Gradual Decoding Refresh In Video Coding - A simplified explanation of the abstract

This abstract first appeared for US patent application 18511215 titled 'Gradual Decoding Refresh In Video Coding

Simplified Explanation

The abstract describes a method for decoding a coded video bitstream using a video decoder. Here is a simplified explanation of the abstract:

• The video decoder determines if a gradual decoding refresh (GDR) picture is the initial picture or follows an end of sequence (EOS) network abstraction layer (NAL) unit.
• A flag is set to prevent the GDR picture from being output in certain cases.
• The GDR picture is decoded and stored in a decoded picture buffer (DPB).

Original Abstract Submitted

A method of decoding a coded video bitstream implemented by a video decoder is provided. The method includes the video decoder determining whether a gradual decoding refresh (GDR) picture in the coded video bitstream is an initial picture in decoding order or the initial picture following an end of sequence (EOS) network abstraction layer (NAL) unit in the decoding order; setting a flag to a value to prevent the GDR picture from being output when the GDR picture is the initial picture in decoding order or the initial picture following the EOS NAL unit in the decoding order; decoding the GDR picture; and storing the GDR picture in a decoded picture buffer (DPB).
