A media device includes: a microphone for recording a television; a memory having the important content; and a processor to: instruct the microphone to record audio data while the television is operating in a primary mode and store in the memory; instruct the television to switch operation from the primary mode to an important content mode; provide the important content to the television; subsequently instruct the television to switch from the important content mode to the primary mode using a primary protocol; instruct the microphone to record subsequent audio data; determine whether the television switched from the important content mode to the primary mode based on the initial audio data and the subsequent audio data; and instruct the television to switch from the important content mode to the primary mode using a secondary protocol when it is determined that the television has not switched.

Techniques are provided herein for secure display device communications. In one example, a video communications device provides, to a display device over a first connection, communication information that enables the display device to contact a server over a second connection. The video communications device further provides, to the display device over the first connection, a command configured to initiate an interaction with the server. The server obtains, from the display device over the second connection, a message initiating the interaction in response to the command based on the communication information.

A method for switching audio-visual interfaces and a circuit system are provided. The circuit system is disposed in a sink device. A protocol layer circuit of each of audio-visual interfaces in the sink device includes a status and control data channel control module, which is used to respond to the signals sent by the video sources continuously when the sink device is connected with audio-visual sources via the audio-visual interfaces. The multiple video sources can accordingly send FRL (fixed rate link) signals to the sink device in response to responses made by the sink device. The protocol layer circuit includes an FRL audio-visual packet detection module that starts to detect a rate of an FRL and resolve audio-visual packets for obtaining audio-visual data for the audio-visual interface that the sink device switches to.

An electronic apparatus includes an electronic apparatus includes: a communication interface; a memory storing at least one instruction; and a processor configured to execute the at least one instruction to: receive, from an external device through the communication interface, state information of the external device, execute a self-diagnosis mode to obtain error information of at least one of the electronic apparatus or the external device based on state information of the electronic apparatus and the state information of the external device, obtain setting information corresponding to at least one of the electronic apparatus or the external device based on the obtained error information, and control at least one of the electronic apparatus or the external device based on the obtained setting information.

Systems and techniques are provided for automation and recommendation based on device control protocols. HDMI-CEC device control data may be received from a connected electronic device that may be connected to an electronic display device. The HDMI-CEC device control data may be based on a HDMI-CEC device control signal from the electronic display device. The system may generate a control signal for a device. The control signal may be sent to the device for implementation.

A control signal transmission circuit and a control signal receiving circuit for an audio/video interface are provided. The control signal transmission circuit includes an audio/video interface encoder, a signal packaging circuit and a data allocator. The audio/video interface encoder is configured to receive an audio packet and supports a user-defined packet format. The signal packaging circuit is configured to receive a first control signal and package the first control signal into a control data packet according to the user-defined packet format. The data allocator is configured to receive a video data and a second control signal and to mix the second control signal and the video data to generate a mixed data packet. The audio/video interface encoder packages the control data packet, the mixed data packet and the audio packet according to an audio/video transmission protocol to generate an audio/video and control data.

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.

The present disclosure provides an image data processing device, an image data processing method and a display device. The image data processing device includes: a plurality of writing controllers corresponding to a plurality of image blocks into which an input image is divided, and each configured to obtain input data of one image block in each input image, determine a frame address of the input data stored in a memory, and transmit the input data to the memory in accordance with the determined frame address; and a plurality of reading controllers, each reading controller corresponding to one image block into which an output image is divided, and configured to determine a frame address of the output data of one image block in ach output image in the memory, and read output data from the memory in accordance with the determined frame address.

An electronic device and an operating method thereof. The electronic device includes a receiver for connection to a source device, a memory storing one or more instructions, and a processor configured to execute the one or more instructions stored in the memory to detect a first resolution of an input image received from the source device, determine whether to modify extended display identification data (EDID) of the electronic device, based on whether the detected first resolution corresponds to the EDID, upon determining that the EDID is to be modified, modify the EDID, and receive, from the source device, an input image of a second resolution, generated based on the modified EDID.

A multimedia system and a protocol converter are provided. The multimedia system includes a sink device, e.g., a television, various audiovisual devices connected to the sink device, and the protocol converter. The protocol converter is connected to the sink device, and processes the audio and video signals inputted from a specific audiovisual source and outputted to the sink device to be played. The audio signals can be processed and played by an audio playback device directly connected with the protocol converter. Furthermore, the protocol converter can process the audio signals being returned from the sink device of the multimedia system via an audio return channel or an enhanced audio return channel. Finally, the received audio signals are converted and outputted to one of various audio output interfaces supported by the protocol converter.
