VIDEO ENCODING METHOD AND DECODING METHOD USING TILES AND SLICES, AND VIDEO ENCODING DEVICE AND DECODING DEVICE USING TILES AND SLICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17967654 titled 'VIDEO ENCODING METHOD AND DECODING METHOD USING TILES AND SLICES, AND VIDEO ENCODING DEVICE AND DECODING DEVICE USING TILES AND SLICES

Simplified Explanation

The video decoding method described in this patent application involves the following steps:

• Obtaining identification information of a first tile and identification information of a last tile from a bitstream.
• Determining the index difference between the first tile and the last tile by comparing their identification information.
• Using the index difference to determine the number of tiles included in the first slice.
• Decoding a plurality of tiles included in the first slice according to an encoding order, using the number of tiles, the identification information of the first tile, and the identification information of the last tile.

Potential applications of this technology:

• Video streaming services: This method can be used to efficiently decode video streams, improving the quality and speed of video playback on streaming platforms.
• Video conferencing: Implementing this method in video conferencing systems can enhance the decoding process, resulting in better video quality and reduced latency.
• Video surveillance: The method can be utilized in video surveillance systems to decode multiple video streams simultaneously, enabling efficient monitoring of multiple camera feeds.

Problems solved by this technology:

• Efficient decoding: By determining the number of tiles included in a slice and decoding them in the correct order, this method optimizes the decoding process, reducing computational requirements and improving efficiency.
• Seamless video playback: The method ensures smooth video playback by decoding the tiles in the correct order, preventing any disruptions or artifacts in the video stream.

Benefits of this technology:

• Improved video quality: By decoding the tiles in the correct order, this method ensures that the video is reconstructed accurately, resulting in higher quality playback.
• Reduced latency: The optimized decoding process reduces the time required to decode the video, leading to reduced latency in video playback.
• Enhanced efficiency: By determining the number of tiles included in a slice and decoding them efficiently, this method reduces computational requirements, making it more resource-efficient.

Original Abstract Submitted

Provided is a video decoding method including obtaining identification information of a first tile and identification information of a last tile from a bitstream, wherein the first and last tiles are included in a first slice, determining an index difference between the first tile and the last tile, based on a result of comparing the identification information of the first tile with the identification information of the last tile, determining the number of tiles included in the first slice, by using the index difference between the first tile and the last tile, and decoding a plurality of tiles included in the first slice according to an encoding order by using the number of tiles included in the first slice, the identification information of the first tile, and the identification information of the last tile.
