Decoding a picture based on a reference picture set on an electronic device
A method for decoding a picture on an electronic device is described. The method includes obtaining a bitstream. The method also includes obtaining a current picture. The method further includes obtaining a relative reference picture set (RPS) parameter. The method additionally includes initializing an index value. Furthermore, the method includes processing another RPS parameter based on the index value. The method also includes decoding the current picture.
1. A method for decoding a video bitstream, comprising:
identifying a reference picture set from the video bitstream, wherein the bitstream includes at least one flag corresponding to at least one reference picture of the reference picture set, wherein a current picture associated with the reference set is encoded in the bitstream; and
decoding the current picture from the bitstream using inter prediction with the reference picture set and the at least one flag, wherein the at least one flag indicates keeping the at least one reference picture for decoding subsequent pictures.
2. The method of claim 1 , wherein identifying the reference picture set is based on a slice header obtained from the bitstream.
3. A method for encoding a video bitstream comprising:
generating a reference picture set for a current picture of the video bitstream;
encoding a block of the current picture using inter prediction with said reference picture set;
sending said reference picture set to the video bitstream;
sending at least one flag corresponding to at least one reference picture of the reference picture set, in the video bitstream, wherein the at least one flag indicates keeping at least one reference picture for decoding subsequent pictures; and
sending the encoded block to the video bitstream.
4. The method of claim 3 , wherein sending the reference picture set comprises sending said reference picture set in a slice header.
5. An electronic device for decoding a video bitstream, comprising:
a processor;
a memory in electronic communication with the processor;
instructions stored in the memory, the instructions being executable to:
identify a reference picture set from the bitstream wherein the bitstream includes at least one flag corresponding to at least one reference picture of the reference picture set, wherein a current picture associated with the reference set is encoded in the bitstream; and
decode the current picture from the bitstream using inter prediction with the reference picture set and the at least one flag,
wherein the at least one flag indicates keeping the at least one reference picture for decoding subsequent pictures.
6. The electronic device of claim 5 , wherein identifying the reference picture set is based on a slice header obtained from said video bitstream.
7. An electronic device for encoding a video bitstream, comprising:
a processor;
a memory in electronic communication with the processor;
instructions stored in the memory, the instructions being executable to:
generate a reference picture set;
encode a block of a current picture using inter prediction with said reference picture set;
send said reference picture set to the bitstream;
send at least one flag corresponding to at least one reference picture of the reference picture set, in the video bitstream, wherein the at least one flag indicates keeping at least one reference picture for decoding subsequent pictures; and
send the encoded data to the video bitstream.
8. The electronic device of claim 7 , wherein sending the reference picture set comprises sending said reference picture set in a slice header.
