Reference Picture Management in Video Coding - A simplified explanation of the abstract

This abstract first appeared for US patent application 18521714 titled 'Reference Picture Management in Video Coding

Simplified Explanation

The method described in the abstract involves decoding a coded video bitstream by constructing a reference picture list for a current slice, setting the number of active entries in the list, and obtaining reconstructed blocks based on the active entries.

  • Obtaining a reference picture list structure for a current slice
  • Obtaining a default number of active entries in the reference picture list
  • Constructing a reference picture list with active and inactive entries
  • Setting the number of active entries in the list based on the default number
  • Obtaining reconstructed blocks using the active entries

Original Abstract Submitted

A method of decoding a coded video bitstream includes obtaining a reference picture list structure for a current slice represented in the coded video bitstream, wherein the reference picture list structure contains a number of entries; obtaining a default number of active entries in a reference picture list for the current slice; constructing a reference picture list for the current slice, the reference picture list containing a number of active and inactive entries; setting the number of active entries in the reference picture list equal to the number of entries in the reference picture list structure when the default number of active entries in the reference picture list is greater than the number of entries in the reference picture list structure; and obtaining, based on at least one active entry of the reference picture list, at least one reconstructed block of the current slice.
