==VIDEO CODING DEVICE AND VIDEO CODING METHOD - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240107009 titled 'VIDEO CODING DEVICE AND VIDEO CODING METHOD

==Simplified Explanation==

The patent application describes a video coding device that optimizes prediction mode selection by calculating energy values of prediction error signals and transform coefficients, and making decisions based on these values.

* The device calculates the energy of prediction error signals for the block to be processed.
* It eliminates specified transform coefficients if the block size exceeds a predetermined value.
* The device then calculates the energy of the remaining transform coefficients.
* If the energy of the remaining coefficients is significantly smaller than the energy of the prediction error signals, the device decides not to select the candidate prediction mode as the optimal mode.

== Potential Applications ==
This technology can be applied in video coding and compression algorithms to improve efficiency and reduce data size.

== Problems Solved ==
1. Improved prediction mode selection in video coding.

==Original Abstract Submitted==

the video coding device calculates a first value representing energy of the prediction error signals of the block to be processed, eliminates specified transform coefficients when at least one of a width and a height of the block to be processed exceeds a predetermined value and calculates a second value representing energy of the transform coefficients other than the eliminated transform coefficients, and decides not to make the candidate of prediction mode the optimal prediction mode, without executing quantizing, arithmetic-coding and local decoding, in a case where the second value is smaller than a predetermined degree as compared to the first value.
