Abstract
An inter-layer prediction method and device for a multi-layer video. The inter-layer prediction method includes the steps of: generating a restored picture in a reference layer through the predictive coding of the reference layer, determining when there is a restored picture in the reference layer for the time corresponding to a current picture in an enhancement layer for coding or decoding of the current picture in the enhancement layer, and performing inter-layer prediction by referencing a picture in the enhancement layer or a restored picture in the reference layer, depending on whether there is restored picture from the same view in the reference layer.
Claims2
An inter-layer prediction apparatus for a multi-layer video, comprising:
- a frame buffer configured to store a reconstructed picture in an enhancement layer and a reconstructed picture in a reference layer;
- a predictor configured to
- determine whether the reconstructed picture in the reference layer is present at a time corresponding to a current picture in the enhancement layer,
- determine an inter-layer reference picture for the current picture, in response to the determination that the reconstructed picture is present at the time corresponding to the current picture,
- generate a reference picture list for the current picture including the inter-layer reference picture and the reconstructed picture in the enhancement layer, and
- generate a predicted picture of the current picture by performing inter prediction on the current picture based on the reference picture list;
- and
- an adder configured to generate a reconstructed picture of the current picture by adding the predicted picture of the current picture and a residual picture of the current picture.
