AI Technical Summary

Benefits of technology

The technology allows for efficient coding videos by predicting how many times they are moving around within that specific range or region. This helps with better compression efficiency without sacrificing accuracy when adjusting their resolutions.

Problems solved by technology

This patented describes how traditional image processing techniques use different ways to compress images efficiently without sacrificing quality or increasing their size due to redundancy introduced during transmission over communication networks. Specifically, there can exist issues where older coding standards have limited ability to effectively encode high-quality videos while maintaining low bit depth levels that could result in poorer visual perception when displayed together compared to new formats like H264. Additionally, even if these improvements were made they still resulted in increased computational complexity because each pixel needs its own set of parameters to decode separately.

Abstract

The present disclosure relates to a method and apparatus for improving the encoding efficiency by adaptively changing the resolution of the motion vector in the inter prediction encoding and inter prediction decoding of a video. The apparatus includes: a predicted motion vector calculator for calculating a predicted motion vector of a current block to be encoded using motion vectors of one or more surrounding blocks; and a skip mode encoder for encoding a result of performing a prediction of the current block and information indicating that the current block is a skip block when the predicted motion vector satisfies a skip condition, wherein at least one motion vector among the motion vectors of the surrounding blocks and the motion vector of the current block has a resolution different from resolutions of the other motion vectors.
