Abstract:
The present invention is related to a method for moving the position of a base view from an arbitrary GOP (Group Of Pictures) start position to implement an efficient encoding structure in multi-view video encoding. The existing multi-view video encoding method exhibits low encoding efficiency when correlation between the base view and a dependent view is low, since the base view is assumed to be fixed. Moreover, in case the view in a live broadcasting program desired by a producer changes from the base view to another, the user has to consume more bit streams and decoder complexity than those consumed when decoding is performed with respect to the base view. Therefore, to alleviate the drawbacks of the existing multi-view video encoding method, the present invention provides a method for designing syntax elements by which the base view can be moved, thereby supporting an efficient encoding structure.

Claim (Index 5):
A non-transitory computer-readable medium storing a bitstream that is generated by a method for video encoding that supports multi-layer videos, the method comprising:\n encoding a first layer dependency on a current layer into a video parameter set (VPS) extension; encoding a second layer dependency on a current slice in the current layer into a slice unit, wherein the encoding the second layer dependency on the current slice comprises determining, for the current slice, whether to use the first layer dependency to be encoded into the VPS extension or the second layer dependency to be encoded into the slice unit; and constructing a reference picture list for the current slice based on either one or both of the first layer dependency on the current layer or the second layer dependency on the current slice; wherein the reference picture list comprises a temporal reference picture belonging to a same layer as the current slice and an inter-layer reference picture belonging to a different layer from the current slice, and wherein the inter-layer reference picture has a same picture order count (POC) value as the current slice.
