Abstract: This disclosure describes techniques for estimating a depth of image objects for a two-dimensional (2D) view of a video presentation. For example, a plurality of feature points may be determined for a 2D view. The plurality of feature points may be used to estimate global motion, e.g., motion of an observer (e.g., camera), of the 2D view. For example, the plurality of feature points may be used to generate a global motion frame difference. The global motion frame difference may be used to create a depth map for the 2D view, which may be used to generate an alternative view of the video presentation that may be used to display a three-dimensional (3D) video presentation.

Abstract: This disclosure describes techniques relevant to HTTP streaming of media data. According to these techniques, a server device may signal an open decoding refresh (ODR) random access point (RAP) for a movie segmentation of a movie representation. At least one frame of the media segmentation following the ODR RAP frame in decoding order may not be correctly decoded, and wherein each frame of the media segmentation following the ODR RAP frame in display order can be correctly decoded without relying on content of frames prior to the ODR RAP in display order. According to the techniques of this disclosure, a client device may communicate a request to a server device for the streaming of media data based on signaling of the ODR RAP. Also according to the techniques of this disclosure, a client device may commence decoding and/or playback of the movie representation based on signaling of the ODR RAP.

Abstract: An asymmetric frame of a coded video bitstream may include a full resolution picture of a left view and a reduced resolution picture of a right view, where the left and right views form a stereo view pair for three-dimensional video playback. In one example, an apparatus includes a video encoder configured to receive a first picture of a first view of a scene having a first resolution, receive a second picture of a second view of the scene having a reduced resolution relative to the first resolution, form an asymmetric frame comprising the first picture and the second picture, and encode the asymmetric frame. In this manner, decoders of varying capabilities may receive the same bitstream, and the bitstream may consume less bandwidth than one or more bitstreams having full resolution pictures of a stereo view pair. The bitstream may have better quality than a bitstream having subsampled pictures.
