Reference Picture Management in Video Coding - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240130835 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 based on the default number of active entries, and obtaining reconstructed blocks of the current slice based on the active entries in the reference picture list.
- Obtaining a reference picture list structure for a current slice in the coded video bitstream
- Obtaining a default number of active entries in the reference picture list for the current slice
- Constructing a reference picture list with active and inactive entries
- Setting the number of active entries in the list equal to the number of entries in the reference picture list structure if the default number is greater
- Obtaining reconstructed blocks of the current slice based on the active entries in the reference picture list

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.
