Problems solved by technology

In the temporal case (such as AVC), this problem is very complicated, but when encoding pictures in video standards (such as MVC) when it is necessary to consider reference pictures in different viewpoints (such as figure 1 shown), this becomes a problem of obtaining a reference image

Embodiment approach

[0066] The first embodiment of the principle of the present invention initializes all temporal images of the current viewpoint according to the definition in the MPEG-4 AVC specification. This initialized list is then truncated by the values ​​specified in num_ref_idx_l0_active_minus1 and num_ref_idx_l1_active_minus1 for LIST_0 and LIST_1, respectively.

[0067] After these pictures, the cross-view reference pictures defined in the SPS of the MVC specification are inserted and truncated by the values ​​specified in num_ref_idx_l0_active_view_minus1 and num_ref_idx_l1_active_view_minus1 for LIST_0 and LIST_1.

[0068] In order for the reference picture list reordering commands specified in the current MVC specification to work correctly, the present invention imposes a restriction that these commands only work on temporal reference pictures. RPLR processing can be performed immediately after the initialization of the temporal pictures and before the cross-view reference, or aft...

Abstract

The invention describes a method of image reference list sorting for a multi-view encoder for encoding a moving image, wherein an image list has a coding sequence of a reference image, used to correlate whether an image to be encoded is associated with a viewpoint to encode aspecified image (715). The sequence of the image list depends on time relationship (720) between the reference image and the image to be encoded, and the viewpoint (715) associated with the reference image changes the coding sequence of the reference images in the image reference list.

Description

[0001] This application is a divisional application of a patent application with an application date of October 12, 2007, an application number of 200780038178.3, and an invention title of "Reference Image List Management Grammar for Multi-Viewpoint Video Coding". [0002] Cross References to Related Applications [0003] This application claims priority to US Provisional Application 60 / 851,863, filed October 13, 2006, and US Provisional Application 60 / 851,521, filed October 13, 2006, both of which are hereby incorporated by reference in their entirety. technical field [0004] The present invention relates to the field of moving pictures, and more particularly, to the issue of ordering reference pictures when used to encode video pictures. Background technique [0005] Many inter-coding systems use a reference picture, which helps reduce the size of the coded bitstream. The result of this is that the coding efficiency is higher than using only intra coding techniques. Con...
