A source device for transmitting content to a sink device is provided. The source device may include an interface configured to perform high-bandwidth digital content protection (HDCP) authentication with the sink device, and a controller configured to determine an HDCP version supported by the sink device, convert the content so as to be encrypted in the HDCP version supported by the sink device in response to a determination that another HDCP version applied to the content is not supported by the sink device, encrypt the converted content in the HDCP version supported by the sink device, and control the interface to transmit the content to the sink device.

A display device and driving method thereof are disclosed. The display device includes a display screen, including a plurality of sub-pixels arranged in the form of a matrix, colors of the sub-pixels in the same column including all colors necessary for display by the display screen; a grating disposed on top of the display screen, including light-transmissive regions and light-shading regions that are arranged alternately, the light-transmissive regions being in parallel to each column of the sub-pixels; a rolling structure, located between the display screen and the grating; and a push mechanism, for pushing the grating and/or the display screen, so that relative position of the grating and the display screen is switchable between a first state and a second state, and switchover between a dual viewing field display effect and an anti-spy display effect is achieved for the display device.

Embodiments relate to a billboard circuit that stores context information received from various component circuits in an electronic device. The context information indicates an operating status of the corresponding component circuit, system or shared resources. The stored context information may be retrieved by one or more component circuits when events (e.g., turning on of a component circuit) are detected. By using the billboard circuit, a component circuit may detect changes in the operating status of other components circuits and configure or update its operations even when the changes occurred while the component circuit was asleep or disabled. The billboard circuit may monitor updating of the context information by the component circuit and initiate notification to other components circuits when certain entries of the context information is updated.

Aspects of the invention relate to a smart card that leverages emerging technology hardware to enhance secure release of sensitive data associated with the smart card. The smart card may include an OLED display. The device may include one or more biometric sensors. Embodiments may include pairing a device with a portal used to access sensitive data. When accessing the portal, the user may be required to verify that the device is present before gaining access to the sensitive data.

Present disclosure provides a method and an electronic device for performing imperfect emulation of a state of a model in an electronic device. The method includes determining, by an electronic device, a current state of at least one actual model of the electronic device and comparing, by the electronic device, the current state of the at least one actual model with at least one state of a reference model. The method also includes determining, by the electronic device, a target state to be achieved by the at least one actual model based on the at least one state of the reference model; determining, by the electronic device, a deviation of the current state of the at least one actual model with respect to the target state to be achieved by the actual model; and modifying, by the electronic device, the current state of the at least one actual model to emulate the target state to be achieved by the at least one actual model based on the at least one state of the reference model.

The present application relates to the field of communications technologies, and in particular, to an interface sharing method and a terminal device. A a first terminal device shares a first interface with a second terminal device. If the first terminal device obtains a notification message to trigger generation of a second interface, the first terminal device first determines whether the second interface belongs to a preset sharing-forbidden interface. If the second interface belongs to the preset sharing-forbidden interface, the first terminal device shares only the first interface with the second terminal device, or suspends interface sharing with the second terminal device.

In response to a vehicle being switched from an IGN OFF state (non-operating state) to an IGN ON state (operating state) in a state in which a mobile terminal has been activated, the use of wireless communication (Wi-Fi communication) by the mobile terminal via a network using an in-vehicle device as a base station can be started. In response to the vehicle being switched from the IGN ON state (operating state) to the IGN OFF state (non-operating state) in the state in which the mobile terminal has been activated, the use of wireless communication (Wi-Fi communication) by the mobile terminal via the network using the in-vehicle device as the base station is stopped.

In certain embodiments, a method includes receiving an input signal from an input device (e.g., cursor movement) communicatively paired with the first host computer, where the first host computer is communicatively coupled to a second host computer, determining that data is saved to a virtual clipboard, detecting when the cursor moves to an edge of the display of the first host computer and when the input signal corresponds to continued movement of the cursor beyond the edge of the display of the first host computer, sending a control signal indicating that data is saved to a virtual clipboard, receiving a request for the data saved to the virtual clipboard, and sending, by the first host computer to the second host computer, the data saved to the virtual clipboard.

Embodiments of apparatus, computer-implemented methods, systems, devices, and computer-readable media are described herein for facilitation of concurrent consumption of media content by a first user of a first computing device and a second user of a second computing device. In various embodiments, facilitation may include superimposition of an animation of the second user over the media content presented on the first computing device, based on captured visual data of the second user received from the second computing device. In various embodiments, the animation may be visually emphasized on determination of the first user's interest in the second user. In various embodiments, facilitation may include conditional alteration of captured visual data of the first user based at least in part on whether the second user has been assigned a trusted status, and transmittal of the altered or unaltered visual data of the first user to the second computing device.

A method and system of augmenting display content in a graphical user interface environment. Content produced by a graphical user interface is augmented with additional content before the content is displayed. In an example, a security marker may be rendered on top of an existing display content using the method described to protect high-value or sensitive information.
