    摘要: The invention provides a method that reduces degradation in the perceived quality of images in a video sequence due to data loss. This effect is achieved by effectively delaying the insertion of an INTRA coded frame after a periodic INTRA frame refresh, INTRA update request, or scene cut. Frames associated with INTRA frame requests are not themselves coded in INTRA format, but instead a frame occurring later in the video sequence is chosen for coding in INTRA format. Preferably, the actual INTRA frame is selected such that it lies approximately mid-way between periodic INTRA requests. Frames occurring prior to the actual INTRA coded frame are encoded using temporal prediction, in reverse order, starting from the actual INTRA frame, while those frames occurring after the INTRA coded frame are encoded using temporal prediction in the forward direction.

    摘要: Joint coding of depth map video and texture video is provided, where a motion vector for a texture video is predicted from a respective motion vector of a depth map video or vice versa. For scalable video coding, depth map video is coded as a base layer and texture video is coded as an enhancement layer(s). Inter-layer motion prediction predicts motion in texture video from motion in depth map video. With more than one view in a bit stream (for multi view coding), depth map videos are considered monochromatic camera views and are predicted from each other. If joint multi-view video model coding tools are allowed, inter-view motion skip issued to predict motion vectors of texture images from depth map images. Furthermore, scalable multi-view coding is utilized, where interview prediction is applied between views in the same dependency layer, and inter-layer (motion) prediction is applied between layers in the same view.
