SYSTEMS AND METHODS FOR SIGNALING REFERENCE PICTURES IN VIDEO CODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240056608 titled 'SYSTEMS AND METHODS FOR SIGNALING REFERENCE PICTURES IN VIDEO CODING

Simplified Explanation

The abstract describes a method for determining a reference index for a reference picture list in a video coding system. Here are the key points of the patent application:

  • Decoding the reference picture list structure from a sequence parameter set or a slice header.
  • Deriving a reference index based on the value of a reference picture list flag.
  • Decoding the number of reference index active syntax in the slice header if there are more than one entry in the reference picture list structure.
  • Defining the number of reference index active syntax as "i".
  • Deriving a variable by adding one to the value of the number of reference index active syntax.
  • Specifying a maximum reference index for the reference picture list by subtracting one from the value of the variable.

Potential applications of this technology:

  • Video coding and compression systems
  • Video streaming services
  • Video surveillance systems

Problems solved by this technology:

  • Efficient reference picture list management in video coding systems
  • Improved video compression and transmission

Benefits of this technology:

  • Enhanced video quality
  • Reduced bandwidth usage
  • Improved video coding efficiency


Original Abstract Submitted

a method for determining a reference index for a reference picture list is disclosed. a reference picture list structure in one of a sequence parameter set and a slice header is decoded. a reference index for the reference picture list structure is derived according to a value of a reference picture list flag. a number of reference index active syntax in the slice header is decoded, if a number of entries in the reference picture list structure is greater than 1. the number of reference index active syntax is defined for i. a variable is derived by adding one to a value of the number of reference index active syntax. a value subtracted one from a value of the variable specifies a maximum reference index for the reference picture list.
