摘要： This disclosure describes techniques for generating depth maps for video units, such as video frames or slices video frames. The techniques may be performed by a video encoder in order to convert two-dimensional (2D) video to three-dimensional (3D) video. The techniques may alternatively be performed by a video decoder in order to convert received 2D video to 3D video. The techniques may use a combination of motion and color considerations in the depth map generation process.

In an example, the method includes obtaining, from an encoded bitstream, one or more network abstraction layer (NAL) units for each view component of a plurality of view components of encoded video data, where each view component of the plurality of view components corresponds to a common temporal location, and where the one or more NAL units encapsulate at least a portion of the encoded video data for the respective view components and include information indicative of a decoding order of the respective view components. The method also includes obtaining information, separate from the NAL units, indicating relationships between view identifiers for the views and the decoding order of the view components.

摘要： Stereoscopic video data encoded according to a full resolution frame-compatible stereoscopic vide coding process. Such stereoscopic video data consists of a right view and a left that are encoded in half resolution versions in an interleaved base layer and an interleaved enhancement layer. When decoded, the right view and left view are filtered according to two sets of filter coefficients, one set for the left view and one set for the right view. The sets of filter coefficients are generated by an encoder by comparing the original left and right views to decoded versions of the left and right views.

摘要： This disclosure relates to techniques for indicating that a video frame is coded as a generalized P/B (GPB) frame in order to reduce a cost of coding and constructing a second reference picture list in video coding. For a GPB frame, which has identical reference picture lists, signaling and constructing both the first and second reference picture lists may be redundant. The techniques of this disclosure may include coding syntax elements indicating that the video frame is coded as the GPB frame, and coding syntax elements indicating a number of reference pictures and reference picture list construction commands for only a first reference picture list. The techniques also include constructing the first reference picture list based on the syntax elements, and then creating the second reference picture list as a duplicate of the first reference picture list.
