SIGN PREDICTION FOR MULTIPLE COLOR COMPONENTS IN VIDEO CODING - A simplified explanation of the abstract

• This abstract for appeared for patent application number 18335757 Titled 'SIGN PREDICTION FOR MULTIPLE COLOR COMPONENTS IN VIDEO CODING'

Simplified Explanation

This abstract describes a method for predicting the sign of coefficients in a joint residual block of video data. The method uses color components and joint coding of chroma residuals to generate coefficients for individual residual blocks. These coefficients are then used to reconstruct the original video data.

Original Abstract Submitted

An example method includes predicting, based on a plurality of color components of a block of video data coded using joint coding of chroma residuals (JCCR), a sign of a coefficient of a plurality of coefficients of a joint residual block of the block of video data; generating, for each respective color component of the plurality of color components and based on the plurality of coefficients of the joint residual block, coefficients of a respective residual block of a plurality of residual blocks; and reconstructing, based on the plurality of residual blocks, the block of video data.
