Reducing reference picture set signal overhead on an electronic device
First Claim
Patent Images
1. A method for reducing signal overhead on an electronic device, comprising:
- obtaining a picture;
encoding the picture;
indicating a reference picture set (RPS) corresponding to the picture based on an initialized index value;
sending an indication to delete at least one reference picture listed in a previously provided RPS, wherein the indication comprises a bit field in a slice header of a picture; and
sending a bitstream.

11. A method for decoding a picture on an electronic device, comprising:
-
obtaining a bitstream; obtaining a group of pictures (GOP) based on the bitstream; deriving a partial reference picture set (RPS) from a full RPS based on at least one relative index value, wherein deriving a partial RPS comprises; iterating over each picture in the GOP; identifying a current picture, wherein the at least one relative index value corresponds to the current picture; iterating over the at least one relative index value within the full RPS of the current picture; determining whether a reference picture is available for the at least one relative index value; and adding the picture to the partial RPS if the reference picture is available; and decoding a picture. - View Dependent Claims (12)
