VIDEO ENCODING APPARATUS, VIDEO ENCODING METHOD, VIDEO DECODING APPARATUS, AND VIDEO DECODING METHOD

摘要

A video encoding apparatus includes: a buffer memory that stores encoded field pictures; a controller that adds reference pair information to each of multiple field pictures, the reference pair information specifying a field picture to be paired when creating a frame picture; a buffer interface that generates, when inter-predictive coding is performed by using, as a coding target picture, a frame picture created by interleaving two field pictures that are not encoded, a frame picture as a reference picture by interleaving the field pictures of the pair specified with reference to the reference pair information of a stored encoded field picture; and an encoder that generates, when the coding target picture is a frame picture, encoded data by performing inter-predictive coding on the coding target picture on a frame-picture-by-frame-picture basis by use of the reference picture.

主权项

1. A video encoding apparatus that performs inter-predictive coding on a plurality of field pictures included in a video, the video encoding apparatus comprising:
a buffer memory that stores an encoded field picture among the plurality of field pictures; a controller that adds reference pair information to each of the plurality of field pictures when a frame picture is to be created by interleaving two field pictures forming a pair, the reference pair information specifying a different field picture to form the pair; a buffer interface that generates, when inter-predictive coding is performed by using, as a coding target picture, a frame picture created by interleaving two field pictures that are not encoded among the plurality of field pictures, a frame picture as a reference picture by interleaving the field pictures of the pair specified with reference to the reference pair information of an encoded field picture stored in the buffer memory; an encoder that generates, when the coding target picture is a frame picture, encoded data by performing inter-predictive coding on the coding target picture on a frame-picture-by-frame-picture basis by use of the reference picture; and an entropy encoder that performs entropy coding on the encoded data and the reference pair information to generate encoded video data including the entropy-encoded reference pair information.
