Abstract

A method of decoding a coded video bitstream is provided. The method includes obtaining a reference picture list structure for a current slice represented in the coded video bitstream; constructing areference picture list for the current slice based on the reference picture list structure such that a number of entries in the reference picture list and an order of the entries in the reference picture list are both the same as in the reference picture list structure, wherein the reference picture list contains a plurality of active entries and a plurality of inactive entries; and obtaining, based on at least one active entry of the reference picture list, at least one reconstructed block of the current slice.

Description

[0001] Related Application Cross Reference [0002] This patent application claims the rights and interests of the U.S. Provisional Patent Application No. 62 / 719,360 filed on August 17, 2018 by Wang Yekui et al., entitled "Reference Picture Management in Video Coding" , the entire contents of which are incorporated herein by reference. technical field [0003] This disclosure generally relates to reference picture management techniques for use in video coding. More specifically, this disclosure describes techniques for building reference picture lists and identifying reference pictures. Background technique [0004] Large amounts of video data need to be described even in the case of short videos, which can cause difficulties when the data is to be sent or otherwise transmitted over communication networks with limited bandwidth capacity. Therefore, video data is usually compressed before being sent over modern telecommunications networks. Since memory resources may be lim...
