ENCODING METHOD AND DEVICE THEREOF, AND DECODING METHOD AND DEVICE THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18165126 titled 'ENCODING METHOD AND DEVICE THEREOF, AND DECODING METHOD AND DEVICE THEREOF
Simplified Explanation
The video decoding method described in the patent application involves several steps to decode a video block:
- Determine if the ultimate motion vector expression (UMVE) mode is allowed for the upper data unit that includes the current block.
- If UMVE mode is allowed, determine if it should be applied to the current block.
- If UMVE mode is applied, determine a base motion vector for the current block.
- Determine a correction distance and direction to correct the base motion vector.
- Calculate the motion vector of the current block by correcting the base motion vector using the correction distance and direction.
- Reconstruct the current block based on the calculated motion vector.
Potential applications of this technology:
- Video decoding in various multimedia applications.
- Video streaming services.
- Video conferencing and telecommunication systems.
- Video surveillance and security systems.
Problems solved by this technology:
- Efficient decoding of video blocks by utilizing the UMVE mode.
- Improved accuracy in determining motion vectors for video blocks.
- Enhanced video quality and reduced artifacts in reconstructed video frames.
Benefits of this technology:
- Higher video compression efficiency.
- Reduced bandwidth requirements for video transmission.
- Improved video quality and smoother playback.
- Enhanced user experience in video applications.
Original Abstract Submitted
A video decoding method includes determining whether an ultimate motion vector expression (UMVE) mode is allowed for an upper data unit including a current block, when the UMVE mode is allowed for the upper data unit, determining whether the UMVE mode is applied to the current block, when the UMVE mode is applied to the current block, determining a base motion vector of the current block, determining a correction distance and a correction direction for correction of the base motion vector, determining a motion vector of the current block by correcting the base motion vector according to the correction distance and the correction direction, and reconstructing the current block based on the motion vector of the current block.
