Disclosed are a display apparatus and a method of controlling the display apparatus. The display apparatus includes: a signal receiver configured to receive a broadcasting signal; a display configured to display an image based on the received broadcasting signal; a sound receiver configured to receive a sound spoken by a user; a first sound recognizer configured to be supplied with power when the display apparatus is in a standby mode, and determine whether the received sound is a reserved word candidate having a high probability of corresponding to a reserved word; a second sound recognizer configured to be supplied with power when the received sound is determined as the reserved word candidate and to determine whether the received sound is the reserved word; and a controller configured to control the preset operation to be performed when the received sound is determined as the reserved word.

Electronic apparatus and control method thereof

Methods, apparatuses, and computer-readable medium are provided for a frame rate up-conversion coding mode, where a bilateral matching mode can be used to determine motion information. In various implementations, local illumination compensation is disallowed from being used for a block when a bilateral matching mode is used for the block. In various implementations, a bilateral matching mode is disallowed from being used when local illumination compensation is used for the block.

Frame rate up-conversion coding mode

A method of encoding a digital video data applies adaptive pre-processing to data representing high dynamic range (HDR) and/or wide color gamut (WCG) image data prior to encoding and complementary post-processing to the data after decoding in order to allow at least partial reproduction of the HDR and/or WCG data. The example methods apply one or more color space conversions, and a perceptual transfer functions to the data prior to quantization. The example methods apply inverse perceptual transfer functions and inverse color space conversions after decoding to recover the HDR and/or WCG data. The transfer functions are adaptive so that different transfer functions may be applied to video data sets including different groups of frames, frames or processing windows in a single frame. Information on the data set and information on the applied transfer function is passed as metadata from the encoder to the decoder.

System for coding high dynamic range and wide color gamut sequences

A high dynamic range (HDR) signal processing device may receive a video signal and an operating mode indication. The operating mode indication may indicate a format of the video signal, for example, an HDR format or a non-HDR format. Whether to perform adaptive reshaping on the video signal may be determined based on the operating mode indication. For example, it may be determined to perform the adaptive reshaping if the operating mode indicates that the video signal is in an HDR format. It may be determined to bypass the adaptive reshaping if the operating mode indicates that the video signal is in the non-HDR format. Multiple types of HDR reconstruction metadata may be received via a network abstraction layer (NAL) unit.

High dynamic range video coding architectures with multiple operating modes

In various embodiments, a color gamut mapper includes a gamut map selection generator configured to analyze color space signals and generate a gamut map selection signal in response thereto. A color gamut transformer is configured to process the color space signals via a selected one of a plurality of gamut maps to generate gamut mapped color space signals, wherein the selected one of the plurality of gamut maps is selected in response to the gamut map selection signal. Other embodiments are disclosed.

Color gamut mapper for dynamic range conversion and methods for use therewith

Adaptive video processing for a target display panel may be implemented in or by a decoding/display pipeline associated with the target display panel. The adaptive video processing methods may take into account video content, display characteristics, and environmental conditions including but not limited to ambient lighting and viewer location when processing and rendering video content for a target display panel in an ambient setting or environment. The display-side adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to render video for the target display panel that is adapted to the display panel according to the ambient viewing conditions.

Display-side adaptive video processing

Video processing techniques and pipelines that support capture, distribution, and display of high dynamic range (HDR) image data to both HDR-enabled display devices and display devices that do not support HDR imaging. A sensor pipeline may generate standard dynamic range (SDR) data from HDR data captured by a sensor using tone mapping, for example local tone mapping. Information used to generate the SDR data may be provided to a display pipeline as metadata with the generated SDR data. If a target display does not support HDR imaging, the SDR data may be directly rendered by the display pipeline. If the target display does support HDR imaging, then an inverse mapping technique may be applied to the SDR data according to the metadata to render HDR data for display. Information used in performing color gamut mapping may also be provided in the metadata and used to recover clipped colors for display.

Backward-compatible video capture and distribution

Video processing techniques and pipelines that support capture, distribution, and display of high dynamic range (HDR) image data to both HDR-enabled display devices and display devices that do not support HDR imaging. A sensor pipeline (210) may generate standard dynamic range (SDR) data (230A) from HDR data captured by a sensor using tone mapping (226), for example local tone mapping. Information used to generate the SDR data may be provided to a display pipeline (260) as metadata (230B) with the generated SDR data (230B). If a target display does not support HDR imaging, the SDR data may be directly rendered by the display pipeline. If the target display does support HDR imaging, then an inverse mapping technique (276) may be applied to the SDR data according to the metadata to render HDR data for display. Information used in performing color gamut mapping may also be provided in the metadata and used to recover clipped colors for display.

Backward-compatible apparatus and method for providing video with both standard and high dynamic range

Adaptive video processing for a target display panel may be implemented in or by a server/encoding pipeline. The adaptive video processing methods may obtain and take into account video content and display panel-specific information including display characteristics and environmental conditions (e.g., ambient lighting and viewer location) when processing and encoding video content to be streamed to the target display panel in an ambient setting or environment. The server-side adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to generate video content in the color gamut and dynamic range of the target display panel that is adapted to the display panel characteristics and ambient viewing conditions.

Server-side adaptive video processing

Adaptive video processing methods and apparatus may be implemented by a decoding pipeline and/or an encoding pipeline. The adaptive video processing methods may take into account information including video content, display characteristics, and environmental conditions when processing and rendering video content for a target display panel in an ambient setting or environment. The adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to render video for the target display panel that is adapted to the display panel according to the ambient environmental or viewing conditions.
