A display device connected to a signal source outputting a video signal using an encryption protocol and that transmits the encryption key to the signal source includes: a transmission unit that transmits an own encryption key uniquely set for the display device and an encryption key transmitted from another display device connected to the display device as a lower device to the signal source and another display device connected as an upper device; and a stop instruction unit that instructs another display device corresponding to a predetermined encryption key included in an encryption key group based on the order of the own encryption keys included in the encryption key group to stop transmitting the encryption key received when the own encryption key is included in the encryption key group including a plurality of encryption keys transmitted from another display device connected as the lower device.

A display apparatus includes a display, an interface, and a processor configured to, based on a dongle in which an application is stored being connected to the interface, display the application stored in the dongle on the display based on information on the application received from the dongle, and based on receiving a user command for selecting the application displayed on the display, transmit a command for executing the selected application to the dongle through the interface, and based on receiving an execution screen of the application executed in the dongle through the interface according to the command, display the received execution screen on the display The processor is further configured to, based on receiving the user command, transmit, through the interface, a command for communicating with an electronic apparatus, so that the dongle is connected to the electronic apparatus.

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.

A video switching system, which can be part of an audio video receivers (AVR), enables simultaneous routing of multiple independent video streams (e.g., 8K video streams) received at HDMI inputs of the AVR from digital media sources to multiple selected digital display devices.

Methods and systems are provided for processing video games streamed from a cloud gaming system over a network. The method includes receiving an indication of selection of the video game, for a gaming session, through a user interface associated with a streaming device that is connected to a display screen via a pass-through device. The method includes receiving a signal that the gaming session is active, from a game streaming logic of the pass-through device. In one embodiment, the game streaming logic is configured to receive a compressed stream of the video game, decode the compressed stream of the video game, and provide image data for rendering by the display screen, and receiving user input by the game streaming logic for driving interactivity of the video game while said cloud gaming system executes said video game.

According to one embodiment, a server device is communicably connected to a plurality of video distribution systems each including a transmission device, a receiving device and an HDMI cable. The server device is configured to aggregate the plurality of elements of received first data, for each combination of the type of the receiving device and the type of the HDMI cable that is indicated by each element of the first data. The server device is configured to select a video format optimum for the video distribution system based on first data. The server device is configured to transmit second data to cause the optimum video format to be selected to the transmission device transmitting the particular first data.

Example video ingestion cables, display systems, and methods for harmonizing video formats for video ingestion are provided. An example video ingestion cable includes a first video interface connector cable to receive a first video feed formatted according to a first video format, a second video interface connector cable to receive a second video feed formatted according to a second video format, a format conversion circuit to convert the first video feed or the second video feed to a harmonized video format, and an output interface connector to transmit one of the first video feed and the second video feed as an output video feed formatted according to the harmonized video format to a display device. An example display system includes first and second video ingestion cables and a video ingestion circuit to select an input video feed for display.

The present disclosure provides a method of controlling a high-definition multimedia interface (HDMI). The method includes: reading, by a source device, extended display identification data (EDID) of a sink device when the sink device and the source device are connected; writing information about the source device in a status and control data channel (SCDC) structure; and reading, by the source device, the EDID again based on a predetermined field value included in the SCDC structure.

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for switching the output of an overriding multimedia device from a first input to a second input or a combination of the first input and the second input. An example embodiment operates by receiving sensor data detected by a sensing device and relating to a multimedia switching event. The example embodiment further operates by determining that sensor data detected by a sensing device corresponds to a multimedia switching action. In response, the example embodiment operates by generating a multimedia switching actuation signal that instructs an overriding multimedia device to switch its output from the first multimedia signal to the second multimedia signal. Subsequently, the example embodiment operates by transmitting the multimedia switching actuation signal to the overriding multimedia device.

Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device and the image display apparatus including the same according to an embodiment of the present disclosure includes: a first decoder to reconstruct image data received from an external electronic device, an encoder to compress the image data reconstructed in the first decoder, a memory to store the image data compressed in the encoder, and a second decoder to reconstruct the image data stored in the memory. Accordingly, despite of the increases of the amount of the input image data and the bandwidth thereof, the image data may be stored in the memory efficiently.
