Methods and apparatus using virtual reference pictures
First Claim
Patent Images
1. An apparatus, comprising:
- an encoder for encoding at least one picture, using at least one virtual reference picture, to form a resultant bitstream, wherein the at least one virtual reference picture is different than a previously decoded picture, and the at least one virtual reference picture is stored in a decoded picture buffer that also stores non-virtual reference pictures.

Abstract
There are provided methods and apparatus using virtual reference pictures. An apparatus includes an encoder for encoding at least one picture, using at least one virtual reference picture, to form a resultant bitstream. The at least one virtual reference picture is different than a previously decoded picture.

57. In a video decoder, a method, comprising:
decoding at least one picture, using at least one virtual reference picture, from a bitstream, wherein the at least one virtual reference picture is different than a previously decoded picture, and the at least one virtual reference picture is stored in a decoded picture buffer that also stores non-virtual reference pictures. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 79, 83, 87)

75. A non-transitory computer readable storage media having video signal data encoded thereupon, comprising:
at least one picture, encoded using at least one virtual reference picture, to form a resultant bitstream, wherein the at least one virtual reference picture is different than a previously decoded picture, and the at least one virtual reference picture is stored in a decoded picture buffer that also stores non-virtual reference pictures.
