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.

A signal is transmitted at a high speed in a direction opposite to a transmitting direction of a main large-capacity channel. A first transmitting unit transmits a first signal including a clock component to an external device through a transmission path as a differential signal. A second transmitting unit superimposes a second signal including a clock component on the transmission path as an in-phase signal to transmit to the external device. A state notifying unit communicates with the external device through a pair of differential transmission paths included in the transmission path and notifies the external device of a connection state of its own device by a DC bias potential of at least one of the pair of differential transmission paths.

Intelligent control method and device, and electronic device are provided. The method includes transmitting display data and audio data in real time for a projection device through a data channel connected to the projection device; monitoring a state of the data channel and an output state of the audio data on the projection device; and controlling the audio data transmitted in real time to be switched to a playback device for output if the state of the data channel is a connected state and the output state of the audio data on the projection device is an ineffective output state.

A method includes receiving, at a master agent, announcements from candidate consumer agents indicating the presence of the candidate consumer agents. Each announcement includes display parameters for a display of the corresponding candidate consumer agent. The method further includes receiving at the master agent content parameters from a producer agent, the content parameters defining characteristics of content to be provided by the consumer agent. A mosaic screen is configured based on the received announcements and the content parameters. This configuring of the mosaic screen includes selecting ones of the consumer agents for which an announcement was received and generating content distribution parameters based on the content parameters and the display parameters of the selected ones of the consumer agents. The generated content distribution parameters are provided to the consumer agent.

A control apparatus includes an acquiring unit configured to acquire a plurality of identification data indicating display performances regarding image qualities of a plurality of display apparatuses, and a generating unit configured to generate a first identification datum indicating a display performance with which all the display apparatuses are compatible using the plurality of identification data.

There is provided an information processing system, an information processing method, and a program capable of appropriately performing luminance adjustment of HDR videos. The information processing system according to an embodiment of the present technology is a system that transmits, to an output source device of an HDR video, capability information including information indicating display capability of an HDR video when a display mode is set in which luminance adjustment of an HDR video is performed by PQ hard clipping. The present technology can be applied to a TV including a display capable of displaying an HDR video.

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.

An apparatus and method for managing pipes and planes within a virtual graphics processing engine. For example, one embodiment of a graphics processing apparatus comprises: a graphics processor comprising one or more display pipes to render one or more display planes, each of the one or more display pipes comprising a set of graphics processing hardware resources for executing graphics commands and rendering graphics images in the one or more display planes; and pipe and plane management hardware logic to manage pipe and plane assignment, the pipe and plane management hardware logic to associate a first virtual machine (VM) with one or more virtual display planes and to maintain a mapping between the one or more virtual display planes and at least one physical display plane.

A networked system includes a plurality of endpoint devices that each include a compute device and a display device. A virtual desktop configuration system is coupled to the plurality of the plurality of endpoint devices via a network and is configured to retrieve display device characteristics associated with the display device in at least one of the plurality of endpoint devices, configure virtual desktop display characteristics for a virtual desktop based on the display device characteristics, and transmit virtual desktop images having the virtual desktop display characteristics to the compute device in the at least one of the plurality of endpoint devices to cause that compute device in that endpoint device to display the virtual desktop images on the display device in that endpoint device.

An example electronic device may include a processor resource and aa memory resource with a set of instructions stored thereon that, when executed, cause the processor resource to retrieve a first brightness characteristic and a second brightness characteristic associated with the light source, associate the first brightness characteristic with a first nits level and the second brightness characteristic with a second nits level using a brightness conversion data block, determine a brightness control signal directly compatible with the light source, and cause the light source to operate via the brightness control signal.
