==Intra-Frame Prediction and Decoding Methods and Apparatuses for Image Signal - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18536562 titled 'Intra-Frame Prediction and Decoding Methods and Apparatuses for Image Signal

The abstract of this patent application describes an intra-frame decoding method for video streams that involves obtaining prediction mode information for a signal component of a block, determining the prediction mode of the signal component, obtaining a predicted value for a sampling point of the signal component, and obtaining a reconstructed value for the sampling point based on the predicted value.

* Prediction mode information is obtained for a signal component of a block from a video code stream.
* The prediction mode of the signal component is determined from a set that includes linear model above (LMA) and linear model left (LML) modes.
* A predicted value for a sampling point of the signal component is obtained.
* A reconstructed value for the sampling point is obtained based on the predicted value.

==Original Abstract Submitted==

An intra-frame decoding method includes obtaining, from a video code stream, prediction mode information of a first signal component of a current block; determining a prediction mode of the first signal component of the current block from a prediction mode set of the first signal component of the current block according to the prediction mode information of the first signal component of the current block, where the prediction mode set of the first signal component of the current block includes at least one of a linear model above (LMA) mode and a linear model left (LML) mode; obtaining a predicted value of a first signal component sampling point of the current block; and obtaining a reconstructed value of the first signal component sampling point of the current block according to the predicted value of the first signal component sampling point of the current block.
