Abstract
In a method performed by an encoder according to a first aspect a one-bit flag is signaled, wherein the one-bit flag is associated with a reference picture in a buffer description for the current picture. The one-bit flag is set to explicitly indicate to a decoder if the reference picture should be included in a list of reference pictures or not included in the list of reference pictures. The list of reference pictures indicates which pictures that can be used for decoding the current picture.
Claims13
A decoder for decoding a representation of a current picture of a video stream of multiple pictures using reference pictures, wherein the decoder is configured to decode a one-bit flag associated with a reference picture in a buffer description for the current picture, the decoder comprises a processor configured to check the one-bit flag for each reference picture in the buffer description where the corresponding reference picture in a decoded picture buffer is missing and if the one-bit flag is indicating that the reference picture is included in the reference picture list, the processor is configured to conclude that the picture is unintentionally lost.
A method of decoding a representation of a current picture of a video stream of multiple pictures using reference pictures, implemented in a processor of a decoder, the method comprising:
- decoding a one-bit flag associated with a reference picture in a buffer description for the current picture;
- checking the one-bit flag for each reference picture in the buffer description where the corresponding reference picture in a decoded picture buffer is missing and if the one-bit flag is indicating that the reference picture is included in the reference picture list, concluding that the picture is unintentionally lost.
