  • Publication number: 20210383740
    Abstract: An exemplary computer console can generate one or more video streams having image data relating to an image or a series of images, also referred to as video, to be presented by an electronic display device. The exemplary computer console can provide the one or more video streams to the electronic display device over one or more transport streams. The exemplary computer console can effectively throttle a video stream bitrate of the one or more video streams to be less than of the standard defined transport stream bitrate of the one or more transport streams to allow the transport of the one or more video streams over the one or more transport streams.

  • Publication number: 20200380935
    Abstract: Host content is received from a host device coupled to an external display device. The host content is displayed on the external display device when an orientation state of the external display device is a first orientation state. Change of the orientation state from the first orientation state to a second orientation state is detected, e.g., with a sensor. Orientation data corresponding to the second orientation state is transmitted to the host device. Host content, which has been transformed by a rendering pipeline configured at the host device based on the transmitted orientation data corresponding to the second orientation state, is received from the host device. The transformed host content is displayed on the external display device in response to the orientation state of the display device being changed to the second orientation state. In other embodiments, the display may be updated continuously during the orientation change.

  • Publication number: 20200372876
    Abstract: An electronic device includes a display having an emulation component and a separate calibration component. The emulation component may provide a user of the device with a list of available emulation presets at least some of which is common across a large batch of displays. The calibration component may include at least one factory calibration setting that may be shared among one or more of the emulation presets. The user may optionally add to the list of emulation presets by filling up empty emulation slots in the emulation component. The user may also be given the option to recalibrate the display or to add custom calibration datasets using calibration targets different than factory targets. The custom calibration datasets may be optimized for one or more of the emulation presets. Thus, when the user selects a particular emulation preset, the display may automatically select the desired calibration dataset for optimal performance.

  • Patent number: 10665141
    Abstract: Source content super-sampled to a first resolution in an extended range space is obtained. A representation of a subpixel geometry of a display panel displaying the source content is obtained. The display panel includes, for every pixel, plural subpixel elements for three or more color primaries. A native resolution of the display panel is lower than the first resolution of the source content. An optimization operation is performed based on a set mode of the display panel and the representation of the subpixel geometry to derive a global optimization for determining, for a given pixel value based on the source content, an energy distribution between the plurality of subpixel elements of a corresponding pixel of the display panel. The source content in the extended range space is converted into intermediate content in a display space based on the global optimization. The intermediate content is further optimized based on error minimization.

  • Patent number: 10318224
    Abstract: A display system includes a host device that provides source data to a display. The source data includes one or more data-centric blocks free from a fixed-frame size imposition, fixed-frame rate imposition, or both from the display. Further, the source data includes presentation data. The display system includes a display that receives the source data, decodes the source data to discern a presentation time, a presentation positioning, or both for the presentation data. Further, the display presents the presentation data according to the presentation time, the presentation positioning, or both.

  • Patent number: 10176781
    Abstract: A display device is used in conjunction with: (1) optical sensors to collect information about ambient conditions in the environment of a viewer of the display device; and/or (2) privacy element identification and detection mechanisms (PEDMs) to collect information about the presence, orientation, and/or type of privacy elements being used in conjunction with the display device. For one embodiment, a processor in communication with the display device may create a view model based, at least in part, on the predicted effects of the ambient environmental conditions and/or presence of privacy elements being used in conjunction with the display device on the user's viewing experience. The view model may be a function of gamma, black point, white point, privacy element orientation and/or type, backlighting, field of view, number of viewers, color offset, or a combination thereof. The view model is also referred to as an ambient/privacy model.

  • Patent number: 9386318
    Abstract: Lossless image compression using differential transfers may involve an image compression unit receiving image data for an image in a sequence of images and transmitting the image data such that image data for at least some image tiles is transmitted using lossy compression due to resource limitations. The image compression unit may then receive image data for a subsequent image in the sequence and determine that the image data for at least some tiles does not change relative to the image data for corresponding tiles of the previous image. The image compression unit may then transmit image data in a manner sufficient to create lossless versions of tiles for which lossily compressed image data was sent previously.

  • Patent number: 9215501
    Abstract: Systems, methods, and devices for adding contextual matte bars to format image data to another aspect ratio are provided. For example, a method may include receiving image data of a first aspect ratio into a processor. The processor may receive a characteristic of a destination display of a second aspect ratio, an indication of ambient lighting, an indication of a characteristic of the image data, or any number of these factors. The processor may add matte bars to the image data to cause the image data to be formatted to the second aspect ratio. The appearance of the matte bars may depend on the factors received by the processor. The formatted image data with these contextual matte bars then may be sent from the processor to the destination electronic display.
