Embodiment Construction

[0075] In order to understand the various aspects of the present invention and embodiments related thereto, some closely related aspects of video coding will be briefly described below.

[0076] As an example of a video encoder, decoder, encoding method, decoding method and bitstream structure in which the described embodiments may be implemented, in this section some key definitions of H.264 / AVC, bitstream and encoding structure. Aspects of the invention are not limited to H.264 / AVC, rather, the description herein is presented for one possible basis upon which the invention may be partially or fully implemented.

[0077] The H.264 / AVC standard was developed by the Joint Video Team (JVT) of the Video Coding Experts Group (VCEG) of the International Telecommunication Union's Telecommunication Standardization Sector (ITU-T) and the International Organization for Standardization (ISO) / International Electrotechnical Commission (IEC). Developed by the Picture Experts Group (MPEG)....

Abstract

The invention discloses a method, an apparatus, a server, a client and a non-transitory computer readable medium comprising a computer program stored therein for motion compensated video coding and decoding. Texture block motion information is used to derive disparity / depth motion information. Alternatively, disparity / depth motion information is used to derive texture block motion information.

Description

technical field [0001] The present invention relates to an apparatus, method and computer program for video encoding and decoding. Background technique [0002] Various technologies for providing three-dimensional (3D) video are currently researched and developed. In particular, a great deal of research has focused on various multi-view applications, where a viewer can see only one pair of stereoscopic videos from one specific viewpoint and another pair of stereoscopic videos from a different viewpoint. One of the most feasible approaches for such multi-view applications has been found to be one in which only limited input views are provided to the decoder side, such as monoscopic or stereoscopic video plus some supplementary data, and are then processed locally by the decoder. Render (ie, composite) all required views for display on the display. [0003] Several techniques are available for view rendering, and for example depth image based rendering (DIBR) has proven to b...
