摘要:
Stereoscopic images are subsampled and placed in a “checkerboard” pattern in an image. The image is encoded in a monoscopic video format. The monoscopic video is transmitted to a device where the “checkerboard” is decoded. Portions of the checkerboard (e.g., “black” portions) are used to reconstruct one of the stereoscopic images and the other portion of the checkerboard (e.g., “white” portions) are used to reconstruct the other image. The subsamples are, for example, taken from the image in a location coincident to the checkerboard position in which the subsamples are encoded.

摘要:
Controlling a feature of an encoding process for regions of an image pattern representing more than one image when the regions include an amount of disparity in the represented images that would result in cross-contamination between the represented images if encoded with the feature. The control may be, for example, any of turning the encoding feature off, using the encoding feature less often than when encoding an image pattern representing a single image, negatively biasing the encoding feature, and enabling the encoding feature for regions determined to have zero or near zero disparity and disabling the feature for all other regions. The represented images comprise, for example, any of a stereoscopic view, multiple stereoscopic views, multiple views of a same scene, and multiple unrelated views.

Multi-layered frame-compatible video delivery is described. Multi-layered encoding and decoding methods, comprising a base layer and at least one enhancement layer with reference processing, are provided. In addition, multi-layered encoding and decoding methods with inter-layer dependencies are described. Encoding and decoding methods that are capable of frame-compatible 3D video delivery are also described.

摘要:
Encoding and decoding architectures for 3D video delivery are described, such as 2D compatible 3D video delivery and frame compatible 3D video delivery. The architectures include pre-processing stages to pre-process the output of a base layer video encoder and/or decoder and input the pre-processed output into an enhancement layer video encoder and/or decoder of one or more enhancement layers. Multiplexing methods of how to combine the base and enhancement layer videos are also described.
摘要:
Enhancement methods for sampled and multiplexed image and video data are described. Each component picture is separately processed either after de-multiplexing or on the fly. Processing and de-multiplexing can be combined in a single joint step. The methods apply to both encoding and decoding system and include applications to scalable video coding systems.
摘要:
A device includes a coder or a codec configured for interleaved image data utilizing diamond shaped blocks for motion estimation and/or motion compensation and utilizing square or orthogonal transforms of residual data. In various embodiments, the decoder may be configured, among others, to perform de-blocking on edges of the diamond shaped blocks and/or data padding at boundaries of the image data. Additionally a method is proposed in which at least one of a transform and quantization process to be applied to de-multiplexed data is modified. One application is to combine left and right stereoscopic images, interleaved in a checkerboard manner.
摘要:
Video data that represents two or more views is coded. The regions of the views are asymmetrically processed according to different coding patterns. Techniques that impose asymmetry at the region level, but at the same time may consider overall/average symmetry or significantly reduced asymmetry at the picture/view level are presented.
摘要:
Methods and systems for coding applications are described, where multiple coding passes are performed for purposes of rate control. Prediction structures are generated and used by the multiple coding passes to update coding statistics generated prior to the coding passes. The updated coding statistics are used for a subsequent coding operation.
