    Abstract: Embodiments feature families of rate allocation and rate control methods that utilize advanced processing of past and future frame/field picture statistics and are designed to operate with one or more coding passes. At least two method families include: a family of methods for a rate allocation with picture look-ahead; and a family of methods for average bit rate (ABR) control methods. At least two other methods for each method family are described. For the first family of methods, some methods may involve intra rate control. For the second family of methods, some methods may involve high complexity ABR control and/or low complexity ABR control. These and other embodiments can involve any of the following: spatial coding parameter adaptation, coding prediction, complexity processing, complexity estimation, complexity filtering, bit rate considerations, quality considerations, coding parameter allocation, and/or hierarchical prediction structures, among others.

    Abstract: 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.

    Abstract translation: 立体图像被二次采样并放置在图像中的“棋盘”图案中。 图像以单视频视频格式编码。 单视频视频被传送到“棋盘”被解码的设备。 棋盘的部分（例如“黑色”部分）用于重构立体图像之一，并且棋盘的其他部分（例如，“白色”部分））用于重构另一图像。 子样本例如是从与子样本被编码的棋盘棋位置重合的位置处取自图像。

    Abstract: Sampled data is packaged in checkerboard format for encoding and decoding. The sampled data may be quincunx sampled multi-image video data (e.g., 3D video or a multi-program stream), and the data may also be divided into sub-images of each image which are then multiplexed, or interleaved, in frames of a video stream to be encoded and then decoded using a standardized video encoder. A system for viewing may utilize a standard video decoder and a formatting device that de-interleaves the decoded sub-images of each frame reformats the images for a display device. A 3D video may be encoded using a most advantageous interleaving format such that a preferred quality and compression ratio is reached. In one embodiment, the invention includes a display device that accepts data in multiple formats.
