  • Patent number: 11488545
    Abstract: Device comprising: a rear panel comprising a network of backlighting elements, a front panel comprising a network of optical valves which are each capable of modulating the brightness of a single primary colour. By the modulation of chrominance which is added to the modulation of luminance for the backlighting elements of the rear panel, the device according to the invention makes it possible to display the images with even more contrast and better quality. A specific control mode makes it possible to avoid the colour “interferences”.

  • Publication number: 20220337893
    Abstract: A streaming device may request and download multi-layer video segments based on a number of factors including the artistic interest associated with the video segments and/or the status of a buffer area managed by the streaming device. The multi-layer segments may be coded using scalable coding techniques or a combination of scalable coding and simulcast coding techniques by which each of the video segments may be coded into one or more representations of different qualities and/or bitrates. When requesting the multi-layer segments, the streaming device may ensure that the fullness of the buffer area falls between a buffer underflow threshold and a backfilling threshold under various network conditions. The streaming device may estimate the available network bandwidth in order to facilitate the scheduling decisions. The streaming device may consider the artistic interest associated with the video segments during scheduling and may give priority to those segments with higher artistic interest.

  • Publication number: 20220329831
    Abstract: Cross plane filtering may be used for enhanced chroma coding. An indication of a cross-plane filter associated with a current picture may be received. The current picture may include an intra-coded video block and a plurality of reference samples. The plurality of reference samples may be used to predict the intra-coded video block. A luma sample region may be determined in the current picture. The luma sample region may determined to enhance a corresponding chroma sample in the current picture. The cross-plane filter may be applied to a plurality of luma samples in the luma sample region to determine an offset. The cross-plane filter may be a high pass filter. The offset may be applied to the corresponding chroma sample to determine an enhanced chroma sample.

  • Patent number: 11451881
    Abstract: Systems and methods are described for displaying 360-degree video using a viewing direction and/or a viewpoint position that is determined based on a user-selected level of automation. If full automation is selected by the user, the viewing direction and/or viewport position is determined by a defined viewing path. If partial automation is selected, the viewing direction and/or viewport position is determined by user input in combination with the defined viewing path. For example, a high-pass-filtered version of the user input may be added to the defined viewing path to obtain a partially-automated viewing direction and/or viewpoint position. Example systems and methods may be implemented using a head-mounted display (HMD).

  • Publication number: 20220286712
    Abstract: Cross-plane filtering may be used to restore blurred edges and/or textures in one or both chroma planes using information from a corresponding luma plane. Adaptive cross-plane filters may be implemented. Cross-plane filter coefficients may be quantized and/or signaled such that overhead in a bitstream minimizes performance degradation. Cross-plane filtering may be applied to select regions of a video image (e.g., to edge areas). Cross-plane filters may be implemented in single-layer video coding systems and/or multi-layer video coding systems.

  • Patent number: 11347793
    Abstract: A method and apparatus are provided. The method provides display of preference information using depth perception, such as on a three dimensional display or in a virtual reality space. Objects are identified in an image or image sequence and assigned relevance information based on the preference information. Objects that are favored are shown in foreground planes of the display, to varying degrees based on the strength of the preference. Objects that are disfavored are shown in background planes of the display, also to varying degrees based on the strength of the preferences. Unidentified or neutral objects are shown at a base level, neither foreground nor background.
