20120314773 | Drift-Free, Backwards Compatible, Layered VDR Coding - A visual dynamic range (VDR) signal and a standard dynamic range (SDR) signal are received. A first (e.g., MPEG-2) encoder encodes a base layer (BL) signal. A second encoder encodes an enhancement layer (EL). The EL signal represents information with which the VDR signal may be reconstructed, e.g., using the BL and the EL signals. The first encoder encodes the SDR signal with inverse discrete cosine transform (IDCT) coefficients that have a fixed precision, e.g., which represent fixed-point approximations of transform coefficients that may have arbitrary precisions. The BL signal is encoded in a stream that conforms with an Advanced Television Standards Committee (ATSC) standard. The EL is encoded in a stream that conforms with an ATSC enhanced vestigial sideband (E-VSB) standard. The BL and EL signals are combined; e.g., multiplexed, and transmitted together. | 12-13-2012 |
20120314944 | HIGH DYNAMIC RANGE, BACKWARDS-COMPATIBLE, DIGITAL CINEMA - HDR images are coded and distributed. An initial HDR image is received. Processing the received HDR image creates a JPEG-2000 DCI-compliant coded baseline image and an HDR-enhancement image. The coded baseline image has one or more color components, each of which provide enhancement information that allows reconstruction of an instance of the initial HDR image using the baseline image and the HDR-enhancement images. A data packet is computed, which has a first and a second data set. The first data set relates to the baseline image color components, each of which has an application marker that relates to the HDR-enhancement images. The second data set relates to the HDR-enhancement image. The data packets are sent in a DCI-compliant bit stream. | 12-13-2012 |
20130033586 | System, Method and Apparatus for Generation, Transmission and Display of 3D Content - A method of and system and apparatus for, generating visual information from left and right (L/R) view information and depth information, comprising computing left and right projections of L/R view information in three-dimensional space, combining the occluded portions of the computed projections in three-dimensional space, and mapping the combined projections to two-dimensional space according to a desired projection point. | 02-07-2013 |
20140029675 | Multiple Color Channel Multiple Regression Predictor - Inter-color image prediction is based on multi-channel multiple regression (MMR) models. Image prediction is applied to the efficient coding of images and video signals of high dynamic range. MMR models may include first order parameters, second order parameters, and cross-pixel parameters. MMR models using extension parameters incorporating neighbor pixel relations are also presented. Using minimum means-square error criteria, closed form solutions for the prediction parameters are presented for a variety of MMR models. | 01-30-2014 |

20140037205 | Image Prediction Based on Primary Color Grading Model - Inter-color image prediction is based on color grading modeling. Prediction is applied to the efficient coding of images and video signals of high dynamic range. Prediction models may include a color transformation matrix that models hue and saturation color changes and a non-linear function modeling color correction changes. Under the assumption that the color grading process uses a slope, offset, and power (SOP) operations, an example non linear prediction model is presented. | 02-06-2014 |
20140098886 | Video Compression Implementing Resolution Tradeoffs and Optimization - Compression transforming video into a compressed representation (which typically can be delivered at a capped pixel rate compatible with conventional video systems), including by generating spatially blended pixels and temporally blended pixels (e.g., temporally and spatially blended pixels) of the video, and determining a subset of the blended pixels for inclusion in the compressed representation including by assessing quality of reconstructed video determined from candidate sets of the blended pixels. Trade-offs may be made between temporal resolution and spatial resolution of regions of reconstructed video determined by the compressed representation to optimize perceived video quality while reducing the data rate. The compressed data may be packed into frames. A reconstruction method generates video from a compressed representation using metadata indicative of at least one reconstruction parameter for spatial regions of the reconstructed video. | 04-10-2014 |

20140341305 | SPECIFYING VISUAL DYNAMIC RANGE CODING OPERATIONS AND PARAMETERS - Coding syntaxes in compliance with same or different VDR specifications may be signaled by upstream coding devices such as VDR encoders to downstream coding devices such as VDR decoders in a common vehicle in the form of RPU data units. VDR coding operations and operational parameters may be specified as sequence level, frame level, or partition level syntax elements in a coding syntax. Syntax elements in a coding syntax may be coded directly in one or more current RPU data units under a current RPU ID, predicted from other partitions/segments/ranges previously sent with the same current RPU ID, or predicted from other frame level or sequence level syntax elements previously sent with a previous RPU ID. A downstream device may perform decoding operations on multi-layered input image data based on received coding syntaxes to construct VDR images. | 11-20-2014 |
20140376612 | Dual-Layer Backwards-Compatible Progressive Video Delivery - Given an input progressive sequence, a video encoder creates a dual-layer stream that combines a backwards-compatible interlaced video stream layer with an enhancement layer to reconstruct full-resolution progressive video. Given two consecutive frames in the input progressive sequence, vertical processing generates a top field-bottom field (TFBF) frame in a base layer (BL) TFBF sequence, and horizontal processing generates a side-by-side (SBS) frame in an enhancement layer (EL) SBS video sequence. The BL TFBF and the EL SBS sequences are compressed together to create a coded, backwards compatible output stream. | 12-25-2014 |
