Picture Prediction Method and Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 18168799 titled 'Picture Prediction Method and Apparatus
Simplified Explanation
The patent application describes a method for predicting pictures in a video compression system. Here is a simplified explanation of the abstract:
- The method starts by receiving a bitstream, which contains encoded video data.
- The bitstream is parsed to determine the prediction mode of a current block in the video.
- If the prediction mode is a combined intra and inter prediction mode, the method selects an execution manner for a triangular prediction unit mode based on a preset policy.
- Motion information of the current block is then determined according to the selected execution manner.
- A motion compensation process is performed using the motion information to obtain an inter prediction sample.
- An intra prediction sample is obtained based on the prediction mode of the current block.
- Finally, the inter prediction sample and the intra prediction sample are combined to obtain a prediction picture for the current block.
Potential applications of this technology:
- Video compression: The method can be used in video compression systems to improve the efficiency of encoding and decoding video data.
- Video streaming: By using efficient prediction methods, video streaming services can deliver high-quality video content with reduced bandwidth requirements.
- Video conferencing: The method can be applied in video conferencing systems to enhance the quality of real-time video communication.
Problems solved by this technology:
- Efficient video compression: The method improves the compression efficiency by utilizing both intra and inter prediction modes.
- Enhanced video quality: By combining inter and intra prediction samples, the method can produce more accurate predictions, resulting in higher-quality video.
- Bandwidth optimization: The method helps reduce the amount of data needed to transmit video, making it suitable for applications with limited bandwidth.
Benefits of this technology:
- Improved compression efficiency: By selecting the appropriate execution manner and combining prediction samples, the method can achieve better compression ratios.
- Enhanced video coding performance: The method improves the accuracy of motion compensation, leading to higher-quality video coding.
- Reduced bandwidth requirements: By optimizing the prediction process, the method helps reduce the amount of data needed to transmit video, resulting in bandwidth savings.
