A display device and a driving circuit are discussed. According to an embodiment of the present disclosure, it is possible to stably maintain the output signal of the driving circuit when the lock signal indicating the synchronization state of the clock signal is changed due to an operation error such as overcurrent in a display device using a point-to-point interface. In addition, according to an embodiment of the present disclosure, it is possible to prevent damage to the display panel due to an overload generated in the output signal of the driving circuit by an operation error. In addition, according to an embodiment of the present disclosure, it is possible to prevent overload of the driving circuit and damage to the display panel by controlling the operation of the driving circuit through a differential input voltage between the timing controller and the driving circuit.

A data transmission and reception method for a sink device which is connected to a plurality of source devices by means of a high definition multimedia interface (HDMI), according to an embodiment of the present invention, comprises the steps of: receiving an allocation of an internet protocol (IP) address; transmitting device information about a sink device to a control point through a network; and transmitting service information about a supportable service by the sink device to the control point through the network.

In this display method, an information processing apparatus converts, for each of plural display surfaces that are parts of an entire screen, a position and size of a window in a coordinate system of the entire screen into a position and size of the window in a coordinate system of the display surface according to arrangement of the plural display surfaces, and transmits, for each of the plural display surfaces, the position and the size of the window in the coordinate system of the display surface to a display control apparatus that has a display device that provides the display surface. And each of plural display control apparatuses receives contents data from a terminal, and displays an image rendered based on the received contents data according the received position and size of the window in the coordinate system of a display surface of the display control apparatus.

Examples relate to managing a display input An example system to manage a display input is provided herein. Management of display input includes a determination of a display mode selected. Management of display input also includes control of connections and transfer of data between an external device and an internal device. Management of display input further includes adjustment of a display setting based on display mode.

Approaches for processing video in a smart small form-factor pluggable (SFP) transceiver. The smart SFP transceiver may dynamically select, from a plurality of codecs available to the smart SFP transceiver, an appropriate codec for use in processing the video prior to the video being transmitted over a link. The selection of the codec may be based, at least in part, on assessed environmental attributes. The smart SFP transceiver may then use the codec selected by the smart SFP transceiver to process the video, e.g., the video may be encoded, compressed, or timing information generated.

A video signal conversion method, a corresponding video signal conversion device and a display system including the video signal conversion device, by which low-resolution video signals can be converted and combined into a high-resolution video signal, such that a high-resolution image combined by low-resolution images can be displayed on an ultra-high definition display screen. The video signal conversion method includes: receiving in parallel a plurality of sub-frames divided from a low-resolution image of a video signal; performing image processing on each of the received sub-frames; and synthesizing the plurality of sub-frames after being subjected to the image processing into a high-resolution image frame and displaying the high-resolution image on a display device.

In some embodiments, systems, devices, and methods are provided that allow a host device to communicate video information, network information, and USB information over USB via a USB host controller. The video information and the network information are encapsulated within USB and communicated by the USB host controller.

In some embodiments, the USB information communicated by the USB host controller is further communicated over a non-USB extension medium by an upstream facing port device and one or more downstream facing port devices.

A standby power controller (SPC) supplies power to an appliance such as a television, and cuts power to the appliance if the appliance is going unused. The SPC includes first and second sensors, each detecting a type of user activity (such as user presence and remote control usage), and a switch which controls power to the appliance in dependence on the detection status of the first and second sensors, and also preferably in dependence on the prior detection status of at least one of the sensors at one or more points of time in the past.

A display processing apparatus connected to a plurality of information processing terminals through a network, displays first image data received from a first information processing terminal of the information processing terminals on a display in a full-screen display mode in response to a switching request, transmits response information that includes non-display information indicating non-display of image data to a second information processing terminal other than the first information processing terminal in the full-screen display mode, and receives an update request from the second information processing terminal in response to the response information, the update request not including second image data to be transmitted from the second information processing terminal and including predetermined information having a data amount smaller than a data amount of the second image data.

The present disclosure relates to a signal processing device and an image display apparatus including the same. A signal processing device according to an embodiment of the present disclosure includes: an input interface to receive an image signal; a first image processor to generate first image frame data based on the image signal; a second image processor to generate second image frame data scaled down from the first image frame data based on the image signal; and an output interface to receive the first image frame data from the first image processor and the second image frame data from the second image processor and to output the first image frame data and the second image frame data, wherein the first image frame data output from the output interface is more delayed than the second image frame data output from the output interface. Accordingly, a timing controller may accurately and rapidly perform signal processing for a panel.
