STORAGE OF INTRA MODE INFORMATION IN GEOMETRIC PARTITION MODE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18526300 titled 'STORAGE OF INTRA MODE INFORMATION IN GEOMETRIC PARTITION MODE

Simplified Explanation

The patent application describes a method for receiving coded information of a current block in a video picture from a coded video bitstream, indicating the block is partitioned into at least two partitions based on a geometric partition mode.

  • The method involves storing prediction mode information for subblocks of the current block, including DC mode, Planar mode, and intra prediction mode.
  • The prediction mode information is based on whether the subblock is associated with an intra block copy prediction mode, intra prediction mode, or both.

Potential Applications

This technology could be applied in video coding and compression algorithms to improve the efficiency of intra prediction modes and block partitioning.

Problems Solved

1. Enhanced video compression by optimizing prediction modes for different block partitions. 2. Improved video quality by accurately predicting pixel values within blocks.

Benefits

1. Higher compression ratios for video data. 2. Better visual quality in compressed videos. 3. Efficient utilization of intra prediction modes.

Potential Commercial Applications

Optimized video compression algorithms for streaming services and video conferencing platforms.

Possible Prior Art

One possible prior art could be the use of different prediction modes in video coding standards like H.264 and H.265 to improve compression efficiency.

Unanswered Questions

How does this method compare to existing video compression techniques in terms of compression ratio and visual quality?

This method could potentially offer higher compression ratios and better visual quality compared to traditional video compression techniques by optimizing prediction modes based on block partitions.

What impact could this technology have on real-time video streaming applications?

This technology could significantly improve the efficiency of real-time video streaming applications by reducing bandwidth requirements while maintaining high visual quality.


Original Abstract Submitted

In a method, coded information of a current block in a current picture of a video is received from a coded video bitstream. The coded information indicates that the current block is partitioned into at least a first partition and a second partition based on a geometric partition mode (GPM). The first partition is associated with an intra block copy (IBC) prediction mode, and the second partition is associated with an intra prediction mode. Prediction mode information for a first subblock of a plurality of subblocks of the current block is stored. The prediction mode information includes one of a DC mode, a Planar mode, and an intra prediction mode based on whether the first subblock is associated with one of the IBC prediction mode, the intra prediction mode, and both the IBC prediction mode and the intra prediction mode.
