Abstract
A video codec is provided. A coded first frame image is decoded and stored. A second frame is coded by referring to the decoded first frame image. The second frame image is not used as a reference image. For this purpose, the second frame image does not pass through a decoding module/decoding process for creating a reference image.
Claims20
A method of encoding a moving picture, the moving picture having a first frame image coded without referring to other frame images and a second frame image coded by referring to other frame images, the method comprising:
- coding the first frame image;
- decoding the coded first frame image and storing the decoded first frame image;
- and
- coding the second frame image by referring to the decoded first frame image,
- wherein a decoding for use the second frame image as a reference image is not performed on the coded second frame image.
A method of encoding a moving picture, comprising:
- coding a first frame image, which does not refer to other frame image, with accompanying a decoding;
- and
- coding a second frame image, which refers to other frame image, by referring to the decoded first frame image without decoding.
An apparatus of encoding a moving picture in a video codec, the moving picture having a first frame image coded without referring to other frame images and a second frame image coded by referring to other frame images, the apparatus comprising:
- a first coder for coding the first frame image;
- a decoder for decoding the coded first frame image and storing the decoded first frame image;
- and
- a second coder for coding the second frame image by referring to the decoded first frame image, without decoding.
