METHOD AND APPARATUS FOR DECODING VIDEO, AND METHOD AND APPARATUS FOR ENCODING VIDEO - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240107059 titled 'METHOD AND APPARATUS FOR DECODING VIDEO, AND METHOD AND APPARATUS FOR ENCODING VIDEO
Simplified Explanation
The patent application describes a video decoding method and apparatus that determine the availability of a motion vector of an adjacent block at a specific resolution. If the motion vector of the adjacent block is available, it is used as a predictor for the current block. If not available, a default motion vector from one of the two other adjacent blocks is used for prediction on the current block.
- Motion vector resolution determination:
- The method checks if the motion vector of an adjacent block at a specific resolution is available. - If available, it is used as a predictor for the current block. - If unavailable, a default motion vector from another adjacent block is used for prediction.
- Motion vector prediction:
- Utilizes available motion vectors for accurate prediction. - Enhances video decoding efficiency by utilizing neighboring block information effectively.
Potential Applications
The technology can be applied in video encoding and decoding systems, multimedia streaming services, video conferencing applications, and digital video processing tools.
Problems Solved

One potential prior art could be the use of neighboring block information for motion vector prediction in video encoding and decoding processes. However, the specific method described in this patent application may offer improvements in efficiency and accuracy compared to existing techniques.
Unanswered Questions
How does this technology impact video streaming services?
This technology can potentially improve video quality and reduce bandwidth requirements for video streaming services, leading to a better user experience and cost savings for service providers.
What are the implications of using default motion vectors in video decoding?
Using default motion vectors when adjacent block information is unavailable may impact the accuracy of motion vector prediction and overall video quality. Further research may be needed to optimize the selection and utilization of default motion vectors in such scenarios.
Original Abstract Submitted
in a video encoding and decoding process, a video decoding method and a video decoding apparatus are provided to for determining whether a motion vector of an adjacent block at a location corresponding to one motion vector resolution among a plurality of motion vector resolutions is available, when the motion vector of the adjacent block is available, obtaining the motion vector of the adjacent block as a motion vector predictor of a current block, when the motion vector of the adjacent block is unavailable, obtaining a default motion vector by using a motion vector of one of two other adjacent blocks of the current block as a motion vector predictor of the current block, and performing prediction on the current block based on the motion vector predictor of the current block.
