INTER PREDICTION METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18365083 titled 'INTER PREDICTION METHOD AND APPARATUS
Simplified Explanation
The patent application describes methods and apparatuses for inter prediction in video coding. Inter prediction is a technique used in video compression to reduce the amount of data needed to represent a video sequence.
- The method involves constructing a merging candidate list for a current picture block. This list contains potential blocks from previous frames that can be used to predict the current block.
- If the number of merging candidates in the list is less than a certain threshold, at least one history-based motion vector predictor (HMVP) candidate is added to the list. HMVP candidates are based on the motion vectors of previously encoded blocks.
- Motion information of the current picture block is obtained based on the merging candidate list.
- A predicted block of the current picture block is determined using the motion information.
Potential applications of this technology:
- Video compression: This innovation can be used in video coding standards such as H.264, H.265, and AV1 to improve the efficiency of inter prediction, leading to better video compression and reduced bandwidth requirements.
- Video streaming: By reducing the amount of data needed to represent video frames, this technology can improve the quality and speed of video streaming services.
Problems solved by this technology:
- Efficient video compression: Inter prediction is a key technique in video compression, and this innovation improves the accuracy and effectiveness of inter prediction, resulting in better compression ratios and reduced storage and transmission costs.
- Bandwidth optimization: By reducing the amount of data needed to represent video frames, this technology helps optimize bandwidth usage, allowing for smoother video streaming and improved user experience.
Benefits of this technology:
- Improved video quality: By accurately predicting motion information and using it to generate predicted blocks, this technology can enhance the visual quality of compressed videos.
- Reduced bandwidth requirements: By efficiently utilizing motion information and merging candidates, this technology reduces the amount of data needed to represent video frames, resulting in lower bandwidth requirements for video transmission and storage.
Original Abstract Submitted
Methods and apparatuses for inter prediction are disclosed. The method comprises: constructing a merging candidate list of a current picture block; when a number of merging candidates in the merging candidate list is less than a maximum number of candidates minus N, adding at least one history-based motion vector predictor (HMVP) candidate to the merging candidate list to obtain a new merging candidate list, wherein N is a positive integer; obtaining motion information of the current picture block based on the new merging candidate list; and determining a predicted block of the current picture block based on the motion information of the current picture block.
