Video transmission system with color prediction and method of operation thereof

摘要

A video transmission system and the method of operation thereof includes: a base layer encoder unit encodes a first video frame for generating a first encoded video frame and a color reference frame including dynamically partitioning the color space of the first video frame; an enhancement layer encoding unit for generating a subsequent encoded video frame by differentially encoding a resampled color frame reference and a subsequent video frame; a video stream transport accessed by a bit stream multiplex unit for multiplexing the first encoded video frame and the subsequent encoded video frame; a reference capture unit to generate a decoded video stream by capturing the resampled color frame reference, for decoding the video stream transport, by applying the subsequent encoded video frame to the resampled color frame reference; and a display, coupled to the reference capture unit and the decoded video stream from the video stream transport, for displaying the decoded video stream.

1. A method of operation of a video transmission system comprising:
encoding a first video frame for generating a first encoded video frame and a color reference frame including dynamically partitioning a color space of the first video frame; generating a subsequent encoded video frame by differentially encoding a resampled color frame reference, from the color reference frame, and a subsequent video frame; accessing a video stream transport by multiplexing the first encoded video frame and the subsequent encoded video frame; generating a decoded video stream by capturing the resampled color frame reference, for decoding the video stream transport, by applying the subsequent encoded video frame to the resampled color frame reference; presenting on a display the decoded video stream from the video stream transport; and analyzing a partition of the color space of the first video frame for determining a Cb partition based on an average value of a Chroma Cb range of the first video frame, wherein the color space can include two or more of the partitions.
