Abstract:
According to the present invention, the position of a base view moves from an arbitrary GOP starting position for the purpose of an effective coding structure in coding a multi-view video. A scheme of coding a multi-view video according to the related art uses a fixed base view, so that, when a correlation between the base view and the dependent view is low, the coding efficiency is deteriorated. In addition, when a view at which a producer would like to show a video in real time moves to another view, complexity of a bit-stream and a decoder is spent much more than that when a user decodes the base view. Thus, according to the present invention, a syntax element which may move the base view is designed to support an effective coding structure, so that the above problems may be solved.
Abstract:
Disclosed are a method and an apparatus for encoding/decoding an image, which support a plurality of layers. The method of decoding an image includes the steps of: interpreting layer dependence on a current layer in a VPS(Video Parameter Set) extension; interpreting the layer dependence on the current slice in a slice by determining whether the layer dependence is not used for the current slice or a new layer dependence in a range of the interpreted layer dependence in the VPS extension is used; and constituting a reference picture list about the current layer based on at least one of the layer dependence interpreted in the VPS and the slice.
Abstract:
The present invention relates to image encoding and decoding of a structure including at least one layer, quality, space, and view and, more particularly, to a method for predicting an upper layer signal using one or more reference layers when encoding and decoding the upper layer. The method can improve encoding efficiency by separating a space quality reference layer list, which comprises space and quality layers referred within the same view as the relevant layer, from a view reference layer list, which comprises space and quality layers the same as the relevant layer; and by predicting between layers by taking into consideration the characteristics of each layer, when encoding and decoding an encoding and decoding image of the upper layer.
Abstract:
A video decoding method according to the present invention may comprise the steps of receiving a supplemental enhancement information (SEI) message containing information on a parameter set to be activated; parsing the information on the parameter set; and using the parsed information on the parameter set.
Abstract:
A video encoding method according to the present invention may comprise the steps of figuring out reference picture information to which a slice refers; encoding a slice header containing the reference picture information; and transmitting a bitstream including the slice header.
