Abstract
Disclosed herein is a method of encoding video signals. The method includes creating a bit stream of a first layer by encoding the video signals, and creating a bit stream of a second layer by encoding the video signals based on the first layer. When residual data, corresponding to an image difference, within the first layer, is up-sampled and used for the encoding of the second layer, the residual data is up-sampled for each block that is predicted based on motion compensation.
Claims18
A method of encoding video signals, comprising:
- creating a bit stream of a first layer by encoding the video signals;
- and
- creating a bit stream of a second layer by encoding the video signals based on the first layer;
- wherein, when residual data, corresponding to an image difference, within the first layer, is up-sampled and used for the encoding of the second layer, the residual data is up-sampled on the basis of a block that is predicted according to motion compensation.
A method of encoding video signals, comprising:
- creating a bit stream of a first layer by encoding the video signals;
- and
- creating a bit stream of a second layer by encoding the video signals based on the first layer;
- wherein, when the first layer is up-sampled and used for the encoding of the second layer, different up-sampling methods are respectively applied to luminance data and chrominance data.
A method of decoding an encoded video bit stream, comprising:
- decoding a bit stream of a first layer;
- and
- decoding a bit stream of a second layer based on the first layer;
- wherein, when residual data, corresponding to an image difference, within the first layer, is up-sampled and used for the decoding of the second layer, the residual data is up-sampled on the basis of a block that is predicted according to motion compensation.
A method of decoding an encoded video bit stream, comprising:
- decoding a bit stream of a first layer;
- and
- decoding a bit stream of a second layer based on the first layer;
- wherein, when the first layer is up-sampled and used for the decoding of the second layer, different up-sampling methods are respectively applied to luminance data and chrominance data.
