Title:
A METHOD AND APPARATUS FOR VIDEO ENCODING AND DECODING
Document Type and Number:
WIPO Patent Application WO/2009/033432
Kind Code:
A1
Abstract:
A method and an equipment used for encoding and decoding video are provided. The
detail of the them is: At the encoder side, an image is divided into some slices.
Each slice includes consecutive macro blocks in designated scanning order in
the image. Then the slices included in the image are divided into one or many slice
sets according to the attribute information of each slice. Based on the division
information of the slices and the slice sets, the encoding operation to the slices
in the slice sets is carried on and code stream corresponding to the image is produced.
At the decoder side, division information of the slices and slice sets iscaptured
from the code stream to be decoded. The operation of decoding is processed according
to the division information. The method and the equipment have application to
encoding based on areas, and can improve efficiently transmission capability
and reduce complexity of encoding and decoding system as a result of easily realizing
process.
