IMAGE/VIDEO ENCODING/DECODING METHOD AND DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17780812 titled 'IMAGE/VIDEO ENCODING/DECODING METHOD AND DEVICE
Simplified Explanation
The video decoding method described in this patent application involves parsing information from a bitstream to determine the number of slices and their heights in a tile of a current picture. The method then derives the heights of each slice and decodes the current picture based on these slices.
- The method parses number information from a bitstream to determine the number of slices and their heights in a tile.
- It then parses height information to determine the heights of each slice.
- The method derives the heights of the slices in the tile based on the parsed information.
- It decodes the current picture based on the derived slices.
Potential applications of this technology:
- Video streaming services: This method can be used in video decoding devices to improve the decoding process, resulting in better video quality and smoother streaming experience.
- Video surveillance systems: The method can enhance the decoding capabilities of video surveillance devices, allowing for more efficient processing of video data.
Problems solved by this technology:
- Efficient decoding: By parsing and deriving slice heights, this method optimizes the decoding process, reducing computational complexity and improving overall efficiency.
- Accurate decoding: The method ensures that each slice is decoded correctly by deriving their heights accurately, resulting in a more accurate representation of the original video.
Benefits of this technology:
- Improved video quality: By accurately decoding each slice, this method can enhance the overall video quality, reducing artifacts and improving clarity.
- Efficient processing: The method's optimized decoding process reduces computational complexity, allowing for faster and more efficient video decoding.
- Enhanced user experience: By improving video quality and decoding efficiency, this technology can provide users with a better streaming or surveillance experience.
Original Abstract Submitted
A video decoding method performed by a video decoding device according to the present document may comprise the steps of: parsing, from a bitstream, number information relating to the number of slices each having an explicitly signaled height in a tile of a current picture; on the basis of the number information, parsing, from the bitstream, height information relating to heights of the slices each having an explicitly signaled height; when a value of the number information is n, deriving heights of 0-th to (n−1)-th slices in the tile on the basis of the height information; deriving the height of the n-th slice in the tile on the basis of the height of the (n−1)-th slice; deriving a height of a last slice in the tile on the basis of a height remaining after subtracting the sum of heights of the other slices in the tile from a height of the tile; deriving the number of slices in the tile; and decoding the current picture on the basis of slices of the current picture.
