Reference picture management in video coding
First Claim
Patent Images
1. A method for encoding a sequence of pictures comprising:
- using one or more pictures as reference pictures;
labeling the reference pictures with a first parameter;
signaling the first parameter to a decoder; and
using a reference picture management;
wherein all the reference pictures are identified by a second parameter which is derived on the basis of the first parameter.
