The method includes obtaining a first reference picture list of a current slice represented in the coded video bitstream and a second reference picture list of the current slice, and marking a status of a reference picture in a decoded picture buffer (DPB) based on the first reference picture list and the second reference picture list when the current slice is a first slice in a current picture to which the current slice belongs. The status of the reference picture in the decoded picture buffer is one of used for short-term reference, used for long-term reference, or unused for reference. The method also includes using the reference picture in a reconstructing process of the current picture or a picture following the current picture when the status of the reference picture is used for short-term reference or used for long-term reference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reference picture management in video coding","description":"A method of decoding a coded video bitstream.
