Palette Mode Coding With Designated Bit Depth Precision - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240305802 titled 'Palette Mode Coding With Designated Bit Depth Precision

Simplified Explanation: The patent application describes a method for designating bit depth precision for palette mode coding of video blocks by writing syntax elements to a bitstream. These syntax elements include information about the bit depth used for palette mode coding and whether to apply a bit offset.

The patent application focuses on encoding a prediction residual for a video block along with syntax elements indicating the bit depth used for palette mode coding.
During decoding, the values of the syntax elements are read from the bitstream to determine the bit depth for palette mode coding the encoded block.

Key Features and Innovation:

Syntax elements are written to a bitstream to designate bit depth precision for palette mode coding of video blocks.
The method allows for dynamic selection of the bit depth to use for palette mode coding based on input video signals or changes in bit depth precision.
Syntax elements include information on the palette mode coding bit depth used and whether to apply a bit offset.

Potential Applications: The technology can be applied in video encoding and decoding systems, particularly in scenarios where palette mode coding is utilized for efficient compression.

Original Abstract Submitted

syntax elements are written to a bitstream to designate bit depth precision for palette mode coding of video blocks. during encoding, a bit depth to use for palette mode coding a current block may be based on an input video signal including the current block or based on some change in bit depth precision. a prediction residual for the current block is encoded to a bitstream along with syntax elements indicative of the bit depth used for the palette mode coding of the current block. in particular, the syntax elements include a first element indicating the palette mode coding bit depth used and a second element indicating whether to apply a bit offset to the palette mode coding bit depth. during decoding, values of the syntax elements are read from the bitstream and used to determine a bit depth for palette mode coding the encoded block.
