A method for displaying a video stream of a scene captured by a monitoring camera on a display of a remote client device comprises receiving, at the client device, the video stream and information indicating an on/off status for an IR-illuminator illuminating the scene; setting a display setting of the display differently based on upon the on/off status for the IR-illuminator; and displaying the video stream on the display using the display setting. The client device comprises a display, a receiver which receives a video stream from the monitoring camera, and a control circuit. The control circuit executes an IR-illuminator status function to extract information indicating on/off status for the IR-illuminator illuminating the scene, a display setting function of the display differently upon the on/off status for the IR-illuminator, and a displaying function displays the video stream on the display using the setting set by the display setting function.

Methods, devices, and systems are disclosed for home based electric vehicle (EV) charging. According to one embodiment, a method is implemented on at least one computing device. The method includes determining a plurality of media items for simultaneous viewing on a user interface (UI) associated with a home-based EV charger. The method further includes transmitting the plurality of media items to the UI associated with the home-based EV charger.

A display control apparatus is configured to synchronize a transmission start timing to start a transmission of a video data to a display apparatus with a display operation start timing for the display apparatus to start a display operation in a display.

A data output apparatus includes: a video decoder that decodes a video stream to generate a first video signal; an external metadata acquisition unit that acquires one or more pieces of metadata corresponding to one or more first conversion modes; an HDR metadata interpreter that interprets one of the one or more pieces of metadata to acquire characteristic data and conversion auxiliary data; a DR converter that supports one or more second conversion modes and performs conversion processing of a luminance range of the first video signal based on the conversion auxiliary data to generate a second video signal; and an HDMI output unit that outputs the second video signal to a display apparatus.

Methods, devices, and systems are disclosed for home based electric vehicle (EV) charging. According to one embodiment, a method is implemented on an EV charger for determining relative position of a mobile device to an EV charger in accordance with embodiments of the present disclosure. The method includes receiving known location data associated with a global position of the EV charger, wherein the known location data has an accuracy better than 10 centimeters, receiving first global navigation satellite system (GNSS) timestamped data associated with the EV charger from a first constellation of GNSS satellites, determining first GNSS location data based on the first GNSS timestamped data, and determining first GNSS error data based on the first GNSS location data and the known location data.

Various methods, systems, and electronic devices include delivery of sequential subtitle images to a client device. To that end, a method includes obtaining a plurality of sequential subtitle images including a first sequential subtitle image and a second sequential subtitle image. The method includes generating a diff image by comparing the first sequential subtitle image against the second sequential subtitle image. The diff image includes content that is absent from the first sequential subtitle image and present in the second sequential subtitle image. The method includes sending, to the client device, the diff image and display metadata associated with the diff image. The metadata may include a temporal indicator that indicates a display time or display duration of the diff image, and may include a position indicator that indicates a display position of the diff image.

Devices are disclosed for home based electric vehicle (EV) charging. According to one embodiment, an EV charger includes a processor, a memory electrically coupled with the processor, EV charging circuitry electrically coupled with the processor, a network interface electrically coupled with the processor, and a broadcast transmitter electrically coupled with the processor.
