Decoding a multiview video signal comprises: receiving a bitstream comprising encodings of multiple views of the multiview video signal. Each view comprises multiple pictures segmented into multiple segments. The decoding also comprises extracting flag information associated with a portion of the multiview video signal from the bitstream indicating whether illumination compensation of segments within said portion of the multiview video signal is enabled. For a portion in which illumination compensation is enabled according to the extracted flag information, a value associated with a segment within the portion is extracted from the bitstream and it is determined from said extracted value whether illumination compensation of the segment is to be performed.

There are provided methods and apparatus for stereoscopic video coding using scalable video coding. A scalable video encoder includes an encoder (100) for encoding at least two views corresponding to multi-view video content by, encoding a particular view of the at least two views as a base layer, and encoding each of at least one other view of the at least two views as an enhancement layer using a prediction from a lower layer corresponding to at least one of the particular view and the at least one other view. The at least two views are encoded based on a selection from among at least two of temporal, spatial, and signal to noise ratio scalability techniques.

Multi-view video coding using scalable video coding

Systems and methods are provided for receiving and encoding 3D video. The receiving method comprises: accepting a bitstream with a current video frame encoded with two interlaced fields, in a MPEG-2, MPEG-4, or H.264 standard; decoding a current frame top field; decoding a current frame bottom field; and, presenting the decoded top and bottom fields as a 3D frame image. In some aspects, the method presents the decoded top and bottom fields as a stereo-view image. In other aspects, the method accepts 2D selection commands in response to a trigger such as receiving a supplemental enhancement information (SEI) message, an analysis of display capabilities, manual selection, or receiver system configuration. Then, only one of the current frame interlaced fields is decoded, and a 2D frame image is presented.

Stereoscopic video is encoded and decoded by using the MAC defined by the existing MPEG-4 standard. The stereoscopic video is divided into one image as a single video object, and another image as auxiliary information for the image established as the video object. The auxiliary information includes a horizontal disparity map, a vertical disparity map, luminance residual texture, and chrominance residual texture, which are respectively allocated to auxiliary components of the MAC according to importance and complexity of the images, encoded, and then output as a single encoding stream.

In this paper, we propose a stereoscopic broadcasting system model and a stereoscopic video CODEC that consists of the four layers to code even and odd field corresponding to the left and right video sequences, respectively. The proposed CODEC codes stereoscopic video sequences considering three display devices, the frame/field shuttering display and 2D (2-dimensional) display; devices. Therefore, the field-based stereoscopic video CODEC makes it possible to transmit the coded bit-streams of the only necessary fields to the user's display device and decode those fields even though all of the four fields are not transmitted. The simulation results shows that in the field shuttering display, which is used for PC monitors, the data amount for transmission and decoding is reduced to half of that in MPEG-2 MVP with the almost same quality.
