A method of processing media data. The method includes determining, for a conversion between the media data and a media data file, that a preselection element includes an indicator, wherein the indicator indicates that a purpose of the preselection element is for providing a picture-in-picture experience where a supplementary video appears to be overlaid on a target picture-in-picture region in a main video; and performing a conversion between the media data and the media data file based on the indicator. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.

The present technology is to enable a transmitter device to read appropriate device information (EDID) from a receiver device with a reduced burden on the user. A memory unit that stores first device information and second device information, and a communication unit that communicates with an external device are included. The control unit determines to cause the external device to read the second device information, on the basis of reception of a rewrite signal for the first device information from the external device. It is possible to cause the external device (a transmitter device) to read appropriate device information (EDID) from a receiver device (a reception device) with a reduced burden on the user, and thus, user-friendliness can be increased.

Dynamic transcode throttling methods and devices for processing resource management and thermal mitigation in electronic devices such as eyewear devices. An electronic device monitors its temperature and, responsive to the temperature, configures a transcoding service to operate at different rates. A frame delay module is configured to add a delay between read frames prior to the transcoding service. This enables the electronic device to consume less power when temperatures are too high in order to provide thermal mitigation and can be performed without powering down the electronic device.

A method for reducing artifacts in streaming video implemented by a computing device involves determining whether a video quality assessment score for a current segment of a channel of a video stream with a first resolution and a first bit rate meets a quality threshold, replacing the current segment with a replacement segment with a lower resolution than the first resolution, in response to the current segment failing to meet the quality threshold, and publishing the replacement segment at the first bit rate as part of the video stream.

Methods and apparatus, including computer program products, for controlling a Pan-Tilt-Zoom (PTZ) camera. A video stream is provided by the PTZ camera. The video stream includes a main image and a smaller picture-in-picture overlay. The main image and the overlay show the same view. The overlay has both a higher frame rate and a lower resolution compared to the main image. A movement control instruction is received, by the PTZ camera, in response to an evaluation of at least one of the main image and the overlay.

A method and system may receive tiled video feed data sourced from one or more remotely situated vehicles. A teleoperator user interface is generated to include a concurrent display of a plurality of distinct video tiles from the tiled video feed data. A respective video tile displayed in the teleoperator user interface may include visual safety cues. A user interface segment that is displaying a respective video tile may be modified in response to teleoperator input.

A transmission device according to the present disclosure includes: a transmission unit configured to output, to a transmission channel, a plurality of packets each including a payload and a header added to the payload, the payload including pixel data corresponding to one line included in an image of one frame; and an insertion ratio calculator configured to calculate an insertion ratio of a padding code, the padding code being inserted into the payload to fill a difference between a transmission rate of the pixel data that is inputted to the transmission unit and a transmission rate of the pixel data that is outputted from the transmission unit to the transmission channel.

Provided are a processing device, an electronic device, and a method of outputting a video. The processing device includes a pull-down cadence detector configured to receive an input video stream generated by pulling down raw data from an external device, detect a pull-down cadence format indicating a rate at which the raw data is pulled down based on the input video stream, and output detection result information; and a pull-down cadence controller configured to output an output video stream having a second frame rate that is an integer multiple of a first frame rate of the raw data, based on the input video stream and the detection result information.

A display apparatus is provided. The display apparatus includes an input interface, a first storage, a display, and a processor. Pixel values corresponding to a predetermined number of lines in an image input through the input interface are stored in the first storage. The processor acquires a first patch of a predetermined size by sampling a number of pixel values located in an outer region of a matrix centering about a specific pixel value from among the pixel values stored in the first storage, acquires a high-frequency component for the specific pixel value based on the acquired first patch, and processes the input image based on the high-frequency component. The display displays the processed image.
