21 May 2020TL;DR: In this paper, a decoder parses sequence processing set (SPS) data from an input coded bitstream to detect that an HDR extension syntax structure is present in the parsed SPS data.
Abstract: In a method to improve the coding efficiency of high-dynamic range (HDR) images, a decoder parses sequence processing set (SPS) data from an input coded bitstream to detect that an HDR extension syntax structure is present in the parsed SPS data. It extracts from the HDR extension syntax structure post-processing information that includes one or more of a color space enabled flag, a color enhancement enabled flag, an adaptive reshaping enabled flag, a dynamic range conversion flag, a color correction enabled flag, or an SDR viewable flag. It decodes the input bitstream to generate a preliminary output decoded signal, and generates a second output signal based on the preliminary output signal and the post-processing information.

04 Dec 2013TL;DR: In this article, scaling and rounding parameters for a separable up-scaling filter are determined for video data with high bit-depth, and intermediate data are generated by scaling the second up-sampled data using a second shift parameter.
Abstract: The precision of up-sampling operations in a layered coding system is preserved when operating on video data with high bit-depth. In response to bit-depth requirements of the video coding or decoding system, scaling and rounding parameters are determined for a separable up-scaling filter. Input data are first filtered across a first spatial direction using a first rounding parameter to generate first up-sampled data. First intermediate data are generated by scaling the first up-sampled data using a first shift parameter. The intermediate data are then filtered across a second spatial direction using a second rounding parameter to generate second up-sampled data. Second intermediate data are generated by scaling the second up-sampled data using a second shift parameter. Final up-sampled data may be generated by clipping the second intermediate data.

06 Sep 2012TL;DR: A decoder receives for decoding and post-processing for display an HDR (high dynamic range) image comprising a first coded image (e.g., a JPEG-HDR baseline image) and a second coded image as mentioned in this paper.
Abstract: A decoder receives for decoding and post-processing for display an HDR (high dynamic range) image comprising a first coded image (e.g., a JPEG-HDR baseline image) and a second coded image (e.g., a JPEG-HDR ratio image). The first coded image is partially decoded and post-processed according to a post-processing command (e.g., scaling) to output a first decoded and post-processed image. The second coded image is also partially decoded and post-processed according to the post-processing command to output a second decoded and post-processed image. The first and the second decoded and post-processed images are combined to output a decoded HDR image according to the post-processing command.

TL;DR: In this paper, a variable area sound track is scanned laterally to derive width-modulated pulses which can be demodulated to audio, and each pulse is initiated by a black-to-clear transition sensed in the scanning but is not terminated until it is certain that the clear-toblack transition has been reached, e.g. at reference instants of time.
Abstract: A variable area sound track is scanned laterally to derive width-modulated pulses which can be demodulated to audio. In order to eliminate the effect of noise on the clear area of the track, each pulse is initiated by a black-to-clear transition sensed in the scanning but is not terminated until it is certain that the clear-to-black transition has been reached, e.g. at reference instants of time.

13 Jul 2010TL;DR: In this article, a ramping pattern and/or blanking pattern is applied to control values for the backlight and display modulation layer of a display, based on the difference between new and old control values.
Abstract: Methods and systems are provided for processing control values for a backlight and/or a display modulation layer of a display A ramping pattern is determined based on the difference between new and old control values A blanking pattern is determined based on the motion detected in frame regions The ramping pattern or blanking pattern may take into consideration the display modulation layer response characteristics The ramping pattern and/or blanking pattern is applied to control values for the backlight and/or display modulation layer
