Patent ID: 10602156

Abstract:
An encoded bitstream of data including a plurality of encoded pictures is received. It is determined whether a first instantaneous decoding refresh (IDR) picture has one or more subsequent leading pictures included in the plurality of encoded pictures based on a Network Access Layer (NAL) unit type associated with the first IDR picture. The first IDR picture occurs at a random-access point in the encoded bitstream of data. When the NAL unit type of the first IDR picture is a first value indicating that the first IDR picture has one or more subsequent leading pictures, (i) the one or more subsequent leading pictures are decoded with reference to the first IDR picture based on the NAL unit type of the first IDR picture being the first value, and (ii) an output order is generated for the first IDR picture and the one or more subsequent leading pictures such that the one or more subsequent leading pictures precede the first IDR picture in the output order.
