Abstract
A method of and a device for decoding a video stream including at least two coded video sequences that each use a respective Sequence Parameter Set that differ in at least one value from each other, and each of the at least two video sequences including at least two coded pictures. The method includes decoding and activating, by a decoder, a single Decoder Parameter Set pertaining to the at least two coded video sequences before decoding any coded picture of the at least two video sequences. The method further includes decoding, by the decoder, at least one coded picture of the at least two coded video sequences.
Claims21
A method for decoding a video stream including at least two coded video sequences that each use a respective Sequence Parameter Set that differ in at least one value from each other, and each of the at least two video sequences including at least two coded pictures, and the at least two coded video sequences have different presentation times, the method comprising:
- decoding and activating, by a decoder, a single Decoder Parameter Set pertaining to all video sequences of the video stream before decoding any coded picture of the at least two video sequences;
- and
- decoding, by the decoder, at least one coded picture of the at least two coded video sequences.
A device for decoding a video stream including at least two coded video sequences that each use a respective Sequence Parameter Set that differ in at least one value from each other, and each of the at least two video sequences including at least two coded pictures, and the two coded video sequences have different presentation times, the device comprising:
- a decoder configured to:
- decode and activate a single Decoder Parameter Set pertaining to all video sequences of the video stream before decoding any coded picture of the at least two video sequences;
- and
- decode at least one coded picture of the at least two coded video sequences.
A non-transitory computer-readable medium storing instructions, the instructions comprising:
- one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to:
- decode and activate a single Decoder Parameter Set pertaining to all video sequences of a video stream before decoding any coded picture of at least two coded video sequences of the video stream;
- and
- decode at least one coded picture of the at least two coded video sequences, wherein
- the at least two coded video sequences each use a respective Sequence Parameter Set that differ in at least one value from each other, and each of the at least two video sequences including at least two coded pictures, and the at least two coded video sequences have different presentation times.
