A streaming media device includes a printed circuit board hosting components configured to access internet data. An audio/visual connector is linked to the printed circuit board, wherein the audio/visual connector is adapted for connection to an audio/visual device, wherein the audio/visual connector is adapted to operate with a first audio/visual interface having sufficient power to fully operate the printed circuit board and a second audio/visual interface having insufficient power to fully operate the printed circuit board. A power connector is linked to the printed circuit board, wherein the power connector selectively receives power based on the audio/visual connector utilizing one of the first audio/visual interface and the second audio/visual interface.

Methods, systems, and media for providing information are provided. In some implementations, a method for providing information is provided, the method comprising: associating a first recording device of a group of recording devices located in an environment of a user with a trigger term; receiving, from a user device, a query that includes the trigger term; in response to receiving the query, determining that audio data is to be transmitted from at least one recording device from the group of recording devices in the environment of the user; identifying the first recording device based on the inclusion of the trigger term in the received query; receiving the audio data from the first recording device; identifying a characteristic of an animate object in the environment of the user based on the received audio data; and presenting information indicating the characteristic of the animate object on the user device.

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.

Configuration of a multi-display system is facilitated by use of general television receivers (display devices). Multiple digital interface terminals to which each of multiple display devices configuring a multi-display is connected via a transmission path are provided. A video signal is output to each of the multiple digital interface terminals. Replacement of the video signals output from the signal output unit to the multiple digital interface terminals is controlled to display a correct video corresponding to each screen of the multi-display. For example, the replacement of the video signals is controlled according to a video replacement operation signal sent from any of the multiple display devices via the transmission path.

A system and method are provided for an AV device for use with a video player, one or more speakers, and encoded AV data. The encoded AV data includes multiplexed encoded video data and encoded audio data. The AV device is connected to the speakers via wireless channels. The AV device is able to determine channel delays associated with each wireless channel; synchronize program clocks of the video player and speakers; determine and modify buffer levels of each speaker; demultiplex the encoded AV data to obtain encode video data and encoded audio data; and provide prefetched portions of encoded audio data based on buffer levels.

A display apparatus includes: a display; an input interface; and a processor in connection with the display and the input interface and configured to: upon detecting access of a first power amplifier device, output a high-level Hotplug signal at a Hotplug port of the display apparatus; monitor whether a common-mode data packet from the first power amplifier device is received within a first preset duration; in response to the common-mode data packet being received within the first preset duration, send a heartbeat packet to the first power amplifier device, and monitor whether a heartbeat response is received within a second preset duration; in response to the heartbeat response being received within the second preset duration, determine that the first power amplifier device supports e-ARC function; and in response to the heartbeat response being not received within the second preset duration, determine that the first power amplifier device supports ARC function.

Methods and systems for routing key commands received from a remote-control device are provided. The method and/or system may include receiving, at a device, a key command from the remote-control device, generating a first message that includes the key command, sending, from the device, the first message to a keystroke router, and determining, at the keystroke router, a system network controller associated with the device. Moreover, the keystroke router may send the key command to the system network controller.

A remote controller, includes: a first interface; and a first wireless portion connected with the first interface, wherein the first interface is connected with a screen projection device, the first wireless portion is wirelessly connected with a display device, and the first wireless portion receives data to be projected by the screen projection device through the first interface, and sends the data to be projected to the display device for displaying.

An electronic apparatus includes: a signal output circuit configured to connect with an external apparatus connected to a display apparatus, a processor configured to control the electronic apparatus to: obtain information about a first image format supported in the display apparatus from the external apparatus, output a content signal having the first image format to the external apparatus through the signal output circuit to the display apparatus based on identifying that the external apparatus supports an interface protocol capable of transmitting the content signal having the first image format, and output a content signal having a second image format different from the first image format to the external apparatus through the signal output circuit based on identifying that the external apparatus does not support the interface protocol.

In accordance with increasing communication demand, means for efficiently providing mass downstream communication at a low cost are desired. Accordingly, a communication system providing supplemental downlink as well as multicast communication comprising a display control device for causing a display unit to display a video, and a communication terminal having an image capturing unit for directly capturing the video displayed by the display unit or capturing a video projected or reflected on a wall surface or the like is provided, wherein the display control device includes a video acquiring unit, a region identification unit, a video generating unit, and a display control unit, and the communication terminal includes a region identification unit, a decoding unit, and a mechanism for communicating a control signal for supplemental downlink by the above-described optical communication using means other than optical communication (means such as WiFi, mobile data communication or the like).
