==VIDEO ENCODING DEVICE, VIDEO DECODING DEVICE, VIDEO ENCODING METHOD, VIDEO DECODING METHOD, AND VIDEO SYSTEM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18284373 titled 'VIDEO ENCODING DEVICE, VIDEO DECODING DEVICE, VIDEO ENCODING METHOD, VIDEO DECODING METHOD, AND VIDEO SYSTEM

==Simplified Explanation==

The video encoding device described in the abstract utilizes a predictor that performs prediction processes using intra-prediction or inter-prediction, along with a coding controller that ensures certain conditions are met during the coding process. Specifically, the predictor selects the closest picture in the display order as a reference picture when coding a picture that refers to a picture in a lower layer.

* Predictor performs prediction processes using intra-prediction or inter-prediction.
* Coding controller ensures that pictures in later display orders are not coded before pictures in earlier display orders.
* Coding controller also ensures that pictures in lower layers do not refer to pictures in upper layers.
* Predictor selects the closest picture in the display order as a reference picture when coding a picture referring to a picture in a lower layer.

== Potential Applications ==
The technology described in this patent application could be applied in various video encoding devices and systems where efficient coding and prediction processes are crucial.

== Problems Solved ==
1. Ensures proper coding order of pictures in video encoding.
2. Prevents referencing of pictures in upper layers by pictures in lower layers.

== Benefits ==
1. Improved video encoding efficiency.
2. Enhanced video quality through optimized prediction processes.

== Potential Commercial Applications ==
Optimized video encoding devices for broadcasting, streaming, surveillance systems, and video conferencing applications.

== Possible Prior Art ==
Prior art may include existing video encoding technologies that utilize prediction processes but may not specifically address the coding order of pictures in relation to display order.

== Unanswered Questions ==
=== How does this technology compare to existing video encoding devices in terms of coding efficiency? ===
The article does not provide a direct comparison with existing video encoding devices in terms of coding efficiency.

=== What impact does this technology have on overall video quality? ===
The article does not explicitly mention the impact of this technology on overall video quality.


==Original Abstract Submitted==

The video encoding device includes a predictor which performs a prediction process using intra-prediction or inter-prediction, and a coding controller which controls the predictor so that under a predetermined condition that pictures in the later display order are not coded before pictures in the earlier display order and that pictures in lower layers do not refer to pictures in upper layers, the predictor uses a picture closest in the display order to a picture to be coded as a reference picture when coding the picture referring to a picture in the lower layer.
