candidates by applying a second LC-RDO, the second LC-RDO including applying a second correction value to correct the at least one of the rate, the distortion, or the rate-distortion cost; and generating a bitstream based on the determined prediction mode.
What exactly they claim (claim 1)
1. A method of encoding a video, the method comprising: partitioning an image frame into a coding tree unit; determining prediction mode candidates for the coding tree unit by applying a first low complexity rate-distortion optimization (LC-RDO), the first LC-RDO comprising applying a first correction value to correct at least one of a rate, a distortion, or a rate-distortion cost; determining a prediction mode among the prediction mode candidates by applying a second LC-RDO, the second LC-RDO comprising applying a second correction value to correct the at least one of the rate, the distortion, or the rate-distortion cost; and generating a bitstream based on the prediction mode.
