Publication number: 20180098046Abstract: Given existing color remapping information (CRI) messaging variables, methods are described to communicate color volume information for a targeted display to a downstream receiver. Bits 7:0 of the 32-bit colour_remap_id are used to extract a first value. If the first value is not a reserved value, then the first value is used as an index to a look-up table to generate a first luminance value for a targeted display, otherwise a second value is generated based on bits 31:9 in the colour_remap_id messaging variable and the first luminance value for a targeted display is generated based on the second value. The methods may be applied to communicate via CRI messaging a minimum luminance value, a maximum luminance value, and color primaries information of the targeted display.Type: ApplicationFiled: October 3, 2017Publication date: April 5, 2018Applicant: Dolby Laboratories Licensing CorporationInventors: Walter J. Husak, Robin Atkins, Peng Yin, Taoran Lu, Tao Chen

Publication number: 20180084278Abstract: 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.Type: ApplicationFiled: November 30, 2017Publication date: March 22, 2018Inventors: Alexandros Tourapis, Walter J.

Publication number: 20180070071Abstract: 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.Type: ApplicationFiled: November 9, 2017Publication date: March 8, 2018Applicant: Dolby Laboratories Licensing CorporationInventors: Walter J.

Publication number: 20170214916Abstract: A processor for forward reshaping to a target bit depth receives an input image with an input bit depth. The input luminance range is divided into luminance bands and each band is assigned a visual importance index. The output codewords at the target bit depth are divided into codeword bins and each bin is assigned to one of the luminance bands. Each codeword bin is assigned the visual importance index of the luminance band it belongs. Each bin is allocated a number of reshaped codewords according to its visual importance index and a codeword mapping function, where bins with the highest importance index are allocated more codewords than the other bins. A signal reshaping function is generated based on the allocation of codewords, and the reshaping function is applied to the input image to generate an output image in the target bit depth.Type: ApplicationFiled: January 19, 2017Publication date: July 27, 2017Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Taoran LU, Fangjun PU, Peng YIN, Tao CHEN, Walter J.

Publication number: 20160366422Abstract: Sample data and metadata related to spatial regions in images may be received from a coded video signal. It is determined whether specific spatial regions in the images correspond to a specific region of luminance levels. In response to determining the specific spatial regions correspond to the specific region of luminance levels, signal processing and video compression operations are performed on sets of samples in the specific spatial regions. The signal processing and video compression operations are at least partially dependent on the specific region of luminance levels.Type: ApplicationFiled: February 19, 2015Publication date: December 15, 2016Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Peng YIN, Guan-Ming SU, Taoran LU, Tao CHEN, Walter J.
