23 Claims

1. A method for decoding, from a bitstream, coded sample data of an encoded representation of a video sequence, comprising:

receiving non-sample data for at least a first picture and a second picture;

storing the non-sample data in a decoder memory that comprises a decoded picture buffer (DPB);

receiving first coded sample data for the first picture;

decoding the first coded sample data using the non-sample data to produce first decoded sample data;

storing the first decoded sample data in the DPB;

receiving second coded sample data for the second picture;

removing the first decoded sample data from the DPB;

keeping the non-sample data in the decoder memory based on an obtained storage type indicator;

decoding the second coded sample data using the non-sample data to produce second decoded sample data; and

storing the second decoded sample data in the DPB, wherein

the non-sample data comprises Context Adaptive Binary Arithmetic Coding (CABAC) probability states, adaptive loop filtering (ALF) filter types, ALF parameters, ALF coefficients, coding tree structure parameters, scaling matrices, and/or quantization parameter (QP) modification parameters.
